This study explores travelers’ preference for shared micromobility in the context of last-mile travel from shared parking lots to their final destination in the city center. Based on the results of the stated preference experiment and error component logit model incorporating latent variables, we found that the preference for shared micromobility is affected by the uncertainty of availability as well as both travel time and fare. More specifically, our alternative-specific part-worth utility approach shows that their marginal effects are non-linear, and this suggests several policy implications. Also, we found that there is a significant substitution between shared micromobility modes. Furthermore, various latent perspectives, including safety and management concerns of shared micromobility, have significant impacts on the preference.
