Road design through a GIS: construction costs and enviromental costs
Abstract
The paper presents some suggestions for using Geographic Information Systems in road design. Two scenarios have been used to do this. First, roads have been traced after considering their construction cost, this taking into account topography, lithology, hidrography and the current road network. The second analysis further includes a taking into consideration of the cost to the environment. Both models produce an evaluing of existing road layout as well as a new surface casting. In either, surface costs are made patent and an automatic layout offering an optimun routing in terms of a low cost SIG produced. The area chosen for the exercisa is that corresponding to sheet 509 of the National Topographical Survey which represents the neighbourhood of Torrelaguna in the province of Madrid.
