This paper addresses the state of domestic technical developments in the five components of Intelligent Vehicle Highway Systems (IVHS): Advanced Traffic Management Systems (ATMS), Advanced Traveler Information Systems (ATIS), Advanced Vehicle Control Systems (AVCS), Commercial Vehicle Operations (CVO), and Advanced Public Transportation Systems (APTS). Each component and current operational tests are briefly described. Particular emphasis is given to three current large-scale operational field tests (Pathfinder, TravTek, ADVANCE) to illustrate the integration of the IVHS components.
T R A m , short for Travel Technology, is the operational field test of an advanced driver information and traffic management system. The evaluation of TRAVTEK is being performed through the execution of twelve integrated studies within six study areas.
