History

In 1963, legislative groundwork began for the establishment of a public transit special district in Stockton, and in 1965, the Stockton Metropolitan Transit District began providing service for the residents of Stockton. In late 1979, SMTD moved operations from Grant and Channel Streets to its current Lindsay Street facility. In 1985, SMTD adopted the nickname “SMART.” In 1990, SMART began providing fully accessible fixed route and Dial-A-Ride services for the elderly and persons with disabilities under the Americans with Disabilities Act of 1990.
In 1994, enabling legislation expanded SMART’s service area to the San Joaquin County border, bringing with it a name change to reflect its expansion – San Joaquin Regional Transit District, or SJRTD for short. That same year, SJRTD expanded its Interregional Commuter service to offer additional routes to commuters traveling to the Bay Area and Sacramento. In 2004, SJRTD adopted “San Joaquin RTD” as its new corporate identity and developed a new logo. That same year, RTD introduced low-emission diesel-electric hybrid buses via its “Flower Bus,” with a full-wrap sunflower display designed to complement the slogan “A Breath of Fresh Air.” At the end of 2006, RTD opened the Downtown Transit Center for the public, with a floor for employee offices. In 2017, by converting its route 44 to electric buses, RTD became the first transit agency in the United States to operate a fully electric BRT route.

BRT Express

BRT Express is RTD's express bus service and uses uniquely branded, low-emission diesel–electric hybrid buses that arrive at their stops every 15 minutes during weekday peak hours and every 30 minutes on weeknights, weekends, and holidays. BRT Express passengers are required to have a valid RTD bus pass or ticket to ride. Fare vending machines, located at BRT Express stops and the Downtown Transit Center, are available for passengers to purchase single ride and all-day passes. BRT Express uses the same fare structure and passes as RTD’s regular fixed routes and passes issued by the Fare Vending Machines can be used on any of RTD's regular fixed routes that operates within the Stockton Metropolitan Area.

The Downtown Transit Center (DTC)

Nearly all RTD routes connect at the DTC, which has 20 sheltered, off-street bus stops as well as additional street side stops on the north and south sides. The DTC building incorporates the façades of three historic buildings on its front elevation. The first floor of the DTC has a waiting area, public restrooms, and a customer service center where riders can get maps and schedules, purchase fares, and make customer comments. RTD leases of retail space for a restaurant on the east end, and a police satellite station provides the DTC with two RTD-contracted police officers. A boardroom available for public meetings occupies the west end of the first floor and RTD administrative offices occupy the rest of the building.
On average, 6,000 people use the DTC each weekday.
