De la accesibilidad a la funcionalidad del territorio: una nueva dimensión para entender la estructura urbano-residencial de las áreas metropolitanas de Santiago (Chile) y Barcelona (España)

Abstract

One of the most important elements in the development of discontinuous urban systems is accessibility; nonetheless, this concept has been limited to indicator based on time, distance and cost in order to go from one point to another inside the urban system. Accessibility is not only determined by transport networks, but mainly by mobility, a physical reflection of peoples will to move across city. This investigation proposes an alternative way to compute accessibility, called urban functionality. This indicator is based on mobility analysis, and so on the social nature of accessibility. To prove the efficiency of urban functionality to explain residential distribution, two metropolitan areas were studied: Barcelona and Santiago de Chile. The results suggest that urban functionality has a better capacity to explain than traditional methods based on time and distance. In addition, it can be observed that non mandatory mobility has a more rigid demand if it's compared to obligatory mobility (i. e. travel-to-work). Barcelona is more rigid on mobility if is compared with Santiago
