Design of Cooperative Driving System Based on VANET

The rapid development of automobile industry has brought great convenience to people’s travel, but the increase of vehicles also brings a series of environmental problems and traffic problems, so this paper designs a cooperative driving system based on vehicular ad hoc network (VANET). As a product of the integration of communication industry and automobile industry, VANET can provide drivers with the perception ability beyond visual range, thus giving drivers more reaction time and reducing the probability of traffic accidents. In addition, in some specific environment, the system can achieve a certain degree of automatic driving, reduce the driver’s fatigue, but also reduce fuel consumption. Finally, this paper uses Simulation of Urban MObility (SUMO) to simulate the vehicle driving at the crossroads. According to the simulation results, under the action of the system, the vehicles can pass through the intersection safely and effectively.
