In view of the increasing complexity of the current subway lines and the increasing population,the pressure on the carrying capacity of the subway has increased drastically,which has brought great difficulties to the operation and management of the subway. The method of forecasting short-term passenger flow of the subway is summarized in this paper.From the perspective of the current method of predicting short-term passenger flow of the subway,the relevant literatures on short-term prediction of subway passenger flow at home and abroad are reviewed and sorted out,and the related research methods are summarized.It is concluded that the current research methods can be divided into three categories,each with its own strengths,but most of them ignore the influence of weather,date and site,and do not separately predict the number of inbounds and outbounds.Although these methods have achieved good results,there are still some shortcomings,and there is still a lot of work to be done in related research. Therefore,relevant suggestions are put forward on this basis.
