Revelando las centralidades del transporte público mediante SIG y GTFS: una propuesta de reequilibrio urbano para el Área Metropolitana de Barcelona

Abstract

This paper is devoted to establishing the degree of accessibility-based centrality of the urban structure conferred by public transit at the Metropolitan Area of Barcelona. Additionally, the strengthening of certain railway hubs is considered, with a view towards rebalancing the whole urban system. A landscape of accessibility is revealed, assuming that opportunities are the same everywhere, by evaluating de total distance from each place to all others. The impedances are based on GTFS (General Transit Feed Specification), while the results are displayed via isochrones. The results show the metropolitan space-time cartography, whereas the proposal of increasing intermediacy allows for a better integration of strategic places and corridors.
