For various reasons, it may be necessary to design a section of highway with substandard values for some elements. Such design exceptions require appropriate assessment and justification of the potential impacts to highway safety and operations. It is necessary to conduct economic analyses for proposed design exception projects to compare with the standard designed projects. An economic analysis method was developed to conduct benefit-cost evaluations for design exception highway projects. The method considers life-cycle-costs as well as life-cycle-benefits resulting from a proposed built proj...
