Mr. Con O'Donohue:

Every single van is based in a zone where we have identified clusters of collisions. No other factor is taken into account in deciding where GoSafe vans go other than the collisions. We identify the cluster of collisions on the road, we identify a stretch of road that is 2 km, 3 km, or 5 km long and then with GoSafe we select a site to carry out the enforcement. It is the history of fatal and serious injury collisions that determine where they go. We then deploy the vans there based on the times of the day and the days of the week when the collisions occurred. We match it up.

GoSafe has key performance indicators it has to achieve and we give them some latitude in terms of time. It cannot give exactly 15% of its time to a particular location so we will say we want between 12% and 18% of its time. We give them some latitude either side of 15%. It stays between the lines all the time in terms of the days of the week and the times of the day. It is very much strategic in terms of enforcement. It has reduced the deaths by 50% in the zones. In some years we are talking about saving 22, 26 or 28 lives a year. That is the figure we are looking at for recent years based on the halving of deaths, or less than that, in some of the zones.
