ADAPTING THE BRAZIL AND WORLD BANK RESEARCH ON ROAD USER COSTS AND PAVEMENT DETERIORATION TO CANADIAN NEEDS AND CONDITIONS

A large scale project was carried out in Brazil to determine the effects of highway geometry and pavement roughness on vehicle operating costs. The data collected in this study was incorporated into a life cycle investment model called hdm3, developed by the World Bank. This model can be calibrated to local conditions for individual feasibility investment studies and for transport network policy studies. In 1987, the roads and transportation association of Canada undertook a study to examine the world bank model and review its applicability to Canadian conditions. Results suggest that calibration and adaptation of certain components, notably maintenance and depreciation costs, is necessary before the model can be applied to conditions in Canada. However, the world bank's pavement deterioration model will be useful for Canada since it can account for environmental roughness progression instead of being solely dependent on traffic loadings. With calibration to local conditions, the model could be used by transportation agencies as a tool to help determine the optimal capital and maintenance expenditures on highway transportation.
