Abstract

The present application provides a method for perception assessment of traffic safety and road conditions, including: acquiring image data within the monitoring range; acquiring radar ranging data of objects within the same monitoring range as the image data from the lidar system, and the monitoring data includes image data and Radar ranging data, the monitoring range covers the monitoring lane and some adjacent lanes; according to the moving speed and distance, analyze the degree of danger caused by the moving object to the detection point and set the warning level; when the moving object moves, the corresponding level of warning is triggered When an alarm is issued, an alarm warning of the corresponding level is issued. The method for perception assessment of traffic safety and road conditions obtains data from the monitoring lane and some adjacent lanes, and the straight-line distance can reach 200-300 meters, which can provide enough time for staff to avoid when an early warning occurs and improve safety. And it can analyze the situation awareness of moving objects in adjacent lanes, the analysis data is complete, and the reliability is higher.

Description

technical field [0001] The embodiments of the present application relate to the technical field of traffic safety, specifically to the field of safety early warning, and in particular to a method for perception and evaluation of traffic safety and road conditions. Background technique [0002] During the construction and maintenance of traffic roads, such as road surface repair, traffic facility maintenance, faulty vehicle handling, etc., because the speed of passing vehicles is generally very fast (greater than 80 kilometers per hour or 25 meters per second), in order to strengthen the personal safety of operators For safety and security, the warning area should generally be set to more than 200 meters in order to ensure sufficient warning and avoidance time (5-8 seconds) for traffic engineering construction personnel. In the past, the traditional practice was to deploy ice cream cones by traffic safety officers. Ice cream cones with a length of more than 200-300 meters wer...
