Method and equipment for identifying accident black points on traffic road

Abstract

The invention provides a method and equipment for identifying accident black points on a traffic road. According to the method, multiple pieces of traffic accident information of the traffic road areacquired, and the traffic accident information comprises the accident position information; statistics processing on the multiple pieces of traffic accident information is carried out according to theaccident position information to acquire one or more candidate black points and the accident statistics information on each candidate black point; and the accident black points on the traffic road are determined from the one or more candidate black points according to the accident statistics information. Compared with the prior art, three different dimensions, including point, road section and region, are fully considered when the accident black points are determined, so the accident black points can be more comprehensively, scientifically and effectively determined, an accident black point missing problem is effectively solved, moreover, through accident black point characteristic analysis, not only can the potential black points of the in-use road be pointed out, but also guidance values for in-building roads can be further realized.

Description

technical field [0001] The application relates to a method for identifying accident black spots in traffic roads, which belongs to the field of computers. Background technique [0002] With the increase of my country's per capita car ownership and road mileage, the problem of traffic safety is becoming more and more serious. At present, the research on accident black spots mostly starts from the data of traffic accidents, and according to the statistical results, the places with more accidents are the accident black spots. Since statistical laws are analyzed based on events that have already occurred, and its accuracy is affected by the number of samples, and traffic accidents are random events, road sections that have not had accidents for a long time but do have risk factors will be missed, leaving behind safety hazard. At the same time, for newly-built roads, or roads that have been in operation for a long time but have incomplete accident statistics, this method will h...

AI Technical Summary

Problems solved by technology

Since statistical laws are analyzed based on events that have already occurred, and its accuracy is affected by the number of samples, and traffic accidents are random events, road sections that have not had accidents for a long time but do have risk factors will be missed, leaving behind safety hazard

At the same time, for newly built roads, or roads that have been in operation for a long time but have incomplete accident statistics, this method will have the technical defect of inaccurate statistics, and the results obtained have little guiding value for other road safety analysis
