Abstract

The invention discloses a system and a method for controlling a ground-guidance type pedestrian street-crossing auxiliary signal in the field of traffic signals. A ground-guidance signal lamp group consists of two groups of side-group signal lamps, two groups of middle-group signal lamps and a group of center-group signal lamps, wherein the group of center-group signal lamps is arranged in the center of a pedestrian crosswalk; the two groups of side-group signal lamps are respectively arranged on the pedestrian crosswalk which corresponds to the center of an outer motorway; the two groups of middle-group signal lamps are respectively arranged on the pedestrian crosswalk which corresponds to the center of an inner motorway; each group of ground-guidance signal lamps is formed by connectinga row of small signal lamps in series; side faces A, B and C of each small signal lamp are luminous surfaces; the side faces A and B respectively face two ends of the pedestrian crosswalk; the side face C faces the entering direction of motor vehicles; and when pedestrians are endowed with a right of way and when the time of the right of way of the pedestrians is reduced, an intuitive passing signal prompt is provided for the pedestrians by controlling traffic lights on the side faces A, B and C, and the pedestrians can choose appropriate time and adopt a safe and effective behavior to cross the street.

Description

technical field

[0001] The invention relates to the field of traffic signals, in particular to a pedestrian crossing auxiliary signal control system and control method. Background technique

[0002] In order to ensure the safety of pedestrians crossing the street and regulate the behavior of pedestrians crossing the street and the passing behavior of motor vehicles, pedestrian crossings are basically set up at crossing places, and pedestrian crossing signal lights are also set up at major level crossings and road section crossings for better maintenance. Traffic order. However, in actual traffic, when pedestrians cross the street from the crosswalk to the middle of the road, the signal light changes into a right-of-way signal for motor vehicles, and motor vehicles begin to cross the crosswalk, so pedestrians can only wait awkwardly in the traffic flow for the next pass. Time to complete the crossing. In this way, not only the traffic efficiency of motor vehicles is affecte...

Embodiment Construction

[0013] The invention provides a ground-guided pedestrian crossing auxiliary signal system, which can be installed without changing the signal system of the existing intersection or crosswalk (hereinafter referred to as crosswalk for short). Such as figure 1 Shown: this system comprises crosswalk signal controller 10, pedestrian crosswalk signal lamp 11, ground guide signal controller 12 and ground guide signal lamp group 13. Wherein, pedestrian crossing signal control machine 10 is arranged on one end of pedestrian crossing, provides the control signal of various traffic lights including pedestrian crossing signal lamp 11; And according to the control signal that the crosswalk signal control machine 10 sends, provide the indication signal whether to allow passage at the crosswalk place to the pedestrian, red light is for prohibition, and green light is for permission.

[0014] Such as figure 2 , the ground guide signal controller 12 is also arranged at one end of the pedest...
