A new patent application from Apple suggests the company could be working on proprietary global positioning system software that would calculate road trip times and recommend routes, based on real-time data collected from numerous users, and uploaded to a centralized server.

In the recently revealed U.S. patent filing, Apple describes a system for obtaining drivers' personal travel data and using it to estimate driving times. Such a system could take into account speed, time of day, location, driving patterns, season, route type and features, traffic information, road conditions and location data.

Originally filed for in 2008, the patent could save drive times and other data on the local system, and also upload it to a centralized database where the data would be shared with others.
