Evaluation Framework for IVHS

Abstract

Evaluation is recognized as a key and integral element of the joint national 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 identifies three important dimensions for IVHS evaluation: (1) IVHS system architecture; (2) IVHS operating environment; and (3) impact on transportation system. Efficiency and effectiveness criteria, and the approaches to perform the evaluation are proposed for each dimension. Anticipating that different evaluation schemes would be designed and implemented by different organizations, it is intended that the characterization 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 generate comments and eventually lead to better frameworks.
