The Project Sponsors – New York State Department of Transportation (NYSDOT), New York State
Thruway Authority (NYSTA), and Metropolitan Transportation Authority/Metro-North Railroad (MetroNorth) – in cooperation with the Federal Highway Administration (FHWA) and the Federal Transit
Administration (FTA) are preparing a Draft Environmental Impact Statement (DEIS) for the Tappan Zee
Bridge/I-287 Corridor Project in Rockland and Westchester Counties, New York (NY). The DEIS
incorporates by reference and summarizes a series of technical reports addressing the technical disciplines
in detail. This technical report addresses the affected environment, impact of project alternatives, and
mitigation measures relevant to the topic of traffic operations and safety.

The project corridor extends approximately 30 miles from the I-287/I-87 split in Suffern, east to I-287/I95 in Port Chester (Figure 1-1). The Tappan Zee Bridge, a 3.1 mile long Hudson River crossing is
approximately midway through this corridor. I-287 between Hillburn/Suffern and the I-87/Cross
Westchester Expressway split is referred to as the New York State Thruway. I-287 east of the I-287/I-87
split in Westchester County is called the Cross Westchester Expressway (CWE). The CWE is owned by
The purpose of the DEIS is to evaluate multimodal highway and transit alternatives that will address the
transportation and mobility needs of the 30-mile-long Tappan Zee Bridge/I-287 Corridor from
Hillburn/Suffern to Port Chester, NY. Additionally, the structural and security needs of the Tappan Zee
Bridge are evaluated, as are other existing highway improvement needs within the corridor. The DEIS
examines existing socioeconomic and environmental conditions within the corridor, evaluates potential
impacts of the transportation improvement alternatives (in addition to the No Build Alternative), and
investigates mitigation necessary to alleviate these impacts. The DEIS presents a tiered analysis of
environmental impacts: a Tier 1 transit analysis and a Tier 2 bridge and highway analysis.
The regional travel demand model adopted by the New York Metropolitan Transportation Council
(NYMTC) is the Best Practice Model (BPM). However, BPM is a regional transportation model, not a
simulation model and, therefore, is neither designed nor suitable for the analysis of roadway traffic
operations. Rather, it provides overall regional travel projections. At that detailed level a simulation
model such as Paramics is then needed to take those projected volumes and apply them to the street
network to determine their implications for traffic congestion. Thus, Paramics (a microsimulation traffic
analysis model) was selected to address this issue.
This technical report discusses the calibration of Paramics, modeling methodology, and performance
measures used to evaluate the DEIS alternatives using Paramics. AM and PM peak hour volumes, speeds,
and travel times were estimated for existing and future years. At a micro level, intersection Levels of
Service (LOS) and delays were calculated. These data were used to study traffic impacts and also served
as input to the air quality and noise analyses.
The Paramics model was developed originally from the BPM highway network and significantly
enhanced based on engineering mapping. A data collection program was developed in 2005 which was
used to calibrate the model. The model was also calibrated and validated against travel time and speed
data collected. The analysis years that the model was used for were 2010 (Existing Conditions), 2017 and
2047 No Build and Build conditions.

the NYSDOT, but is maintained and patrolled by NYSTA from Exit 1 to Exit 10. It provides a critical
link in the federal interstate highway system.
The corridor contains portions of these two interstate highways, each serving distinct functions. I-87, the
main route through the Hudson Valley, connects New York City and Canada extending between I278/Triboro Bridge and Champlain, New York. I-287 serves as a circumferential route serving the New
York and New Jersey metropolitan area. It serves suburb-to-suburb trips in addition to long distance trips
(i.e., from New Jersey and points west to New England) enabling vehicles to bypass New York City and
its congestion. In addition, I-287 provides a vital connection between Westchester County and Rockland
County as well as Northern New Jersey, Connecticut, and surrounding communities. There are
approximately 40 major regional and local roadways crossings with I-287/I-87 within the corridor; most
of them are connected by interchanges.
Figure 1-1 Tappan Zee Bridge – I-287 Corridor
The corridor includes significant portions of both Westchester and Rockland Counties, including the
communities of Port Chester, Rye, Harrison, White Plains, Greenburgh, Elmsford, Tarrytown, Nyack,
West Nyack, Nanuet, Spring Valley, and Suffern. The nature of the project corridor is one that spans the
gamut of development and population density. To the west, the project corridor from Suffern to Nyack is

largely suburban and rural in character. Developments of commercial sites are limited and residential
development less intense. The intensity of development increases from west to east as the corridor
approaches and then crosses the Tappan Zee Bridge. East of the bridge, the corridor is more intense and
urban in nature, especially in the White Plains area. Adjacent development and ramp spacing on the CWE
is also, more urban in character.

The Tappan Zee Bridge opened to traffic in 1955 and carried an average of 18,000 vehicles daily during
its first year of operation. Today, approximately 135,000 vehicles cross the bridge on an average
weekday, with volumes as high as 170,000 vehicles on some peak days. During the past 20 years, growth
in population and jobs, and changing commutation patterns have caused traffic volumes to grow
significantly in the corridor: more than 50 percent in the I-287 Corridor and more than 70 percent on the
Tappan Zee Bridge.
Five passenger rail facilities pass through the corridor. The commuter lines east of the Hudson River (the
New Haven, Harlem, and Hudson) are the responsibility of Metro-North. These lines terminate at Grand
Central Station (GCS). Amtrak also runs trains that provide intercity and commuter service from New
York Penn Station north along the east side of the river to Albany on the Hudson Line and north on the
west side of Westchester to Connecticut along the New Haven Line. The Port Jervis and Pascack Valley
Lines, also commuter lines, are west of the river. New Jersey Transit (NJTransit) operates these lines,
which terminate at Hoboken, New Jersey.
There are numerous east-west and north-south bus services provided throughout the corridor as well.
Long distance bus service is available between upstate New York and New York City, and many local
and regional bus services are provided by a combination of local government and commercial providers.
In addition, passenger ferry service is provided between Haverstraw and Ossining, coordinated with
Metro-North Hudson Line trains at the Ossining Station.
The roadway network, defined as the system of intersections, local roads, arterials and limited access
highways located within the study area that will be directly or indirectly impacted by the various build
alternatives. Existing roadways, travel patterns and interchange locations within approximately 0.5 miles
on either side of the Thruway/CWE (I-87/I-287) corridor extending from Hillburn/Suffern to Port Chester
encompass the required highway network needed to examine the alternatives.
The highway, and most of the adjacent and intersecting roadways, has been coded as an integral part of
NYMTC’s Best Practices Model, in order to produce the future demand forecasts. However, for the
purposes of the traffic impact analysis and micro simulation, a much more detailed coding, including all
of the minor local roadways, street geometry, signal timing, etc. is needed by Paramics. For this reason,
the BPM network will be supplemented by a sub-regional network model for the traffic analysis. This
will be further explained in the section on Analysis Methodology later on in this chapter.
To facilitate the review and inventory of the corridor roadway network, current aerial photos were
obtained. In addition, plans were collected regarding committed transportation improvements. Data, such
as number of lanes, traffic control devices, medians, and other features were cataloged by examination of
the aerial photos and plans and by field visits.
Several major regional and local east-west and north-south highways dominate the network in Rockland
and Westchester Counties. Highways in Rockland County include I-287/I-87, Route 59, the Garden State

Parkway, Palisades Interstate Parkway, Route 303 and Route 9W. Highways in Westchester County
include I-287/I-87, Saw Mill River Parkway, Sprain Brook Parkway, Route 119, I-684, Hutchinson River
Parkway, Route 100 and I-95.Figure 4-2 in Chapter 4 of the EIS show the major regional and local
highways in Rockland and Westchester Counties.

I-287/I-87 from Interchange 15 in Suffern to Interchange 11 in Nyack is three lanes in each direction. It
widens to four lanes in each direction from Interchange 11 to the Tappan Zee Bridge. On the bridge, there
are a total of seven lanes. The bridge is operated with four lanes in the eastbound direction during the
morning peak period and with four lanes in the westbound direction during the evening peak period,
through the use of a moveable barrier system.
In Westchester County, the roadway cross section is more variable:

Between the toll plaza and Interchange 8 – there are four lanes in each direction.
At interchange 8, the Thruway (I-87) and the cross Westchester Expressway (I-287) split up and
the numbering system begins again.
After interchange 8, the next exit to the east on the CWE (now called exits and not interchanges)
is Exit 1.
Between Exits 1 and 3 – there are three lanes in each direction.
Between Exits 3 and 6 – there are three lanes in each direction with an auxiliary lane between
each entrance and exit in the eastbound direction only.
Between Exit 6 and I95 (the CWE terminus) – there are three lanes in each direction.
The existing grades along the mainline vary from 0.5 to 3.0 percent in Rockland County (see Figure 1-2).
From Interchange 15 to approximately halfway between Interchanges 14a and 14b, the grade generally
rises in the easterly direction. From halfway between Interchanges 14a and 14b to Interchange 12, the
grade generally decreases in the easterly direction.
In Westchester County, the existing grades along the mainline vary from 0.25 to 3.0 percent, except near
Interchange 8 (CWE Split) where the grades along the expressway ramps exceed 5 percent. Generally, the
grade decreases in an easterly direction, except at certain locations, which include Exit 6 and Exit 9,
where the grade rises. A list of grades and length of grades is included in Tables 1-1 and 1-2.

There are 15 interchanges in the corridor in Westchester County and eight interchanges in Rockland
County from Nyack to Suffern. There are approximately 100 major signalized intersections located within
the half-mile radius of the corridor. Traffic signals are maintained by a number of jurisdictions in the
study area. Contact was made with each agency and information collected regarding traffic signal
operation and layout that would facilitate subsequent analysis of basic traffic operations.

Chapter 2 of this report presents a detailed review of the traffic data collection phase of the study and
reviews the Paramics traffic microsimulation models established for the DEIS, including its relationship
to the BPM regional demand model and the calibration of the Paramics models to enhance their
applicability to the study corridor. Chapter 3 presents the results of the traffic studies and its assessment
of the proposed build alternatives while Chapter 4 presents the range of mitigation measures
recommended along the corridor. Detailed appendix materials relating to the data collection, calibration
and impact analyses efforts are also included.

The Tappan Zee Bridge/I-287 Corridor Project is a part of the transportation planning process in the New
York metropolitan area. As such, with both the FHWA and FTA as federal co-lead agencies, it must be a
part of the Continuing Comprehensive Coordinated [3C] process defined in federal planning regulations.
Those regulations mandate that the Metropolitan Planning Organization (MPO) develop the planning
process, including the adoption of urban travel demand forecasting models.

In order to analyze potential traffic impacts of the Tappan Zee Bridge/I-287 Corridor Project, two key
steps in the process are conducted:

1. Forecast Travel Demand - The tool used to forecast urban travel demand in the region is the
Best Practice Model (BPM) developed by the New York Metropolitan Transportation Council
(NYMTC). BPM represents a state-of-the-art process for forecasting future urban travel based on
assumptions regarding land use and transportation facilities and services. Moreover, because
potential alternatives include both major highway and major transit improvements, a multi-modal
model was required, and the BPM is the best and only available model in the New York region
that can simultaneously assess improvements to both highway and transit. It has been adopted by
NYMTC as the transportation planning model for the New York metropolitan area. The Transit
Technical Report describes this model in detail.

2. Conduct Level of Service Analysis - BPM is a regional travel demand model, not a traffic
simulation model and is, therefore, not designed nor suitable for the analysis of traffic operations.
Rather, it is the right model to provide overall travel projections, and can do so to a detailed level.
At that detailed level a simulation model such as Paramics is then needed to take those projected
volumes and apply them to the street network to determine their implications for traffic
congestion. Thus, Paramics (a microsimulation traffic analysis model) was selected to address
this issue. This chapter describes the methodology adopted to calibrate the Tappan Zee Bridge/I287 Corridor traffic model to count data using Paramics.

Paramics is a microsimulation model. These models simulate the characteristics and interactions of
individual vehicles. They essentially produce trajectories of vehicles as they move through the network.
The processing logic includes algorithms and rules describing how vehicles move and interact, including
acceleration, deceleration, lane changing, and passing maneuvers.
30
31
32
33
34
When a vehicle is generated in a network, the simulation model assigns driver-vehicle characteristics.
Some common characteristics or attributes for each vehicle are: vehicle type (car, bus, truck), length,
width, maximum acceleration and deceleration, maximum speed, maximum turn radius, driver
aggressiveness, reaction time, desired speed, critical gaps (for lane changing, merging, crossing),
destination (route), etc.

The physical environment—the transportation network under study—is typically represented as a network
of links and nodes. Links are one-way roadways with fixed design characteristics and nodes that represent
intersections or locations where the design characteristics of the links change.

Vehicles, in the absence of impedance from other vehicles, travel at their desired speed on the network
links. However, their speed may be affected by the link-specified geometry (horizontal and vertical
alignment), pavement conditions, and other factors. For example, the simulation model computes the
actual vehicle speed as the minimum value from the desired speed and the speed computed for the
specified vertical and horizontal alignment.
43
44
45
46
Vehicles proceed through the network until they exit the system at their destination. In O-D-based
models, such as Paramics, the O-D matrix is input, and when a vehicle is generated at an origin, it is
assigned its destination. The vehicle then exits the network at the specified destination. The O-D matrix is
derived from NYBPM, the travel demand model adopted in the study.

Microscopic models simulate the interactions of individual vehicles as they travel in the analytical
network using car-following, lane-changing, and queue discharge algorithms. Most of the existing
simulation models employ fail-safe car-following algorithms. Such algorithms simulate car-following
behavior by maintaining a minimum safe distance between vehicles subject to stochastically generated
vehicle characteristics (e.g., maximum acceleration and deceleration rates).
52
53
Lane changing, which occurs in microsimulation models, is based on the gap-acceptance process. A
vehicle may change lanes if the available gap in the target lane is greater than its critical gap.
2.1.1 Traffic Characteristics
54
55
56
As a micro-simulation model, Paramics requires information related to traffic characteristics such as
driver behavior, path choices and temporal distribution of traffic. The following paragraphs provide an
overview of these characteristics.
2.1.1.1 Drive r Be h a vio r
57
58
59
Paramics uses two main factors to estimate driver behavior. These are Headway (H), expressed in
seconds with a default value of 1.0 second, and Reaction Time (R), also expressed in seconds with a
default value of 1.0 second.
60
61
62
63
64
65
Values of 0.63 seconds for Headway and 0.43 seconds for Reaction Time were used for all networks, to
account for the aggressive and fluid nature of drivers in this region. It should be noted that other studies
utilizing Paramics have indicated the use of low headway values to accommodate congested conditions.
The low headway factor allowed sufficient throughput capacity to be simulated, as was observed with
actual traffic counts. The reaction time was lowered in conjunction with the headway in order to allow
sufficient lane changing and gap acceptance to occur in the congested conditions.
2.1.1.2 Ro u te As s ig n m e n t Me th o d

In order to simulate traffic flow within the study area, a “Stochastic-Dynamic Route Assignment” method
was used. This method combines a probabilistic method of route assignment with a timed update of link
costs factor based on prevailing traffic conditions.
69
70
71
The route choice of a particular O/D trip is determined on a per vehicle basis based on the calculated link
costs of all the possible routes from the origin to the destination zone. In general, the route with the lowest
cost will be used. However, in reality it is unlikely that all drivers will choose the same route for a
2-2 Analysis Methodology

74
particular O/D trip, especially in a congested network where there is a limited choice of routes. The
stochastic component of the route choice accounts for this random variability and allows vehicles to
choose multiple routes between each O/D pair.
75
76
77
78
The calculation of the link costs is performed every three minutes and the route of each vehicle in the
network is updated (feedback) based on the current traffic conditions in the network. This feedback
allows the network routing to be “dynamic” with the routes between O/D pairs changing as traffic
conditions change. This method allows realistic driving patterns to be simulated.
2.1.1.3 Te m p o ra l Dis trib u tion o f Tra ffic
79
80
81
Paramics simulates individual vehicles and each vehicle is discharged to the network based on predetermined discharge rates. Hourly traffic profiles from automatic traffic recorder (ATR) counts for Route
17 and Route 4 were used to estimate vehicle discharge rates for the traffic simulation model.
82

84
The Paramics model was calibrated to 2005 conditions. This was done by adjusting the network, trip
tables and vehicle characteristics to replicate realistic conditions to the extent possible.
85
86
87
As the Paramics model is more of an operational model and than a planning model a greater level of
network detail was added to the Paramics model that was originally created from the BPM network
structure. Without this added detail it would not be possible to replicate the existing traffic conditions.

and 2 from Connecticut. It was determined that the traffic impacts in the study corridor would be
studied using two separate models, the Rockland and Westchester models. The split was made at
the Tappan Zee Bridge, with about a mile of overlap on each side of the Hudson River. Figure 2-1

One of the hard and fast requirements for traffic analysis is that the data used, not be more than three
years old. All of the data collected and used in the initial stages of this study came from 2002 or earlier.
For this reason, it was necessary to collect all new traffic data including, ATR counts indicating average
daily traffic (ADT) volumes as well as morning and evening peak hour counts, manual turning movement
(MTM) counts, signal phasing/timing plans, classification counts, speeds and truck percentages. Both the
Thruway Authority and the NYSDOT have permanent count stations set up along their facilities and this
additional data from these locations was used to supplement the new counts, done in 2005.
118
119
120
121
122
The most common permanent count stations (the ones used by both the NYSTA and NYSDOT) are wire
loops cut into the pavement and hooked to a recording devise for continuous recording, 24 hours per day,
7 days per week and 52 weeks per year. These can be accessed at the site or remotely through a wireless
connection and data can be downloaded whenever it is needed. A setup like this allows the engineer to
look at volumes, speeds, classification and lane usage for whatever time periods he is interested in.

Written requests were made to relevant transportation and planning agencies along the corridor for plans
for new traffic generators expected to be in place by 2017 (the estimated time of completion [ETC] of this
project). In addition requests were made for all funded roadway construction plans. Table 2-1 presents a
summary of the type of data collected from the agencies. A detailed summary and location map showing
traffic count data and signal phasing/timing plans is included in Appendices. Roadway inventory,
including data on lane configuration and the type of intersection control, were documented using aerial
photographs, field visits and construction plans obtained from various agencies.

There were 301 separate counts taken at 185 locations in Rockland and Westchester counties. The
counters were placed for 1 week on the I-87/I-287 mainline and ramps and for three midweek days
(Tuesday, Wednesday and Thursday) on the local roads and arterials. There were eight counters placed
on the mainline; three in Rockland and five in Westchester. Additional permanent count stations will be
used to supplement the mainline counts in Rockland and on the major highways in both counties. Table
2-2 shows the breakdown of the various ATR counts collected. Figures 2-2 and 2-3 show the locations of
the ATR counts for Rockland and Westchester respectively while Figures 2-4 and 2-5 show the AM and
PM peak volumes along the highway corridor in Rockland and Westchester Counties, respectively.

Each location was monitored on a daily basis to insure that the tubes were not broken, the battery had not
died and the machine was working properly. During the time the machines were out on the roadways, a
calibration count was done for each one for one hour in the AM peak hour, one hour in the PM peak hour
and one peak hour over the weekend. This calibration is necessary so that the percentage of vehicles with
more than two axels can be factored into the counts. The tubes attached to the ATR’s, count one vehicle
for every two pulses caused by the tires riding over them. A truck with four axels would be counted as
two vehicles. The calibration effort involves a person standing next to the machine and manually counting
and classifying the traffic as it passes. In this way, the numbers of multi-axel vehicles are known. The
total number counted by the machine is then divided by the total number counted by the person and a
correction factor is calculated. As previously stated, this was done in the morning and afternoon, the
appropriate factor was then applied to the time period and interpolated factors were used for the off peak
hours in between. This will produce a machine count as close to a manual count as possible.

Manual Turning movement counts were taken at 50 intersections within the study corridor; 22 in
Westchester County and 28 in Rockland County and are shown in Figures 2-2 and 2-3 for Rockland and
Westchester Counties, respectively. All manual turning movement counts were taken on one midweek
day during the same week that the ATR’s were collecting data. A complete set of all data sheets showing
the volume for each movement can be found in Appendix A. All possible movements (including left
turns, right turns and through movements were counted for the three hour (6:00 AM to 9:00 AM) peak
morning period and three hour (4:00 PM to 7:00 PM) peak evening period. At least two people were
assigned to each intersection to maximize the assurance of accuracy. Counting was done continuously for
the three hour peak periods in the morning and afternoon and recorded in fifteen minute intervals.
Information on the intersections and peak hour volume at each one is provided in Appendix A.

Traffic signal timing and phasing data was collected from the various agencies, for all signalized
intersections within the study area. Signal timing consists of the cycle length and the splits. The cycle
length is a complete sequence of signal indications: it is the total time it takes for any approach to go from
start of green through the green sequence, the yellow clearance sequence and the red sequence including
the all red part of the clearance. The splits are the specific amounts of time given to each of the
sequences, for example, 25 seconds of green, 3 seconds of yellow, and 32 seconds of red (including 2
seconds of all red) for a total of a 60 second cycle length. The phasing is the order of display of the
sequences determining which movements are permitted at which times. For example, Main Street left
through and right turns, Main Street clearance, Side Street left, through and right turns and finally Side
Street clearance. The final piece of signal timing information needed to be collected was the offsets.
That is the successive difference in time along the main street between the start of the green phases. For
example, intersection Y turns green 6 seconds after intersection X and intersection Z turns green 8
seconds after that.

The timing information was collected for 419 signals, 140 in Rockland County and 279 in Westchester
County. For most of the signals, the timing details were supplied by the agency or authority responsible
for the operation of the signal. In some cases, it was necessary to go into the field and collect the
information by hand. This signal data was inputted into the Paramics sub-regional model to produce the
traffic analysis. This will be described in detail later in this chapter.

Classification refers to the different types of vehicles that make up the traffic flow on the streets and
highways. For the purposes of this study, five classifications were used: passenger vehicle (included cars,
vans and SUVs), busses, motorcycles, medium trucks (trucks with no more than three axels and/or six
tires) and heavy trucks (trucks with more than three axels and six tires).

Manual classification counts of the above noted classes of vehicles were collected at a total of 28
locations on one day within the same time period that the manual counts and the ATRs were collected.
They were taken in all directions at 10 of the 27 intersections and in both directions at the three I-87/I-287
mainline locations (eastbound only at Loc# 287) in Rockland County (see Table 2-3). In addition, it will
be possible to get classification information from the permanent count stations in Rockland County. In
Westchester County, manual classification counts were taken in all directions at ten of the 22 intersections
and in both directions at all five count locations along I-287 (westbound only at Loc# 148) (see Table 24). By knowing the percentage of large vehicles (trucks, buses and RVs), and being able, to better
describe the traffic stream, it will allow us to be more confident in our calculations of the LOSs at the
various intersections, and mainline sections. A complete set of all data sheets showing the five
classifications for each location monitored can be found in Appendix A.

The counts were estimated at locations where counts were not available (synthetic counts). This was
necessary to establish a balanced set of counts with which to calibrate the model. The data used for
calibration was the average of Tuesday through Thursday peak hour count volumes for the AM and PM
models. The peak hours were determined from the peak hour on the mainline (7-8 AM and 4-5 PM).
These peak hour counts were then seasonally adjusted using factors derived from average Tuesday –
Thursday volumes for the year 2005. A factor was calculated for each month and the average count
volumes were revised using the appropriate factor.

Speed and travel time data were collected along the corridor during over the years (2006, 2008, 2009 and
2010). It was observed that the variation of travel time and of speeds varied significantly, which is the
case with the corridor. Therefore data was compiled over the many runs conducted and consolidated to
form a travel time and speed dataset to compare to. The results of the validation effort are presented in the
following segments.

Microsimulation results are highly sensitive to the amount by which the demand exceeds the capacity of
the facility. It is therefore vital that realistic demand forecasts be used in the analysis. The Paramics O-D
matrices are derived from a post-process performed on the BPM O-D matrices known as a sub-area
extraction. Figure 2-6 shows the Rockland County network within the corridor (red links), extracted from
the BPM.

The Regional BPM trip table spans over a four hour peak period and contains 4,000 zones. The sub-area
corridor extraction of the Rockland and Westchester networks also produces a subarea trip table that
reduces the number of zones to the hundreds, which is more in-line with the number of Paramics zones.
The subarea trip tables contain (1) external and internal zones, which refer to zones that serve as cordon
points to areas outside the subarea, and (2) traffic generators and attractors within the corridor. Once the
subarea is extracted, the following procedure was adopted to convert from 4-hour to hourly trip tables and
also to a demand that is in line with traffic operations as opposed to travel demand. This latter step is
required since travel demand models such as the BPM tends to allow traffic volumes greater than the
capacity of a street, since they measure demand rather than capacity-constrained through-put. However,
traffic operations models such as Paramics could fail quite quickly under these conditions, since they
must address the network’s traffic impedances -- traffic lights, left turn lanes, etc. In order to adjust the
origin-destination tables to more realistic traffic demands, the following outlined steps, to manually
reduce forecasted demands in the study area, was adopted.

The growth of traffic to nodes belonging to the same super-zone is assumed to be similar in the future.
For example, the Rockland traffic simulation corridor is split into 12 super-zones (Figure 2-7) Superzone 3 contains all BPM/Paramics nodes connecting Westchester (Figure 2-8). Super- zone 9 contains
BPM/Paramics nodes connecting Orange through PIP. Zone 2 contains BPM/Paramics nodes connecting
Orange through I287.

The BPM absolute growth is added to the Paramics base year one hour trip table. For example, BPM
zone A corresponds to Paramics nodes a, b, and c; BPM zone B corresponds to Paramics nodes d, and e.
Let’s say AB_BPM=350. And base year Paramics trips from a, b, c to d and e are 30, 20, 0, 30, 0, 20
respectively. The allocation of these new trips was performed as indicated in Table 2-5:

In this example, there are 20 base year trips from a to e in Paramics, which corresponds to 20 percent of
trips from A to B based on the Paramics trip table. Therefore, 20 percent of future new trips will be
assigned from a to e.
310
311
312
Up to this point, the future Paramics trips generated are 4-hour trips, which need to be converted to 1-hour
trips. The conversion is done by multiplying the result from the above process by a conversion factor. The
formula for conversion factor is as below:

The 4-hour Paramics future trips were then multiplied by the conversion factor to obtain a 1-hour trip.
This result was then further adjusted to reflect highway capacity constraints.

Initial Paramics runs of the network showed a number of locations where unable enter the network from
the origin zone, indicating a capacity constraint on the entering links. A combination of capacity
constraints and diversions where available were used to enable the broader network to absorb the higher
future demand volumes. Therefore, external trips entering the corridor at such locations were constrained
to the capacity of the link used to enter that section of the corridor. Where possible, further manual
adjustments to traffic assignment were made based on engineering judgment and local knowledge of the
traffic conditions in the area. For example, some of the New Jersey bound traffic heading south on I-87
(Thruway in Rockland County) were diverted onto Route 17.

To meet the requirements of such a complex model, it is important to represent the real world geometric
conditions and attributes of the network. These can be separated in the Paramics framework as node
attributes and link attributes.
329
330
331
332
333
334
Before the improvements to the node attributes were started it was important to enhance the node skeleton
structure (the number of nodes and their geographical location) so that the proper street network including
curves, ramps and complex lane configurations could be modeled. With the appropriate number of nodes
and location of those nodes the link curves and attributes were modified to correctly represent the real
world conditions. This was done by using data provided by aerial photography, network curb line
geometric data, and field site visits.
335
The link attributes were modified in the following order:
336
337
338
339
340
1.
2.
3.
4.
Number of lanes.
Posted speeds.
Classification (Highway, Urban Major, Urban Minor).
Match up curvature to CADD file data.
341
342
343
344
345
346
A set of categories were set up in Paramics to help correctly identify and classify the streets based on the
number of lanes, speed and classification of the streets. With the proper classification of the links, the
routing of vehicles in the model is a better representation of the real world paths. Next each link’s curb
points were adjusted to best fit the curves and curbs from the aerial photography and an AutoCAD
drawing. The importance of matching these points was prioritized with areas outside the half mile area
from the main routes getting less attention to detail.
347
348
349
350
351
Following the completion of the geometric changes to the network links, the node attributes could be
improved. These improvements included the correct coding of the signal timings, lane utilization
(auxiliary lanes, ramps, turn bays, etc.), improved stop line locations including stacked left turns. It was
important to make minor adjustments to intersection signal timings to insure that the correct capacity was
being given for each intersection and that artificial choke points in the network were not created.
352
353
354
355
With the nodes and links properly coded, a check of the network calibration was performed to check that
the enhancements had been correctly entered and that the zone to zone vehicle routes based on the
Paramics costs made sense. To adjust certain routes some localized link cost factors were added to the
network.

The objective of the model calibration is to insure a reasonable correlation between observed data and the
modeled traffic conditions. In order to complete this task, a set of calibration targets needed to be set.
The targets chosen were based on the FHWA “Traffic Analysis Toolbox Volume III: Guidelines for
Applying Traffic Microsimulation Modeling Software”, and from previous studies conducted by
Wisconsin DOT. It should be noted that these are only guidelines. The major parameters that were
validated against observed data included the following:

Modeled volumes
363
364
365
366
367
368
369
370
371
372


Travel Times/Speeds
Bottlenecks/Queuing
The most rigorous validation criterion is the comparison of modeled and observed volumes. When the
modeled values are compared against the observed targets at the same location, the difference between
these numbers must be within an acceptable tolerance. Typically percent difference has been used to
calculate the acceptable tolerance but since percent difference does not account for the relative
importance of high vehicle counts (for example percent difference of 10 percent for a volume of 50
vehicles is 5 vehicles and for 5000 vehicles is 500), the tolerance level is determined by the GEH statistic.
The GEH statistic is calculated using the following equation:
GEH Statistic:
373
Where: M = Modeled Flow (vehicles / hour)
374
C = Observed Flow (vehicles / hour)
375
376
377
378
379
380
381
382
Using the WISDOT and FHWA adopted criteria, 85 percent of the individual critical links in the model
must have a GEH of 5 or less. For this study’s purpose the critical links were identified as the mainline
and interchange ramp count locations. As shown in Rockland County and Westchester county calibration
sections of the document the model was able to meet the criteria. Key arterial and local street counts were
identified as secondary locations and although the validation of these locations was not required they are
presented as part of the calibration. It should be noted that for many of the existing and previous large
scale micro-simulation models within the five boroughs and other urban regions a target of 85 percent of
GEH of 5 or less is rarely met and that criteria is often lowered.
383
384
385
386
Speeds and travel times were matched as closely as possible and the results of the comparison are
presented in the sections below. Another validation measure that was compared with the travel demand
model, which served as a reference was overall distribution of trips. Visual inspection of traffic speedflow relationships and queuing along the corridor serve as an effective auditing tool.

On comparing the modeled results with the observed count data, it was determined that the Rockland
mainline modeled volume GEH results were well within FHWA guidelines. A sizeable number of Route
59 locations were within a GEH of 5, as seen in the tables below. The projected vs. observed ratios on the
crossroads leading up to Route 59 indicate that the difference between modeled and count volumes are
substantially different in most locations. However, the magnitude of these volumes is small compared to
the mainline and Route 59. Table 2-6 illustrates the level of calibration on the mainlines, as well Route
59. Comparisons of volumes are shown in the appendix.

On comparing the modeled results with the observed count data, it was determined that the Westchester
mainline modeled volume GEH results were well within FHWA guidelines, as shown in the tables below.
Although not to the same degree the route 119 and local counts were also seen to show a satisfactory level
of comparison with the observed counts. Table 2-7 illustrates the level of calibration on the mainlines, as
well as along Route 119. Comparisons of volumes are shown in Appendix A.

In comparing the EB and WB travel times and speeds for the mainline Rockland models the results were
deemed to be satisfactory. It should be noted that variations between the observed and model results were
deemed acceptable do to the daily variation in the area. Further the 2010 no build models were further
refined to represent the present day bottlenecks and queuing. Table 2-8 illustrate the level of calibration
on the mainlines for the travel times and speeds in Rockland County. No observed data was available for
the local street speeds and travel times hence the validation was done on a visual basis, from that process
the speeds, queues and overall operations of Route 59 were deemed to be satisfactory.

When validating models as large and congested as the Westchester and Rockland models it is important to
remember that the guidelines are just that guidelines and not steadfast rules. Following these guidelines
and professional judgments both the Rockland and Westchester AM and PM models were found to be
validated for the key areas and capable of being a good tool to compare the No Build scenarios with the
various analysis scenarios. As some minor differences were found and the first analysis year was set to
2010 some minor changes were made between the 2005 and 2010 models to insure the 2010 model better
represented the correct bottlenecks. These changes included but were not limited the following:




A better representation of EB and WB congestion on the mainline around interchange 11;
A more accurate representation of traffic thru white plains;
Improved toll plaza modeling of the EB toll plaza on the Tappan Zee Bridge; and
A better correlation between the bridge volumes in the Rockland and Westchester models.
With these improvements the validation both on a quantitative and qualitative sense was seen to be
complete and within applicable good-practice guidelines.

3.1 In tro d u c tio n
The calibrated Paramics model was refined to include programmed improvements within the Tappan Zee
Bridge/I-287 Corridor and planned DEIS improvements as applicable. Trip tables for each scenario were
obtained from individual BPM runs. The trip tables were further adjusted to account for the possible
rerouting of trips on parallel roadways, or peak spreading in the future when projected demands exceed
hourly capacities. The adjusted trip tables were assigned to the respective Paramics networks and further
network adjustments were made to the networks in order to prevent the network from breaking down. A
breakdown constitutes unrealistic conditions such as complete gridlock caused by excessive backups,
resulting in rerouting choices that would lead to breakdown of the network. In most cases, the simulation
does not run through the entire period and will not produce a complete set of results.
3.1.1 Analysis Years and Periods
12
Traffic analyses were completed for the following periods and scenarios:
13

2010 – Existing Conditions
14

2017 – Estimated Time of Completion (ETC) Year of highway and bridge elements
15
16

2047 – ETC+30 – Design year for highway/bridge elements and year by which transit elements
are expected to be online
17
All model runs were carried out for the AM (7 to 8) and PM (4 to 5) weekday peak hours.

The 2010 existing conditions models were seen as the best representation of current real world traffic
conditions and included a few modifications between the 2005 and 2010 models. These modifications
were listed in Chapter 2 of this report as part of the validation/calibration process.

The first four graphs in this section show the sectional link volumes and link speeds in the peak
period/directions for Rockland County. As shown in Figure 3-1, the AM period in the eastbound
direction (the AM peak direction) shows a steady increase in volume in the last section as vehicles
approach the bridge. The speed data show that in the eastbound AM peak hour signs of congestion
primarily occur around Interchange 13 and Interchange 11.

westbound direction data (the PM peak direction) in Figure 3-2 show a significant drop in speeds around
Interchange 11 and also show a substantial drop in speeds around Interchange 13 (weave-merge area).
The next four graphs show the equivalent link volumes and speeds in the peak directions for Westchester
County (Figures 3-3 and 3-4 for Eastbound AM and Westbound PM, respectively). The highway in
Westchester is a complex system of closely spaced on and off ramps, which causes the “saw tooth”
pattern of volumes and (especially) speeds in that area. While there are no substantial operational
problems, these speed and volume fluctuations show the somewhat unstable traffic flows in this segment.
The detailed volume and speed data used to generate these charts are included in Appendix C.

To better understand and analyze existing and future traffic conditions along the highway, the eastbound
and westbound directions were broken down into separate analyses sections to allow the analyst and the
reader to focus on speeds and volumes in key segments and effectively smooth out the very detailed
speed/volume data presented in the charts presented above and the equivalent tabular data in Appendix C.
Figure 3-5 shows the selected segments defined for the highway in Rockland and Westchester while
Tables 3-1 and 3-2 show the travel time and person miles of travel (length of segment x average volumes
over segment x vehicle occupancy) for these segments for eastbound and westbound conditions in the
AM and PM peak hours in Rockland and Westchester Counties, respectively.
The data in these tables also present a “mobility index” that measures how well as segment is moving
people under peak traffic conditions, based on a ratio of person miles of travel to travel time (in minutes)
over that segment. A given segment’s ratio is best observed in terms of how it changes over time (e.g.,
2017 vs. 2047) or under different scenarios (e.g., No Build vs. build). An increase in the ratio means that
the segment in question is moving greater amounts of persons with minimal increase (or possibly a
decrease) in travel time. This is discussed further under the No Build and build analyses in this report.

In order to properly model the 2017 and 2047 No Build conditions, the simulation modes had to reflect
any planned highway or roadway improvements from the TIP. From the data provided by the various
agencies the following list of committed projects were included in the 2017 and 2047 models for
Rockland and Westchester Counties.

Throughout the modeling process a number of assumptions were made for the 2017 and 2047 No Build
networks these assumptions are as follows:

The EB bridge volumes would be controlled by the Rockland models and the WB bridge volumes
would be controlled by the Westchester models. This allowed for the conditions in the key
directions to dictate, based on capacity, the demand entering Rockland and Westchester from the
bridge. This eliminated any issues that would be caused by the lack of capacity or peak hour
constraining on the BPM demand results.

Traffic signals were fine tuned to insure that signal timing was not the cause of unrealistic
congestion.

No new technologies for the toll plaza would be applied and that under the NB conditions the
plaza would remain the same with a similar configuration and wait times.

TIP projects were added to the models based on the latest available information and plans.

Rockland EB entering demand west of interchange 15 was capped to represent the capacity
constraints of I-87.

Rockland County
Rockland County Comparison of Mainline Volumes and Speeds
AM Eastbound
The AM Eastbound direction has also been referred to as the Peak AM direction in the Rockland model.
Hence, it is not surprising that there are some significant impacts when analyzing the mainline volumes
and speeds. The following bullets and following graphs (Figure 3-6) summarize the findings for the 2017
and 2047 AM eastbound trips:

The 2017 results do not differ greatly from the 2010 results although a lower speed, signalizing
heavier congestion was found approaching interchange 11.

By 2047 there will be a significant increase in demand from the western end of the model.

The 2017 and 2047 volumes from approximately interchange 13 to interchange 11 are very
similar and close to the 2010 volumes. This shows that this section of the mainline is currently at
capacity during the AM peak hour.

The continued increase in demand in 2047 causes a significant EB breakdown, with a negative
impact on the speeds starting at interchange 11 and extending back as far as interchange 14A.

The Interchange 13 bottlenecking can be associated with the weaving section of this interchange.

East of the Interchange 11 bottleneck speeds rise as the mainline opens up to 4 lanes and allows
for more traffic to get thru. The speeds increase more in 2047 than 2017 because of the greater
congestion upstream from interchange 11 in 2047 therefore chocking the traffic and resulting in a
lower volume on the downstream section immediately following Interchange 11.

The existing design of the Bridge Toll Plaza constraints the EB volume thru the corridor.

AM Westbound
The AM Westbound direction is the off peak direction in the Rockland model. Hence, it is not surprising
that there a significant amount of room for growth in volume. The following bullets and following graphs
(Figure 3-7) summarize the findings for the 2017 and 2047 AM Westbound trips:

The 2017 volumes are only marginally higher than the 2010 volumes.

The 2047 volumes are significantly higher for the entire length of the corridor.

The only significant speed difference between the 2017 and 2047 results is at the uphill approach
to Interchange 11.

The weaving section at Interchange 13 causes some turbulence and drops in speed.

Speeds recover dramatically west of Interchange 13.
Eastbound PM
The PM Eastbound direction is the off peak direction in the Rockland model. Hence, it is not surprising
that there a significant amount of room for growth in volume. The following bullets and following graphs
(Figure 3-8) summarize the findings for the 2017 and 2047 AM eastbound trips:






The 2017 volumes are only marginally higher than the 2010 volumes.
The 2047 volumes are significantly higher for the entire length of the corridor.
There are only minor differences in speed between the 2017 and 2047 models.
The weaving section at Interchange 13 causes some turbulence and drops in speed.
There is a small drop in speeds at the approach to interchange 11.
The bridge does not act as a capacity constraint for vehicles leaving Rockland County.
Westbound PM
The PM Westbound direction has also been referred to as the Peak PM direction in the Rockland model.
Hence, it is not surprising that there are some significant impacts when analyzing the mainline volumes
and speeds. The following bullets and following graphs (Figure 3-9) summarize the findings for the 2017
and 2047 AM westbound trips:

Due to capacity constraints the volumes from the bridge to Interchange 13 are similar for both the
2017 and 2047 conditions.

The 2047 speeds drop considerably between the bridge and Interchange 13 with further drops
around 14 A and 14 B when compared to the 2017 conditions.

West of Interchange 13 has very little capacity or congestion issues in 2017 and only minor ones
in 2047.

The traffic metering effects in the eastern half of Rockland reduce the likelihood of any major
impacts west of interchange 13.

Rockland County PMT, Travel Time and Mobility Index
Table 3-3 presents the PMT, travel time and mobility index values in existing (2010) and 2017 and 2047
No Build conditions in the AM and PM peak hours in the eastbound and westbound directions for
Rockland County. Data are shown for the same eastbound and westbound highway segments that were
defined in Section 3.2 above. These results clearly show the worsening of congestion in the two peak
periods/directions, most dramatically in 2047.
Rockland County Local Arterials and Signalized Intersections

Westchester County Comparison of No Build Volumes and Speeds
Eastbound AM
The AM Eastbound direction has also been referred to as the Peak AM direction in the Westchester
model. Although, seen as the peak direction, most of the mainline in Westchester is metered by the
various entry points such as the Tappan Zee Bridge and the closely spaced interchanges. Due to the
metering there are not any significant impacts from 2017 thru 2047 and only a marginal increase in
volumes The following bullets and following graphs (Figure 3-10) summarize the findings for the 2017
and 2047 AM eastbound trips:

2017 and 2047 models display similar speeds with only a small increase in volumes (usually
about 200-300 more vehicles).

The Eastbound directions is a very controlled corridor that although seems to have room for
growth the entry points do not allow for the anticipated growth.

Signs of a congestion issue at interchange I-87 8 are showing with a significant drop in speeds.
This is an issue present in the 2010 conditions as well.
Westbound AM
The AM Westbound direction is the off peak direction in the Westchester model. Unlike the Rockland
model however the Westchester growth is very controlled. The following bullets and following graphs
(Figure 3-11) summarize the findings for the 2017 and 2047 AM Westbound trips:

2017 and 2047 models display similar speeds with only a small increase in volumes (usually
about 200-300 more vehicles).

As long as the AM volume to the mainline is controlled there is very little impact over the years.
Eastbound PM
The PM Eastbound direction is the off peak direction in the Westchester model. Unlike the AM period do
see slightly more impacts with the PM Eastbound conditions coming close to the AM Eastbound
conditions. The following bullets and following graphs (Figure 3-12) summarize the findings for the
2017 and 2047 AM eastbound trips:

Since the major eastbound entry point (the Tappan Zee Bridge) is not congested there is room for
growth in this direction.

While 2017 volumes are similar to those of 2010 the 2047 volumes show significantly higher
volumes.

The higher 2047 volumes only have a minimal impact on travel speeds.

Westbound PM
The PM Westbound direction has also been referred to as the Peak PM direction in the Westchester
model. Although showing significantly more growth than the AM period there are still only very limited
impacts. The following bullets and following graphs (Figure 3-13) summarize the findings for the 2017
and 2047 AM westbound trips:

2017 volumes are marginally higher than 2010 volumes across the corridor.

The free capacity on the bridge allows for significant increase in volumes as you go from east to
west.

There is a capacity constraining issue around interchange 8E that limits the growth at this
location. This issue is associated with the local street network.
Westchester County PMT, Travel Time and Mobility Index
Table 3-4 presents the PMT, travel time and mobility index values in existing (2010) and 2017 and 2047
No Build conditions in the AM and PM peak hours in the eastbound and westbound directions for
Westchester County. Data are shown for the same eastbound and westbound highway segments that were
defined in Section 3.2 above.
These results show a modest growth in through-put and relatively stable travel times across the county,
reflecting the on-going highway improvements, although there are signs of an increase in instability of
traffic flows, especially in the center of the county (in the White Plains area).

The build alternatives analyzed for the DEIS are listed below. The assessment of highway and bridge
elements under the four build alternatives was carried out for both the 2017 and 2047 analysis years. The
combination of the highway/bridge and transit elements is only analyzed for 2047. For ease of
comparison and interpretation of traffic results, the transit alternatives will be grouped together based on
whether HOV/HOT lanes exist in Rockland County as a part of the alternative, or not. Alternatives B and
C (described below) will be grouped with the highway alternative without HOV/HOT lanes, and
Alternatives D and E with the highway alternative with HOV/HOT lanes.
The impacts of the build alternatives are discussed further in the context of geographical impacts
(Rockland and Westchester Counties).

All project build alternatives include a new bridge and a “common set” of highway improvements
(climbing lanes, C/D roads at Interchange 13, etc.) in Rockland County, which are described in detail in
Chapter 2 (Description of Alternative) of the DEIS. However, for two of the alternatives (D and E), the
development of High Occupancy Vehicle/High Occupancy/Toll (HOV/HOT) lanes in Rockland County
and across the bridge is also assumed to occur as part of the highway and bridge improvements in both
2017 and 2047. The other two alternatives have only the common set of highway and bridge
improvements.
The HOV/HOT lanes are separated from general purpose lanes for the exclusive use of buses, high
occupancy vehicles (registered carpools with three or more passengers) (HOVs), and other automobiles
willing to pay a toll for the lane’s use. The toll would be dynamic – varying over time based on the
volume of traffic in the HOT lane and the volume of traffic/level of congestion in the general purpose
lanes. It would also increase to keep the HOT lane from becoming congested. The dynamic aspect of
HOV/HOT lanes was modeled in Paramics, using the criteria set to keep the volumes less than 1600
vehicles/hour/lane and average speeds above 45 mph.
HOV/HOT lanes are a means of providing premium service on the roadway for buses and HOVs and
fully utilizing that capacity provided by allowing only as many other vehicles into the lane as can be
accommodated. The objective of HOV/HOT lanes is to improve the level of service for transit and HOV
operations yet allow usage by others willing to pay a toll. By allowing toll operations, HOV/HOT lanes
generate revenue and their higher occupancy levels avoid the perception of being underutilized that can
arise from typical HOV lanes. In this way, the tolls HOT lanes generate directly or indirectly subsidize
transit and HOV operations. Ideally, HOT lanes carry as many or more commuters than general purpose
lanes.

Alternative E: HOV/Bus Lanes (BRT buses operating in the HOV/HOT lane in Rockland)
The transit alternatives as listed above are evaluated for the long-term planning year horizon 2047. In As
noted above, for Rockland County there are two different alternatives -- the Busway and the HOV/HOT
Lanes. Under the Busway scenario an exclusive bus-only facility would be built alongside the mainline
and buses would enter and exit the facility at various stations depending on its route. Under the
HOV/HOT Lanes scenario, buses would travel in the HOV/HOT lanes in the middle of the freeway and
access stations and local roads using specially designed “Texas T” bus-only ramps. In Westchester
County there are also two different BRT options -- Busway and Bus Lanes. Under the Busway alternative
buses would operate primarily in a separate dedicated bus-only roadway, although buses would still
operate in on-street bus lanes into, out off and within White Plains. Under the Bus Lanes alternative buses
would operate primarily in the center of key local roads (e.g., Rt. 119) for the most part, resulting in a loss
of roadway capacity in those areas, and would utilize on-street bus lanes within White Plains in a roughly
similar manner as under the Busway option.
Throughout the modeling process the following assumptions were made for the 2017 and 2047 Build
networks -- assumptions that were effectively made on top of those made under the No Build:

Where needed the Transit Build Plans in Westchester would be refined to avoid grid-locking
conditions, reflecting the type of signal timing adjustments that agencies would likely make to
adjust to close to 40 years of traffic growth. These primarily occurred at key congested
intersections in White Plains where buses were integrated with the local roadway lanes.

A minimal green time would be given to the bus priority phases throughout Westchester County,
usually equaling 10 seconds of green time, followed by 3 seconds of yellow and 2 seconds all red.

The new toll plaza configuration would be the same throughout the different build alternatives.

Highway volumes entering the eastbound highway from I-287 and I-87 at Interchange 15 in
Suffern were capped to reflect the capacity constraints of I-87.
The following sections summarize the build alternatives results for 2017 and 2047 separately.

The Rockland County 2017 build analysis compared the two 2017 highway build scenarios (Alternatives
B-C without the HOV/HOT lanes and Alternatives D and E with the HOV/HOT lanes) against No Build
conditions. As described above, all project alternatives also include a substantial common set of highway
improvements in Rockland County.
423
Model Modifications – Alternatives B and C
424
425
426
The following list the modifications were made to the Rockland County Paramics 2017 models that did
not include the HOV/HOT lanes (Alternatives B and C) in order to insure that the models reasonably
assessed future build conditions:
427
428

EB 2017 NB demands from Orange County were applied to the Alternatives B and C scenarios,
to avoid a lower entering demand in the build than in the No Build.

Model Results – Alternatives B and C

436
437
The following graphs (Figures 3-14 through 17) compare the 2017 No Build volumes and speed within
Rockland County with the 2017 volumes under build Alternatives B and C (referred to as “A1” in the
figures) in the eastbound and westbound directions in the AM and PM peak periods. The detailed
volume/speed data associated with these charts are provided in Appendix C.
438
From the graphs the following impacts from Alternative A1 can be seen:

452

The Alternatives B and C model was built off of the 2017 No Build model and included any
signal modifications made for the No Build scenario.

For both AM and PM in both directions, a large improvement in the speeds thru Interchange 13
can be seen. This is due to the elimination of the weaving section on the mainline.

There is not a significant difference between the No Build and Alternatives B and C volumes in
the corridor in 2017.

The PM westbound approach to Interchange 11 shows a significant increase in speeds under
Alternative B and C, reflecting the climbing lane and the elimination of the lane drop that creates
huge delays under No Build conditions.

Westbound volume increases are substantial in the off-peak westbound AM peak direction,
reflecting primarily the improvements in the Interchange 11 area.

Table 3-5 presents the PMT, travel time and mobility index values in 2017 under No Build and
Alternatives B-C conditions as well as for Alternatives D-E (to be discussed in the next section) in the
AM and PM peak hours in the eastbound and westbound directions for Rockland County. Data are shown
for the same eastbound and westbound highway segments that were defined in Section 3.2 above. These
results show the across-the-board improvements in mobility under Alternatives B-C relative to No Build,
but with the largest growth in the westbound direction.

The following list the modifications that were made to the Rockland County Paramics 2017 models
developed to assess Alternatives D and E (common highway/bridge improvements + HOV/HOT lanes) in
order to insure that the models reasonably assessed future build conditions:
561
562
563
564
565
The following graphs (Figures 3-18 through 3-21) show the comparison of the 2017 No Build volumes
and speed relative to those under 2017 Alternatives D-E conditions (Highway Improvements +
HOV/HOT lanes). The detailed volume/speed data associated with these charts are provided in Appendix
C.

EB 2017 No Build demands from Orange County were applied to the Alternatives D and E
scenario to avoid the conditions where entering demand in the build would be lower than under
No Build conditions.

The models were built off of the 2017 Alt. B-C build model and included any geometric
improvements and signal modifications made for the B-C build scenario.

A minimal charge was applied to the HOV/HOT lanes in the off-peak period/direction to try to
encourage vehicles to use the HOT/HOT lanes.

The vehicle classes were divided into 10 different values-of-time groups to allow for a greater
sensitive to cost analysis of the HOV/HOT lanes. These groups and the percentage of drivers in
each were derived from Census Journey-to-Work data for the corridor.

The tolling costs were not varied for revenue purposes but only to obtain the desired usage of the
HOV/HOT lanes.

Table 3-5 presented in the previous section provides the PMT, travel time and mobility index values in
2017 under No Build and Alternatives D -E in the AM and PM peak hours in the eastbound and
westbound directions for Rockland County. Data are shown for the same eastbound and westbound
highway segments that were defined in Section 3.2 above. These results show that the mobility
improvements under Alternatives D-E are generally greater than under Alternatives B-C, primarily
reflecting the ability to increase PMT through higher volumes and an increase in average auto occupancy
due to the HOV vehicles in the HOV/HOT lanes.
616
617
618
619
Appendix C.

For both AM and PM in both directions, a large improvement in the speeds through Interchange
13 can be seen due to the C/D road’s elimination of the weaving section on the mainline.

The western portions of the HOV/HOT lanes in both directions will not have much demand in
2017.

The addition of the eastbound HOV/HOT lane improves the speeds through Interchange 11 when
compared to the No Build and the Alternatives B and C. This also results in a higher throughput
of volume crossing the bridge.

The introduction of the HOV/HOT lanes allows for significantly higher growth in 2017 in the
peak directions in both the AM and PM periods.

In the PM peak hour the introduction of the westbound HOV/HOT lane allows for a significant
improvement from the bridge to Interchange 11, which also reflects the elimination of the lane
drop and inclusion of the climbing lane, both of which also occur under Alternatives B and C.

In the PM peak hour the increased westbound volumes west of Interchange 11 causes a minor
slow down at Interchange 12 as the highway in that segment can now handle more volumes due
to the elimination of the bottleneck at Interchange 11.

The Westchester County 2017 build analysis compares future conditions under the two sets of
highway/bridge alternatives (Alt. B-C and D-E) with those under the No Build scenario. As noted earlier,
the proposed project includes no highway improvements for Westchester County beyond the toll plaza
and the eastbound flyover ramp connecting the HOV/HOT lane to Interchange 9 under Alternatives D-E.
Since the mainline geometry is the same under the No Build and build alternatives in Westchester,
volume and speed conditions for the two alternative groups can be evaluated on the same graphs.

Table 3-6 provides the PMT, travel time and mobility index values in 2017 under No Build and
Alternatives B-C and D-E in the AM and PM peak hours in the eastbound and westbound directions for
Westchester County. Data are shown for the same eastbound and westbound highway segments that were
defined in Section 3.2 above. These results show that there would be very little change in mobility
conditions from No Build to the two sets of build alternatives in 2017, reflecting the lack of any
improvements in the highway in Westchester County and the limited planning horizon year involved.
658
659
660
Appendix C.

Under the build alternatives further signal timing improvements were made particularly in White
Plains where gridlock conditions were a common issue.
The following four graphs (Figures 3-22 through 3-25) show the comparison of the 2017 No Build
volumes and speed relative to those under 2017 Alternatives B-C (no HOV/HOT lane in Rockland –
show as Alt. A1 in the charts) and D-E (with HOV/HOT lane in Rockland – shown as Alt. A2 in the
charts). The detailed volume/speed data associated with these charts are provided in Appendix C.
From the above graphs the following impacts from Alternatives B-C and D-E can be seen:

The westbound HOV/HOT lane on the bridge under Alternatives D-E allows for a significantly
higher volume west of Interchange 8.

Except for some very minor differences and the westbound volume difference west of
Interchange 8 noted above, in both time periods the No Build and two sets of build alternative
would have very similar volumes and speeds – an expected conclusion given the lack of any
changes to the highway under the build alternatives and the near-term planning timeframe.

Rockland County Comparison of Build Volumes and Speeds

692
The Rockland County 2047 build analysis comprises of comparing the two 2047 highway build
alternatives and four 2047 transit build alternative with the No Build scenario. The highway
improvements from 2017 are carried over to all of the 2047 builds as described above. Do to the
complicated geometry changes and the need to represent the HOV/HOT lane impacts this analysis is
going to be broken into two comparison groups, group one compares A1, B and C with the NB and group
two compares A2, D and E with the NB.
693
Model Modifications
694
695
The following list the modifications that were made to the Rockland County Paramics 2047 build models
in order to insure that the models reasonably assessed future build conditions:


2047 no build traffic signal timings were used as the starting point for Alternative B-C for 2047.

Alternative B-C 2047 was used as the starting point for all the 2047 Build transit alternatives
models.

Various route costs were modified to insure that through-trip travelers did not use the C/D
roadways as a short-cut through Interchange 13.

Various route costs were modified to insure that drivers did not aggressively use the PIP-toRoute 59 as an alternative east-west route to and from Orange County.

Route 59 signal times around Interchange 14 in Nanuet were adjusted to avoid gridlock.

Palisades Mall local network was enhanced under the transit alternatives to better handle the
station traffic – the types of changes that would typically be included as part of the project.

Under the transit alternatives, basic assumptions about station locations were made and demand
to those stations was added manually based on information provided by the BPM.

Signals in Nanuet, Nyack, and around the Palisades mall were fine-tuned to better handle the new
travel patterns and higher demands – once again the types of changes that would typically be
included as part of the project.
The following graphs (Figures 3-26 through 3-29) compare 2047 No Build volumes and speed with those
under Alt. B-C with just highway/bridge improvements (shown as Alt. A1 in the charts) and under Alt BC with highway/bridge and transit improvements, with BRT buses operating in a dedicated Busway
across Rockland County and the bridge. The detailed volume/speed data associated with these charts are
provided in Appendix C.

Table 3-7 provides the PMT, travel time and mobility index values in 2047 under No Build and
Alternatives B-C (common highway/bridge improvements only) in the AM and PM peak hours in the
eastbound and westbound directions for Rockland County. Data for Alternatives D-E (common
highway/bridge improvements + HOV/HOT lanes) are also presented for discussion in the next section.
Data are shown for the same eastbound and westbound highway segments that were defined in Section
3.2 above. The results for Alternatives B-C show mobility gains in all peak hours and directions relative
to NO Build conditions, especially in the westbound directions, reflecting the effect of the common
highway/bridge improvements, especially the westbound climbing lane and the C/D roads at Interchange
13.

For the AM period Alternatives B-C/No Transit and B-C with Transit all show very similar
volume and speed patterns.

The significant congestion shown in the AM eastbound No Build between Interchange 14 and
Interchange 11 is greatly reduced under the build alternatives, with greater volumes and higher
speeds in all three.

The increased volumes at Interchange 11 will result is a substantial drop in speeds across all
alternatives and somewhat lower speeds east of that point towards the bridge for the build
alternatives.

The AM westbound congestion located around Interchange 10-11 in the No Build is alleviated in
the build alternatives. The increased traffic flow through this area would result in a reduction in
speeds around Interchange 12.

There is a substantial benefit seen in the speeds across all periods, directions and builds at
Interchange 13 (C/D roadways).

For the AM westbound, and the PM eastbound and westbound trips the increased volumes and
weaving causes a drop in speeds around interchanges 14A and 14. This drop would be most
pronounced in the PM westbound direction where the operations of Route 59 in Nanuet also
contribute to the mainline congestion.

Improved PM signal timings due to station location around interchange 14B would result in an
improved mainline operation.

The capacity constraints associated with the transit improvements in Westchester under
Alternative C would result in a lower Bridge volume which accounts for the drop in WB volumes
for Alternative C from the bridge to about Interchange 12.

Table 3-7 provided above shows the PMT, travel time and mobility index values in 2047 under No Build
and Alternatives D -E (common highway/bridge improvements + HOV/HOT lanes) in Rockland County.
Data are shown for the same eastbound and westbound highway segments that were defined in Section
3.2 above. The results for Alternatives D-E show cross-corridor mobility gains in all peak hours and
directions relative to No Build conditions, especially in the westbound directions. The higher values for
Alt. D-E relative to Alt. B-C reflects the additional PMT made possible by the vehicles with higher
average occupancy levels in the HOV/HOT lanes. The substantial increase in eastbound travel times in
the AM peak in the segment east of Interchange 11 and across the bridge (due to HOV/HOT related
problems in Westchester) offsets most of the mobility gains realized in the rest of the eastbound corridor.
The following graphs (Figures 3-30 through 3-33) compare 2047 No Build volumes and speed with those
under Alt. D-E with just highway/bridge improvements, including the HOV/HOT lanes under these
alternatives (shown as Alt. A2 in the charts) and under Alt D-E with highway/bridge and transit
improvements with BRT buses operating in the HOV/HOT lanes across Rockland County and the bridge.
The detailed volume/speed data associated with these charts are provided in Appendix C.
From the above graphs the following observations for 2047 with Alternatives D-E without transit (shown
as Alt. A2 in the charts) and Alt. D-E with transit:

The throughput in Rockland County is similar across the build alternatives and significantly
higher than the No Build for the most part, given the additional capacity.

All build alternatives show a significant improvement in the area of Interchange 13 (C/D
roadways).

The drop in eastbound AM speeds immediately east of Interchange 13 is due to the substantial
increase in volumes through that section.

The substantial drop in eastbound AM speeds from Interchange 12 to the bridge reflects problems
at Interchange 8 in Westchester County, which does not have the capacity for the 1,500+
eastbound vehicles primarily coming from the eastbound HOV/HOT lane.

Due to the additional demand and the impacts of the local streets in Nanuet, the build scenarios in
the PM see a drop in speeds around interchanges 14A and 14. This is most evident in the
Alternative E in the westbound direction.

The build scenarios experience a drop in speeds near Interchange 12 in the eastbound direction,
reflecting trips to and from the Palisades Mall, madding traffic very sensitive to any shifts in
travel patterns.

Westchester County Comparison of Build Volumes and Speeds
865
866
867
868

870
871
In Westchester, highway and transit alternatives were compared against the No Build separately. Unlike
in Rockland County where the alternatives with HOV/HOT lanes could be expected to operate in a
similar manner (as would the alternatives without HOV/HOT lanes), it is not necessarily the case in
Westchester because traffic operations in Westchester would depend on a combination of factors
including the demand across the Tappan Zee Bridge, the capacity of roadways in Westchester, and so on.
872
873
The following list the modifications that were made to the Westchester County Paramics 2047 build
models in order to insure that the models reasonably assessed future build conditions:

Model Modifications

The PM demands were reduced for White Plains-originating trips to reduce the amounts of
unreleased traffic to a more realistic amount. The logic for these reductions is based on the fact
that the White Plains PM model zones mainly represent parking lots and garages that are already
close to or at capacity, providing little room for those lots to increase their traffic-generating
capacity beyond those levels.

The Alternative D-E demands from White Plains to Westchester-based destinations were set to
the same values as the Alternative B-C scenario to more realistically reflect the actual effect of
Rockland HOV/HOT lanes on conditions in the central Westchester area.

Traffic signal timing improvements to 2010 timing settings were applied throughout the model
along 119 and in White Plains (No Build and build) to better reflect the actual timings that would
exist after almost four decades of growth.

The transit alternatives were given a new priority/protected phase of about 10sec at any
intersection where the restricted bus lane would meet with general traffic – changes that would
normally occur as part of such projects.

A number of changes were made to the transit design through White Plains from North Central
Avenue to the Eastern side of White Plains.

An additional driveway was added for all 2047 models around the American Heart Association
Parking Facility on Westchester Avenue. Although not needed in 2017 the local traffic growth in
this area resulted in the need for a more real world representation of the driveways – changes that
would clearly be made with or without the proposed project.
The following graphs (Figures 3-34 through 3-37) compare 2047 No Build volumes and speeds with
those under Alt. B-C (shown as Alt. A1 in the charts) and Alternatives D-E (shown as Alt. A2 in the
charts. The detailed volume/speed data associated with these charts are provided in Appendix C.

Table 3-8 shows the PMT, travel time and mobility index values in 2047 under No Build and Alternatives
B-C and D-E in Westchester County. Data are shown for the same eastbound and westbound highway
segments that were defined in Section 3.2 above. The results show (1) a general lack of meaningful
differences in travel times and overall mobility among the No Build and two sets of build alternatives,
which is expected due to the lack of any highway improvements in Westchester County, and (2) the
substantial loss in mobility and through-put in the eastbound section from the bridge to Exit 6 in White
Plains under Alternatives D-E due to the impact of HOV/HOT lane-related increases in eastbound
demand coming from the bridge.
935
936
937
938
939
940

Except for the AM westbound direction there are no significant differences east of Interchange 8
between No Build and the two sets of build alternatives.

Due to the increase eastbound demand coming across the bridge (from the HOV/HOT lane) in the
AM peak under Alternatives D-E, the speeds from the bridge to Interchange 8 drop substantial
and are also lower and more unstable up to Exit 7 in the White Plains areas.

Due to the inability of large amounts of additional traffic to get to and from the highway in the
central core of Westchester, there are no substantial changes in volumes for most of the mainline
east of Interchange 8.
No information is provided here regarding highway operations under the 2047 build transit alternatives in

relative to those shown above for Alternatives B-C and D-E without transit in 2047. Detailed speed and
volume information for the 2047 transit alternatives are provided in Appendix C.

4.1 Hig h wa y a n d Brid g e Mitig a tio n
The Highway and Bridge Elements would improve overall highway mobility and operations in both 2017
and 2047, allowing the corridor to move more people and goods with typically minimal increases in (and
often decreases in) travel time. The use of a mobility index in the traffic analysis rather than just travel
speeds or tradition Level of Service (LOS) ratings provided a clearer measure of how much the proposed
project would improve the highway’s ability to efficiently handle future demand increases.
No locations were identified along the highway that would require mitigation, which is expected given
that the proposed project itself is a mitigation package for many of the operational and safety issues in
Rockland County. Further, many problems would have already been addressed by the on-going highway
improvements in Westchester County, where no changes to the highway are proposed.
The only location where the project would potentially impact highway operations would be under
Alternative D (HOV/Busway) and Alternative E (HOV/Bus Lanes) in 2047. Under these alternatives in
the morning AM peak hour, eastbound volumes from Rockland County heading over the bridge
(including those in the HOV/HOT lane) would increase by 1,300 to 1,400 vehicles over No Build levels.
After roughly 300 to 400 vehicles get off at Interchange 9 (via the flyover ramp), the remaining 1,000 to
1,100 vehicles in the HOT/HOT lane would merge into the highway’s general purpose lanes between
Interchange 9 and Interchange 8. These added volumes would put pressure on the recently redesigned
Interchange 8, resulting in speed reductions on the eastbound highway that would affect traffic flows on
the bridge and affect the highway’s operation in eastern Rockland County. The overall highway network
would be handling more volumes, but with an increase in travel time to the average driver. These impacts
would occur in 2047 but would not occur in 2017.
In terms of the possible need for mitigation of these impacts, the following factors need to be considered:

These impacts are projected over an almost 40 year planning horizon, with all of the uncertainties
and approximations involved in that type of process.

As the various build alternatives continue to be reviewed, all operating parameters of the
impacted highway segment in Westchester – e.g., weaving distances, merge/diverge operations,
etc. – would need to be further reviewed to assess potential refinements to the proposed concept
to ensure that the maximum mobility benefits of the HOV/HOT lane would be achieved while
maintaining overall traffic flow.

The identified impact of the HOV/HOT lane on highway operations is directly correlated to the
traffic volumes in that lane, the use of which is controlled by pricing. The pricing paradigm
assumed for the EIS was that the lane’s utilization in Rockland County and across the bridge
would be maximized as long as speed in the lane was maintained to at least 45 mph. Different
pricing strategies for this lane that would reduce these volumes and the associated traffic impacts
should also be further reviewed.
Some delays associated with toll plaza operation were projected for future years – delays that would be
less than under the present bridge but still an issue. However, it is very likely that some form of open-road
Mitigation Measures 4-1

47
tolling (ORT) system for the toll plaza would be in place well before 2047, which would eliminate these
toll plaza issues. In the interim, further enhancements in design, as well as additional marketing or
pricing strategies to increase E-ZPass usage could help maintain traffic operations at the toll plaza.

Traffic conditions with the project in 2017 generally would not warrant any mitigation at study area
intersections, other than the assumed fine-tuning of operations normally carried out by traffic agencies.
In 2047 at the identified locations, the way in which overall travel demand levels would be manifested at
the intersection levels are difficult to project. Many of the potential impacts would involve often modest
shifts or increases in volumes at already heavily congested intersections. The exact nature of those
adjustments would be worked out by traffic agencies as part of normal traffic management programs.

A number of potential traffic impacts associated with the Transit Elements were identified near proposed
BRT and BRT/CRT stations in Rockland County and along roadways with proposed on-street bus lanes
in or near downtown White Plains. During the future Tier 2 Transit environmental documentation, the
transit stations would be further designed, taking into consideration access/egress plans and adjustments
to nearby signal designs to minimize such impacts. Where a station would alter highway or roadway
design, such as the elimination of the Old Nyack Turnpike eastbound on-ramp near Interchange 14, more
extensive geometric changes at affected intersections would be needed.
Most of the potential traffic impacts of the Highway and Bridge Elements at signalized intersections in
Rockland and Westchester Counties could be mitigated through low-cost, transportation systems
management (TSM) type improvements. These would include signal timing and phasing refinements to
better match demand patterns at those locations, pavement restriping to optimize lane arrangements based
on traffic demands; and other measures to improve capacity such as corridor signal coordination and
parking restrictions at intersection approaches. These are the types of actions that traffic agencies
routinely carry out as part of short- and long-range operational and safety programs – actions that would
occur numerous times during the long-term planning year horizon of 2047.
In terms of the impacts that would be associated with BRT operations, comprehensive street management
studies would be needed to balance the competing demands for street and sidewalk space, especially in a
complex, tightly designed downtown White Plains. These types of issues would be addressed during the
future Tier 2 Transit environmental documentation.
