C-V2X (cellular vehicle-to-everything) is the international standards dominated by China’s enterprises for V2X wireless communications.Based on a brief review of C-V2X, it was indicated that C-V2X could provide capabilities such as low-latency and high-reliability for communications between vehicles and the surrounding traffic elements.C-V2X has demonstrated an obvious surpassing international technological trend and industrial competitions because of technical advantages.The related concepts of V2X, the relationship between 5G and C-V2X, the relationship between V2X and vehicle-infrastructure cooperation, the relationship between V2X and self-driving vehicles as well as the relationship between individual vehicle with intelligence and connected vehicles with cooperative intelligence, were clearly clarified.The insights about the development of C-V2X and intelligent connected vehicles (ICV) were presented.Facing the great strategic opportunities of global automobile industry revolution and China’s transportation industry reform, the innovative development mode of vehicle-infrastructure-cloud cooperation based on “5G+C-V2X” was proposed accordingly.Finally, the industrial progresses and problems were discussed with corresponding policy suggestions.

Key words: C-V2X, low-latency and high-reliability communication, 5G, intelligent connected vehicle, vehicle-infrastructure cooperation, I&C assistant driving, I&C self-driving, intelligent transportation
