The invention discloses an intersection traffic flow microcosmic control method under an intelligent network connection condition. The intersection traffic flow microcosmic control method comprises the following steps: 1) dividing lanes into a CVT lane and an SCT lane; 2) when the vehicle drives to the variable speed control area, acquiring an initial state S0(v0, t0) of the vehicle; (3) accordingto the time when each vehicle arrives at the conflict point in the constant-speed control area and the occupied time, searching a space-time track capable of safely passing through for the vehicle from the travelable time interval of the vehicle flow, and obtaining the speed-time parameter S1(v1, t1) of the vehicle entering the constant-speed control area; 4) solving kinetic operating parametersof vehicles in the variable speed control area, wherein the vehicles in front of and behind the variable speed control area in the same direction should meet a certain relationship; 5) controlling thevehicles according to the motion parameters obtained in the step 3) and the step 4). According to the method, the motion process of the individual vehicles can be subjected to refined and systematicoverall planning, so that the overall operation efficiency of a traffic system is obviously improved.
本发明公开了一种智能网联条件下的交叉口交通流微观控制方法,包括步骤:1)将车道划分为CVT车道和SCT车道;2)当车辆驶达变速控制区时,获取其初始状态S(v,t);3)根据每辆车到达匀速控制区内冲突点的时间和占用的时间,从车流的可穿越时间间隙中为该车寻找一个能够安全通过的时空轨迹,获取车辆进入匀速控制区的速度—时间参数S(v,t);4)求取在变速控制区内车辆的动力学运行参数,且在变速控制区内同一方向前后车辆应满足一定的关系;5)根据步骤3)和步骤4)获取的运动参数对车辆进行控制。本发明能对个体车辆的运动过程进行精细化、系统性的统筹,从而使交通系统的整体运行效率得到明显提升。
