Caractérisation des tissus urbains à partir de l’analyse structurelle des réseaux viaires

Street networks shape the urban layout that structures the city spaces and delineates homogeneous urban areas. We focus on the study of urban morphology from a structural analysis of the streets’ network. The work on a geographic model allows formalizing mathematically the street network by using gr...
