A highway traffic safety early warning system and method based on vehicle-road coordination

Abstract

The present invention belongs to the technical field of intelligent transportation, especially a highway traffic safety early warning system and method based on vehicle-road coordination. The following scheme is proposed, which includes a first bracket and a second bracket located on the ground. The first bracket The side close to the second support is fixedly connected to the same connecting plate, the bottom of the connecting plate is fixedly connected to the first scanner, and the sides close to each other of the first support and the second support are fixedly connected to the first scanner. Two scanners, one side of the first bracket is fixedly connected with a fixed seat, the invention has a simple structure, and the vehicle can be monitored in real time by installing the monitoring structure on the top of the vehicle, avoiding monitoring blind spots, resulting in information lag, and through the control center The analysis of the vehicle's three-dimensional shape data, self-weight, vehicle speed and road conditions can calculate the optimal driving speed of the vehicle, and can also give early warning to the vehicle in time.

Description

technical field [0001] The invention relates to the technical field of intelligent transportation, in particular to a highway traffic safety early warning system based on vehicle-road coordination. Background technique [0002] Accidents on expressways are often caused by traffic events. Traffic events can be divided into accidental events and frequent events. Construction, slippery roads, etc. According to the white paper on traffic accidents, the proportion of accidents caused by collisions with stationary vehicles and pedestrians on expressways is as high as 28%. If other event information is added, the proportion of expressway accidents caused by events will be even higher. Once a traffic accident occurs on the expressway, it is easy to induce secondary accidents. According to statistics, the casualties and property losses caused by the secondary accidents are more serious than those of the primary traffic accident. Only by quickly discovering traffic incidents and tak...

Problems solved by technology

[0003] In the prior art, most of the traffic incident detection methods are manual detection. The manual detection methods include full-time personnel inspection, manual monitoring of closed-circuit television, etc., but this method is not only time-consuming and laborious, but also the monitoring of closed-circuit television is placed at intervals, so it is impossible to detect The road conditions outside the range are detected, so there is information lag. In addition, driving suggestions cannot be given in time according to the current driving conditions of the vehicle. When a traffic accident occurs ahead, the driver cannot be warned in time, which may lead to serial rear-end collisions. , so it is not suitable for modern highway scene
