The invention relates to a traffic jam control method and device and a computer readable storage medium, and belongs to the technical field of traffic. Comprising the following steps: planning n paths which do not pass through a target area for a traffic flow to be passed in the target area in a k time period, and carrying out random path distribution, so that the traffic flow to be passed in the target area in the k time period is 0; constructing a vehicle cumulative number flow conservation function of the target area in the k + 1 time period; based on the MFD curve and the MSD curve, calculating the maximum value of the cumulative number of vehicles in the target area in the k + 1 time period and the minimum value of the cumulative number of vehicles in the target area in the k + 1 time period; calculating an inflow traffic flow maximum value of the target area in the k period and an inflow traffic flow minimum value of the target area in the k period; and calculating the green light time of the signal lamp entering the target area in the k period, thereby controlling the traffic flow flowing into the target area in the k period. According to the method, boundary control and path induction are considered, traffic congestion is relieved, and the road network use efficiency and the regional traffic safety are improved.
本发明涉及一种交通拥堵控制方法、装置及计算机可读存储介质,属于交通技术领域。包括:为k时段目标区域的待穿过交通流规划n条不穿过目标区域的路径并进行随机路径分配,使得k时段目标区域的待穿过交通流为0;构建k+1时段目标区域的车辆累计数量流守恒函数;基于MFD曲线和MSD曲线计算k+1时段目标区域的车辆累计数量最大值和k+1时段目标区域的车辆累计数量最小值;计算k时段目标区域的流入交通流最大值和k时段目标区域的流入交通流最小值;计算k时段进入目标区域的信号灯的绿灯时间,从而控制k时段目标区域的流入交通流。本申请兼顾边界控制和路径诱导,缓解了交通拥堵,提高了路网使用效率以及区域交通安全性。
