摘要: 双向双车道施工封闭段易形成道路瓶颈,降低施工区通行能力。为保障施工区行车安全高效,增设信号控制,建立适用于双向交替通行的信号控制模型,借助Vissim软件建立仿真模型,运用控制变量法改变各仿真参数,通过对比分析得出施工段车速、到达交通量对道路运行情况的影响及规律。仿真结果表明,短距离和长距离养护,大车混入率分别在0.2和0.3左右对施工封闭段的交通流影响效应较大,且小于0.2和0.3时大车效应较为显著。

Abstract: The construction area of the two-lane roads can form the road bottlenecks easily, leading to the capacity of the road reducing. Aiming to keep the vehicle passing the construction area safely and efficiently, we added the strategy of signal control in the construction area. We built a suitable signal control model for the construction area of the two-lane road. By using the simulation software of Vissim, we established the related simulation models. By using the control variable method to change the simulation parameters and by changing the arrival traffic and speed, we got the influences and rules to the transportation performance. When the road maintenance is in a short-distance and the mix rate of large vehicle is at about 0.2, it has larger influence in traffic flow to the construction area of the road and the state of traffic flow is instability; when the mix rate of large vehicle is less than 0.2, the cart effect is more significant.

Key words: traffic engineering, two-lane road, signal control of two-lane road, simulation of Vissim
