Yunnan Road Traffic Safety Evaluation Method

Automobiles, as a traffic tool, have affected everywhere deeply for people's life. Especially in the recent years, with the development of the living standards, increased traffic accidents, which have been a big threat to man's life and property, have gone along with rising automobiles' number, so the requirement to the road safety is gradually higher and higher. The road safety directly affects and restricts the development of the transport sector. To improve the road safe performance and reduce the traffic accidents, the corresponding evaluation should be made objectively first to the road safety, and then the disposal scheme should be worked out to improve the traffic environment and promote the road operation benefits. Because China is a large country, and the traffic status is various, different traffic evaluation indicator should be made for each region. The article tries to provide the systematical analysis to the road traffic safety evaluation in Yunnan province based on the road traffic accident indicator value: accidents number, vehicular deaths and property loss. On the base of it, the detailed traffic condition should be considered comprehensively, and be evaluated among the mentioned indicators reasonably. Evaluation should be started from three courses: spots, alignments and sections. The evaluation to the spot course is to compare the different spots on the same road. Through the comparison, multi-accidents on road can be determined and the new method can be raised by combining the shortcoming of the existing method. To determine the multi-accidents in the new method, do a specific research for the spot firstly, and on this basis, study the relations between spot and spot and do the judgment. As added in the spot self-information, the whole information has been increased in the judgment and so the result is more reasonable. The evaluation to the alignment is to compare the different roads in the same zone. Through the comparison of safety performance, the safety performance rank with different roads can be found. The article raises the evaluation indicator system and use gray multiple kinds analysis to determine the roads as several ranks, according each indicator to confirm the road in which rank, so as to evaluate the safety performance of each road. The evaluation for sections course is to compare the different zones in Yunnan province. Through the comparison of safety performance, the safety performance rank with different roads of each zone can be determined. The article raises the evaluation indicator system and use gray multiple kinds analysis to divide the zones as several ranks, according indicator to confirm the zone in which rank, so as to evaluate the safety performance of each zone. By evaluating the three courses' safety condition, the evaluation system for road traffic safety will be formed.
