交通事故多发点(段)占道路长度的比例非常少,但集中了较大部分的道路交通事故,严重降低了道路的服务质量,造成巨大的人身伤害和财产损失,具有非常大的危害性。运用合理的鉴别方法排查事故多发点(段),分析事故多发原因,从而提出相应的改善措施是提高道路安全性既科学又有效的办法。当量总事故率法是建立于事故率法和当量总事故次数法的基础上,集两者之优点的方法。该方法充分考虑道路长度、交通量及交通事故的危险程度,有针对性地鉴别事故多发点(段),并确定哪些事故多发点(段)需要优先整治。
There are very few traffic accident points (roads) in the length of the road, but a large part of road traffic accidents have been concentrated, seriously deteriorating the service quality of the road, causing great personal injury and property damage, which is very harmful. It is a scientific and effective way to improve the safety of roads by using reasonable identification methods to investigate the accident points (segments) and analyze the causes of accidents. Equivalent total accident rate method is based on the accident rate method and the equivalent number of total accidents on the basis of the method of combining the advantages of the two. The method takes full account of road length, traffic volume and the degree of danger of traffic accidents, and identifies the accident points (segments) in a targeted manner, and determines which accidents require frequent prioritization.
