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

How to Search for A Solution?

All Possible Solutions

Final Solution!

Candidate Solutions

Feasible Solutions

Background information/knowledge

Feasibility Study

Similar Cases

Benefit cost analysis

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

Should my city install ramp metering?

Need to consider:

- traffic congestion

- safety

- public acceptance

- operation and maintenance costs

- others (in similar situations)

encountered?

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
