Statistical correlations between the amount and form of land use changes and the location of new highways and wastewater facilities were established for four major metropolitan areas individually and in combination. The statistical findings were supplemented with results from a dynamic simulation model of land use in metropolitan Washington. The analyses identified factors which seemed to explain much of the variation in location and type of development in all four regions: availability of sewer service, proximity of an area to major highways, amount of vacant land, and residential vacancy rate. However, the relative importance of each factor varied from one region to another so that although results from pooled data were acceptable in terms of their aggregate statistical significance, the set of regression equations developed from pooled data cannot be expected to produce accurate predictions in all regions.
