The invention discloses a comprehensive transport system passenger transport mode sharing rate-distance transfer curve drawing method. The method includes the following steps that: a stratified random sampling survey method is adopted to obtain regional passenger travel information, a regional traffic travel database is constructed; according to a discrete selection behavior analysis method, a passenger transport mode selection model is constructed, and the parameters of the model are calibrated; the travel utility functions and selection probability expressions of each transport mode are determined according to the total structure of the regional transport modes, sample structures and parameter calibration results; and the selection probabilities of the transport modes under different transport distances are determined, and a regression analysis method is adopted to calibrate the selection probabilities of the transport modes, and a transport distance-based transport mode selection probability expression is determined. With the method of the invention adopted, the research gap of integrated transport system passenger transport mode sharing rate-distance transfer curve determination methods in China can be filled, and key theoretical support and technical support can be provided for comprehensive traffic planning software research and development. The method of the invention has a very broad application prospect.
