Embodiment Construction

[0006] The first step is to move the position of the parking line back for a certain distance, and set the area between the new parking line and the original parking line as the acceleration area. In practical applications, the length of the acceleration zone must be determined according to the actual situation of the intersection, and different lengths can also be set for the acceleration zone of different driving lanes; the second step is to adjust the traffic light switching mode. From the original mode of transitioning to another set of green lights (green light, green flashing light, yellow light, and all red lights at the intersection) after completing a set of green lights, it is changed to start the second set of green lights at the same time before the end of the first set of green lights . The time for the overlap of two groups of green lights is determined on the one hand according to the time required for vehicles in the lane controlled by the second group of green...

Abstract

The invention discloses a planar intersection vehicle passing control method capable of improving the intersection passing efficiency. The method is characterized in that the position of a primary stop line is backward shifted with a certain distance to increase an acceleration region so that the starting acceleration process of a vehicle at the intersection is performed in the acceleration region in advance and the speed of the vehicle passing through the intersection is improved; and a part of green light permission time is overlapped, namely the next group of green lights is turned on when the previous group of green lights is not turned off so as to counteract the time consumed when the vehicle runs through the acceleration region and prolong the passing time of each group of green lights without increasing the cycle time of the traffic light.

Description

technical field [0001] The invention relates to a method for vehicle traffic control at a level intersection. Background technique [0002] At present, there are many methods for vehicle traffic control at level intersections, but none of them can solve the problem of low traffic efficiency caused by the slow speed of vehicles passing through the intersection. The main reason is that because the stop line is set close to the intersection, the vehicle is often in a low-speed driving state from starting to slowly accelerating at the intersection. Contents of the invention [0003] The purpose of the present invention is to provide a kind of traffic control method that can improve the traffic speed of the level crossing. The method can solve the problem of low traffic efficiency caused by the slow speed of vehicles passing through the intersection. [0004] The present invention is realized by adding an acceleration zone and partially overlapping the green light release tim...
