Architecture Design of Vehicle-Road Collaborative Cloud Control Platform for Expressway Operation Management Unit

With the development of autonomous driving technology, China, based on its national conditions and existing advantages, has clarified the technological development path of Vehicle-to-Infrastructure cooperation system to realize a series of high-end auton omous driving functions such as network-wide dispatching and beyond visual range perception. Compared with the design of the existing cloud control platform, this article clarifies that the expressway operation management unit is the service object. The functional architecture and technical architecture of the cloud control platform are derived through the combing of car-road collaborative application scenarios. Various data resource items are refined, the driving speed threshold is clearly suggested, and the key control data items and equipment collaborative control party are listed according to the traffic flow merging in the ramp to improve road management and control capabilities to achieve the goals of safety, convenience, efficiency, greenness and economy.
