Excerpt
The decision-making process for the development and maintenance of low-volume rural roads suffers from the lack of a customized economic evaluation tool. The World Bank?s Highway Design and Maintenance Standards Model (HDM-III) (1) and the forthcoming Highway Development and Management Model (HDM-4), being developed by the International Study of Highway Development and Management Tools, present a good framework for the economic evaluation of road investments and maintenance but are not particularly customized for low-volume roads (traffic less than 200 vehicles per day), do not capture all the benefits associated with rural road investments, and require a series of inputs which are impractical to collect for low traffic levels. Hence, the need for a simplified economic evaluation model to fulfill the planning and programming needs of highway agencies in charge of low-volume roads, without demanding input parameters that may be unrealistic and costly to collect while presenting the results in a practical and effective manner. This note presents the Roads Economic Decision Model (RED) that performs an economic evaluation of road investments and maintenance options customized to the characteristics of low-volume roads such as: ? high uncertainty of the assessment of traffic, road condition, and future -- maintenance of unpaved roads; -- ? periods during a year with disrupted passability; -- ? levels of service and corresponding road user costs defined not only -- through roughness; -- ? high potential to influence economic development; and -- ? beneficiaries other than motorized road users.
