E-scooters as transit feeders: insights from revealed preferences of shared e-scooter users

While e-scooters are increasingly used for short-distance trips, concerns persist regarding their effective integration with public transit. This study sheds light on the factors shaping revealed preferences for using e-scooters as transit access/egress mode by surveying 2,126 shared e-scooter users. We developed a Generalized Structural Equation Model (GSEM) to analyze the impacts of sociodemographic, transportation-related, and attitudinal factors on the frequency of e-scooter integration with transit. The results identified four attitudinal variables-transportation efficacy, variety seeking, environmental concern, and perceived safety-as the main drivers. Regarding demographic factors, experienced e-scooter users are more likely to integrate with transit, and women are less likely to use e-scooters in integration with transit. Furthermore, the findings underscored the role of transportation variables, households without personal vehicles, and access time to e-scooters under five minutes. The insights gained from the study help urban planners enhance e-scooter-transit synergy and advance sustainable micromobility use.
