The invention provides an online car-hailing demand prediction method and device, equipment and a storage medium, and relates to the technical field of traffic prediction, and the method comprises the steps: obtaining online car-hailing demand time and road traffic data of an online car-hailing starting place and a destination in a preset time period, and carrying out the preprocessing, so as to construct a road traffic state matrix, global view division is carried out based on a preset time interval, and then processing is carried out by using a doliolaria algorithm to obtain a target process view state matrix; carrying out feature splicing on the two state matrixes to obtain local spatial feature information, inputting a pre-configured gating cyclic convolutional neural network model to obtain local spatial-temporal feature information, carrying out dimension reduction processing to obtain regional feature information, and carrying out dot product operation to obtain global spatial feature information; and the prediction result is obtained by inputting the time and the online car-hailing demand time into the converter model, and the prediction accuracy is improved due to consideration of multiple factors such as time, local and global spatial correlation and origin-destination demands.

    本申请提供一种网约车需求预测方法、装置、设备及存储介质,涉及交通预测技术领域,方法包括:获取网约车需求时间、预设时间段网约车起始地和目的地的道路交通数据,进行预处理,以构建道路交通状态矩阵,基于预定时间间隔进行全局视图划分,再利用樽海鞘算法进行处理,得到目标过程视图状态矩阵;将上述两种状态矩阵进行特征拼接,得到局部空间特征信息,以输入预配置的门控循环卷积神经网络模型,得到局部时空特征信息,进行降维处理,得到区域特征信息,经过点积运算,得到全局空间特征信息,并将其和网约车需求时间输入转换器模型,得到预测结果,由于考虑时间和局部、全局的空间相关性以及起讫需求等多种因素,提高预测的准确性。
