Method for automatically recording and positioning semantic expression information of traffic accident site

Abstract

The invention relates to a method for automatically recording and positioning semantic expression information of a traffic accident site. The method includes the following steps that firstly, when an accident data comprehensive management system receives input accident data, an accident site inputting and automatic positioning ActiveX is called; secondly, the accident site inputting and automatic positioning ActiveX requests road name data and a topological structure of a road net from a road name dictionary server; thirdly, the accident site inputting and automatic positioning ActiveX receives accident site information input by a user and automatic positioning is achieved according to the information input by the user; fourthly, whether positioning is right or not is judged, if yes, reporting is performed; if not, the user drags an accident site icon by hand to achieve manual positioning and then reporting is performed; fifthly, the accident site inputting and automatic positioning ActiveX transmits the accident site and the positioning information back to the accident data comprehensive management system, wherein the accident site and the positioning information are input by the user. Compared with the prior art, the method for automatically recording and positioning the semantic expression information of the traffic accident site has the advantages of improving the efficiency of data input, the correctness and the effectiveness of the accident site and the like. A basis is provided for correlation analysis of the accident site.

Description

technical field [0001] The invention relates to an automatic processing technology of traffic accident data, in particular to an automatic recording and positioning method of semantic expression information of traffic accident locations. Background technique [0002] After a road traffic accident occurs in a city, the traffic police need to go to the scene to investigate and deal with the accident. In the traffic accident certification issued by the traffic police, the traffic police need to record the location of the traffic accident and other relevant information. This information is not only used for accident liability Judgment and other legal affairs are also used in traffic safety management such as urban traffic accident black spot control and traffic safety early warning. As the situation of urban traffic safety becomes more and more severe, the governance and improvement of the traffic environment is imminent. [0003] Urban traffic accident black spot control, that...

Problems solved by technology

This patented technology depends on vehicle equipment and wireless communication network conditions, and cannot be universally applied, and cannot be applied to the daily work norms of traffic police

[0005] In the current traffic safety management system, the accident location is recorded as a long series of separate text records without format requirements and restrictions. The results of such text records are difficult to be split into valid and usable information, and it is difficult to verify afterwards the true exact location it describes

In Shanghai, the rules for the semantic expression of accident locations have been regulated many times, but before 2012, after complex semantic recognition and manual sorting of accident location records, the location rate of accident locations could only reach 58%, and the remaining location records were completely unavailable. position
