The development of equations to predict vehicle operating costs was a major objective of recently concluded research into the interrelationships among road construction, maintenance, and utilization in Brazil. A selection of user cost equations determined from survey data analyses is reported. Cost data were collected on 1675 vehicles, which were operated by 147 companies, 75 of which were owner-drivers. Highway characteristics of the routes used by these vehicles were measured by two specially instrumented cars. The equations obtained in Brazil allow costs to be predicted for the full range of vehicles currently operating on Brazilian low-volume highways. Attention is restricted to cars, buses, and medium and heavy trucks to facilitate comparisons with other studies of vehicle operating costs. Predictions for maintenance parts and labor costs, tire consumption, and the change in a vehicle's value over time are addressed. A novel feature of the analysis reported here is that estimation was carried out in the context of an error components model for vehicle operating costs. The effect of road geometry, surface condition, and vehicle age on operating costs receives comment. Estimates of total costs provided by the survey equations for buses and trucks are compared with the prevailing rates and tariffs for these vehicles. The Brazilian results are comprehensive and complement the research carried out in Kenya, the Caribbean, and India.
