Estimation of Net Origin and Destination Passenger Flows of International Air Transportation

Abstract

In the international air passenger transport, OFOD statistics based on air tickets published by ICAO is generally used as O-D flows. However, since OFOD statistics counts transfer passengers twice, it is different from net O-D flows. This paper proposes the methodology to estimate the net O-D flows. Assuming route choice behavior and ticket type choice behavior of passengers, we estimate net O-D flows combining OFOD and TFS statistic. Applying this method to 10 metropolises in the world, we showed that about 30% discrepancy was found between OFOD statistics and estimated O-D flows.
