The invention discloses a station passenger flow volume trend prediction and statistical analyzing method, which comprises the following steps: S1) recalling the historical passenger flow volume data; S2) establishing the functional relationship between the arrival time of the passengers and the number of passengers into the station in an earliest allowable period, or rather, the passenger flow volume trend forecasting model; and S3) utilizing the model obtained from the step 2 to make predictions; and according to the prediction data, making statistics and analysis of the passenger flow volume; and generating visible display. According to the method proposed by the invention, it is possible to estimate the passenger flow volumes of various periods of a day in the future as well as the passenger flow volumes of various waiting rooms so that the station working staff could clearly know in which period, the passenger flow volumes reach their peak, and in which waiting room, the peak of passenger flow volumes might occur, therefore, providing effective basis to avoid and control the passenger flow volume peak, regulate the loading capacity of trains and make proper scheduling.
