Embodiment Construction

[0027] The present invention will be further described below in conjunction with the accompanying drawings.

[0028] refer to Figure 1 ~ Figure 2 , an auxiliary light control method for a traffic main and auxiliary light signal system, the intersection signal main light 1 is set at the intersection, a pedestrian crossing 4 is added between two intersections, and a motor vehicle signal auxiliary light 3 is set on the pedestrian crossing , Pedestrian crossing signal auxiliary lamp 5 and pedestrian crossing request device, described auxiliary lamp control method comprises the following steps:

[0029] (1), judge whether there is a pedestrian crossing request signal Q, if there is, then proceed to step (2); if not, then proceed to step (3);

[0030] (2), execute the first mode, specifically:

[0031] (2.1), set the duration T of the green light in the pedestrian crossing signal auxiliary light pass , and the time period T for the auxiliary light controller to respond to pedest...

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...
