Abstract:

Development status and trend of connected automated vehicle highway (CAVH) system are presented. The system consists of four key modules: sensing module, fusion and prediction module, planning module, and control module. The system initially starts from a level of “simple vehicle, smart road” or “smart
system” and gradually migrates to a higher-level system of “smart vehicle, smart road”, which can significantly improve transportation efficiency, traffic safety and energy consumption. The development of the CAVH system is very important for China. Accordingly, the roles and functions of government agencies in transportation planning, construction and management need be well defined to develop the CAVH system.

Key words: connected automated vehicle highway (CAVH) system, automated driving, development of threedimensional integration, smart road
