According to this perspective, the financial earnings resulting from the implementation of transport infrastructure can be captured for its own investment. Given the restrictions of society indebtedness, due to social inequalities, scarcity of resources and insufficient fare collection, with the current financial model for public transport infrastructures, the value capture configures as a strategy to be explored to obtain resources. This paper presents the concept of value capture and its connection and relevance with transport infrastructure financing strategies. Applied to the evaluation of the impacts on the surrounding regions of one of the most significant Brazilian transport projects, the improvement and expansion of Belo Horizonte＇s metro, the provided value capture outcomes open more realistic perspectives for greater engagement of the Public Sector in such projects.展开更多
