Abstract

The invention discloses a traffic signal control method and device. The processor in the device is configured to execute: in the to-be-identified area of ​​each road section, determine the road section to be adjusted and the intersection to be adjusted according to the vehicle space density and the average vehicle speed; Adjust the green light signal of the control direction to be adjusted according to the remaining green light duration of the control direction to be adjusted on the road section to be adjusted at the current moment; and determine the control interception time; The interception duration determines the green light duration adjustment ratio of the intersection to be adjusted and the green light duration adjustment ratio of each upstream target control intersection in the target-related intersection, and determines the green light duration of each downstream target-controlled intersection in the target-related control intersection according to the total control amount of the road section to be adjusted. Adjust the ratio; apply each green light duration adjustment ratio to adjust the green light duration at the corresponding intersection. Improve the timeliness of intersection overflow control and prevent congestion transfer.

Description

technical field [0001] The invention relates to the field of intelligent traffic signal control, in particular to a traffic signal control method and device. Background technique [0002] As the traffic becomes more and more developed, the number of private cars is increasing, and the traffic congestion caused by short-term gatherings will follow. At the intersection, the driving direction of each vehicle may or may change, which makes the intersection more prone to congestion, which is called intersection overflow. [0003] In the related art, the control of intersection overflow is usually controlled after the fact, that is, after the overflow occurs, the overflowed road sections and intersections are controlled. This leads to a deadlock at the intersection when the overflow is determined. In addition, congestion transfer may also occur, resulting in congestion on other road sections. SUMMARY OF THE INVENTION [0004] An exemplary embodiment of the present invention p...
