Well, if our local transit company has a GPS module in every its vehicle on a route and can watch all of them nearly real-time ("nearly" is something like updates every 30 seconds), and we are in Eastern Europe, then any transit authority can. There is no need to "crowdsource" it.

On the other hand, they aren't very good in communicating the information they have. The best thing we have is this: http://idsjmk.jrbrno.cz/ and Google Maps.

There are another problems that are not mentioned at all in the article. Service irregularities, either planned or not. There are frequent tram track repairs, street closures… So, what changes are there on my route, if any? Was the stop that I'm planning to get on moved behind the corner? Where exactly can I get on? And exactly means exactly, cellphone GPS can't tell you decisively if you are at the right side of the road, for example. And that is a crucial difference if you are planning to get on a bus.

And what if I'm waiting for a tram, and there was an accident somewhere and all the trams are delayed. What now? Was a reserve bus dispatched to replace it? When will it arrive? And where, if it's a segregated tramway and the bus can't use the stop?
