Design and efficiency measurement of cooperative driver assistance system based on wireless communication devices

In this paper, we participate to the effort of investigating the use of the inter-vehicle communication in order to increase safety on the roads. In order to fill the gap between the standardization work and the proposed services, our work aims at designing cooperative applications using an existent wireless technology. In this paper, we describe the communication architecture deployed on board our fleet of intelligent vehicles and based on 802.11 g+ devices. Using this architecture, we will prove the feasibility of cooperative services. Thus, we choose to study two situations of conflict on roads: crossroads approaching and lane changing manœuvre. For both scenarios, we analyze the contribution of our system for risk assessment and collision avoidance.
