An effective road transportation network is an important factor in economic and social development. It is also costly. Road construction and maintenance consume a large proportion of national budgets and the costs borne by the road-using public for vehicle operation and depreciation are even greater. It is therefore vitally important that policies be pursued which minimize total transport costs for the individual road links and for the road network as a whole. This requires the ability to quantify and predict performance and cost functions for analysis. HDM-III is designed to make comparative cost estimates and economic evaluations of different construction and maintenance options. The user can search for the alternative with the lowest discounted total cost and can call for rates of return, net present values or first-year benefits. Volume 1 organizes relationships as well as providing a road construction submodel with interacting sets of costs related to construction, maintenance and road use. Volume 2 provides guidance on the use of this model, including input data forms, inference ranges and default values and gives numerical examples.
