The position and/or movement of at least one device for a user can be monitored over time, and various types of information inferred based on patterns in that user behavior. A device can determine various locations where a user typically stays for a period of time, as well as the routes the user takes to get to those locations. Based upon time, date, and various other information, the device can infer the type of location and/or route, as well as the likelihood that the user will take a given route to one of those locations at any time. By being able to infer future actions and locations of the user at certain times, a device can proactively provide a variety of functionality to the user, such as to provide suggested alternative routes, move meetings, notify others of estimated times of arrival, and perform other such tasks.
