Brazilian megacities: quantifying the impacts of the Brazilian urban mobility policy

Brazil has several problems related to urban mobility. These issues are most evident in big cities where the territorial extension and the complex activities developed in urban space make transportation planning difficult. Therefore, Brazilian cities face challenges to implement the Brazilian Urban Mobility Policy (BUMP) requirements. Since this enactment, in 2012, several studies have been developed to evaluate the impacts of the mitigations proposed by this law. Among these studies, a proposition of a system dynamics (SD) model to assess the effects of this policy stands out. This model allows verifying the impact of different BUMP mitigation measures (individually and together). Therefore, this paper aims to obtain and to compare the results of the application of this SD model in two Brazilian megacities: Rio de Janeiro and São Paulo. The results show the importance of BUMP implementation to reduce the negative externalities of transportation systems and improve their efficiency. However, the effects of this policy are not the same for the two megacities.
