An analysis of the lane changing manoeuvre on roads : the contribution of inter-vehicle cooperation via communication

Many risky manoeuvres on roads integrate a lane change action. The synchronization of the involved cars is very important in such manoeuvres. The new generation of ADAS systems based on cooperation between vehicles can offer serious perspectives to such manoeuvres. The inter-vehicle cooperation is made possible thanks to the revolution in the wireless mobile ad hoc network. In this paper we analyze the lane change process and detect its risky aspects. Regarding this analysis we propose a cooperative system that aims to estimate the risk associated to lane changing and alert the driver when possible collision with other agents on the road is detected. An experimental study of this system is performed on our fleet of experimental communicating vehicles.
