| 摘 要： | 为识别诊断道路潜在的危险路段,运用车辆动力学仿真模拟,从风险分析角度综合考虑道路几何线形、路面状况、路侧环境以及交通流组成等影响道路安全的因素.并通过事故树分析法综合多种事故类型,构建道路安全评价模型.用风险指数来综合反映道路上事故发生可能性和严重程度,从而用于定量地评价道路相对安全性.通过对实际工程设计阶段安全评价示例分析表明,所建立的道路安全评价模型能够定量计算,并直观显示行车风险沿道路全线分布情况,从而实现对道路潜在危险路段的识别和路段间相对安全性的比较.

| Abstract: | This paper studies a risk-based road safety evaluation model using vehicle dynamic simulation for the purpose of identifying hazard road locations.Road three-dimensional geometric alignment,pavement condition,roadside environment,and traffic flow component are involved in the model,and multi-types of accident are also taken into account using fault tree method.Road risk index is proposed as a surrogate for quantitatively evaluating the likelihood and severity of accident to measure the relative safety performance of the road.The results of an illustrative case study show that the proposed model is capable of computing risk distributing along the whole road,identifying and ranking hazard locations. |
