| 摘 要： | 通过海南省国道G224海榆中线交通事故特征的时空分布分析和事故形态分析,得到双车道公路事故与速度特征指标间的相关关系;在综合分析车速与事故方面已有研究成果的基础上,提出了大小型车速度离散率的概念;基于海榆中线3年的事故统计数据及多处事故路段的连续车速观测统计数据,建立了大小型车速度离散率与事故率的关系模型,据此给出了大小型车速度离散率表征的具体路段事故状况评价标准。结果表明:大小型车速度离散率与事故率之间存在相关性,其相关模型采用指数分布拟合更为合理。

| Abstract: | Through the analysis of spatial and temporal distribution and the morphological characteristics of traffic accidents of National Road G224 Haiyu middle line of Hainan Province, qualitative analysis of correlation between indicators for the two-lane highway accidents and speed characteristics was carried out.Based on the comprehensive analysis in terms of vehicle speed and accident research results,authors proposed the concept of large and small size vehicle speed discrete rates.Based on road accident statis... |
