在分析国内外道路安全评价方法及相关指标的基础上,提出了基于驾驶仿真的道路线形安全评价指标。该指标不仅体现了驾驶员在不同道路交通条件下的行车特性对行车安全的影响,而且可直接与行车稳定性指标(如纵向滑移率、横向力系数等)建立关系,提高了评价指标的有效性。实例分析表明:该指标与行车安全具有良好的相关性,对评价道路线形的安全性具有重要的理论价值和实用价值。 Based on the analysis of domestic and international road safety evaluation methods and related indicators, a road safety evaluation index based on driving simulation is proposed. The index not only reflects the driver’s driving characteristics under different road traffic conditions on the traffic safety, but also directly with the driving stability indicators (such as longitudinal slip ratio, lateral force coefficient, etc.) to establish relations and improve the evaluation index Effectiveness. The case study shows that this index has good correlation with driving safety and has important theoretical value and practical value for evaluating the safety of road alignment.
