This report pertains to a research program whose goal is to formulate a methodology to predict air pollutant emissions resulting from the construction and operation of two types of major land use projects, large residential projects and large concentrations of employment (i.e., office parks and industrial parks). Emissions are quantified from the major project, from land use induced by the major project, from secondary activity occurring off-site (i.e., generation of electricity by utilities), and from motor vehicle traffic associated with both the major project and its induced land uses. Volume one documents the development of a model to predict the induced land use from such major projects. It discusses the theoretical basis of the model, the specification of equations that model the theory, and the causal analysis of the equations. Sample selection and data collection are also discussed.
