The invention provides a method and system for identifying a transportation mode based on mobile phone signaling. The method and the system are realized based on mobile phone signaling data reported by a user. In the implementation process, firstly, an identifying model is trained based on sample data reported by the user, after a special travel mode is eliminated, model training based on an SVM binary classifier is carried out, multi-dimensional characteristics of age, gender, speed, instantaneous speed, average speed and moving distance are adopted for training, and the identifying degree and accuracy of the model are improved; then, on the basis of a prediction model, a mode of fusing special travel and an SVM model is adopted, feature extraction is carried out on the basis of actuallyreported signaling data, and a travel mode is identified; and finally, on the basis of a time sequence, OD chains of different travel modes are combined to form a complete traffic mode travel track segment.
