A Framework for Assessing Travel Behavior Response to Intelligent Vehicle Highway Systems 901509

Identification of a framework for assessing the consequences of adopting IVHS applications is presented. IVHS applications modify vehicle-highway capacities by enhanced information processing. Mobility opportunities change and, if acted upon, change individual travel behavior. Changes in individual travel behavior affect aggregate travel behavior and transportation network loadings. Decisions to change the transportation system cycle through a three step social action process involving goals and aspirations, knowledge and technology, and financial and legal capacity to act. Action is then constrained by opportunities available in the environment. The transportation systems model presents a framework for designing research to estimate the requirements and consequences of adopting the new technology.
