Shared mobility can include roundtrip services (a vehicle, bicycle, scooter, or other mode is returned to its origin); one-way station-based services (a vehicle, bicycle, scooter, or other mode is returned to a different designated station location); and one-way free-floating services (a vehicle, bicycle, scooter, or other mode can be returned anywhere within a geographic area). To help manage free-floating services, cities and shared mobility operators may use technologies like geofencing. Geofencing is a technology that uses GPS or RFID technology to create a virtual boundary, enabling cities to determine when and how often vehicles or equipment cross predetermined boundaries, as well as alert riders who operate in restricted areas.This Shared Mobility Policy Playbook provides an introduction and definitions of shared mobility services, mode-specific resources for agencies looking to develop policies in their community, and policy-focused tools demonstrating case studies and best practices for shared mobility.
