Territorial planning Landscape: Landscaping Approach in infrastructures design

During the recent decades the urn ban human settlements, either through extenn sion of their physical and structural boundaries or through the influence of ecological footprint in their adjacent pristine natural areas, are den stroying and demolishing these intact natural areas more rapidly than the past. The foremost example of it would be the road transport netn works. Such projects with infrastructural funcn tions in natural territories are currently a sign nificant proportion of designs that are planned and projected by landscape architects; it has provided an opportunity to create a complen mentary landscaping for both the projects and nature. In other words, the landscape approach based on the common language of landscape project in human territorial involvement is an effective strategy in creating a harmonious combination of functional and technical ren quirements of the project with site potentials and achieving sustainable development. In European countries and specially France, the road transport networks have high opportunin ties for development due to its appropriate clin mate and specific ecosystem. There exist three main approaches in management of transporn tation infrastructure development which are the Sustainable Design, Improving Life Quality and Steady Growth. Therefore, during the previn ous two decades the associated operation and management organizations try to arrange their special policies by assigning these projects to landscape architects to achieve an ecological sustainable development. The grand project of A20 Auto route, done by Allain Provost and Allain Cousseran together, that is one of the roads connecting the north to the south of France, is the best example of this particular design. This project has been widely admired for being a nature – oriented pass with intricate topography and specific biology, which had been the most important challenge, as well as unitized and intelligent combination of ecological and natural approaches to provide functional protection and optimization. The sculptural earthwork in the land biology using geometric hierarchy and scale reading in comn bination with the appropriate vegetation pron vides the aesthetic aspects with the ecological contextualism. The project attempts to adjust the visual boundaries and the nature to minin mize the contrast between the natural environn ment and pristine lands. Such approaches in spatial organization have converted a connectn ing road that splits the natural territories into pieces by its self-indicated lines to harmonic intervention in the natural ecosystem. To wit, landscape approach to development infran structures has provided the chance to accomn plish human settlement influence on natural and ecological territories in a sustainable way maintaining biodiversity.
