Abstract: The present disclosure relates to an intelligent traffic cloud control system; by making full use of technologies such as cloud computing, edge computing, big data, and artificial intelligence, the present disclosure proposes a technical architecture of a cloud-edge-end cooperative road traffic cloud control platform, which can overcome the defects of the technical architecture of existing road traffic operation management and monitoring systems. The highway cloud control platform designed and developed based on this technical architecture can improve the operational efficiency of the road network under the premise of ensuring safety, so that highway users can obtain more timely, effective, and personalized driving and traveling assistance information; moreover, practical applications such as vehicle-road cooperative autonomous driving and other functions are supported.

Abstract: The present application provides an intelligent cloud traffic control system, which has a traffic data recalling and transmission architecture arranged hierarchically from bottom to top, and which includes: terminal devices, first-level cloud devices, second-level cloud devices, . . . ith-level cloud devices; wherein the ith-level cloud devices include a first cloud device, . . . a jth cloud device; the ith-level cloud devices further include: a first cache cloud, . . . a kth cache cloud arranged corresponding to the jth cloud device; wherein the jth cloud device stores a jth cloud device traffic data set, and the kth cache cloud stores a kth characteristic traffic data set; and data in the kth characteristic traffic data set has a higher priority of being recalled than data in the jth cloud device traffic data set. Therefore, the present application can preferentially recall traffic data in the cache cloud that has a batter correspondence to task, a smaller range and even a better data structure, thereby significantly improving the data recalling rate and retrieval response efficiency of cloud devices at the same level and even the entire intelligent cloud traffic control system.
