  1. Promoting ITS Deployment via ITS Decision Websitewww.calccit.org/itsdecisionJeff X. Ban, Polina Mikkelsen, Marika Benko, Hamed BenouarCalifornia Center for Innovative Transportation, UC-Berkeley Mohamed AlkadriDRI, Caltrans

  2. What is ITS Decision? • Web-based tool for ITS decision making & implementation • ITS technologies clearinghouse • Tools to help potential implementers determine: • What is a particular ITS technology? • Whether it can used to solve my problems? • Designed for: • Professionals, planners, & engineers • Researchers & the public

  3. All Possible Solutions Final Solution! Candidate Solutions Feasible Solutions How to Search for A Solution? Background information/knowledge Feasibility Study Similar Cases Benefit cost analysis

  4. What are Available Now? • Tools for background information • National ITS Joint Program • Tools for benefit cost analysis • Caltrans: Life-Cycle Benefit-Cost Analysis Model • FHWA: ITS Deployment Analysis System (IDAS) • There are gaps of tools for conducting feasibility studies and case-based reasoning

  5. The ITSD Tool Complements and Completes Existing Tools ITSD Education Materials ITS Expert Systems Informed Decision ITS Case Based Reasoning User Cognition ITS Benefit Cost Models http://www.calccit.org/itsdecision/

  6. Should my city install ramp metering? • Need to consider: - traffic congestion - safety - public acceptance - operation and maintenance costs - others (in similar situations) encountered?

  7. ITS Educational Materials

  8. Ramp Metering

  9. Tools… ITS Decision ITS ES ITS CBR User Cognition B/C Model

  10. Matching ITS to Users’ Needs: ES & CBR • Expert System • Expert diagnosis of feasibility of an ITS technology to a particular problem • High level assessment • Both technical and institutional analyses • Case-Based Reasoning • Previous implementation experiences and lessens learned

  11. Expert System (ES)

  12. Expert Diagnosis Process Problem: Ramp Metering Installation Context: Where, traffic volume, crashes, etc. Diagnosis via expert knowledge database Recommendations: Feasibility scores from technical and institutional aspects

  13. Technical Analysis

  14. Institutional Analysis

  15. Recommendations Technical Institutional

  16. Case Based Reasoning (CBR)

  17. Our CBR Tool: Input For FSP

  18. Benefit/Cost Analysis

  19. Cost/Benefit ITS Decision ITS ES ITS CBR User Cognition B/C Model

  20. BC Analysis • The Last Step of ITS Decision • Several Products already Available • Caltrans: Life-Cycle Benefit-Cost Analysis Model, http://www.dot.ca.gov/hq/tpp/offices/ote/benefit_cost.htm • FHWA: ITS Deployment Analysis System (IDAS), http://idas.camsys.com/

  21. Usage of the Website • Numerous Internet visits • Many email inquires regarding ITS deployment • Users mainly from CA and US, nearly 30% from outside the country

  22. Internet Visits and User Demographics

  23. Again, Our Proposed ITS Decision Process! ITS Educational Materials ITS ES Informed Decision ITS CBR User Cognition B/C Model
