Patent Images
1. A system for classifying and tracking traffic in an airport having at least one runway and at least one taxiway, the system comprising:
- one or more inductive loops positioned at predetermined locations near the runway and the taxiway to generate a signal when a vehicle passes near an inductive loop;
means for assigning a classification to the vehicle in response to the signal generated by the inductive loop;
means for determining a position of the vehicle in the airport as the vehicle passes near the inductive loop;
means for calculating the speed of the vehicle as the vehicle passes over the inductive loop; and
means for displaying a representation of the vehicle in the airport, the representation of the vehicle indicating the classification of the vehicle, the position of the vehicle, and the speed of the vehicle.

Abstract
A system and method for classifying and tracking aircraft and ground vehicles on the grounds of an airport is provided. The system generates a signal as a vehicle passes over a sensor under the taxiways or runways and analyzes the signal to determine a signature for the vehicle and the estimated speed of the vehicle. The determined signature and estimated speed may be used to track the movement of the vehicle around the grounds of the airport.

10. The system of claim 10 further comprising means for fusing the track of the signal to an existing track if the incoming signal matches a signature of an already existing track.
-
16. A system for classifying and tracking vehicles on the grounds of an airport, the airport having at least one runway and at least one taxiway, the system comprising:
-
means for generating a signal corresponding to a vehicle on the grounds of the airport passing over an inductive loop;
means for generating a signature and an incoming track for the vehicle based on the signal;
means for comparing the signature to the signatures of previous signals to identify matching signatures; and
means for combining the track of the vehicle with a track of a previous signal when matching signatures are identified so that the movement of the vehicle over the grounds of the airport is tracked.
