Throughout the world, the use of some kind of a formal transportation project evaluation procedure is a requirement. Yet, by and large, these are partial; in fact, much weight is often placed on the initial -pre-engineering -phases of the planning process, when vital information, such as accurate costs and demand projections, is largely missing. Moreover, many of these procedures neglect to consider key issues such as project’s risks, capital costs financing, latent demand, market imperfections, labor force availability and various incompatibilities between trip rates, travel times and activity location. As a result, projects, which are judged as viable under such deficient evaluation schemes, may have had a significantly different projection of capital costs and demand should a well-founded, thorough, and efficient evaluation process be used.
