One of the fundamental urban transformations at South American level are the processes of transition between conurbations and metropolitan areas, where the promotion of mobility for a number of factors described in this article, produces and promotes new type of territorial dynamics. We can point out that today we face greater mobility for work and increasingly complex from the perspective of historical patterns of "workplace" versus "dormitory places", the contemporary reality mix them, producing asymmetries between the different territorial units. These territorial characteristics of socio-demographic, economic and physical proper (densities, building types, enabling network infrastructure, etc.) explain differences in commuting generated in the case of the metropolitan Valparaiso.
