Implementation of Vehicle-Road-Cloud Integrated Systems in China

During the 21st Expert Meeting on Automated, Autonomous and Connected Vehicles (GRVA), held at the Palace of Nations in Geneva from January 20 to 24, 2025, experts from China presented the GRVA-21-48 document on the integrated systems of “Vehicle-Road-Cloud Integrated Systems” (VRCIS) tested and implemented in China – the Vehicle-Road-Cloud functionality provides benefits such as augmented perception and enables data sharing between different areas of traffic management in the city.

In January 2024, a pilot of the VRCIS application was launched in China. Cities involved in the project are required to adopt a unified system architecture, adhere to consistent standards, ensure interoperability of services, and maintain safety, security and reliability in all operations.

From January to October 2024, the 5G network deployment rate reached 14.9%, LTE-V2X deployment reached 2%. Many OEMs including FAW, SAIC, GAC, BAIC, Great Wall Motor, NIO, King Long, Audi, SAIC-GM have achieved mass production of 5G/LTE-V2X based V2V/V2I/V2N warning applications.

Examples of such implementation include traffic light information, which is widely used in vehicles and pilot cities. Large-scale implementations include traffic management, road accidents and collisions, V2V communication. Due to the low dependence on infrastructure, the above use cases are being discussed by OEMs and cities, and it is expected to be widely used in 2025.

By 2024, 20 cities in China have deployed a total of 3368 ADS vehicles, including: intelligent bus, robotaxi, delivery vehicle, AVP, etc. It is planned to deploy more automated and connected vehicles by 2026.
