In addition to stops at the County Hospital healthcare facilities and local pharmacies, the service zone includes stops that help connect Martinez residents to their community, including residential areas, shopping districts, and downtown Martinez.

May’s Shared AV

May Mobility equipped a fleet of seven Toyota Sienna Autono-MaaS vehicles with its patented Multi-Policy Decision Making (MPDM) AD technology.

MPDM uses in-situ AI to learn in real-time by imagining thousands of "what-if" scenarios every second while it drives and then commits to the safest and most comfortable maneuvers within milliseconds.

Each shared AV seats five passengers and all will have an attendant on board to answer questions and assist with passenger entry and exit if needed.

Three of the AVs are also wheelchair accessible, with an ADA-compliant wheelchair ramp allowing entry and exit via the rear of the vehicle. The wheelchair-accessible vehicles seat up to three passengers, including one wheelchair user.

"We're excited to see how our patented MPDM technology will service local residents and contribute to the broader adoption of AVs."
