摘要
针对山区高速公路纵断面线形,分析路段通行能力差异性,从小客车驾驶员角度分析、计算能看到前车和前车尾灯时的最小纵坡视距,提出了以控制车流扰动过大和保证减速舒适性为目的的纵坡限速方法,并以此建立了基于驾驶行为和纵坡路段服务水平的纵坡限速分析模型.实例计算表明,通过该模型获得了邵怀高速公路设计车速为80 km/h路段的最佳限速值为100 km/h,从而对山区高速公路的路段最佳限速值的制定提供参考.
Focused on the mountainous area highway longitudinal profile line shape, the capacity of sections of highway difference is analyzed. In the view of car drivers, the minimum longitudinal grade stadia is analyed and calculated, a longitudinal grade limit method is proposed with the view of controling the traffic disturbance and guarantee comfort, and a longitudinal grade limit analysis model is established with this method, it＇s based on the driving behavior and longitudinal grade sections~ standard of service. Engineering examples indicate, through this model, ShaoHuai highway design speed of 80 km/h section of the best speed limit value with 100 km/h is obtained. Therefore,this provides a significant guidance for the mountainous area highway section with the best speed value.
