Abstract: A device, system, and method estimate aircraft taxi times. The method includes receiving a request for a taxi estimate, the request having request values for factors. The method includes determining an interdependency among the factors based on information entropy and information gain. The method includes generating a decision tree based on the factors and the interdependency, each factor of the decision tree having a corresponding threshold value. The method includes estimating the taxi estimate based on traversing a path through the decision tree using the request values until a node is reached, the node indicated the taxi estimate.

Abstract: A system and method predicts a taxi time for an aircraft. The method includes receiving historical flight information including a set of historical airspace conditions at a target airport. The method includes comparing real time flight information of a target aircraft to the historical flight information. The method includes identifying matched airspace conditions. The method includes determining historical taxi time information corresponding to the matched airspace conditions. The method includes determining a combined historical performance based on the matched airspace conditions and the historical taxi time information, the combined historical performance incorporating an interdependency between discrete characteristics of the matched airspace conditions and the historical taxi time information. The method includes determining an estimate for a taxi time duration for the aircraft based on the combined historical performance.
