US-Japan Collaborative Research on Evaluation Tools and Methods: Comparison of Evaluation Tools and Methods Used in the United States (U.S.) and Japan

The United States (U.S.) and Japan have similar transportation challenges, and share a common belief that cooperative systems can deliver significant societal benefits for road users, especially in terms of safer, more energy-efficient, and environmentally friendly surface transportation. The two regions recognize that coordinated research can reduce costs and accelerate the development, deployment, and adoption of cooperative systems. The report is an outcome of the U.S.-Japan bi-lateral collaborative research on evaluation tools and methods. The report includes: Case studies of cost-benefit evaluations, including performance indicators, and measurement methods, of Intelligent Transportation Systems (ITS) and cooperative systems in the U.S. and Japan; Comparison and assessment of existing evaluation methods used for evaluating ITS and cooperative systems in the U.S. and Japan; Consistent glossary of terms for evaluations for use in the U.S. and Japan; and Consistent categorization and organization of performance indicators and measurement methods. The following are the key lessons learned from the assessment: Evaluations should be performed by an independent party who has no vested interest or stake in the project itself to eliminate potential bias; More rigorous experimental design is needed to better isolate benefits of cooperative systems or ITS implementations; Consistent dollar values should be applied when monetizing benefits; Acceptance of cooperative systems based on short-term exposures can be misleading; and Longer-term impact of cooperative systems should be examined prior to large scale deployment. The following are some opportunities for future collaboration between the U.S. and Japan, including: Development of consistent methodology for evaluations; and Application of the consistent methodology to evaluate a cooperative system deployment, either in the U.S. or in Japan (or one each in both nations).
