摘　　要：为研究山区弯路驾驶员回避危险控制车速行为特性,以山区公路危险路段的驾驶员行车速度作为主要研究目标,将山区公路弯道路段入弯前车辆减速行为的观测和调查数据作为参考对象,建立了基于山区公路平曲线路段的驾驶员危险认知行为的行车速度控制模型,并利用实例对行车预测模型进行了对比验证。结果表明,所建减速控制模型可行、有效,能较好地模拟车辆经过限速标志或路面减速标识路段时的减速行为,为山区公路线形设计、行车安全性分析与评价,以及山区公路交通安全改善提供新的理论方法和指导依据。In order to study the speed control behavior characteristics of driver risk avoidance on curved highways in mountain area,the driving speed of vehicles on mountain highways is taken as the main study object.The observation and survey data on vehicles deceleration behaviors before they enter a curve on the curved sections of mountain highways are taken as the reference object to establish the drivers driving speed control model on the horizontal curve sections of mountain highways,and an example is used to conduct comparative validation on the driving deceleration model.The calculation results show that the deceleration control model established here is feasible and effective,can better simulate vehicles deceleration behaviors when they pass through speed limit signs or the sections with road surface deceleration signs and provides a new theoretical method and guiding basis for the line features design,traffic safety analysis and evaluation and traffic safety improvements of mountain highways.
