为了研究高速公路长大隧道内交通事故影响程度,文章以江西省第一长隧道九岭山隧道为研究对象,通过VISSIM交通仿真软件建立交通仿真模型,在设置不同等级的交通流量以及大货车交通比例的条件下,仿真获得高速公路长大隧道交通事故发生后车辆排队长度以及延误时间,用以分析高速公路隧道内交通事故对隧道通行能力的影响,以更大程度上实现高速公路隧道安全行车。
In order to study the impact of traffic accidents in the long tunnel of expressway, this paper takes the Jiulianshan Tunnel of the First Long Tunnel of Jiangxi Province as the research object and establishes the traffic simulation model by VISSIM traffic simulation software. After setting different levels of traffic flow and large truck traffic Ratio of the length of the highway tunnel traffic accident queue length and delay time to analyze the impact of highway traffic accidents on the tunnel capacity in order to achieve a greater degree of highway tunnel traffic safety .
