In the context of the development of smart cities, the number and types of shared mobility solutions, such as carsharing and bikesharing, have increased in recent years. While the services are generally becoming more popular, there are comparatively few women among the users. With a view to gender-equitable mobility, this literature review explores gender-specific reasons for this low use of shared mobility solutions. Based on 35 relevant studies from multiple databases and disciplines, we identified four overarching barriers related to: security, availability, simplicity, and costs. By identifying these barriers and the reasons for them, and by linking them in a self-developed conceptual model with starting points for potential actions to address these issues, this literature review contributes to gender-equitable mobility.
