EM Algorithm for Mixed Hazard Model for the Road Traffic Exiting from Airport

Abstract

Road traffic exiting from airport can be modeled by a mixed hazard model, where each hazard function corresponds to the passengers from arrival flight. This paper proposes an iterative estimation procedure for the model based on the theory of EM (Expectation-Maximization) Algorithm. The procedure is applied to the traffic data of four weeks at Sendai Airport, where new railway access line were introduced on March, 18th, 2007. The results shows that arrival passengers by daytime flights do not use railway as much as the morning or evening flyers, possibly depending on their travel purpose.
