Scout Traffic Center Manager 816 347 2200 Kansas City ITS Deployments Traffic Management Center (24/7) I-70 Corridor (St. Louis to Co. Border) Customer Service Incident Management Motorist Assist Overview • Kansas City Scout is a bi-state Advanced Transportation Management System developed and operated by Missouri’s and Kansas’ Departments of Transportation. Overview • Kansas City Scout is a bi-state Advanced Transportation Management System developed and operated by Missouri’s and Kansas’ Departments of Transportation. • Architected and designed 1997 to 2002. Overview • Kansas City Scout is a bi-state Advanced Transportation Management System developed and operated by Missouri’s and Kansas’ Departments of Transportation. • Architected and designed 1997 to 2002. • Deployed in 2002/2003 and became operational January 2004. Overview • Kansas City Scout is a bi-state Advanced Transportation Management System developed and operated by Missouri’s and Kansas’ Departments of 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. KC Scout Field Devices • KC Scout has field devices deployed over 154 miles of freeways in the Kansas City Metropolitan area. • Over 200 CCTVs KC Scout Field Devices • KC Scout has field devices deployed over 104 miles of freeways in the Kansas City Metropolitan area. • Over 200 CCTVs • 60 Dynamic Message Signs KC Scout Field Devices • KC Scout has field devices deployed over 154 miles of freeways in the Kansas City Metropolitan area. • Over 200 CCTVs • 60 Dynamic Message Signs • 304 mainline vehicle detectors allowing travel time calculations over 79 miles of freeway. • Comprehensive web tools (www.kcscout.net) KC Scout Map 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
