Buried in Apple's statement on how the iPhone tracks a user's location data, the company admitted it was collecting anonymous location information to create a "crowd-sourced traffic database" that will be part of a future "improved traffic service."
The thing is, there's already a traffic service on the iPhone, provided by Google. If a user launches the Maps app and selects "Show Traffic," the map overlays colors on roads that show traffic congestion. Google gets the traffic data by—surprise!—crowd-sourcing it, aggregating information from Google Maps users who have approved the app for location services on their mobile devices.
Apple's statement reveals that the company is working on its own version of such a service. Whether that service will be something that Apple will use to improve traffic in Google Maps, or if Apple will launch a competing maps app, or something else entirely isn't known. Apple didn't respond to multiple requests for comment on the topic.
