Traffic safety evaluation system and evaluation index calculation method thereof

Abstract

The invention provides a traffic safety evaluation system and an evaluation index calculation method thereof. The traffic safety evaluation system comprises 1, a traffic accident analysis module, 2, atraffic violation analysis module and 3, a traffic negative order analysis module, wherein the traffic accident analysis module calculates the number of per-capita traffic accidents and the proportion of fatal accidents through data recorded by the system; the traffic violation analysis module calculates the number of per-capita traffic violation and the proportion of important illegal events through the data recorded by the system; and the traffic negative order analysis module calculates the number of per-capita negative order events and the proportion of serious negative order events through the data recorded by the system. According to the traffic safety evaluation system, by taking the traffic accidents, traffic violation and traffic negative order events as observation objects, direct safety indicators such as happened accidents and violation are included, indirect safety indicators such as the negative order events are also included, comprehensive traffic safety evaluation is conducted by combing the multiple indicators of the three objects, the accuracy, rationality and comprehensiveness of traffic safety evaluation are improved, the defect that traffic safety is evaluatedfrom the single angle is overcome, and safety evaluation from the dimension of traffic hazards is complemented.

Description

technical field [0001] The invention relates to the technical field of traffic safety, in particular to a traffic safety evaluation system and an evaluation index calculation method thereof. Background technique [0002] At present, the evaluation of traffic safety in our country can be roughly divided into two categories: probability, mathematical statistics and intensity analysis. The probability mathematical statistics method is simple and easy in statistics, but it does not take into account the differences of different traffic conditions, which makes the evaluation results lack scientific and convincing. The intensity analysis method adds relative reference data to make the comparison between different road indicators more scientific and reasonable, but the accident itself is caused by many factors, and the reliability of a single index value as the evaluation basis is not high enough. Although the advantage of a single evaluation method is that the calculation is simp...

The strength analysis method adds relative reference data to make the comparison between different road indicators more scientific and reasonable, but the accident itself is caused by many factors, and the reliability of a single index value as the evaluation basis is not high enough

Although the advantage of a single evaluation method is that the calculation is simple, its disadvantage is that too few factors are considered, the accuracy of the calculation results is not high, and the evaluation content is mainly based on the accidents and violations that have occurred, and less from the perspective of traffic hazards.
