Auxiliary lamp control method of traffic main and auxiliary lamp signal system

Abstract

An auxiliary lamp control method of a traffic main and auxiliary lamp signal system includes the following steps of: (1) judging whether a pedestrian street crossing request signal Q exists, if exists, entering (2), and if not, entering (3); (2) executing a first mode: if a red light of a pedestrian street crossing auxiliary signal lamp is turned on, accepting the pedestrian street crossing request Q that is executed after delay time T, and then judging the pedestrian street crossing auxiliary signal lamp, if the green light is turned on, rejecting the pedestrian street crossing request Q, if the red light is truned on, then setting the yellow light of an auxiliary signal lamp of motor vehicles to be turned on, and setting the turn-on time of the yellow light as Tyel; after counting down the turn-on time Tyel of the yellow light, setting the red light of the auxiliary signal lamp of motor vehicles to be truned on, the green light of the pedestrian street crossing auxiliary signal lamp to be truned on and the turn-on time of the green light as Tpass; after counting down the turn-on time Tpass of the green light, entering step (1); and (3) executing a second mode: setting the green light of the auxiliary signal lamp of motor vehicles to be turned on always. The control method can keep a balance between the pedestrian street crossing request and vehicle passing efficiency.

Description

technical field [0001] The invention relates to a method for controlling auxiliary lights of a traffic main and auxiliary light signal system. Background technique [0002] With the improvement of urban road construction planning and construction level, and the acceleration of people's life rhythm, the pedestrian crossing passages at the main intersections of urban roads can no longer meet the needs of pedestrians. The "people-oriented" concept of urban road design and planning has become a development trend. Setting up pedestrian crossing passages in between is an important embodiment of this concept. [0003] Pedestrian crossing passages mainly adopt three forms: pedestrian crossing (the "pedestrian crossing" mentioned below refers to the pedestrian crossing passage added between two main intersections to meet the needs of pedestrians crossing the street), underground passages and overpasses. The latter two forms are the most suitable. A thorough separation of pedestrian...

Problems solved by technology

[0010] In order to overcome the shortcomings of the existing main and auxiliary light signal control methods at intersections that cannot take into account pedestrian crossing requests and vehicle traffic efficiency, the present invention provides a traffic main and auxiliary light signal system that can balance pedestrian crossing requests and vehicle traffic efficiency. light control method
