Integration of Shared Micromobility with Public Transit: A Systematic Literature Review

Shared micromobility services have become increasingly prevalent and indispensable as a means of transportation across diverse geographical regions. Integrating shared micromobility with public transit can offer opportunity to complement fixed-route transit networks and address first and last mile issues. To explore this topic, a systematic literature review was conducted to consolidate knowledge, analyzes research achievements and best practices, and provides future research recommendations. The study examined 108 journal papers from the Web of Science Core Collection from 2016 to 2022, along with grey literature. Citation and co-citation analysis were performed to build and illustrated the literature's bibliometric networks. This analysis categorized the literature into four major study themes: policy, sustainability, the interaction between shared micromobility and public transportation, and infrastructure. The implementation approaches of integrating shared micromobility and public transportation in different cities were classified into four categories: physical integration, payment and fee integration, informational integration, and institutional integration. The findings indicate that the relationship between shared micromobility and public transportation varies with spatial-temporal conditions and population density of the city. Overall, integrating micromobility with public transit can offer faster and more cost-effective mobility options for most trips, contributing to urban resilience, better air quality, lower greenhouse gas emissions, and livable communities.  Based on these insights, further research is recommended to explore dynamic and context-specific strategies for successful shared micromobility and public transit integration, considering diverse urban settings and demographic factors.
