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 safety management, and specifically discloses a road network automatic matching verification method at a traffic accident site, which includes: obtaining traffic accident attribute information; performing road name matching according to the national road naming standard, and obtaining the traffic control road code The mapping relationship table with the national highway number and name; obtain the latitude and longitude coordinates of the accident matching the stake number; verify the spatial relationship between the latitude and longitude coordinates of the accident and the administrative division, and obtain the latitude and longitude coordinate point of the first accident that passed the verification; verify the first Whether the latitude and longitude coordinates of the accident are consistent with the description text of the accident location, and obtain the latitude and longitude coordinates of the second accident that have passed the verification; generate a geographic data set for traffic accident analysis. The invention also discloses a system for automatically matching and verifying road networks at traffic accident locations. The method for automatically matching and verifying the road network at the traffic accident site provided by the invention realizes the accurate road network matching verification at the road traffic accident site.

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 ...
