Abstract: A routing computer is provided for eliminating the use of maps or oral or written instructions by the operator of a vehicle who wishes to travel from a given point of origin over a selected route terminating in an ultimate destination, such computer including a keyboard for instructing a data processor that the driver wishes to travel over an often unknown route between a known point of origin and a known ultimate destination. The data processor produces one selected set of data corresponding to the unique selected route, which set of data includes a plurality of data subsets, each of which produces a visual indication of the various subroutes to be taken while the vehicle traverses the journey. The data processor also produces indications of the estimated time that remains before the vehicle reaches the ultimate destination, and the estimated miles to go. Circuitry is also provided for causing the computer to indicate alternate recommended routes in the event of a traffic tieup.
