Development of sustainable transportation systems : lessons from Curitiba, Brazil

Curitiba’s Integrated Transportation Network (ITN), in Brazil, has been highly regarded as a model of sustainable transportation for several years. Since its inception, the system has not only been molded to address the three core dimensions of sustainability –environmental, social and economic- but has also successfully brought together the government, the private sector and the general public. The purpose of this study is to describe the case of Curitiba’s planning process and transportation system. More specifically, this report first examines the conditions that led to a system to be well-regarded as sustainable and then determines some lessons learned that can guide the implementation of similar systems in other cities.
