Cost-benefit analysis (CBA) is the most widely used tool for appraisal of transportation
infrastructure projects, but there isn’t generalize guidelines about its implementation, there
can be found different approaches that suit the perspectives of each evaluating entity. This
document, it shows three different guidelines that used in practice for transportation
infrastructure projects, in which there are some different costs and benefits considered
informing decision makers about the project appraisal. The costs and benefits with market
values have been the predominant ones in the CBA, but there is a transition to use without
market values, however, there are no generalized methodologies, so more research will be
needed.
