Verification tests of residence-location models
The advancement of knowledge in the sciences typically follows a continuing cycle of theory development and theory verification. This chapter describes a empirical verification of the residence–location model. Reasonable assertions about the effects of any individual variable on the residence–location behavior of a resident of a particular income group for a given zone may be given; yet, when all the variables operate together, then individual effects may be obfuscated by their interaction effects. Despite all these difficulties, the general model structure showed a remarkable ability to describe the spatial patterns of residences in these many urban areas. It may also be possible that the aggregation problem which separates micromodels of residence–location decision-making from macrodescriptive models such as the one tested is insurmountable. Another way of saying this is that some regions are either insensitive to congestion, or simply never develop enough congestion to make any difference to their tripmakers and their location decisions.
