| 摘 要： | 针对国内道路交通事故资料调研困难的现状，采用常用的前／后分析法原理对同一条道路不同路段进行分析，这样利用较少的数据量也能发现与道路安全有关的规律。为此提出了针对两种不同情况的统计分析方法和相应的事故概率计算、对比和对比结果置信度检验的公式。应用此法重点对高速公路的线形指标与道路安全性的关系进行了分析。

| Abstract: | Considering the difficulty of collecting enormous data of traffic accidents,the analysis on the different sections of one road was carried out through applying the theory of before/after study.The regularity of road safety can be found out using the before/after study method with a relatively few data.In this paper,the method of statistic analysis especially about two kinds of different conditions was established.The calculation and comparison of accident probability and equations of reliability verification on the results of comparison were also developed.The relation between road alignment feature and road safety was investigated specially using the method. |
