The Suburban Mobility Authority for Regional Transportation (SMART) is the public transit operator serving the suburbs of Detroit, Michigan, United States.

Beginning operations in 1967 as the Southeastern Michigan Transportation Authority (SEMTA), the agency was reorganized and renamed SMART in 1989.

SMART operates 45 bus routes (supplementing the Detroit Department of Transportation), plus paratransit and microtransit services.

SEMTA was charged to take over the ownership and operations of the fractured regional transit systems in Macomb, Oakland, and Wayne counties, including the city of Detroit.

[3] That same year, SEMTA acquired a commuter train service between downtown Detroit and Pontiac from the Grand Trunk Western Railroad.

[citation needed] Beginning in 1983, SEMTA oversaw the construction of the Detroit People Mover, which was conceived as part of a much larger project of light rail lines and a downtown subway.

[2][14] In order to prevent possible service cuts, SMART raised its fares by $0.50 on December 1, 2009; there was also a $0.50 charge added to regional monthly pass users and DDOT transfers.

[23][24] The city's exit was blocked by a judge in May, however, and Auburn Hills remained a member until the opt-out system's abolition in 2023.

[25] Macomb Township's board of trustees similarly passed a resolution in March expressing interest in opting out of SMART services.

[27] Approved by voters in November 2022,[28] the millage abolished opt-out system in Oakland County, allowing for the expansion of SMART services to the far reaches of Metro Detroit.

[31] The following month, SMART introduced their first electric bus, one of four Proterra ZX5 units purchased by the agency with a Federal Transit Administration grant.

[20][33] Since 1995, SMART has been funded in large part by a millage,[8] renewed by voters in member communities in midterm election years through 2022.

[35] In 2022, the SMART millage in Macomb and Wayne counties was extended to five years, and moved to the November general election ballot.

[29] The proposal appeared on the November 2022 general election ballot in all Oakland County communities, and passed with 57% of the vote.

Frequent Affordable Safe Transit (FAST) is SMART's flagship service; its limited-stop bus routes serve as the main arteries of the network, connecting the suburbs with downtown Detroit.

Five FAST routes currently operate along three major Metro Detroit avenues - Gratiot, Michigan, and Woodward - with service every 30 minutes on weekdays, and stops roughly every mile for most of their lengths.

[38] (River Rouge) Select late-night trips start and end at Michigan + Schaefer (Grosse Pointe Park) No Sunday service west of Lodge Freeway (truncated to 10 Mile + Evergreen) No Sunday service west of Woodward Avenue (truncated to Detroit Zoo) (West Bloomfield) Commuter routes In addition to FAST and local routes, SMART operates seven commuter express routes between Downtown Detroit and the suburbs during weekday rush hours.

trips SMART and DDOT share a unified fare structure, known as Dart, with most of their passes accepted by both agencies.

It is available to residents of all ages, provided they live more than 1/3 of a mile away from a fixed route, though the distance requirement is waived for seniors (65 or older) and disabled riders.

[42][43] The service operates similar to ridesharing; a passenger books a ride via telephone or through the Flex smartphone app, and a marked minivan picks them up and takes them to their destination.

"[45] The fleet used for Flex, owned by Avis Budget Group,[45] consists mostly of Chrysler Pacifica and Toyota Sienna minivans.
