Decision Support Systems for Environmental Impact Assessmnet of Transport Infrastructures

Abstract Decision Support Systems for Environmental Impact Assessment of transport infrastructures are considered in this paper. Some indications which should be followed in practical applications are pointed out and SILVIA , a Decision Support System, is presented. SILVIA covers the four parts of an Environmental Impact Assessment study: the preparatory or orientation phase, the land analysis phase, the impacts estimate phase, the decision phase. Finally, two directions for further developments are focused: sensitivity analysis and group decision.
