A Study on Pedestrian Choice between Stairway and Escalator inTransfer Station Based on Floor Field Cellular Automata

摘要

Stairway and escalator are main transfer facilities in the station where pedestrians make choicesbetween them. A good understanding of pedestrian choices is helpful to raise the efficiency oftransfer stations and lower the probability of disasters, such as stamps caused by congestion.This paper studies the choice behavior of pedestrians using random utility theory and floor fieldcellular automata. Among the factors influencing pedestrian choices, there are non-quantitativeones and quantitative ones. Thus, a method combining qualitative description and quantitativedescription is adopted. Subsequently, a logit model is presented to mimic the choice behaviorsof pedestrians. In this model, there are three new important parameters, including familiarity,walking disutility, and time pressure. By using micro-simulation, a sensitivity analysis for theseparameters is conducted. Besides, a counting rule based on Large Number Law is presentedto count the real data in transfer stations in Shanghai. After comparing the sensitivity analysisresults and measurement data, several reference values of the three important parameters areobtained in uncongested and congested situations respectively.
