Abstract
The article used as main hypothesis that the high interaction level among BCN cities and also with Brazilian territory could be a crucial factor to this region on achieving the Sustainable Development Goals (SDG) n° 11 goals. The polycentrism concept, Gravitational Model and flow of people by bus itinerary were used as research methodology. The results of estimators suggested that the Brazilian Center North has monocentric functional linkage, a framework that restricts the community cohesion and consequently, the capacity of this region to accomplish the SDG n°11 goals. In a conclusion, the Sub-regional centers A are strong candidates to boost the spatial interaction into BCN due to their social and economic relevance in this scenario.
