摘　　要：为探明山区高速公路长大下坡路段交通事故影响因素并提出针对性预防措施,文中基于坡度严重程度评价体系(GSRS)对长大下坡安全问题进行研究。对山区高速公路长大下坡路段事故影响因素进行分析,选取有效评价指标,构建长大下坡路段安全性评价模型;运用河南省洛栾高速公路实际运行数据,以六轴货运车辆为研究对象,基于修正的GSRS构建山区高速公路长大下坡路段安全评价模型对长大下坡路段进行安全评价,并运用TruckSim仿真验证模型有效性。结果表明,所构建的安全评价模型能有效判断山区高速公路长大下坡路段的安全性,可为交管部门道路安全管理提供理论依据。In order to find out the influencing factors of traffic accidents in long and steep downhill section of mountain expressway and put forward preventive measures,the safety problems based on GSRS are studied.Firstly,the influencing factors of accidents in long and steep downhill section of mountainous expressway are analyzed,and effective evaluation indexes are selected.Then,the GSRS model is modified to build the safety evaluation model of long and steep downhill road.Finally,using the actual operation data of Luoluan Expressway in Henan Province,taking 6-axis freight vehicles as the research object,the safety evaluation of long and steep downhill section is carried out based on the modified GSRS model,and the simulation is verified by using Trucksim.The results show that the safety evaluation model can effectively judge the safety of long downhill section of mountainous expressway,and provide theoretical guidance for traffic management department.
