iOS 9 will add transit directions to its Maps service, the new data including schedules for buses, trains, subways, and ferries and will be available in 10 cities at launch later this year.
To answer the question as to where the transit data is coming from, Apple has updated its Apple Maps Acknowledgements webpage with a breakdown of where transit data from each city is coming.
The site reveals that the data will hail from twenty different sources, with each source providing data for a single city in most cases. For instance, three different sources are contributing transit data for Berlin and three other sources are contributing to San Francisco transit data. Some sources include Flixbus, Metrolinx, and MiWay. The full list of sources can be seen on the Acknowledgements webpage here.
