PUTTING THE ECONOMICS BACK INTO EVALUATION: SOME INSIGHTS INTO THE EVALUATION OF URBAN ROAD PROJECTS. 14TH AUSTRALIAN TRANSPORT RESEARCH FORUM, PERTH 20-22 SEPTEMBER 1989; FORUM PAPERS. VOLUMES 1 AND 2

Urban road projects can have substantial impacts on travel in addition to rerouting of existing trips. Economic evaluation of such projects often fails to recognise the complexity of those impacts, despite the theoretical basis for doing so being well established. A practical methodology to bridge the gap between economic theory and current practice is described and applied to a major urban road project. Estimated benefits were around half the level with the simple resource cost differential model, with further variations of 10-15 per cent each from additional refinements. The paper also identifies problems relating to traffic growth forecasting and user perception of costs, which should be addressed (a). For the covering record of the forum, see IRRD no 822808.
