EVALUATION FRAMEWORK FOR IVHS

Evaluation is recognized as a key and integral element of the joint na tional effort of intelligent-vehicle highway systems (IVHS) research, development, and deployment. It is expected to play an important role in assessing the most cost-effective approaches for IVHS development. In this paper, an evaluation framework for IVHS is proposed, which ide ntifies three important dimensions for IVHS evaluation: (1) IVHS syste m architecture; (2) IVHS operating environment; and (3) impact on tran sportation system. Efficiency and effectiveness criteria, and the appr oaches to perform the evaluation are proposed for each dimension. Anti cipating that different evaluation schemes would be designed and imple mented by different organizations, it is intended that the characteriz ation and the suggested criteria would help to form a common basis for consistent comparisons. Considering the fast pace of IVHS development , it is urgent that a comprehensive evaluation framework be developed, and this paper is an attempt to meet this need. Hopefully, this paper will general comments and eventually lead to better frameworks.
