I've first seen this in Moscow around 2018 (in Google Maps) and then in Ivano-Frankovsk in 2021 (some local custom app). I think such live maps are the best use of public funds one could imagine.

I dunno, I think there's one better use and that's funding a federated framework for this so any transport network can just plug into the system as a source and any client can plug in as a consumer.

		Well, there is this: https://mobilitydatabase.org/ which sounds about what you're looking for, although it is still up to the client to combine the feeds its looking for.
