Variable lane control method based on vehicle-road cooperation

Abstract

The invention discloses a variable lane control method based on vehicle-road coordination, which comprises intersection signal control equipment, a vehicle-road coordination device is loaded in the intersection signal control equipment, and the vehicle-road coordination device loads communication and perception capabilities for a signal control machine by integrating a roadside communication device in the signal control equipment and integrating a vehicle-mounted device in a vehicle. According to the technical scheme, the method is characterized in that a specific implementation mode is as follows: a left-turn phase and a straight-going phase, the left-turn phase: L1-L2 is greater than 4, it is confirmed that a left-turn queue is relatively long, L2 is recorded, and a next acquisition period is entered; L1-L2 is less than or equal to 4, and the default mode of the variable lane is straight; when the straight-going phase L1-L2 is larger than 4, it is confirmed that the straight-going queue is long, and the default mode of the variable lane is straight going; L1-L2 < = 4, it is confirmed that the left turn queue is long, L2 is recorded, the next acquisition period is entered, and ifthe conditions 1 and 4 occur in the two acquisition periods and L2 is greater than a set threshold value, the variable lane is changed.

Description

technical field [0001] The invention relates to the field of traffic variable lanes, in particular to a vehicle-road coordination-based variable lane control method. Background technique [0002] In recent years, with the rapid growth of urban population and motor vehicle ownership, urban traffic problems have further aggravated. Intelligent traffic signal control can scientifically allocate traffic rights, improve traffic order, improve traffic capacity and traffic efficiency at road intersections, and reduce traffic delays. and waste of resources, improve the carrying capacity of regional and urban road networks, and effectively alleviate traffic congestion. [0003] Variable lanes are a very popular traffic control method in recent years. We know that the wider the road and the more lanes, the stronger the traffic capacity of the road. However, with the increase in car ownership, in many cases, the number of lanes designed for the original roads can no longer meet the tr...

Problems solved by technology

[0005] In order to overcome the deficiencies of the prior art, the object of the present invention is to provide a variable lane control method based on vehicle-road coordination, which solves the problem of separating the traffic flow data of left-turn and straight lanes by adopting a combination of phase release mode, corresponding to different The traffic demand of vehicles in different directions meets the key application requirements of variable lanes; through the application of traffic flow data based on the queue length and supplemented by the average speed of the lanes, the accuracy of variable lane control is ensured to solve the problems in the background technology that cannot be truly real-time. Grasp the traffic demand at intersections, so as to make the most accurate technical issues of lane attribute changes
