In this paper, TOPAZ (Technique for the Optimum Placement of Activities in Zones) a mathematical programming technique is used to study long term effects of transportation systems on macro development patterns in urban and regional systems: for a Melbourne-Sydney regional corridor; and for the small town of Blacksburg in the United States. The first case is an objective function representing total costs and benefits for several alternative decentralized layouts of land uses and public service facilities. A gravity model is used to predict daily travel between town zones, and an iterative procedure produces the cheapest solution within certain constraints. In the second application, sub-models representing fuel consumption and pollution levels are added to the objective function, to ensure that they are reduced to a minimum. From these two studies, it can be concluded that the transportation, land use development, energy and air pollution components of urban and regional systems are highly interconnected.
