The research on the factors affecting the convenience of urban integrated transportation transfer can provide scientific basis and guidance for urban transportation planning. Based on the comprehensive transportation theory and transfer convenience theory, the logic of the comprehensive transportation transfer system was sorted out, and the comprehensive transportation transfer system diagram was drawn. Then, from the two perspectives of the comprehensive transportation hub station and the transfer origin-destination(OD) pair of a single station, Pearson correlation analysis, geographic detector model and multiple linear regression model were used to study the factors affecting the convenience of integrated transportation transfer. The results show that the transfer convenience of a single hub station is mainly related to the location of the hub station. Geographical distance, travel mode and number of travel stations are the main factors of the shortest transfer time, and the number of travel stations is the most important factor. Geographical distance, shortest highway mileage, travel mode and number of travel stations are the main factors of the least transfer cost, among which the travel mode and number of travel stations are the most important factors.
