<p>A first route is calculated between start (SO) and destination (ZO) from map data. A notional starting location (SO1) is determined on this route. A route is calculated between the notional location (SO1) and the destination (ZO). This second route is compared with the corresponding part of the first route, especially in terms of length or traveling time. If appropriate, the corresponding part of the first route is replaced by the calculated route between the imaginary starting location (SO1) and the destination (ZO). An independent claim is included for the corresponding navigation system.</p> |
