Uncovering individual-level determinants of shared e-scooting travel frequency

• Multimodal and reduced-fare transit users are more likely to frequently use shared e-scooter services. • Regular online shoppers, as a tech-savvy group, exhibit a greater propensity for consistent shared e-scooter use. • Residents in job-rich, transit-accessible areas are more likely to be frequent users of shared e-scooter services. • A higher density of road network is significantly associated with regular shared e-scooter use. • A higher walkability score is positively correlated with frequent shared e-scooter use. Shared electric scooter services (SESS) can potentially contribute to sustainable urban transport. However, utilization rates remain low and cast doubt on their cost-effectiveness, energy and resource efficiency, and environmental benefits. While aggregate-level studies have examined shared e-scooter usage, individual-level factors remain underexplored. This study addresses that gap using a behavioral survey of 1,425 responses. We employed a random parameter ordered probit model to quantify the factors that influence the frequency of SESS usage. Study findings reveal a gender and generational gap, with women and older adults less likely to utilize e-scooter sharing compared to men, Millennials, and Gen Z. Additionally, low-income individuals and those without vehicles have a higher probability of being regular users. Multimodal transit users and individuals who receive reduced-fare transit are more likely to use SESS frequently. Individuals who shop online regularly, often a tech‑savvy group, are also more inclined to be frequent users. Furthermore, our findings indicate that built environment attributes are important. Specifically, the results show that living in areas with higher employment entropy, denser road networks, greater accessibility by transit, and highly walkable environments increases the likelihood of frequent SESS use.
