'The application of operational research to European air traffic flow management'

CITOM stands for the City Traffic Operations Management in the Philippines. It is responsible for overseeing traffic flow, enforcing traffic regulations, and managing road safety within the city.

The phrase should be air space containment it means to keep area used for air traffic clear of intrusion and the other phrase should be air traffic control which is managing the air traffic in the air space containment area to avoid collisions and other dangerous incidents whether accidental or intentional

Neither - an air traffic controller is a person, not hardware or software. They are responsible for air traffic flow.
