Automated Vehicle-to-Vehicle Collision Avoidance at Intersections

Abstract

The authors present experimental results for an active control Intersection Collision Avoidance (ICA) system implemented on modified Lexus IS250 test vehicles. The system utilizes vehicle-to-vehicle (V2V) Dedicated Short-Range Communications (DSRC) to share safety critical state information, allowing for distributed implementation of the provably safe algorithms. Safety is achieved in potential collision scenarios by controlling the velocities of both vehicles with automatic brake and throttle commands. Automatic commands can never cause the violation of predefined upper and lower speed limits.
