The Research Of Traffic Safety Evaluation System Based On Road Factors

The economic development and the social progress promote the rapid development of transportation in our country,but at the same time, the frequent occurrence of traffic accidents has brought great trouble to the society, which caused too many casualties and property losses. Therefore, some work is imperative which are research on the traffic safety situation scientifically, to analyze the causes of traffic accidents, to reduce traffic accidents and reduce the loss of traffic accidents.Road traffic system is composed of several aspects of people, vehicles, roads, traffic environment, and any factors are inseparable with traffic safety. In these factors, the road, as the basis of the road traffic system, has an important effect on traffic safety.Based on the research on the evaluation of traffic safety at home and abroad, combined with the traffic safety situation of China’s national conditions and the present stage, in-depth analysis of the macro and micro factors which hazard traffic safety, and specially study the traffic safety influence and potential security risks of some indexes that are geometric shapes, road longitudinal section and cross section, road conditions and traffic safety facilities etc. According to the AHP theory, based on the weight analysis of several indicators of road condition, the traffic safety evaluation index system based on road factors was constructed, and the traffic safety evaluation model was proposed based on the fuzzy evaluation principle. Combined with a case section of the 209 National Highway in Shanxi province, make the comprehensive evaluation system based on the analysis of traffic safety, according to the evaluation results, find out the main factors affecting the traffic safety, and put forward suggestions for improvement measures, provide the basis of traffic accident analysis for the safety management department, provide a reference for road design, operation and maintenance department.
