Abstract

The invention relates to a traffic signal coordination control method at an arterial intersection based on non-equal period, and the invention relates to a traffic signal coordination control method. The invention aims to solve the problems of limited width of the existing green wave, low utilization rate of the coordinated phase green light, and many parking times of motor vehicles. The process is as follows: collect the entrance lane flow of each intersection; calculate the cycle duration of single-point control; divide the intersection into Type I and Type II; determine the value range of the public cycle; define the parameters of the arterial system; Constraints and the equivalent relationship between period and phase green light; Divide the intersection into different sets; Determine the start and end time of the green light; Determine the departure time of the leading vehicle and the trailing vehicle in coordinated traffic flow; Calculate the bandwidth of the three types of green waves; Construct a type I intersection When the straight line phase of the main line is not adjacent to the left turn of the intersecting road and when it is adjacent, the main line forms a green wave belt constraint; determine the objective function; determine the signal timing parameters of each intersection. The invention is used in the technical field of urban traffic control.

Description

technical field

[0001] The invention relates to a traffic signal coordination control method at an arterial intersection. The utility model belongs to the technical field of urban traffic control. Background technique

[0002] Arterial coordinated control is an important way of urban traffic control. Reasonable arterial coordination can greatly reduce traffic flow delays on arterial roads and improve the traffic efficiency of intersection groups. In the traditional arterial coordinated control method, all intersections have to execute the same cycle length, that is, the common cycle. It is generally applicable to adjacent intersections with relatively close flow rates and geometric structures. The common urban road network structure is generally to arrange several secondary arterial roads or branch roads between two main roads, so that the traffic flow can be reasonably collected and distributed. At this time, there are large differences in the geometric structure and tra...
