Mr. Michael Nolan:

There is a range of projects that we have submitted to the Department. We do not just look at the benefit-costs ratios or BCRs. We have a national transport model and we predict congestion levels over the coming years based on that model. This would be an indicator of what schemes we would choose. There are also severe bottlenecks on the network that we try to address. Another thing that we look at carefully is completing the missing links or connections on the network to maximise the return on existing investment.
