On this website one can see on the OSM map not only the locations of 
stops, but the positions of the public transportation vehicles 
themselves in real time. Here are the positions of the tram (light 
train) #28 in the city of Odessa: 
https://www.eway.in.ua/ru/cities/odesa/routes/1

It is very convenient as one does not have to wait at the stop but can 
leave home or office just in time to get on the tram. So no need to have 
too many vehicles on the route as one can comfortably plan the trip even 
if there are not many.

I think such dynamic real-time mapping is the future of public 
transportation and cartography in general, though I am not sure how it 
is implemented on this particular website. I assume they use GPS 
sensors. But how they transmit locations to the map's server constantly 
I am not sure.
