This article reviews methodologies used in the estimation of costs imposed by externalities produced on the movement of people and freight. The focus is on freight transport by truck, although the methods selected may be extended to other modes. The determinants of externalities and their associated costs are identified, particularly those caused by air pollution, noise, accidents, and use of infrastructure. The relevance and requirements for the application of these measurements in the Brazilian context are also discussed.
