| Automobiles have affected deeply to people's life for every walk being a traffic tool. Especially since the years, the living standard has been improved and automobiles are needed greatly and the requirement to the road safety is gradually high, and 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 shall be made objectively first to the road safety, then the disposal scheme shall be worked out to improve the traffic environment and promote the road transportation operation benefit. The article tries to provide the systematical analysis to the traffic safety evaluation, by setting up the road traffic evaluation system and method based on the three course: spots, alignments and sections, which study base will be the road traffic accident indicator value, i. e. numbers of accidents, numbers of the wounded and the dead and the property loss. Based on it is the comprehensive consideration to the detailed traffic condition, to be evaluated among the mentioned above indicators reasonably. The evaluation to the spot and course refers to the safety evaluation on different spots on the same alignment, as well the determination for multi-accidents on road, to raise the new method by combining the shortcoming of the existing method. The evaluation to the alignment refers to the safety evaluation to different road on the same zone, to compare with the safety performance for different roads in the same zone and to compare and identify the safety performance degradation with different roads, then to raise the evaluation indicators system and method. The evaluation for sections and courses refers to the road safety evaluation to the different zones in the big areas. By evaluating the three courses' safety condition, the system for road safety evaluation will be formed. For the roads at different zones in big area, the safety performance will be compared to determine the safety performance degradation and to raise the rational evaluation standard. |
