The invention discloses a ramp confluence control method for an urban expressway. The ramp confluence control method comprises the following steps: 1, collecting related motion state information of vehicles on a main road section of the whole expressway and afflux vehicles; 2, constructing a ramp confluence optimization control model; 3, optimizing the motion states of the vehicles on the main road and the afflux vehicles; 4, sending an optimized vehicle control instruction to each vehicle, and executing the control instruction by each vehicle; and 5, in the next control period, returning to continuously execute the steps 1-4. According to the ramp confluence control method for the urban expressway, unnecessary acceleration and deceleration of the main lane and ramp confluence vehicles areavoided, and the safety, economy and efficiency of diversion and confluence are effectively improved.

    本发明公开了一种面向城市快速路的匝道合流控制方法,包括如下步骤:步骤1,收集整个快速路主路段车辆以及汇入车辆的相关运动状态信息;步骤2,构建匝道合流优化控制模型;步骤3,优化主路车辆以及汇入车辆的运动状态;步骤4,将优化的车辆控制指令发送给各车辆,各车辆执行控制指令;步骤5,在下一控制周期,返回继续执行1~4的步骤。本发明的面向城市快速路的匝道合流控制方法,避免了主车道以及匝道合流车辆不必要的加减速,有效地提高了分合流安全性、经济性和效率。
