System and method for controlling ground-guidance type pedestrian street-crossing auxiliary signal

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...

AI Technical Summary

Problems solved by technology

[0003] The purpose of the present invention is to provide a ground-guided pedestrian crossing auxiliary signal control system and its control method, which are used to solve the problems of crossing difficulties and traffic safety when pedestrians cannot accurately estimate the crossing time when crossing the street. Before crossing the street and during crossing the street, you can more accurately evaluate your own street-crossing behavior, and then choose the right time to cross the street, and take safe and effective street-crossing behavior
