This tool provides users with an overview of the state of shared mobility and transportation trends in the top 25 most populous metropolitan areas in the United States. Using the tool, you can understand current mobility patterns, demographic characteristics, and available mobility options in each metro area and how they compare to others. You can interact with other tools and content on the MLC, such as the Shared Mobility GHG Benefits Calculator, learning modules, case studies, and key policies and pilot projects.
These data are estimated and based on the best available sources. If you notice anything that we might have missed please email. Full methods available here.

Fleet Size Details
* If exact fleet sizes are unavailable, fleet size caps are used.
Due to data availability limitations, this list does not necessarily represent every shared mobility operator. This data shows the general magnitude rather than exact service levels or vehicle counts.
* Fleet size is calculated by counting the number of available car share cars from each fleet’s website. As counts vary based on car availability and differ by day and time of day, these numbers are only rough estimates. See the Data Collection Methods and Sources document for more information.
Charging Equipment Level 1 provides a 2 – 5 mile range per one hour of charging using a standard 120 volt connection. Charging Equipment Level 2 provides charging through 240 volts, and provides a 10 – 20 mile range per hour of charging. Direct Current Fast Charging has a capacity of 480 volts and provides 60 – 80 miles per 20 minutes of charging.
Public-Private Partnerships (P3s) are one way to fund and support mobility projects. In some cases, a government entity will own transportation infrastructure and contract with a private company for service or operations. The number of P3s helps to illustrate how cities are working with private mobility operators; however, as the private sector takes a greater role in implementing services through permitting, P3s are not the only indicator of the growth of shared mobility.
The chart below shows the P3s that the MLC has tracked since 2016. These values only represent the P3s tracked during this period for the 25 metropolitan areas.
