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.

“These features provide customized travel time estimates that take into account a user’s driving habits, the characteristics of the vehicle being navigated, road conditions, seasonal conditions, traffic congestion and other factors,” the patent application reads, “which cannot be accounted for by conventional statistical calculations based on data samples obtained from a test vehicle or device traveling the route.”

The described system would take into consideration a plethora of factors, like stoplights and railroad crossings, and store the data on a server, time-stamped and indexed for easy access.
