[0052] The extraction method of residents' travel OD distribution based on fusion data; the steps are as follows:
[0053] A. Clean and preprocess the original mobile phone signaling data, remove the error data and ping-pong switching data in the original mobile phone signaling data, and form the required mobile phone signaling data;
[0054] B. Process the questionnaire-style residents’ travel survey data to obtain residents’ travel characteristic parameters, which at least include travel rate, travel distance, and travel time;
[0055] C. Using the characteristic parameters of residents’ travel, calibrate and check the residence time threshold in the mobile phone signaling data, and obtain the initial OD distribution matrix of residents’ travel;
[0056] D. Through statistical methods, the mobile phone signaling data is reasonably expanded, and the expansion rate is determined according to the sampling percentage of the residents' travel survey. The expansion rate is the rec...
