A systems approach to the evaluation of proposed limits for vehicles using Australian roads

Stewart, S. R. / Tait, S. L. / Prince, P. S.

The authors describe a predictive road model to investigate changes in mass limits for vehicles using Australian roads. The model can be used to research variations in roads policy including assessing road standards, road funding strategies, pavement loading and vehicle operations.

The model has been used to predict the effects of possible changes to road vehicle limits in Australia and to determine the most acceptable set of limits on the basis of economic analysis within the National Association of Australian State Road Authorities (NAASRA) Review of Road Vehicle Limits Study.

The model could be developed and applied to investigate the effects of other changes in road and bridge loading resulting from changes in policy or practice which would affect the commercial vehicle fleet. An example of this type of application is the assessment of separable costs between vehicle categories and road types.
