Inspired by finding this logo:

Which led to this Memory Alpha entry:

Granted, the latter image is from an alternate present that Harry Kim found himself having to escape from per "Non Sequitur"...but he didn't seem to find the service's existence "out of place" while he was there. Therefore, it seems safe to assume that it existed in the "prime" reality, and that it's the successor to at least one - more than one? - of the real-worlds transit services of the San Francisco Bay region.
(Yes, public transit is a technology.)
