Hello there,

I'm Markus Windegger, I'm the maintainer of the data on opensasa.info (it was open.sasabz.it).

I can confirm that we have donated the bus stop data as a data donation to osm.

First of all some comments about public transport data:

- bus stops are not as dynamic as you thought. Most of the europe countries have strict regulations about bus stops (and train-stops and metro-stops too). So the companies don't chenge them, as it is a very burocratic work.

- bus routes are very flexible (they change more often than bus stops) and they were a little bit complexer than you think. Bus routes consist of a general line-number and description, which is a general route, not even with coordinates. There exists many variations of a bus line, depending of the time, of days and sometime depending of seasons or months. So a line can have more than one instance on the osm-map.

- most of the european pt-companies (I don't know anything about the american, asian or african ones) in the last years have adapted programs, which are using the standard model of pt - data, which was developed by an association named vdv [0]. In this data model it is possible to transfer a full dataset of the hole bus-schedules from one system to another. And this for planned data (vdv 452) and data like the schedules for the workers and for the busses.

- this datamodel in europe is becomming an european standard for the realtime data exchange, called SIRI. Gtfs is not used so much, because most of the companies need to transfer the data, and this is an additional work. Additional work is in most companies not possible (because they don't have computer engineers that understand the difference or whatever...).

I hope you understand most of this (my english isn't very good). If you have more questions about the public transport, please ask. I'll help you as much as I can.

P.s. I'm not the person to discute the licence. The licence was decided from the ceo, and I do my best to change the licence in a cc0 in the future...:-)
