| Summary: | The standard cost-benefit analysis of transport infrastructure investment projects weighs a project's costs against users' benefits. This approach has been challenged on the grounds that it ignores wider economic impacts of such projects. At this International Transport Forum Round Table, leading academics and practitioners addressed these concerns and examined a range of potential approaches for evaluating wider impacts - negative as well as positive. They concluded that for smaller projects, it is better to focus on timely availability of results, even if this means forgoing sophisticated analysis of wider impacts. For larger projects or investment programs, customized analysis of these effects is more easily justifiable. Creating consistent appraisal procedures is a research priority
