A route exclusion list system permits the user to designate certain roads or areas that a navigation system should avoid when planning a route between a beginning point and a destination point. The route exclusion list system generally includes a database of road segments and a cost associated with the road segments, such as estimated time of travel across that road segment or estimated length of travel across that road segment. A display displays a map having a plurality of the road segments. A user input device permits a user to encircle and select displayed road segments. The cost associated with each selected road segment is increased thereby making it unlikely that the navigation system will use any of the selected road segments when determining a route between the beginning point and the destination point. The system can be operated independently of the navigation system and the increase in cost for each road segment can be associated with a specific period of time.
