The embodiment of the invention discloses a traffic flow estimation method and device, electronic equipment and a storage medium. The method comprises the following steps: acquiring trajectory data of N networked vehicles at an intersection in a current traffic signal period, and reconstructing an intersection shock wave according to the trajectory data of the N networked vehicles to obtain a maximum possible queuing length of the intersection; calculating a probability compensation value based on the maximum possible queuing length and the distance from the parking point of the last networked vehicle in the N networked vehicles to the intersection parking line; estimating the queuing length of the intersection based on the probability compensation value and the distance from the parking point of the last networked vehicle in the N networked vehicles to the parking line of the intersection; and performing estimation processing based on the queuing length of the intersection and the time when the N networked vehicles arrive at the stop line of the intersection to obtain the periodic traffic flow of the intersection in the current traffic signal period.
本申请实施例公开了一种交通流量估计方法、装置、电子设备及存储介质。其中方法包括:获取在当前交通信号周期内交叉口的N个联网车辆的轨迹数据,并根据N个联网车辆的轨迹数据对交叉口冲击波进行重构,得到交叉口的最大可能排队长度;基于最大可能排队长度和N个联网车辆中最后一个联网车辆的停车点到交叉口停车线的距离计算概率补偿值;基于概率补偿值和N个联网车辆中最后一个联网车辆的停车点到交叉口停车线的距离,估计交叉口的排队长度;基于交叉口的排队长度和N个联网车辆到达交叉口停车线的时间进行估计处理,得到交叉口在当前交通信号周期内的周期交通流量。
