The invention discloses an urban expressway and entrance ramp control method. The method comprises the following steps: 1, setting a vehicle regulation and control system; 2, establishing a vehicle regulation and control model and storing the vehicle regulation and control model in a memory; 3, detecting the speed of the main road lane of the expressway and the traffic volume smooth value of the main road of the expressway; 4, determining the state of the main road of the expressway and matching the number of vehicles entering the main road of the expressway through the entrance ramp; and 5, selecting corresponding entrance ramp signal periods and traffic light display time according to different states of the main expressway. According to the method, the number of the vehicles on the main road of the expressway is reasonably adjusted according to the traffic state of the urban expressway and the requirements of the entrance ramps, so that the vehicles reach the maximum operation capacity but do not exceed the capacity of the vehicles, and the vehicles entering the main road on the entrance ramps are controlled according to the requirements of the main road of the expressway, so that the operation efficiency of the road network of the main road of the expressway is optimal.
本发明公开了一种城市快速路与入口匝道控制方法,包括步骤:一、设置车辆调控系统;二、建立车辆调控模型并存储在存储器中;三、检测快速路主路车道的速度和快速路主路交通量平滑值;四、确定快速路主路状态并匹配通过入口匝道进入快速路主路的车辆数;五、根据快速路主路的不同状态选择对应的入口匝道信号周期和红绿灯显示时间。本发明根据城市快速路的交通状态及入口匝道需求,合理调节快速路主路的车辆数,使其达到最大运行能力但又不超过自身的容量,根据快速路主线需要控制入口匝道上进入主线的车辆,从而使快速路主路路网的运行效率达到最佳。
