  1. IDAS – ITS Deployment Analysis System February 2004

  2. What is IDAS? • ITS Deployment Analysis System (IDAS) • FHWA sponsored software program released in May 2000 • A sketch-planning tool to estimate ITS benefit and cost impacts, for over 60 types of ITS investments • Assists public agencies with integrating the deployment of ITS into the transportation planning process • Relies on traditional MPO travel demand model outputs to construct data inputs • Runs on Windows 2000, NT, and XP operating systems

  3. What IDAS is NOT • Design Tool • IDAS is designed primarily as a planning tool • Replacement to the Travel Demand Model • IDAS is intended to operate as a post-processor to the travel demand model • Black Box • IDAS was developed in an open format that allows users to view and edit most all of the model defaults • IDAS is accompanied by an extensive User’s Manual

  4. - Network - Data - Technology - Network - Data - Mode Choice - Assignment TDM IDAS - Capacity Analysis - ITS Evaluation - B/C Analysis - Capacity Analysis IDAS is a Postprocessor and Extender to the Travel Demand Model (TDM)

  5. Why was IDAS developed? • Provide a sketch-planning analysis capability for analyzing alternative ITS deployment scenarios and for testing tradeoffs of traditional highway and transit infrastructure options • Design a system which is consistent with the functional, technical, and resource requirements of state, regional, and local agencies • Develop a tool which assists agencies in integrating ITS into the planning process • Make IDAS compatible with current transportation planning models and outputs

  6. Incorporating ITS in the Planning Process ITS Strategies IDAS Problem Identification Alternatives Analysis Recommendations Transportation Plan and TIP

  7. IDAS Capabilities • Comparison and screening of ITS deployment alternatives, in isolation or in combination with other improvements • Estimation of impacts and traveler responses to ITS • Estimation of life-cycle costs • Inventory of ITS equipment, and identification of cost-sharing opportunities • ITS deployment and operations/maintenance scheduling • Documentation for transition into design and implementation

  8. How IDAS Works • Allows the user to import data from the travel demand model to recreate the model network within the IDAS software • Provides the opportunity to build different alternatives by choosing from a menu of various types of ITS components and deploying them on the network • Maintains a database of system impacts and costs related to each type of deployment based on national evaluations • Performs internal network assignment and analysis to estimate impacts of ITS • Reports outputs in terms of the incremental change in performance measures and the annual benefit/costs

  9. Speed and Volumes IDAS Overall Structure Travel Demand Model Input/Output Interface Alternatives Generator Benefits Module • Assignment • Mode choice Cost Module • Equipment inventory • Capital and operations and maintenance (O & M) costs • Life-cycle costs Performance Measures • Travel time/mobility • Emissions/fuel • Accidents • Travel time reliability Alternatives Comparison Module • Benefit/cost analysis • Incremental performance impacts • Sensitivity/risk analysis

Types of ITS Components in IDAS Advanced Public Transportation Systems Regional Multimodal Traveler Information Incident Management Freeway Management Electronic Toll Collection Emergency Management Arterial Management Electronic Fare Payment Railroad Grade Crossings Supporting and Generic Deployments Advanced Vehicle Control and Safety Systems Commercial Vehicle Operations

  12. IDAS Input Data • Analysis Network – Output from travel demand model • Node coordinates • Link characteristics • Turn prohibitor (optional) • Origin-destination (O-D) number of trips • Zone-to-zone travel times (optional for in-vehicle auto trips) • Default Parameters, Impacts, and Costs – User may adjust • Speed-flow curves • Rates (emissions, fuel, safety) • Impacts of ITS options • Dollar value of benefits • Unit cost of equipment

  13. Example ITS Deployment Screen

  14. IDAS Benefits Module Outputs • Systemwide performance measures including • Mobility • Travel time • Travel time reliability • Accidents (fatality, injury, property damage) • Emissions (HC, CO, NOx, PM10) • Fuel use • Agency efficiency • Viewed by • Market sector (mode) • Facility type • District (user defined)

  15. IDAS Cost Module Outputs • Inventory of ITS equipment on the transportation network • Opportunities for equipment and cost sharing • IDAS default cost estimates based upon National ITS Architecture • Costs by year - expenditure stream • Public and private sector costs • Capital and operating and maintenance (O&M) costs • Estimate of average annual cost

  16. Benefit/Cost Summary

  17. IDAS ITS Library • IDAS uses look-up tables for the impacts of each ITS component • Data sources • Literature • Past deployments • Simulations

  18. Where IDAS Has Been Used

  19. Sample IDAS Applications • ITS alternatives analysis for Long Range Plans: Tucson, AZ; and Hampton Roads, VA • ITS Pre-deployment study: Detroit, Ann Arbor, Flint and Lansing, MI • Optimal combination of ITS for corridor studies: Minneapolis/St. Paul, MN • Evaluation of existing ITS components: ARTIMIS in Cincinnati, OH region and AZTech in Phoenix, AZ • ITS cost information for statewide ITS strategic deployment plans: Kansas and Missouri • Benefits of full operational deployments: Tucson, AZ; Seattle, WA; and Cincinnati, OH

  20. Sample IDAS Applications • Major Investment Study (MIS): I-70 Corridor in Missouri and I-710 in Long Beach, CA • Freight/Goods Movement Study: Seattle, WA • Evaluation of HOV Operations: Minneapolis/St. Paul, MN • Evaluation of Ramp Meters on I-95: Dade County, FL • Analysis tool for a Congestion Management System: Kansas City, MO • Evaluation of a Temporary ITS: Reconstruction of I-496 in Lansing, MI • Supporting Documentation for AQ Funding Application: Hampton Roads, VA

  21. IDAS Case Studies • Case Study 1: Ohio-Kentucky-Indiana Regional Council of Governments’ (Cincinnati/Northern Kentucky region) Evaluation of ARTIMIS and ITS Program Plan • Case Study 2: Michigan Department of Transportation Evaluation of the Temporary ITS for the Reconstruction of I‑496 in Lansing, Michigan • Case Study 3: Evaluation of Emissions Impacts of an Incident Management System in Hampton Roads, Virginia • Case Study 4: Mid-America Regional Council’s (Kansas City) Enhanced Congestion Management System
