به سوی یک رویکرد توسعه پایدار در ارزیابی حمل و نقل

Transport project assessment, starting from a classical socio-economic approach using cost benefit analysis, has progressively taken into account environmental concerns, both through external cost estimates used in socio-economic indicators and through environmental studies, which havebecome compulsory in many countries as is the case in the European Union. The purpose of this paper is to analyse in what directions the transport assessment system could go in order to be more in line with a sustainable development (SD) approach. After a discussion on selected key characteristics of SD as guides for the analysis, we analyse the existing situation and its current developments as illustrated by a French case, and try to see what would be missing with regard to the key characteristics identified. Finally, ideas for a new approach in project assessment are discussed, covering the assessment process, its contents, and its links with project design, from a SD point of view.
