Analysis of a network usage record identifies activities and associated activity information of the mobile device. A series of consecutive movements of the mobile device along a path of locations is determined from the activity information. Historical sets of routes of the mobile device are accessed. Each route is a set of locations from an origin location to a destination location of the route. At least one common route is ascertained from the set of routes. The locations in each common route include all of the locations on the path. The origin location and destination location of each common route is the origin location and destination location of the path, respectively. A common route of the at least one common route is designated as the traveled route of the mobile device.
