The invention provides a vehicle queuing length detection method, device and equipment and a readable storage medium. The method comprises the steps of obtaining trajectory data of an intelligent vehicle and trajectory data of surrounding vehicles collected by the intelligent vehicle; performing noise reduction processing on the trajectory data of each vehicle to obtain reconstructed trajectory data of each vehicle; identifying key points of the reconstructed trajectory data of each vehicle, summarizing the key points belonging to the same aggregation wave or evanescent wave, and pairing the aggregation wave and the evanescent wave belonging to the same congestion to obtain a first aggregation wave and a first evanescent wave belonging to the same congestion, and obtaining the wave velocity of the first aggregation wave and the wave velocity of the first dissipation wave; and determining a linear equation of the first aggregation wave or the first evanescent wave based on the space-time position of the vehicle passing through the first aggregation wave or the first evanescent wave and the wave velocity of the first aggregation wave or the first evanescent wave, and further determining the queuing length. The queuing length detection accuracy can be improved, and the practicability is high.

    本发明提供了一种车辆排队长度检测方法、装置、设备及可读存储介质,所述方法包括获取智能车采集到的自身的轨迹数据和周围车辆的轨迹数据;对每辆车的轨迹数据进行降噪处理,得到每辆车重构后的轨迹数据;识别所述每辆车重构后的轨迹数据的关键点,对属于同一集结波或消散波的关键点进行归纳,并对属于同一拥堵的集结波和消散波进行配对,得到属于同一拥堵的第一集结波和第一消散波,进而得到第一集结波的波速和第一消散波的波速;基于经过第一集结波或第一消散波的车辆的时空位置和第一集结波或第一消散波的波速确定第一集结波或第一消散波的线性方程,进而确定排队长度。本发明可以提高排队长度检测准确度,实用性较强。
