Rail passenger flow whole-course OD extraction method and system based on mobile phone signaling data

The invention relates to a rail passenger flow whole-course OD extraction method and system based on mobile phone signaling data. The method comprises the following steps: preprocessing the mobile phone signaling data; according to the preprocessed mobile phone signaling data, in combination with spatial geographic position data of network distribution of the mobile base station, obtaining time spatial feature data of movement and staying of the user; analyzing the travel condition of the user by using the time and space characteristic data of movement and staying of the user; and according to the travel condition, determining whole-course OD travel chain data of a starting point, a station entering point, a transfer point, a station exiting point and a destination of the user track travel. According to the method and the device, the position of the user at the moment of the signaling event is spatialized and quantified through association and matching of the signaling data and the position information of the
