The invention relates to a regional passenger flow prediction system and method, which are used for solving the problem that the implicit relationship of passenger flow information is difficult to comprehensively excavate in the prior art. According to the scheme, the method comprises the following steps: based on a block connection graph A and a historical passenger flow sequence Xinput, obtaining passenger flow change space correlation features, and predicting future passenger flow Y1 of each block; based on the historical passenger flow information Xinput and the corresponding time information Tx, obtaining the correlation characteristics between the passenger flow change time dependency relationship and the passenger flow information, and predicting the future passenger flow Y2 of each block; based on the historical passenger flow information Xinput and the corresponding time information Tx, a periodic change rule of the passenger flow information is obtained, and the future passenger flow Y3 of each block is predicted; fusing and recombining the passenger flow information Xinput based on the future passenger flow Y1, the future passenger flow Y2 and the future passenger flow Y3 to obtain Xrec; and predicting final passenger flow information of each block based on the recombination information Xrec and the corresponding time information Trec. Passenger flow information is enriched through prediction results with different emphasis, and the passenger flow information prediction accuracy is improved.
本案涉及一种区域型客流预测系统及方法,用于解决现有技术难以全面挖掘客流信息隐含关系的问题。本方案如下:基于区块连接图A和历史客流量序列Xinput,获取客流变化空间关联特征,预测各区块未来客流量Y1;基于历史客流信息Xinput和对应时间信息Tx,获取客流变化时间依赖关系和客流信息之间的关联特征,预测各区块未来客流量Y2;基于历史客流信息Xinput和对应时间信息Tx,获取客流信息的周期性变化规律,预测各区块未来客流量Y3;将客流信息Xinput、基于未来客流量Y1、未来客流量Y2、未来客流量Y3,进行融合重组得到Xrec;基于重组信息Xrec和对应的时间信息Trec,预测各区块最终客流信息。通过不同侧重点的预测结果丰富客流信息,提高客流信息预测准确度。
