Abstract
Congestion is a critical issue at most hub airports. This paper tackles this problem occurring at the airport with most passengers in Japan, i.e. Tokyo International Airport. This airport has four intersecting runways which nterfere with each other. Although the runway an aircraft uses is determined by its destination or departure airport to reduce air traffic controllers' (ATC) workload, this general rule can increase aircraft waiting time. To make runway operations more efficient, the runway operation is modeled by a queueing model, which calculates the average waiting time on each runway. The arrival traffic is optimized using the model, and it is shown that about 100 minutes of waiting time can be saved by appropriate runway allocation on a sample day.
