Method for controlling traffic signal lights

Abstract

The invention relates to a method for controlling traffic signal lights, wherein an intersection is provided with the traffic signal lights for controlling the travel of vehicles entering roads, and a central control system for controlling the display state of each traffic signal light; the traffic signal lights correspond to the roads in a one to one mode and display the conditions and travel directions of vehicles in the road; and the central control system determines the travel condition and the travel direction of each driveway according to the actual condition of the road. By adopting the method, the travel direction and the green light time of each driveway at an entering intersection can be controlled automatically, and the traffic capacity of the intersection is effectively used by controlling both the traffic direction and the traffic flow so as to reduce road congestions.

Description

technical field [0001] The invention relates to a traffic signal lamp control method, which can flexibly arrange the driving flow of each direction and each lane, effectively utilize the traffic capacity of road crossings, and reduce road congestion. Background technique [0002] The existing traffic signal controllers all have the function of induction control. According to the traffic flow signal at the corresponding entrance detected by the vehicle detector (ground sense coil, video detector), the green light time of the current phase is adjusted in real time, so as to achieve the signal timing matching with the vehicle. The purpose of traffic flow matching, for example, if the vehicle detector detects that the traffic flow at the entrance of a certain intersection is larger than the traffic flow at other entrances, then the green light lighting time corresponding to the entrance will be extended. But along with the increase of urban motor vehicles, it is more common that...

Problems solved by technology

[0004] However, this control method controls the congested vehicles on the entry road section. Although the congestion at the intersection is all alleviated, the vehicles that are blocked on the entry road do not drive through the intersection, which still causes pressure on the traffic at the intersection. Under the current urban road conditions, there is often a phenomenon of overall congestion of the entire road from one intersection to another during peak hours. This method of limiting vehicles to the road cannot solve this problem well.
