Pedestrian crosswalk prewarning implementation method and prewarning system

Abstract

The invention relates to the field of road traffic security and discloses a pedestrian crosswalk prewarning implementation method and a prewarning system. The design idea of the pedestrian crosswalk prewarning implementation method is as follows: when a pedestrian passing through a pedestrian crosswalk is detected in a pedestrian detection area, an intelligent road sign embedded in the road automatically becomes flash yellow, and meanwhile, a high-brightness sign displays a text indicator, thereby reminding an automobile driver to watch for the pedestrian and taking deceleration measures in advance.

Description

technical field [0001] This application relates to the field of road traffic safety. Background technique [0002] Pedestrian crossings are high-incidence areas of traffic accidents at unsignalized intersections and road sections, especially at night and under conditions of poor visibility. It is difficult for motor vehicle drivers to see clearly the pedestrian crossing lines and pedestrians crossing the street, and cannot take timely deceleration measures, so it is easy to cause serious safety hazards. [0003] In order to solve the problem of frequent pedestrian crossing traffic accidents, the prior art mainly considers the following aspects: [0004] One is to draw white markings with a high reflective coefficient on the road surface, but the effect is not obvious under poor visibility conditions, and it is difficult to play an early warning role after the markings are damaged; [0005] The second is to set up street lights at pedestrian crossings to remind motor vehicl...
