Mr. Michael Nolan:

I will address those. The Deputy asked about the cost of congestion. We carried out some studies in 2011 and 2012 but they are now somewhat out of date. It is very difficult to put a value on the cost of congestion because we do not know whether somebody who hops on and off is going to a bottle bank, work or a crèche. There is a mix. We have done calculations on the cost of an incident on the M50. An incident on the M50 causing a one-hour delay gives rise to a cost of the order of €200,000. It is quite significant. There were incidents to cause delays of two to three hours. That is a direct cost. It racks up quite quickly.
