As one of the key technologies of the new generation intelligent transportation system, the Internet of Vehicles can improve road traffic safety and efficiency. The promotion of vehicle networking applications is inseparable from the system's functional and performance testing. At present, the test evaluation methods can be divided into simulation and field test. However, most evaluation methods are communication-based, but the feasibility and reliability of the Internet of Vehicles application cannot be evaluated based solely on network metrics such as latency and packet loss rate. In this paper, to meet the application requirements of cooperative intelligent transportation system V2V communication, the urban and rural intersections, the fast straight lane car-following and car meeting scenarios are built. A modular test platform for intelligent network interconnected traffic applications is constructed, and a DSRC and LTE-V application-oriented performance test system and method is designed on the platform. Under these scenarios, we conduct experiments and design an evaluation index for DSRC and LTE-V security applications. The results show that LTE-V has a wider communication range than DSRC or more reliable performance in the same range in non-line-of-sight scenarios. In high-speed scenarios, DSRC has better performance in Doppler shifting against high-speed environments.
