Automated highway systems - an intelligent transportation system for the next century

Summary form only given. The California PATH program was established in 1986 by the California Department of Transportation (Caltrans) and the Institute of Transportation Studies (ITS) at the University of California at Berkeley to conduct research on transportation systems, which include automated highway systems (AHS), to find solutions for California transportation problems such as congestion, mobility and productivity of system, safety, air quality and environment, energy consumption, cost effectiveness and regional and state wide economic health. This paper focuses on recent activities on AHS at the California PATH. AHS will include control problems from the vehicle level to the highway network level. The topics described cover PATH work at all levels, but an emphasis is given to control problems at the vehicle level, which will offer a number of challenging opportunities to control engineers.
