山区公路爬坡车道的设置条件与方法研究

Study of Conditions & Methods for Setting-Up Climbing Lanes at Mountainous Road

山区公路长大纵坡路段是交通事故多发段,目前多集中于长大下坡的研究,却忽略了纵坡上坡路段行车安全研究。对于长大纵坡上坡路段,设置爬坡车道是降低事故率的有效途径之一,通过对上坡路段车辆运行现状分析,并参考国内外有关爬坡车道的研究成果,提出山区公路爬坡车道的设置条件和方法。

Serious accidents have continuously happened at long and large longitudinal ramp section of the mountain- ous road since recent years.Current study concentrates on the long and large downhill of the mountainous road but neglects driving safety at upwards-hill section at longitudinal ramp of it.For upwards-hill section at long and large longitudinal ramp,it is an efficient method to add a climbing lane to reduce accidents.Based on the analysis of vehicle driving at upwards-hill section and reference to home and abroad fruits of research,the con- dition and method for setting-up climbing lane at mountainous road are put forward.
