Abstract: This paper analyzes the factors that influence the waitingposition selection behavior of urban rail-transit passengers from three aspects, passenger feature, platform characteristics, and train operation. A behavioral model for passenger waitingposition selection is constructed using Logit model. This model includes six influencing factors: congestion tolerance, queue length, full load ratio of train carriages, walking distance, field of vision, and travel purpose. The model parameters are calibrated using the data from questionnaire surveys. The results show that the waitingposition selection behavior differ among rail-transit passengers. Passengers with high congestion tolerance tend to choose a waiting position based on the combination of full load rate and queuing length, whereas passengers with a small field of vision prefer to choose the waiting position based on the combination of walking distance and full load rate.

Key words: urban rail platform, waiting position selection, influencing factors, Logit model, full load rate
