This paper provides some initial results from a research project that aims to demonstrate how a system can be developed that exploits geographic information systems (GIS) to allow transport planners to routinely assess environmental effects. To explore the concept's practicality, the authors interviewed 20 practitioners. Typically, planners conduct travel forecasting on PCs with standard packages; they are interested in though not yet committed to GIS. They do require useful environmental information. Development of a MapBasic prototype application for MapInfo is detailed, tentatively called SMIRC (System for Modelling the Impacts of Roads on Communities). The paper justifies the selection of MapInfo. It describes the prototype's concept, software architecture, detailed design of programmed modules (ie the user-interface, network management functions and noise model), and possible future modules. Compared to other approaches, SMIRC: inputs forecasting data directly; is an add-on, not an integrated system; exploits `off-the-shelf' GIS; and emphasises modelling effects on sensitive land uses over effects from transport. These features appear to align with transport planners' needs and warrant further research. (A)
