- W2245983644 abstract "Several published research reports have shown that vehicle fuel consumption increases as pavement roughness increases. The existence of such a relation is today of particular interest to state departments of transportation for use in cost-benefit analysis of potential highway improvement projects. For a variety of reasons, however, the results of the earlier studies are not readily usable in benefit calculations. Therefore, in 1980 the Wisconsin Department of Transportation conducted a local field study that sought to define, for practical application, the relation between automobile fuel consumption and pavement roughness. Three different automobiles traveled on five pavement sections that, collectively, represented a wide range of roughness. For these pavements, roughness was expressed in terms of serviceability index, as measured by Wisconsin's electronic road meter. Fuel consumption was measured by a specially designed fuel meter mounted in each test vehicle. To minimize the influence of variables other than pavement roughness on fuel consumption, test conditions and procedures were highly controlled. The collected data suggest that there is in fact a quantifiable, but very modest, increase in automobile fuel consumption as pavement roughness increases. Over the range of roughness typically associated with state trunk highways (serviceability values between 1.5 and 4.5), this increase was (a) about 1.5 percent, (b) linear, and (c) not related to vehicle size. For the entire range of roughness included in this study (serviceability values between 0.9 and 4.4), the increase in fuel consumption was about 3.0 percent, which suggests that the overall relation between fuel consumption and pavement roughness may be nonlinear.
