May Mobility Teams to Launch AV Shuttle Service in California

California’s Contra Costa Transportation Authority (CCTA) and May Mobility launched PRESTO, a shared autonomous vehicle (AV) service for the general public in Martinez and Contra Costa Regional Medical Center (County Hospital) patients.

The goal of the service is to improve access to healthcare in the area by providing another reliable and convenient mode of transportation.

PRESTO Service

The free service will run Monday through Friday, first offering County Hospital patients rides from 2 p.m. to 6 p.m. and then opening to the general public from 6 p.m. to 10 p.m.

Patients can book rides to or from the County Hospital and to a preferred pharmacy from a set list of locations by calling or by arranging travel with a hospital representative.

From 6 p.m. to 10 p.m., the service will be open to all residents in the area. Those interested can book rides to a list of designated stops within the service zone by using the May Mobility app, powered by Via, or by calling.

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.

"May Mobility is dedicated to filling gaps in public transportation. With the PRESTO shared AV pilot in Martinez, we're redefining how communities connect and move," said May Mobility CCO Manik Dhar. "We're excited to see how our patented MPDM technology will service local residents and contribute to the broader adoption of AVs."

CCTA and May Mobility have also partnered with County Connection, which provides fixed-route and paratransit bus service for communities in Central Contra Costa County.

The Future of AVs at CCTA

Passenger feedback will play a critical role in shaping the future of autonomous mobility, as data from the City of Martinez PRESTO pilot will be used by federal transportation officials to advance standards in automated mobility.

The pilot is funded by a grant from the U.S. Department of Transportation. Martinez marks the third location where CCTA has introduced an autonomous vehicle pilot program.
