Influence of Shared Bicycles on the Sharing Rate of Access Modes to Urban Rail Transit Stations and the Construction of Modal Split Model

Objective With the advantages of high turnover rate, short parking time, and low occupation of public parking resources, shared bicycles have gradually become an emerging alternative in urban rail transit access modes. To provide a scientific basis for planning non-motorized access transportation facilities, it is necessary to study the impact of the introduction of shared bicycles on the choice of access modes to urban rail transit stations (hereinafter referred to as station access mode) and establish an access mode split model.

Method Taking Shanghai as the research object, an online questionnaire is used to investigate the current choice state of station access mode after the introduction of shared bicycles. The influence of access time, access cost, gender, age, and monthly income on passengers' choice of access mode is analyzed. A disaggregate Logit model is used to refine the modal split model for station access mode after the introduction of shared bicycles, and the accuracy of the model is further validated.

Result & Conclusion  Walking remains the dominant access mode after the introduction of shared bicycles, but its share rate significantly decreases as a larger proportion of passengers switch from walking to shared bicycles for access. The modal split rate of station access mode exhibits a significant correlation with access time and cost, demonstrating a trend of the share decrease with the increase in access time and cost.
