Signal Timing Method and Terminal Based on Queue Length

Abstract

The present invention is applicable to the technical field of traffic control, and provides a signal timing method and terminal based on queuing length, including: obtaining the first number of vehicles passing through the intersection corresponding to the preset road section within a preset time period, that is, The number of all preset vehicles carrying GPS equipment passing through the intersection within the preset time period; the second vehicle number passing through the intersection within the preset time period is obtained according to the detection device, that is, the number of vehicles passing through the intersection within the preset time period The number of all vehicles; according to the first number of vehicles and the second number of vehicles, calculate the proportion of preset vehicles; according to the position information reported by the preset vehicles, calculate the first queue length of the preset road section; The first queue length is corrected to obtain the second queue length; according to the second queue length and the traffic capacity of the intersection, the signal period of the intersection is determined. The invention can improve the calculation accuracy of the queuing length, thereby optimizing the signal timing.

Description

technical field [0001] The invention belongs to the technical field of traffic control, and in particular relates to a signal timing method based on queue length and a terminal. Background technique [0002] The basic idea of ​​signal timing is to allocate the time resources of traffic intersections to the signal lights at each intersection according to the proportion of traffic flow in each direction, so as to direct the traffic at the intersection. Therefore, how to determine the optimal duration of the signal cycle is the key to signal timing. Generally, the optimal period should not be too long or too short. If the period is too long, the traffic capacity will not be significantly improved, but the delay of vehicles will be increased. bring inconvenience. According to the traffic flow of each intersection, geometric alignment, distribution of bus stops within the intersection range, area type and other related conditions, each intersection has a corresponding optimal c...
