The invention discloses a ramp confluence control method and system for a smart train traffic system. The method comprises the following steps of 1, collecting motion information of main road vehiclesand ramp vehicles converging into a main road in a whole road section; 2, constructing a comprehensive optimization control model; 3, optimizing the motion states of the main road vehicles and the converging vehicles, and outputting expected accelerations of all the vehicles within a prediction time or a period of time; 4, taking the expected accelerations of all the main road vehicles output inthe step 3 as vehicle control instructions, and sending the vehicle control instructions to each vehicle; and 5, in the next control period, continuously executing the steps 1-4. According to the method, the vehicles converging into the main road can be freely adjusted according to the optimization target, higher efficiency is realized, and therefore the ramp traffic flow can converge into the main road with the traffic flow with higher density, and the ramp traffic flow is more suitable for the scene of the smart train.

    本发明公开了一种面向智慧车列交通系统的匝道合流控制方法及系统,该方法包括:步骤1,采集整个路段主路车辆和汇入主路的匝道车辆的运动信息;步骤2,构建综合优化控制模型;步骤3,优化主路车辆和汇入车辆的运动状态,并输出所有车辆在预测时间或一段时间内的期望加速度;步骤4,将步骤3输出所有主路车辆的期望加速度作为车辆控制指令,发送给各车辆;步骤5,在下一控制周期,继续执行步骤1~步骤4。本发明能够根据优化目标自由调整汇入主路的车辆,实现更高的效率,从而实现匝道交通流汇入密度更大交通流的主路,进而更适合智慧车列的场景。
