This paper provides a description of how decisions regarding transportation programs and project can be made in the context of sustainable transportation. It is shown how to identify appropriate performance measures for sustainable transportation. The identified performance measures were then quantified with a traffic simulation model (CORSIM) as well as transportation environmental models. These quantified measures could then be used as input into the newly developed index for sustainable transportation. The index was developed at the individual level and at the aggregate level and provides an indication of the relative sustainability. It was shown that the index could be used for a base case as well as a future year scenario. It was also shown that the methodology could be used to make decisions regarding transportation projects and that these decisions are different to ones that only consider the net present worth in monetary terms. The test beds used for this study comprised of transportation corridors in South Africa and the United States. It was shown how the methodology can be developed and applied for transportation corridors across functional classifications, modes, overall goals, and even nations.
