To provide a method of automatically deleting a traffic message that is associated with at least one directed segment and/or at least one node, in which traffic messages are automatically deleted at the earliest possible time while ensuring that the route segment affected by the traffic message is not traveled again, the traffic message is deleted when the sum of the resistances remaining between the current position and the destination is less than or equal to a reference resistance which is determined by the sum of the resistances remaining between a reference segment and the destination, the reference segment being the segment subsequent to the segment of the route, in the direction toward the destination, that is affected by the traffic message and that was the route specified before the traffic message was taken into account.
