The embodiment of the invention discloses a vehicle trajectory data aggregation effect prediction method and device. The method comprises the following steps of acquiring vehicle parking waiting pointdata; dividing a predetermined area into a plurality of grids; counting the vehicle parking waiting point data of each grid in each second time period, and converting a counting result into a plurality of density matrixes; timing the plurality of density matrixes into a plurality of frames of video data; inputting the data into a preset aggregation effect prediction model for training; and according to the trained aggregation effect prediction model, predicting the parking waiting point data of the predetermined region in the target time period. According to the method, the problems that theexisting traffic flow prediction technology can only locally obtain the trend change of traffic flow increase or decrease, cannot globally perceive the process of traffic condition change in an urbanarea, cannot accurately predict the evolution trend of a future waiting aggregation effect and cannot deduce the formation mechanism of a hot area, are solved.

    本发明实施例公开了一种车辆轨迹数据聚集效应预测方法及装置,该方法包括获取车辆停等点数据;将预定区域划分为多个网格;统计每个第二时间段内位于每个网格的车辆停等点数据,并将统计后的结果转化为多个密度矩阵;将多个密度矩阵时序化为多帧视频数据;将数据输入预设的聚集效应预测模型进行训练;根据训练后的聚集效应预测模型预测预定区域在目标时间段的停等点数据。本发明解决现有的交通流预测技术只能局部获悉交通流增加或减少的趋势变化,不能全局感知城市区域内的交通状况变化的过程,不能准确地预测未来停等聚集效应的演变趋势,并推断热区的形成机理的问题。
