Passenger perception-based linked travel service bottleneck identification method

The invention relates to a passenger perception-based linked travel service bottleneck identification method, which comprises the following steps of: 1) data collection: collecting personal basic attribute data, travel feature data and linked travel service satisfaction data of linked travel passengers; (2) classifying the travel-in-travel passengers by adopting a hierarchical clustering method, and inferring the travel purpose of each type of passengers in combination with the personal basic attributes of each type of passengers and the statistical analysis result of travel feature data; (3) establishing a linked travel service bottleneck identification Rasch model and solving the linked travel service bottleneck identification Rasch model; and 4) checking the fitting effect of the model, and identifying the significant influence factor of each classification of passengers on the connected travel service satisfaction, namely the bottleneck factor.
