in speedrunning (playing games with the sole purpose of completing it in the lowest time possible) it's the term for unassisted (see TAS for tool-assisted runs) runs in the community. It stands for real-time attack.

I just got the RTA world record for Super Mario Bros!

RTA 

Cleveland's Regional Transit Authority, aka, the Ride Through Africa. Titled as such because a large proportion of riders are Black.

Shoot, gotta buy a bus pass so I can take the RTA to go buy some 40s and some Black and Milds.
