Estimates of Wider Economic Benefits (WEBs) are increasingly featuring in cost-benefit analyses (CBAs) of major urban transport infrastructure projects. Governments are particularly interested in WEBs because they relate to productivity. The parameters used to estimate WEBs in Australia to date have been estimated using methodologies that are inconsistent and not in line with international best-practice. Thus the reliability and comparability of WEBs estimates in Australian CBAs is questionable. The report proposes a way to develop a robust set of parameters for practitioners to use when estimating WEBs.

The report was commissioned by BITRE on behalf of Steering Committee oversighting the Review of the National Guidelines for Transport System Management. If a robust set of parameters can be developed, it will be published in the Guidelines. BITRE engaged consultants KPMG to undertake the task.
