Abstract

The embodiment of the invention discloses variable speed limit guiding method, device and system of roads, and a storage medium. The method comprises the steps of: firstly, obtaining traffic information in a collection area of a certain road section; next, judging whether traffic congestion occurs on the road section according to the traffic information, and if the traffic congestion occurs on theroad section, sending an instruction of executing a variable speed limit strategy to an upstream road section, if the traffic congestion does not occur on the road section, further checking whether the road section receives the instruction of executing the variable speed limit strategy sent by a downstream road section, if the instruction is received, indicating that the traffic congestion occurson the downstream road section, and immediately implementing the variable speed limit strategy. The variable speed limit strategy is mainly formulated based on the theory of traffic waves, which cantransfer congestion waves caused by the traffic congestion on the road section to the downstream as much as possible. In this way, the congestion can be controlled within a minimum range, and the adverse impact on large regional traffic can be reduced.

Description

technical field [0001] The present invention relates to the technical field of intelligent transportation, in particular to a method, equipment, system and storage medium for guidance of variable speed limit on roads. Background technique [0002] With the continuous development of electronic equipment, communication technology and the new generation of Internet and other technologies, intelligent transportation, especially the vehicle-road coordination system, has been vigorously promoted and widely used. The vehicle-road coordination system can realize dynamic real-time information interaction between vehicles and vehicles, and carry out vehicle active safety control and road collaborative management on the basis of full-time and spatial dynamic traffic information collection and fusion, which is helpful for realizing effective coordination of people, vehicles and roads and ensuring traffic Safety and improving traffic efficiency are of great significance. [0003] As we ...
