基于失控车辆行驶特性的平行式避险车道研究

Research on Parallel Escape Lane Based on Driving Characteristics of Runaway Vehicles

为了解决分离式避险车道存在的安全问题,分析了境内外分离式避险车道存在的不足,基于失控车辆行驶特性对平行式避险车道平面设计、纵面设计、横断面设计和路床材料选择等进行分析和研究,并对平行式、分离式避险车道进行了对比分析。研究认为平行式避险车道以驾驶员自救为原则,在驾驶员认为车辆存在较大的失控风险或车辆已失控时驶入,在避险车道停驻或速度降低后,再驶入主线,设置条件更为灵活,易于救援,工程规模小,值得深入研究和推广。

In order to solve the safety problem of the separated escape lane,in the paper the shortcomings of the separated escape lane are analyzes.Based on the driving characteristics of out-ofcontrol vehicles,analysis and studies are carried out in terms of the parallel escape lane\plan and profile,cross-sectional design,and base course material selection.At the same time,the divided escape lane and parallel escape lane are compared and analyzed.The research results show that the parallel escape lane is based on the driver\s self-rescue principle.When the driver considers that the vehicle has a large risk of out of control or the vehicle has been out of control,the vehicle enters the carriageway after stops or reduces the speed on the escape lane.This mode is more flexible,easy to rescue,with small scale of works,which is worthy of in-depth study and promotion.
