Abstract
Overview of a 12 million dollar Brazil Ministry of Transport and United Nations Development Program supported research study aimed at determining relationships between vehicle user costs, roadway design standards and maintenance policies for low volume roads. The relationships are based on an analysis of data generated in a survey of vehicle users operating on over 60,000 km of homogeneous paved and unpaved routes that has produced up to two year of user costs data on over 1200 vehicles, together with 450,000 observations based on radar speed measurements of vehicle behavior in Brazil plus fuel measurements from nine project test vehicles. Finally, data developed from 187 paved and unpaved roadway test sections is being used to develop equation to predict road performance. All of the relationships are being incorporated into a computer based planning model to be used for evaluating alternative highway transportation strategies. /Authors/
