Developing countries have been using the HDM-4 model since its release in 2000 for project or network level economic evaluations and on each HDM-4 application the analysts defined the vehicle fleet economic unit costs and the basic characteristics of the country. To present an order of magnitude of current unit road user costs in developing countries, the World Bank collected, during the first semester of 2006, the vehicle fleet economic unit costs and basic characteristics adopted on about 44 HDM-4 model applications done from 2000 to 2005 and performed a statistical analysis of typical unit road user costs, bringing all costs to 2005 US dollars.
The vehicle fleet economic unit costs and basic characteristics vary by country; therefore, this study made and effort to compute average global vehicle economic unit costs and basic characteristics for developing countries, as well regional averages for Latin America and Caribbean, Asia, Africa, and Eastern Europe and Former Soviet Union countries. With this input data, this study computed, using the World Bank’s HDM-4 Road User Costs Model (version 1.10), the following results: a) typical economic unit road user costs for paved roads on a flat terrain without congestion and with different roughness levels and b) typical road user costs composition for a paved road in good condition without congestion with roughness equal to 2.0 IRI, m/km.
