Shared transport or shared mobility is a transportation system where travelers share a vehicle either simultaneously as a group or over time as personal rental, and in the process share the cost of the journey. It is a transportation strategy that allows users to access transportation services on an as-needed basis, and can be regarded as a hybrid between private vehicle use and mass or public transport. Shared mobility is an umbrella term that encompasses a variety of transportation modes including carsharing, Bicycle-sharing systems, ridesharing companies, carpools, and microtransit.
