Paper Title
Study of Automated Highway System-A Review

Abstract
The Automated Highway System (AHS) concept defines a new relationship between vehicles and the highway infrastructure. AHS refer to a set of designated lanes on a limited access roadway where specially equipped vehicles are operated under completely automatic control. AHS uses vehicle and highway control technologies that shift driving functions from the driver to the vehicle. Throttle, steering and braking are automatically controlled to provide safer and more convenient travel. AHS also uses communication, sensor and react to external infrastructure conditions. The vehicles and highway cooperate to coordinate vehicle movements, avoid obstacle and improve traffic flow, improving safety and reducing congestion.
