Abstract: E-scooters have disrupted and altered the urban mobility landscape. During their introductory period, they have been commonly touted as part of a larger micromobility solution that erases equity barriers and solves the first-mile/last-mile problem. However, few studies in the nascent e-scooter literature have considered these claims. In this study, we used a d-efficient method to design and administer a stated choice experiment (SCE) to students at Portland State University (PSU) (n = 1,968). In the SCE, students were given a three-mode labelled choice set consisting of three travel modes: car, bike, and e-scooter + MAX light rail. (The e-scooter + MAX light rail choice is multimodal, with the e-scooter acting as the first-mile access mode). We generated attitudinal indices using exploratory factor analysis (EFA) in order to control for mode perception. To demonstrate the relationship of travel time and cost in addition to other covariates on mode choice, we estimated a mixed multinomial logit (MMNL) model. We performed elasticity and sensitivity analyses to uncover factors that encouraged first-mile/last-mile e-scooter usage. We then used the model to generate catchment area maps for multimodal trips in the Portland area.
