Minimizing Shadow Area in Mountain Roads for Improving the Sustainability of Infrastructures

The lack of sunlight on mountain roads in the wintertime leads to an increase accidents. In this paper, a methodology is presented for use sunny and shady areas be included as parameter road design. inclusion allows design iterative method projected infrastructures. parameterization layout facilitates possibility applying process modifying geometric elements that constitute it, examining different alternatives until achieved which surface area minimized, increasing safety minimizing environmental impact. has been defined, generating analyzing results solar lighting study using file IFC format capable integrating with rest (platform, signaling, structures, etc.) thus obtaining BIM model viewed three dimensions moves towards 4D 5D. used was high located province Teruel (Spain). It section characterized by successive curves several traffic accidents have occurred due running off road, partly because presence ice platform.
