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. The processor may be reprogrammed to change the geographical area within which the vehicle is travelling. The result is the saving of time, gasoline and operator aggravation.

A method of eliminating the use of maps or other instructions by the operator of a motor vehicle who wishes to travel from a given point of origin over a selected route terminating at a point of ultimate destination comprising: A. providing a data processor completely contained within said motor vehicle for generating a given plurality of sets of data, each set representing a particular route within a given geographical area and each set including a plurality of data subsets, each subset including data indicative of a particular subroute to be taken in traversing said particular route, said data processor further including: a1. a manually operated route establishing input device for generating data indicative of the point of origin and the point of ultimate destination of said selected route; a2. selection means responsive to the manual actuation of said route establishing input device for selecting a particular selected set of said sets of data and for enabling the sequential generation of said plurality of data subsets making up said particular selected set of data; a3. a manually operated fetch next subroute input device for instructing said data processor to fetch the next data subset indicative of the next subroute, of said selected set of said sets of data; a4. output means responsive to the manual actuation of said fetch next subroute input device and the resulting generation of said next data subset for indicating to said operator the next subroute to be taken; B. manually actuating said route establishing input device to enable the generation of a plurality of data subsets of said selected data set; C. manually actuating said fetch next subroute input device upon the arrival of said motor vehicle at the point of origin of the next subroute for causing said output means to indicate to said operator the next subroute; and, D. manually actuating for a second time said fetch next subroute input device upon the arrival of said vehicle at the point of origin of the following subroute and so on until said motor vehicle arrives at said ultimate destination.
