The Shared Autonomous Mobility Act of 2026 aims to modernize transportation by facilitating the development and deployment of autonomous shared mobility vehicles, such as self-driving buses. The legislation seeks to enhance public transportation options and alleviate traffic congestion through the use of federal grant funds designated for this purpose. Central to the Act is the establishment of a new grant program overseen by the Secretary of Transportation, which will provide competitive grants to eligible entities, including transit agencies and private companies.
