Abstract: A system and method for reducing the number of irrelevant warnings regarding traffic-related features for a non-navigation-guided trip including a position-determining device to determine a position of the vehicle from received signals; a storage device for storing map data representing courses of the roads; a route-calculating device for calculating a route along the courses of the roads; a receiver for receiving information regarding the nature and position of a traffic-related feature; a device for determining relevance of the information received based on whether an aerial distance of the position of the traffic-related feature from the vehicle falls within a first predetermined value; the aerial distance along a possible route falls within a second predetermined value and the number of turning maneuvers required falls within a predetermined maximum number; and a warning device for issuing a warning when these criteria are recognized as having been met in the relevance determining device.
