Fall 1997 Seminar Series
Issues in Air Traffic Control
As the Air Traffic Control system moves toward an environment of free
flight, restrictions will be placed on the free movement of aircraft only to
preserve safe separation. It is important to understand the frequency and
severity of the situations which will require these restrictions in order that
the separation assurance system can function effectively. A mathematical model
will be described which clearly establishes fundamental relationships between
traffic densities, flow structure, and alarm rates experienced by aircraft.
Radar tracks recorded at MIT Lincoln Laboratory are used to determine patterns
of the current traffic. It is concluded that alert rates can be dramatically
reduced by using intent-based maneuver constraints in the detection process.
