| Abstract | Bayesian belief networks have proven to be an effective technique for representing and
reasoning with uncertain knowledge. A Bayesian network is a graphical representation of a
probability distribution. Therefore statistical techniques can be used to construct Bayesian
networks from data.
This research presents a Bayesian network model for Air traffic trajectory conflict.
The purpose of the research is to aid the air traffic controller to control the aircraft. When the
air traffic is busy, the air traffic controller on the ground has a short time to consider the
situation for avoid air traffic conflict and must decide how to suggest the pilot on the aircraft.
However, it has many variables, which must be considered for safety such as weather, type of
fly and number of engines.
Therefore, the Bayesian network was built to estimate the air traffic conflict in
trajectory based on many variables, which concern air traffic environment and the controller
knows at that time. In this research, the Bayesian network model was built using eleven
variables. A user interface was constructed that permits the user to enter events and then the
response suggests the probability of the damage for the air traffic conflict. The user interface
is domain specific and does not require the user to have any knowledge of Bayesian networks.
Empirical evaluation shows the model to have 77.19 % accuracy when evaluated on a
database of 3,697 cases. |
