Abstract
A navigation unit and system for land navigation particularly useful for vehicle travel. The navigation unit includes a routing program and programs to be used in conjunction with the routing programs. The programs used in conjunction with the routing program process current traffic information for segments of mapping information. The programs provide for a dynamic road speed sensitivity computation which allows the display of current speeds for various segments of mapping information which can be used to display a selected route with a parameter, such as estimated time for the trip, for the route computed based on current travel information. The unit also can contain a program for allowing the user to set an alert value for a parameter, and the program will alert the user when the current route satisfies the alert requirements, and computes one or more alternate routes that the user can select and display.
