| 收费站通行能力的大小直接影响到高速公路交通流的运行状况。为调控主线流量可对收费站实施收费通道控制等策略。针对收费站控制建立了高速公路收费站管控模型，利用VISSIM软件对甬台温高速公路温州南收费站进行了仿真。仿真过程中设置了不控制通道数量和控制通道数量两个场景，研究了针对改进收费站管控模型的仿真建模方法，对检测器位置、基础流入量、期望路段交通密度等参数进行了设置。通过仿真输出两个场景的流量、速度、旅行时间、延误等指标。仿真结果表明，在拥堵交通流状态下，通过实施收费通道控制，通过收费站的车辆的匝道延误有所增加，但是车辆主线下游延误有所降低。从整体来看收费通道管控对改善收费站主线下游拥堵有一定的效果。 |

| The capacity of a toll station directly affects traffic operations on freeways. To control the traffic flow of main lines, entrance control strategies can be implemented at toll stations. Aiming at simulation of entrance control, this paper proposes a control model of freeway toll station, and uses VISSIM to simulate Wenzhou South toll station of the Yongtaiwen freeway. Two simulation scenarios are set up and compared. The simulation method for improving the toll control effect is studied. The parameters, such as detector locations, basic traffic flow and expected traffic density, are implemented in VISSIM. The simulation results show that, under the condition of congested traffic flow, the ramp delay of vehicles passing through toll increases, but the delay of downstream vehicles in the main line decreases. From the overall point of view, entrance control has a certain effect on reducing the congestion of the main line nearby a toll station. |
