Abstract: Navigation system and method comprising a server system with a navigation server (6) and a host server (7) connected to internet, having a first cartographic database (61) and a first routing engine, a mobile device (8) having geolocating means to determine a current location, having a second cartographic database (81) and a second routing engine, wherein the mobile device transmits a routing request to the remote server system, wherein the server system calculates a primary route (4) from the current location (3) to the destination point (2), said primary route comprising a list of maneuvering points each maneuvering point, wherein the server system calculates a list of waypoints located on the primary route, spaced away from the maneuvering points, the second routing engine establishing therefrom a secondary route (5), based on the waypoints and on the second cartographic database.

Abstract: Method and system of traffic information comprising a mobile device (1) connected to a connected host server (2) via a wireless network (4), wherein said host server (2) is adapted to download updated standard traffic information xml files (6) from traffic information server (3) connected to the Internet (5), wherein the method comprises the steps of identifying the current GPS location of the mobile device and transmitting said current GPS location to the host server, defining a relevant area surrounding said current GPS location of the mobile device, extracting, from updated standard traffic information xml files, road segments totally or partially included in said relevant area, preparing and compressing a relevant subset of traffic info data, transmitting it to the mobile device, processing said subset of traffic info data in the mobile device to display traffic information.
