摘要：	Advanced Vehicle/Highway Systems (AVHS), an umbrella term for several interdependent vehicle and road technologies, offer potential for reducing congestion and the air pollution it engenders, and for improving highway safety. The term AVHS includes technologies for: automatic vehicle identification and billing; weighing vehicles in motion; collision warning and avoidance; driver information and route guidance; advanced traffic operations control and optimization; and automatic vehicle control--both steering and headway. The Office of Technology Assessment (OTA) concludes that (1) AVHS technologies now available can increase roadway efficiency and throughput by 10 to 20%, make travel time more predictable, improve safety, and cut down harmful emissions, although by themselves they cannot solve our urban traffic problems; (2) substantial short-term national advantages could come from Federal policies and programs to encourage implementation of advanced traffic operations control systems; and (3) Federal effort and dollars invested in assisting State and local government in moving ahead with AVHS could do double duty, supporting much needed programs to address urban traffic congestion as well as boosting industry by helping create the public infrastructure necessary to communicate with advanced products that are almost market ready.
