Une méthode d'évaluation géolocalisée de l'insertion des projets routiers dans les territoires et de choix de variantes

A geo-located evaluation method for the integration of road projects in territories andthe choice of variantsBased on the advanced technique and science in the domains of the geographic informationand the social and environmental indicators, the objective of this thesis is to contribute to thedevelopment of a tool for helping the road variants identification and evaluation.The role of the construction design office in the road projects driving, its needs for a tooldevelopment and the pre-existent evaluation methods are presented at first.Then we study the automation possibilities for treatment the geographical data of the projectstudy area, allowing to highlight the most convenient zones for road section integration (basedon the ArcGIS software functions).To improve and go deeper in the variants evaluation and to help in the route selection, newindicators relative to global and local effects of the road sections, are proposed. They concernthe global environmental impacts from life cycle analysis type, the fragmentation ofecosystems, the safety of transport, the built heritage, the noise pollution, the co-visibility andthe radiance.Their applicability and their relevance are tested in road variant’s comparison of a realproject. To answer to the needs of the coordinating process, an interactive method ofindicators combination is proposed.Finally, the potentialities of development of these functions in the form of an operational toolfor the design office, are discussed.tel-00907595,version1-21Nov2013
