V2V (Vehicle to Vehicle) is recently seen as a very promising technology to avoid accidents and to relieve traffic congestion in transportation. DSRC (Dedicated Short Range Communication) is the most polular communication technology that could be used in V2V system. To figure out what extent DSRC could support typical V2V applications, this paper proposed a performance evaluation method. Firstly, we use cellular automata model to generate the spatial distribution of the vehicles. Then we simulated the procedure of V2V message propagation both as physical and MAC layer of DSRC. Compared with most of the analysis model, hidden terminal issue was taken into consideration as well. Based on the vehicles distribution and the message propagation procedure, we conducted an application-oriented performance evaluation of DSRC based on a typical application, namely FCW (Forward Collision Warning). Simulation results show that communication performance could not meet the need of safety related application under some circumstances, promotions should be fulfilled to guarantee the reliability of V2V applications.
