Standard crossroad vehicle fast passing method and device, and equipment

Abstract

The invention discloses a standard crossroad vehicle fast passing method and device, and equipment. The standard crossroad vehicle fast passing method comprises the steps that system settings and variables (va, tr, dm, lc and Lw) are initialized, wherein va is the preset average speed of the vehicle passing through the intersection, tr is the reaction time of a vehicle driver, dm is the average distance of the vehicle, lc is the average length of a vehicle body, Lw is the length of a waiting area, the single maximum passing time Ti, m (i=1, 2, 3, 4, m is the preset first passing scheme and thepreset second passing scheme) of the four combined directions of the four intersections in the preset cycle is correspondingly calculated, the scheme with the least weighted sum of Ti, m is selected,the control scheme of traffic lights is determined, according to the determined control scheme, the traffic lights are controlled, the reasonable and optimal distribution of the permission of passingtime in a cycle can be achieved, thus the vehicle passing rate in the intersections is further increased, and the traffic conditions of the intersections are further improved.

Description

technical field [0001] The invention relates to the technical field of vehicles passing at crossroads, in particular to a method, device and equipment for quickly passing vehicles at standard crossroads. Background technique [0002] At intersections with complex flow of people and vehicles, in order to ensure traffic safety and order, traffic light control is generally provided. These measures have effectively improved traffic conditions and increased the passing rate of vehicles at intersections. However, the existing more and more serious problem is that with the rapid increase of the number of road vehicles, the passing rate of intersections has reached or is close to reaching saturation; It is difficult to pass through the intersection at one time, and even cause congestion. There are only four possible situations at an intersection: U-turn, left turn, straight ahead and right turn, and each car has only one possibility. The passing rate of vehicles at intersections ...

Problems solved by technology

[0009] In order to ensure traffic safety and order, the existing standard intersection vehicle passing scheme is generally equipped with traffic light control, which effectively improves the traffic conditions and improves the passing rate of vehicles at the intersection. The more and more serious problem is that with the sharp increase in the number of vehicles on the
