It operates transit service in three cities within Denton County, as well as the A-train, a regional commuter rail line to Carrollton.

LINK's bus routes were absorbed into DCTA's local Denton services (now called Connect).

In accordance with DCTA By-laws, the Board adopts the annual operating budget and is responsible for setting policy.

[6] DCTA Connect originally had ten routes (eight in Denton and two in Lewisville), but most were discontinued in 2021 and 2022 in favor of GoZone service.

UNT students, faculty, and staff can ride at no cost with their ID, while other riders can use standard DCTA fare.

[9] DCTA does not currently operate shuttles for Texas Woman's University or NCTC Denton, but both institutions are serviced by Connect buses (routes 6 and 7, respectively).

Riders can travel further to downtown Fort Worth using Trinity Metro's North Park and Ride Xpress (Route 63X).

[17] ADA paratransit in Denton County outside of DCTA Access's service area is provided by the nonprofit Special Programs for Aging Needs (SPAN).

DCTA Access also offers a non-ADA demand-response service for residents of Lewisville, Highland Village, and Denton that are disabled or elderly (65 years and older).

These trips can start and end anywhere within these three cities, but they are provided on a first-come, first-serve basis and are subject to capacity constraints.

[18] DCTA ridership fluctuates greatly with the academic calendar, as a considerable portion of passengers are UNT and TWU students, faculty, and staff.
