Street Centrality and the Location of Economic Activities in Barcelona

The paper examines the geography of three street centrality indices and their correlations with various types of economic activities in Barcelona, Spain. The focus is on what type of street centrality (closeness, betweenness and straightness) is more closely associated with which type of economic activity (primary and secondary). Centralities are calculated purely on the street network by applying a multiple centrality assessment model and using a kernel density estimation method on both street centralities and economic activities to correlate them. Results indicate that street centralities are correlated with the location of economic activities and that the correlations are higher with secondary than primary activities. The research suggests that, in urban planning, central urban arterials should be conceived as the the cores, not borders, of neighbourhoods.
