Research on cloud-network-edge-terminal architecture and service of vehicle-road collaboration

In this paper, the development trend of intelligent transport system(ITS) and the state art of vehicle-road collaboration are introduced. This paper focuses on the cloud-network-edge-terminal architecture of vehicle-road collaboration, includes central cloud, transport private network/telecommunication network, edge cloud, vehicle/road-side terminal and their collaborations.The open framework of information service capability of multi-source data fusion based on cloud-network-edge-terminal architecture for vehicle-road collaboration is presented. The specific functional requirements, API invocation methods and protocols are discussed in detail.
