A system for alerting the occupant of a vehicle that the vehicle is in or approaching a zone of awareness. For instance, the system may be used to alert the pilot or flight crew of an aircraft that the aircraft is on or approaching a runway, and may identify the specific runway. Thus, the invention

A system for alerting the occupant of a vehicle that the vehicle is in or approaching a zone of awareness. For instance, the system may be used to alert the pilot or flight crew of an aircraft that the aircraft is on or approaching a runway, and may identify the specific runway. Thus, the invention also provides a method of reducing unintentional incursions of taxiing aircraft onto runways. The system generally includes a storage device or memory, a positioning system such as a GPS that typically repeatedly determines the location of the vehicle, an alerting device such as an alarm or display, and a processor, all of which are typically located on the vehicle. The processor typically compares the location of the vehicle with stored location information for various zones of awareness and initiates an alert when appropriate. The processor may take into consideration the velocity and direction of travel of the vehicle. Zones of awareness may be defined by coordinates, such as the end points of line segments. Audible alarms may include a voice warning, and may be able to be silenced until the vehicle leaves the zone of awareness. On aircraft, the system may reference the centerline of the runway, for example, alerting when the aircraft is within 150 feet of the centerline. The system may be disabled when the aircraft is in flight.

The method of claim 6 wherein said road level is determined by road size, road location, speed limit and number of lanes. 8. The method of claim 5 wherein said traffic condition comprises the average traffic speed. 9. A method of selecting the fastest dispatch route from at least one dispatch assignment to at least one dispatch destination, said method comprising: tracking the relative geographical position of a plurality of dispatch resources; identifying the geographical position of a dispatch destination relative to said plurality of dispatch resources; determining a set of routes from said plurality of dispatch resources to said dispatch destination; determining a traffic condition of each route of a set of possible routes; calculating the travel time of said each route of said set of routes; and selecting a route from a first set of possible routes with the lowest travel time. 10. The method of claim 9 further comprising receiving geographical position information from said plurality of dispatch resources determined by GPS. nance Production System", by Barry Sinex, application Ser.
