INTRODUCTION

The Solano Transportation Authority (STA) is a Joint Powers Authority comprised of

members including the cities of Benicia, Dixon, Fairfield, Rio Vista, Suisun City, Vacaville, and

Vallejo, and the County of Solano. The STA serves as the Bay Area County Transportation

Agency (BACTA) for Solano County and is responsible for coordinating countywide

transportation plans, programs, and projects under a Joint Powers Authority among the

Cities and County of Solano.

The STA manages transit services on behalf of the City of Suisun City and the City of Rio Vista.

The STA will provide management services on behalf of the City of Dixon for the fiscal year

of 2026-27.

The City of Rio Vista initiated public transit service in July 1980 under the Rio Vista Transit

banner by providing weekday demand-response service open to the general public. In

January 2006, Rio Vista Transit evolved into Rio Vista Delta Breeze, a deviated fixed-route

service. In an effort to address low ridership and high operating costs, in January 2007, the

City reduced the level of transit service to a modest “lifeline” operation while converting its

local deviated fixed-route service (Rio Vista/Isleton City Circulator) to a general public dial-

a-ride service. Since then, the City has continued to adjust services to ensure productive

routes are maintained and operating revenues and expenses are kept in balance. The service

currently uses both a telephone and a smartphone application on-demand system.

In 1990, Suisun City partnered with the City of Fairfield to provide local transit services

linking Fairfield and Suisun City. However, as of January 3, 2023, the City of Suisun City

partnered with the STA to provide transit management services. The service operates one

fixed route and provides dial-a-ride service within the city of Suisun City, with ten select

locations available outside of Suisun City. This service is known as Suisun Microtransit. The

service currently uses both a telephone and a smartphone application on-demand system.

The City of Dixon operates a public dial-a-ride transit system, which provides curb-to-curb

transit service within Dixon. With the elimination of school busing, the city introduced a

school subscription service, and students enter a lottery to register and ride each school year.

Service to neighboring Davis and Vacaville is exclusively available to ADA qualified riders.

The service has been operating since 1983 and is named Dixon Readi-Ride. The service

currently uses a telephone reservation system.

SERVICES TO BE PROVIDED – SCOPE OF WORK

STA, in partnership with the City of Rio Vista, the City of Suisun City, and the City of Dixon,

requests proposals from qualified vendors to provide solutions to enhance wheelchair

accessible vehicle (WAV) transportation services to operate on-demand (within 24-hours of

ride request). The service to be provided must enable existing WAV services to operate via a

technology application or similar dial-a-ride system. This service would be utilized by two

operators, Rio Vista Delta Breeze and Suisun City Microtransit, with the option to add a third

operator, Dixon Readi-Ride. These operators have already established trained drivers and

accessible vehicles. In Rio Vista, the service would be focused on supporting mobility in the
