Simulation model for efficient and safe sectorization in an air traffic area control center
No full textThe air traffic control system gives guidance to prevent collisions and manage efficient traffic flow. Enroute air traffic controllers are persons in charge to expedite and maintain a safe and orderly aircraft flow over a given geographic area through the use of long-range radar. The day-to-day problems faced by the air traffic control system are primarily related to the volume of air traffic demand placed on the system, and weather. Controllers work in facilities called Area Control Centers (ACCs). The area controlled by each ACC is subdivided into vertical and horizontal sectors. Today technologies allow a flexible “sectorizations” of an ACC depending on the traffic demand. Controller workload is a function of the number of aircraft flying in the same sector and of safety constraints; this implies that there is an upper limit on the number of planes that can be simultaneously controlled. Different sectorization may affect this limit.
We propose an innovative and flexible simulation model (implemented on a PC by means of a low cost package) based on expected traffic data, that may help decision makers in determining the ACC sectorization in order to properly address traffic demand. Experiences on the Padova ACC in Italy are reported
Passenger and baggage flow in an airport terminal: a flexible simulation model
No full textThe lack of a friendly and flexible operational model of landside operations motivated the creation of a new simulation model adaptable to various airport configurations for estimating the time behaviour of passenger and baggage flows, the elements’ capacities and the delays in a generic airport terminal. The validation of the model has been conducted by comparison with the results of previous research about the average behaviour of the future Athens airport. In the mean time the proposed model provided interesting dynamical results about both passenger and baggage movements in the system

A new highly flexible simulation model for an adaptable, efficient and safe sectorization in an air traffic area control center
No full textThe air traffic control system gives guidance to prevent collisions and manage efficient traffic flow. Enroute air traffic controllers teams in charge to expedite and maintain a safe and orderly aircraft flow over a given geographic area through the use of long-range radar. The day-to-day problems faced by the air traffic control system are primarily related to the volume of air traffic demand placed on the system, and weather. Controllers work in facilities called Area Control Centers (ACCs). The area controlled by each ACC is subdivided into vertical and horizontal sectors. Today technologies allow a flexible “sectorization” of an ACC depending on the traffic demand. As there is an upper limit on the number of planes that can be simultaneously controlled by the same team of two persons, different sectorizations may affect this limit. We propose a new and highly flexible simulation model (implemented on a PC by means of a low cost package) based on expected traffic data that may help decision makers in determining the ACC sectorization in order to properly address traffic demand. The simulation model permits to describe air traffic control behaviour under changes of sectorization to be decided during the day without a rigid plan. Moreover new sectorizations different from the currently adopted one are suggested for the three areas controlled in Italy
