Yunnan Province, The Operation Of Road Safety Audit Of Accident Data Collection And Applied Research

To carried out road safety audit smoothly, not only set up a set of scientific appraisal system and an integrity safeguards system, but also needs the sufficient data; It's not imagine that the road safety audit has not the analysis of data. At present, the difficult of data acquisition and organization already has became primary cause which restrict road safety audit implement in our country. This paper is precisely focuses in establishing an management information system to be suitable for the road safety audit accident, to provide the detailed traffic accident information data for the operating road safety audit.First, thesis introduced elementary theory and the method of road safety audit on the operation stage; In view of the content and characteristic of road safety audit on the operation stage, summarized the data which needs.The, the pape has analyzed the accident information gathering method and the three application ways of road safety audit in the accident information: The traffic accident analyzes chart, the accident black spot and the path security appraisal. The paper solved some key question the traffic accident analyze chart and the accident black spot.The rationality of the traffic accident analyzes chart lie in the rationality the traffic accident drawing. The paper is deriving the predecessor's research results, classified the traffic accidensystem. This system emphasized emphatically the vehicles' path when accident occurs and can analyze the accident cause factor in detail. In this foundation, established the traffic accident schematic drawing that can apply in our country present situation. The traffic accident schematic drawing's establishment has solved the question which how in the chart to express each type accident in the traffic accident analyzes, to lay the good foundation for the analyze chart's establishment.The paper take SQL SERVER 2005 and .NET as a platform, has established the Yunnan Province road traffic safe audit accident information management system, has realized path accident information the inquiry, statistics and the analysis under each kind of condition. At the same time, the Rosa system can provide is audited the path accident information along the route, solved the traffic accident chart the accident position demarcation and the accident information determination. On the other hand, the Rosa system may inquire the accident information in the random length road section, user can conveniently statistical unit length's accident quantity, to determine the accident black spot. The Rosa system carries on the accident inquiry and the statistical analysis take the road section as the unit, compares to other accident statistics system that take the administrative area of jurisdiction as unit's, it is suitable to organization accident data for the road safety Audit.Finally, the paper used the Rosa System organization Kunshi highway's accident information, in this foundation, appraised on Kunshi highway's some accidents black spot, and has confirmed the Rosa system's reliability and the usability. Union the path video information and other material have carried on the preliminary safe analysis.
