A NEW APPROACH FOR THE IDENTIFICATION OF ENVIRONMENTAL-ISSUES AT STAKE IN A ROAD PROJECT

The concept of considering environmental stakes in engineering project s has gained more and more credence in recent times, mainly because of new regulations. An approach that is aimed at identifying environment al issues at stake in a road project is proposed. First, all elements highly affected by the project are determined using a cause-effect net work. This type of identification is based on three components: action s undertaken, environmental characteristics and the stages of the proj ect. Then, an expert evaluation is carried out using a multicriteria p rocedure followed by a public evaluation, in order to take into accoun t the significance that individuals may give to each environmental com ponent. Finally, these two independent evaluations are aggregated toge ther. The entire process is integrated in a knowledge-based system. (C ) 1995 Academic Press Limited
