This paper describes the advanced development, at Griffith University, of a GIS-based system that combines outputs from transport scenario testing methods with land use information for modelling the environmental impacts from road traffic. This system, known as "the TRansport Add-on Environmental Modelling System (TRAEMS)" was developed using MapInfo GIS and is intended for use by transport planners as an add-on module to existing transport planning models. The model incorporates environmental factors such as noise, air pollution, energy consumption and pollution in stormwater runoff in a system that will fit almost seamlessly onto the current range of transport models in use. By incorporating these factors into a user-friendly computer package, the transport planning process and environmental implications can be considered simultaneously, creating the potential for a more efficient and environmentally sensitive planning process. The outputs from the system provide planners with immediate information on the environmental effects of any transport proposal being considered and thereby aid in the selection of a preferred alternative. This paper reports progress in the development of the noise, air pollution and water quality modules of this system and demonstrates the maximum utility of this form of modelling in the testing of transport planning scenarios.
