Intelligent transportation systems that designed to provide safer, more comfortable driving and traffic efficiency have developed rapidly in recent years. 802.11p and LTE-V are the major communications technologies used in V2X systems. Several studies have conducted extensive research and evaluation on the performance and application of 802.11p and LTE-V through modeling and simulation. However, V2X cloud collaboration systems based on LTE-V technology are rare. In most cases, V2X applications are safety-related, the performance of communication is very important. Especially in sonic emergencies, delay time may cause fatal accidents. Therefore, this paper proposes a collaborative cloud platform application architecture based on LIE-V technology. By real road environment tests on typical V2V and V2I scenes, we can see that the collaborative cloud platform system has excellent performance in assisting driver driving and road traffic control.
