| 摘 要： | 通过整理G2京津塘高速公路3年（2007.3～2010.2）逐日逐时的百万车流量交通事故和交通流量及气象要素资料，并将百万车流量交通事故(交通事故与交通流量之商)与同步降水量进行日变化相关分析；结果表明：年平均百万车流量交通事故的日变化最高峰出现在05时，年平均高峰值高达234起•辆-1•10-6；年度、春季、夏季、秋季和冬季的平均百万车流量交通事故与同步降水量均呈正抛物线相关，即百万车流量交通事故随降水量的加大而增多；统计学检验（R＞Rα=0.01 和F＞Fα=0.01）效果很好。四个季节的百万车流量交通事故与降水量相关的系数高达0.7386～0.8635。这一分析事实为G2京津塘高速公路行车安全提供了客观的参考依据。

| Abstract: | The paper analyzes the data of Jingjintang expressway in G2 from March 2007 to February 2010,including the daily changes of the traffic accident on millions vehicles,traffic volume and meteorological elements.It further explores the relativity between traffic accident on millions vehicles(the number of traffic accidents/traffic volume) and the synchronous precipitation.The results show that the million traffic accidents peak of in one day appeared at 5 o'clock,and the average peak is up to 234 times in mill... |
