Embodiment Construction
[0038] Embodiments of the present application are described below in conjunction with the accompanying drawings.
[0039] refer to figure 1 Shown is a schematic diagram of an application scenario of the embodiment of the present application.
[0040] Among them, the traffic control system (traffic control system, TCS) is used to control the traffic strategy of the intersection. The traffic control system can be managed by the road administration department or the traffic department. Usually, you can choose to configure a traffic control system at an intersection, or you can share a traffic control system with multiple adjacent intersections. The traffic control system can communicate with multiple servers. The server may provide route planning information to the traffic control system. The server here may be a car factory platform server, a shared vehicle platform server, or other operating platform servers, etc., which is not limited in this application.
[0041] In order...

A traffic control method and device, the method comprising: a first traffic control system receives at least one piece of traffic demand information, and calculates a first traffic demand amount according to the at least one traffic demand information, and the first traffic demand amount refers to The time period is the first time period and the number of vehicles passing the first intersection is the first movement direction, and according to the first traffic demand, it is determined that the first intersection is in the first time period and in the first movement direction total traffic demand. If the total traffic demand of the first intersection in the first time period and in the first direction of movement is greater than the saturation value corresponding to the first intersection in the first direction of movement, the first traffic control system determines that in the first time period and in the first movement direction A movement direction adopts the first congestion control strategy, and sends a first congestion control assistance request to the second traffic control system. Therefore, the above method can be used to alleviate the degree of congestion at the intersection.
Description
technical field [0001] The present application relates to the field of traffic technology and vehicle network, in particular to a traffic control method and device. Background technique [0002] Traffic congestion has become a key issue in current urban problems, among which intersections are the bottleneck of traffic congestion management. In order to alleviate the congestion at the intersection, a large number of traffic infrastructures are concentrated near the intersection, including traffic lights, cameras, geomagnetic coils, etc. However, relying solely on the construction of traffic infrastructure cannot effectively solve the problem of traffic congestion at intersections. [0003] Therefore, it is particularly important to provide effective traffic control schemes for intersections that may be congested in order to alleviate the degree of congestion at intersections. Contents of the invention [0004] Embodiments of the present application provide a traffic contr...
