A ground traffic control system for use in controlling the movement of an aircraft and various other vehicles on the grounds of an airport. The system and methodology involve, with regard to aircraft, the precursor transmission of a full packet of travel-route information (routes and waypoints) that is sent, according to operation of the system, as a singularity just prior to controlled travel of an aircraft. Portions of assigned travel routes that are based upon an assembly of waypoint-to-waypoint data are clearly communicated to an aircraft crew, including communication via specific visual mapping data and are armed with the capability of informing a crew visually exactly where it is in relation to assigned travel instructions. Similar methodology, enabled similar system structure, is used for the control of other airport-related vehicles.
