在公路设计阶段,通过安全评价(审计)可以有效提高公路的安全水平,可以达到减少交通事故、提高交通效率的目的。综述了在公路设计阶段安全评价中基于运行车速的评价方法、基于车辆稳定性的评价方法、基于道路几何特征的评价方法和基于驾驶人指标的评价方法等4个主要研究方向,阐述了当前公路设计安全评价中的一些研究重点,并展望了今后的发展趋势。
At the stage of highway design, the safety assessment (audit) can effectively improve the safety level of the highway and achieve the purpose of reducing traffic accidents and improving traffic efficiency. This paper summarizes four main research directions of the evaluation methods based on running speed in highway safety evaluation, such as the evaluation of vehicle stability, the evaluation method based on vehicle stability, the evaluation method based on road geometry and the evaluation method based on driver’s index. Some of the key points in the design of safety assessment and the future development trend are forecasted.
