Method for sensing and evaluating traffic safety road conditions

Abstract

The invention provides a method for sensing and evaluating traffic safety road conditions. The method comprises the steps that monitoring data of the monitoring range of a laser radar system are acquired, the data comprise radar ranging data of a moving object in the monitoring range, the monitoring range covers a monitoring lane and part of adjacent lanes, and the moving speed of the moving object in the monitoring range and the distance between the moving object and a detection point are calculated according to the monitoring data; according to the moving speed and the distance, the danger degree of the moving object is analyzed to the detection point and setting an early warning level; and when the moving condition of the moving object triggers the early warning alarm of the corresponding grade, the alarm early warning of the corresponding grade is sent out. According to the method for sensing and evaluating the traffic safety road condition, the data of the monitored lane and partof the adjacent lanes are obtained, the linear distance can reach 200-300 m, enough time can be provided for workers to avoid when early warning occurs, and the safety is improved. And the situation awareness of the moving object of the adjacent lane can be analyzed, 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, in particular 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 ...
