| 摘 要： | 通过分析交通事故与几何线形的相关关系,提出了基于几何线形指标的山区高速公路路段交通安全评价方法。首先应用统计分析原理,建立了事故率与平、纵线形指标的关系模型,根据该模型确定具有不同线形条件的各类路段的基础事故率;然后利用各类路段的基础事故率,提出了单一线形的事故率系数及组合线形的综合事故率系数概念,并给出了系数计算公式和取值方法;最后利用综合事故率系数并基于统计分布原理,提出了基于几何线形指标的路段交通安全评价方法,并进行了案例分析。结果表明:该方法能够从几何线形指标的角度评估山区高速公路各路段的交通安全状况。 |

| Abstract: | By analyzing the relation between traffic accidents and geometric alignment,traffic safety evaluation method of the mountainous expressway section based on geometric alignment index was put forward.Firstly,applying the principle of statistical analysis,the relation models of horizontal and vertical alignment indexes and accident rate were built,so the basis accident rates of sections of different alignments were determined by the model.Then,using the basis accident rates with different sections,the concepts... |
