Mr. Peter Walsh:

Very few of our projects do not require an environmental impact report as they move through the planning process. As part of that report, extensive studies are undertaken and there are extensive projections and measurements of impacts. However, we do not reach the point of having definitive figures until we are at the point of submitting to An Bord Pleanála. It would take a significant amount of work to reach the point where you can have definitive numbers of that nature, but it can be done. Many factors will affect it. One of the reasons I mentioned traffic management plans was because, for us, once a road is bypassed, it is no longer a national road. The development of traffic management within the urban area that we bypass is not something we would normally oversee. We now have a requirement as part of the project to develop a traffic management plan, but I cannot be definitive on the question of whether it achieves what can be achieved in terms of the promotion of active travel, the reduction of trips and so forth because it may not be our project.
