Transit directions, along with a trip-planning feature and indoor maps, is rumored to be a cornerstone feature of Apple Maps in iOS 9. According to 9to5Mac on Tuesday, transit directions in Apple Maps are set to launch in approximately a half-dozen cities across the United States, Canada and Europe, with more to be added at a later stage.
In fact, as AppleInsider first reported three days ago, Apple's mapping service in China is better than Apple Maps in Europe or the United States.
