Reverse gravity model based on OD traffic flow of air passengers

To estimate passenger traffic at airports based on air passenger OD (origin-destination) traffic flows and air route distances, a simplified algebraic algorithm was proposed with the help of Hamiltonian graphs. The parameters in the reverse gravity model were calibrated with the statistic data of 15 major airports in China. The simplified algebraic algorithm and conventional algebraic algorithm were used to calculate the passenger traffic of 15 airports. Their results are reasonably consistent. Compared with the conventional algebraic algorithm, the simplified one needs only a smaller number of data, and it is especially suitable for large-scale OD matrix analyses without compete inter-airport data.
