    Inequality in Shared Micromobility: Global, National, and Local Perspectives
    (University of Oregon, 2024-08-07) Meng, Sian; Brown, Anne
    Shared micromobility systems, such as shared bicycles and e-scooters, have seen substantial global growth over the past decade. Although these systems offer affordable, flexible, and environmentally friendly transportation options, their rapid proliferation has raised significant equity concerns. The unequal distribution of shared micromobility services may limit access for the transportation disadvantaged, which could exacerbate the inequalities in the existing transportation system. This dissertation examines inequalities in shared micromobility through three studies at global, national, and local scales. The global-level study utilized world city theory to analyze the establishment and expansion of shared micromobility companies worldwide and employed mixed methods to explain what leads to the inequality in system distribution across cities. This study reveals that shared micromobility industries are associated with the world cities of ride-hailing, advanced producer services, and startups. Factors such as low demand for shared micromobility, unfriendly regulatory environments, and negative public and governmental attitudes towards shared micromobility are the major barriers to the adoption of shared micromobility systems at the city level. The national-level study examines the effects of policies aimed at equalizing resources and opportunities on vehicle and trip inequalities within shared micromobility systems in the US. Resource-equalizing policies for shared micromobility aim to equalize the distribution of shared micromobility vehicles, which directly alleviates inequalities in vehicle distribution and indirectly lessens trip distribution inequalities. In contrast, opportunity-equalizing policies subsidize people with less capability to use shared micromobility, such as low-income, unbanked, and non-tech-savvy people. However, policies for equal opportunity are less effective in addressing inequalities in shared micromobility. The local-level study investigates the impact of introducing shared e-scooters on existing transportation modes—bikeshare, railway, bus, taxi, and ride-hailing—in Chicago’s transportation equity priority areas, where residents face increased mobility barriers. The introduction of shared e-scooters results in distinct effects on different transportation modes between equity priority and non-equity priority areas. In the equity priority area, shared e-scooters significantly boost bikeshare usage and reduce taxi usage. In contrast, in the non-equity priority area, shared e-scooters notably reduce trips by bikeshare, railway, and taxis, but increase ride-hailing trips.
