Overview
• Kansas City Scout is a bi-state Advanced

Transportation.
• Architected and designed 1997 to 2002.
• Constructed 2002/2003 and became operational
January 2004.
• Operational costs are shared by Missouri and
Kansas based on field device deployments.
KC Scout Field Devices
• KC Scout has field devices
deployed over 154 miles of
freeways in the Kansas City
Metropolitan area.

Project Objective
Provide a quantitative estimate of the
benefits and costs of the SCOUT
system, including both existing and
proposed components.
IDAS is used as Benefits “Accounting” Tool – Incorporates Regional Travel
Demand Model
IDAS Cost Module
Outputs
• Inventory of ITS equipment on the
transportation network
• Costs by year – Expenditure stream
(life cycle)
– Public and private sectors
– Capital and O&M costs
• Estimate of average annual cost
IDAS
Benefits Module Outputs
• Performance measures including:
– Travel time
– Travel time reliability – unexpected delay
– Accidents (fatality, injury, property damage)
– Emissions (HC, CO, NOx, PM10)
– Fuel use
– Agency efficiency
• Benefits are monetized to permit comparison.
IDAS Model of Kansas
City Region
• Used 2010 MARC Model
as basis for Benefit/Cost
Analysis
• Assumed that planned
projects will be completed
by 2010 allowing direct
comparison between
existing and planned.
Basis of Benefit
Parameters
•
•
•
•
Default parameters based on national database
KC Scout Monthly Reports for 2007 and 2008
Input of KC Scout staff
Surveys of commuters in Southeast Michigan and
Cincinnati regions regarding their diversion patterns
• University of Missouri-Columbia ITS evaluation report
• CS IDAS experience in a wide range of cities
Cost Parameter
Assumptions
• Based on recent costs used in Wisconsin and
Michigan analyses and reviewed/updated by KC
Scout
• All capital costs include 10% for design and
15% for contingency
• Operations and maintenance assumed to be 15%
of capital cost
• Model cost assumptions match closely with
actual budget
Analysis Results
Analysis Results Notes
• Incident management (IM) includes CCTV,
detection and supporting staff
• Motorist Assist Program (MAP) benefits evaluated
separately but use many of same supporting staff
and resources as IM
• DMS included separately with travel time benefits
only but builds upon IM capabilities
• TMC and supporting resource cost allocation is
arbitrary but benefit/cost ratio is still positive for all
Benefit/Cost Analysis
• Assumptions are conservative
• All deployments have strongly positive B/C
ratios
• All elements work together – major finding is
that overall B/C ratio is good
• Planned deployments, as expected, have lower
B/C ratios than existing deployments
• About 80% of savings are in travel time with
fuel savings second
