The invention discloses a signal intersection motor vehicle queuing vehicle track reconstruction method, which comprises the following steps: stipulating driving states of queuing vehicles on a signal trunk road, including cruising, deceleration, idling, acceleration and re-cruising in sequence, and enabling all the queuing vehicles to pass through a downstream real stop line in a traffic signal period; starting to dissipate the queuing vehicles at the speed of the traffic flow dissipation waves from the time when the red light ends and the green light starts in any traffic signal period; reconstructing the trajectory of the sample vehicle in any traffic signal period, including determining the traffic flow shock wave boundary in the traffic signal period according to the timestamp data information of the sample vehicle; and reconstructing the track of the non-sample vehicle in the traffic signal period. The data source required by the method is simple in structure and easy to obtain, can be directly suitable for various common traffic information acquisition technologies, and is low in calculation and solution difficulty; meanwhile, the method can meet the reconstruction research on the microscopic level of the vehicle track, and the reconstructed vehicle track is close to the real track on the ground.
本发明公开一种信号路口机动车排队车辆轨迹重构方法,包括:规定信号干道上排队车辆依次经历的驾驶状态包括巡航、减速、空转、加速、再巡航,并且所有排队车辆均在一个交通信号周期内通过下游真实停止线;从任一交通信号周期中红灯结束绿灯开始时刻,排队车辆以交通流消散波的速率开始消散;重构任一交通信号周期内样本车辆的轨迹,包括根据样本车辆时间戳数据信息确定该交通信号周期内的交通流冲击波边界;重构该交通信号周期内非样本车辆的轨迹。该方法所要求的数据源结构简单,易于获取,可直接适用于多种常见交通信息采集技术,且计算求解难度小;同时,该方法能够满足对车辆轨迹微观层面的重构研究,所重构的车辆轨迹接近于地面真实轨迹。
