Intelligent warning system of pedestrian crossing and control method of intelligent warning system

Abstract

The invention discloses an intelligent warning system of pedestrian crossing and a control method of the intelligent warning system, and belongs to the technical field of intelligent traffic. The intelligent warning system comprises a controller, two groups of pedestrian identification cameras, two groups of vehicle speed detection cameras, two groups of laser emitters and two groups of projection warning lamps, wherein the pedestrian identification cameras are used for acquiring pedestrian image information of two pedestrian waiting areas, the vehicle speed detection cameras are used for acquiring vehicle image information and vehicle speed information of a vehicle driving towards the pedestrian crossing, the controller is used for performing risk estimation according to the received pedestrian image information, the vehicle image information and the vehicle speed information, so that the projection warning lamp is controlled not to work, project green light spot or project red light spot. By the intelligent warning system, the problems that pedestrian cannot be enabled to safely cross over the pedestrian crossing and the vehicle passing speed is easily affected by an existing pedestrian warning system are solved.

Description

technical field [0001] The invention relates to the technical field of intelligent transportation, in particular to an intelligent warning system for pedestrian crossings and a control method thereof. Background technique [0002] With the increase of the number of cars in our country and the rapid development of the road transportation industry, the number of road traffic accidents is also increasing. Most of the accidents occur at night when the lighting conditions are poor, and they often occur in low- and medium-speed urban pedestrian crossings. at the intersection. In addition, there are so many "head-down people" nowadays, they often fail to notice the traffic situation in time when they pass the crosswalk, which will greatly increase the possibility of accidents. [0003] The existing pedestrian crossing warning system is not perfect, and there are some deficiencies more or less, for example: (1) When pedestrians run through a red light, they cannot warn the driving ...

[0003] The existing pedestrian crossing warning system is not perfect, and there are some deficiencies more or less, for example: (1) When pedestrians run through a red light, they cannot warn the driving vehicles and remind them to pay attention to pedestrians; (3) When there are no pedestrians at the pedestrian crossing and the red light is on, the vehicles still need to wait to pass, which affects the speed of the vehicles. will cause traffic jams
