The Regional Transportation Agency of Central Maryland, locally referred to as the RTA, is a transit organization providing fixed-route and paratransit services across Central Maryland. The RTA is made up of multiple jurisdictions including Anne Arundel County, Howard County, the City of Laurel, Northern Prince George's County, and Baltimore County.
In 2014, Howard County initiated the Regional Transit Agency of Central Maryland, recruiting Anne Arundel County to join areas served by Central Maryland Regional Transit claiming the centralized authority initiated, managed and funded through Howard County would save money in contract expenses. CMRT bid on providing services to these regions after July 1, but lost to First Transit.
In 2014, Howard County broke ground on a $7.2 million bus depot at Savage, Maryland designed to house 120 buses.
In 2023, RTA added route 505, the first route to serve Baltimore County.
In October 2023, RTA released the final draft of the Central Maryland Transit Development Plan (TDP), proposing future changes and improvements to RTA bus service between fiscal years 2024 and 2028.
, RTA operates 14 bus routes in Howard County, Anne Arundel County, Prince George's County, the city of Laurel, and Baltimore County.
RTA has a number of transit hubs where numerous bus lines meet. They include:
Bus fare can be purchased on the bus, at certain library branches, senior centers, online for shipping, and through the Transit app.
