Description :
A new measure of urban centrality is introduced. The proposed index constitutes an extension to the spatial separation index. Urban structure should be more accurately analyzed when considering a centrality scale than when considering a binary variable. The proposed index controls for differences in size and shape of the geographic areas for which data are available, and can be calculated using different variables such as employment and population densities, or trip generation rates. The index is applied to the urban structure of four metropolitan areas: Pittsburgh, Los Angeles, São Paulo and Paris. It is compared with other traditional spatial agglomeration measures, such as global and local Moran's I, and density gradient estimations.
