Abstract
The importance of urban form in the quest for sustainable development has been recognised in a number of countries in recent years. However, there has been limited progress in bringing environmental planning into the sphere of urban systems planning. This situation can be largely attributed to the absence of advanced integrated land-use-transport-environment modelling tools capable of analysing the behaviour of complex, dynamic systems. This paper describes STEAM, Excel modules for integrating land-use, transport and airshed models for evaluating the effect of city form on air quality. STEAM contains models for calculating network congestion and link emissions. Some results from a preliminary application in Melbourne are presented. (A)
