Project objective. To develop an evaluation methodology for ITS projects that is based on the CORSIM traffic model.

Project abstract. Although extensive Intelligent Transportation Systems (ITS) technology is being deployed in the field, little analysis is being performed to evaluate the benefits of implementation schemes. This research project uses a simulation/optimization approach to develop a performance versus cost tradeoff curve that can be used as a decision tool for ITS design. Heuristic search techniques are being used to optimize ITS equipment deployment schemes (quantity and location of equipment) for a particular budget. Each equipment configuration is evaluated using CORSIM, a traffic simulation tool. This process continues until an "optimal" equipment configuration is determined for various budgets. The resulting tradeoff curve will be a valuable tool to assist in ITS planning. The lessons learned while generating the tradeoff curve will help ITS designers choose an efficient equipment configuration for their budget.

Tasks. 1) Comprehensive statement of the proposed ITS cost/benefit approach. 2) detailing of the evaluation of the proposed approach. 3) review of issues regarding our approach to allocating ITS equipment.

Milestones. This project will be completed by June 30, 2000.

Student involvement. One full effort GRA.

Relationship to other research projects. No immediate relationship; of course, other evaluation projects are being carried out at the Center.

Technology transfer. Transmittal to U.S. DOT and other interested parties. Publication in technical journals.

Potential benefits. Lack of agreed-upon evaluation standards is hampering the deployment of ITS. This project could help fill this gap.
