AB - We develop a novel dynamical method to examine spatial interaction models(SIMs). For each SIM, we use our dynamical framework to model emigrationpatterns. We look at the resulting population distributions to see if they arerealistic or not. We use the US census data from 2010 and various spatialstatistics to access the success or failure of each model. While we looked atover eighty different SIMs, we will focus here on two examples: the productionconstrained gravity model and the Radiation model. The results suggest that allthese models fail to produce realistic population distributions and we identifythe flaws within existing models. This leads us to suggest that we shoulddefine site attractiveness in terms of a second short range SIM leading to anew spatial interaction model - the Two-Trip model - which offers significantimprovements when examined via our method. We also note that our Two-Tripadaptation can be used in any spatial modelling contexts, not just emigration.
