[0034] like figure 1As shown, the research area of this embodiment, that is, the location interval to be counted, is selected as Shenzhen City, and the records that do not meet the conditions are cleaned out by filtering the Shenzhen metro card data, and assuming that each pair of ODs travels according to the shortest path, and finds out that each pair of OD travels according to the shortest path Daily OD distribution, according to the statistics of the passenger flow of the subway section in the unit time window and the passenger flow of the subway in and out of the station, the Shenzhen subway passenger flow network is generated. The start and end times of the records are October 1, 2014 and December 31, 2014, respectively. In 2014, there were 118 subway stations and 252 sections in Shenzhen Metro. Select all passenger flows in October as historical data, select features through recursive feature elimination algorithm, and establish a regression prediction model. In Octob...
