V2V Test Scenario-Study on Intersection Collision Warning

The complex traffic environment of the intersection region makes traffic accidents occur frequently in this section. Intelligent network vehicles can give early warning of possible dangers through communication between vehicles and other traffic participants, so as to reduce the occurrence of traffic accidents. At present, many automobile enterprises are studying the landing application of vehicle to everything (V2X). This paper focuses on the application requirements of intersection collision warning (ICW) to V2X. Testing is an integral part of vehicle internet and can ensure safe and effective use of vehicle internet.In this paper, we describe in detail the testing process and results of communications performance of vehicle-to-vehicle (V2V) at an obstructed intersection in a closed test field where there are a lot of cars as a background. In addition, we have proposed a message forwarding mechanism based on vehicle to vehicle to infrastructure to vehicle (V2I2V), and the test results show that V2I2V performs better than V2V at an intersection with obstacles.
