Our team is developing a decision-support system for planning, designing, operating, and managing micromobility in U.S. cities. This tool is a web-based platform that 1) can crowdsource information from residents on traffic incidents such as crashes and near-misses; and 2) can help cities manage e-scooter parking and monitor equity policy compliance.
A conceptual framework to understand the relationship between e-scooters and public transit
