AbstractEndogenous nodal attractions are estimated using the general unconstrained gravity model for a 25-node US airline passenger database with known exogenous spatial interaction and impedance. A simplified algebraic method (SAM) is developed to derive satisfactory estimates for all nodal attractions and inter-nodal interactions with only a very small subset of the exogenous database. This method can be used for large-scale spatial interaction analyses in which obtaining a complete inter-nodal interaction matrix is impossible or a reduction of computation is necessary.
