Analysis of dynamic choice behavior at subway exits

Abstract

In high passenger flow scenarios, guiding passengers to the appropriate facilities in a subway station is essential to improving overall efficiency. To investigate whether passengers alter their choice of vertical transportation facilities due to changes of the visual field during the outbound process, a questionnaire-based experiment on facility choice was conducted. Data were collected from 99 valid respondents through online recruitment. Two observation points with different perspectives were set in the experiment to analyze the passengers’ psychological changes in decision-making. The results show that respondents will adjust their choice of vertical transportation facilities during the outbound process. At observation point 2, where the number of elevators and the number of passengers queuing in front of elevators are available, the percentage of respondents choosing elevators increased by 70 %. These findings provide insights into passengers’ dynamic decision-making regarding vertical transportation facilities and offer guidance for facility selection modeling and subway passenger flow management.
