TRAFFIC MODELLING NEEDS FOR ADVANCED TRAFFIC MANAGEMENT SYSTEMS (ATMS). IN: EXPERT MEETING AND SYMPOSIUM ON THE SEMINAR ON FUTURE ROAD TRANSPORT SYSTEMS AND INFRASTRUCTURES IN URBAN AREAS, JUNE 4-6, 1991, CHIBA, JAPAN

Intelligent Vehicle/Highway Systems (IVHS) is an ambitious multi-year, multi-billion research/demonstration program which aims at improving the vehicle/highway system operation and management techniques for the post-interstate construction era. This paper begins with an introduction of the framework of IVHS which has four major components: (1) Advanced Traffic Management System (ATMS); (2) Advanced Traveler Information System (ATIS); (3) Commercial Vehicle Operations (CVO); and (4) Advanced Vehicle Control Systems (AVCS), and emphasizes the ATMS-related research and development plans to support the real-time traffic management systems and control strategies. The paper then reviews the state-of-the-art traffic engineering modeling software currently available from FHWA. The paper concludes by outlining the work that needs to be done in order to fully support the IVHS program.
