Abstract: A method of providing traffic information is described, together with a device for performing the same. The method comprises determining a location of a mobile device, receiving traffic information, and determining, with respect to a trip database storing information indicative of a personal road network of a user of the mobile device, whether traffic information associated with one or more road segments in the personal network within a predetermined distance of the current location has been received. One or more no-jam events are generated for respective road segments in the personal network for which it is determined that no traffic information has been received.

Abstract: A method of predicting a destination of a user of a mobile device is described, together with a device for performing the same. The method comprises determining a location of the mobile device, and executing a route search algorithm with respect to a trip data-base. The trip database stores information indicative of a personal road network of a user of the mobile device, one or more road segments in the personal road network being associated with a respective destination location, and cost information associated with road segments in the personal network, the cost information being based, at least in part, on traversal information in the trip database.

Abstract: A method of providing route attribute information is described, together with a device for performing the same. The method comprises accessing information indicative of a primary route to a destination location determined with respect to a trip database storing information indicative of a personal road network of a user of a mobile device, and an attribute of the primary route. One or more alternate routes to the destination location are determined, together with an attribute of each alternate route. Attribute information associated with at least one alternate route to the destination is output when a location of the mobile device is proximal to a decision point of the personal road network.
