| 摘 要： | 以4车道路段为研究对象,对施工区域影响分析的阈值进行了详细的研究.选择了4因素3水平的影响因素对阈值进行分析,使用正交试验构筑了试验组合,并使用VISSIM软件对各种试验进行了仿真分析,得出了施工区域影响车辆行驶的因素依次为封闭车道数、道路饱和度、大车率、施工道长度.考虑到封闭车道数和饱和度存在交互影响,对封闭车道数和饱和度使用交互分析,再次使用仿真软件构筑封闭车道为2条车道和3条车道,且分别提取饱和度渐变时车辆的延误值,得到了4条车道路段施工时的交通影响分析阈值.

| Abstract: | The paper studies the Four-lane’s traffic impacting analysis threshold when the road is working.Four factors and three levels are chosen based on the possible impacting factors.The orthogonal experiment is used to get the experiments’ combination;the VISSIM software is used to get the experiment scene.Based on the simulation model,the order of the factors impacting the traffic is closed lane number,the saturation,the bus ratio and the work zone length.For the interaction phenomenon of the closed lane number and the saturation,when there are two or three closed lanes,the simulation scene is made again and the saturation is increased gradually.Finally,the threshold is got. |
