摘要
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 analysis of foreign road safety assessment ways and concerned norms, the paper puts forward linear safety assessment norms based on simulated driving, which not only indicate the effect of driver＇s driving characteristics under different traffic conditions on driving safety, but also directly establish the relationship with driving stability norms （for instance： vertical slip rate and lateral force coefficient etc） so as to increase the effectiveness of assessment norms. The analysis of practical case shows that the norms have good correlation with driving safety and important theoretic and practical value to assessment of linear road safety.
