摘 要：
通过对城市局部路段车道缩减现象的分析,得出缩减路段的道路参数、车辆行驶速度等因素对缩减路段的通行能力有一定影响。运用Vissim仿真软件对车道缩减路段进行微观仿真,研究其对道路缩减路段通行能力的影响。将车道缩减路段分成缩减前、缩减区、缩减后三个部分,对车辆行驶速度在40 km/h,50 km/h,60 km/h情况下分别进行微观仿真,记录缩减路段通行能力、车辆延误等参数,运用数据分析软件进行分析。仿真分析结果表明:当车辆行驶速度较低时,车道缩减前、后路段的长度变化对通行能力、车均延误影响不大;随着车辆行驶速度的提高,影响逐渐明显;当车道缩减前、后路段为30 m,缩减区路段为100~120 m,车辆平均行驶速度为60 km/h时,车道缩减路段的通行能力达到最优。

摘 要：
Based on analysis of the phenomenon of lane reduction in city roads, it is concluded that road parameters and vehicle speed in lane reduction areas have some influence on traffic capacity. Vissim simulation software is used to simulate lane reduction, and the simulation results are analyzed. The lane reduction area is divided into three parts: before reduction area, reduction area, after reduction area, and microcosmic simulation was carried out at 40 km/h, 50 km/h and 60 km/h respectively. After simulation, the parameters such as traffic capacity and vehicle delay are recorded, then the data analysis software is used to analyze. The simulation results show that when the vehicle travel speed is low, the front and rear sections of the reduction area have little effect on traffic capacity and vehicle delay. When the length of the front and rear sections of the reduction area is 30 m, the length of the reduction area is 100~120 m, and the average traveling speed of the vehicle is 60 km/h, the traffic capacity of the lane reduction area reaches the optimal situation.
