Rail transit operation period division method and device and storage medium

The invention discloses a rail transit operation period division method and device based on an FCM clustering algorithm, and a storage medium, and the method comprises the steps: firstly sampling the historical data of urban rail transit in the line operation time, dividing the historical data according to a set time granularity, calculating a passenger flow analysis index after obtaining a target data set, and carrying out the calculation of the passenger flow analysis index; the method comprises the following steps of: selecting a passenger flow analysis index which greatly influences a passenger flow peak through screening, clustering by adopting an FCM fuzzy clustering algorithm, taking a defuzzification clustering result as a boundary point of operation time period division, and finally obtaining an optimal operation time period division scheme, so that an actual change rule of the passenger flow can be more effectively reflected. The problems that an existing operation period division method is high in
