Hello!
I am Mikołaj Kuranowski.
I do a lot of stuff with public transportation data processing. I believe that the more open data on public transit we have, the better. That's why I publish GTFS feeds for a lot of cities in Poland, and I'm always looking for new cities to expand. I can help you create your own GTFS, as long as you agree to make it public. That's the whole point ️😉!
There's also a page where you can take a look at live positions of Warsaw buses and trams, but I actually made is as a way of debugging my GTFS-Realtime feed, but hey, it's useful nevertheless!
