Abstract

We present a prototype version of a modelling and simulation system for envi- ronmental impact assessment in the field of traffic and logistics. This software system supports the user in modelling and simulating the environmental impact of various changes to traffic systems. Our approach integrates object-oriented modelling techniques with geographic information system (GIS) technology. The heart of the system is an extendable model base containing complementary and competitive models for the domain of transport and environment. 1 Introduction Information technology offers various opportunities for environmental impact assessment.^ A broad range of software systems for computer-supported envi- ronmental impact assessment have been developed, such as database systems for the management of
