VILLAS BOAS MELLO, José André. Polycentrality and mobility in the Metropolitan Region of Rio de Janeiro. Bitácora Urbano Territorial [online]. 2019, vol.29, n.3, pp.11-20. ISSN 0124-7913.  https://doi.org/10.15446/bitacora.v29n3.62420.

The work aims to evaluate the centralities in the Metropolitan Region of the State of Rio de Janeiro (RMRJ), based on the perspective projected in the study of J. Schnoor and the 2003 data of the Origin and Destination (OD) matrix. The analysis was based on the maps and data provided by the state transport department, containing the Urban Transport Master Plan (PDTU) of RMRJ. In order to define the lower and upper limits of the classes titled centrality axes, we used the Jenks optimization, a natural breaks data classification method, which uses an iterative algorithm that reduces the variance within the groups and maximizes the variance between the Different groups. The study made it possible to verify that the centralities of RMRJ are not concentrated. The analysis made it possible to verify that the displacement-centered centralities do not have a uniform morphological pattern, and the weaknesses in the connections between center and periphery confirm the monopolicentrality model proposed by A. Bertaud.
