Problems solved by technology

However, in the process of highway construction, due to segmental construction and overlapping roads, the stake numbers will be discontinuous. Therefore, the traditional calculation and positioning method of stake numbers based on the starting point of the road and the length of the road has large errors, and the calculation workload Big

Abstract

The invention relates to the technical field of road traffic security management and particularly discloses an automatic traffic accident site road net matching verification method which comprises thefollowing steps: acquiring traffic accident attribute information; performing road name matching according to national road name standards, and acquiring a mapping relationship table of traffic management road codes, national road serial numbers and names; acquiring an accident longitude and latitude coordinate matched with pile numbers; verifying a spatial relationship of the accident longitudeand latitude coordinate and an administrative division region, and acquiring a first accident longitude and latitude coordinate qualified in verification; verifying whether a first accident longitudeand latitude coordinate site is accordant with an accident site description file or not, and acquiring a second accident longitude and latitude coordinate qualified in the verification; generating a traffic accident analysis geological data set. The invention further discloses an automatic traffic accident site road net matching verification system. By adopting the automatic traffic accident siteroad net matching verification method provided by the invention, accurate road traffic accident site road net matching verification can be achieved.

Description

technical field [0001] The invention relates to the technical field of highway traffic safety management, in particular to a method for automatic matching and verification of a road network at a traffic accident location and an automatic matching and verification system for a road network at a traffic accident location. Background technique [0002] Road traffic accident analysis is an important basic work in traffic management. Through the national public security traffic management comprehensive application platform (hereinafter referred to as the comprehensive application platform), all localities have realized the collection of accident location text information based on the basic information of the traffic management unified road code (hereinafter referred to as the traffic management road code). The comprehensive application platform resource library has gathered a large number of national traffic accident data. [0003] At present, highway traffic accident locations ...
