Responsibility for traffic management in Dublin including responsibility for the management of traffic on the N4 is shared by a number of agencies, for example, the relevant local authorities, the National Roads Authority, the Department of the Environment and Local Government, the Dublin Transportation Office, the providers of public transport, as well as the Garda.
In so far as Garda element of traffic management on the N4 is concerned, I have brought the Deputy's concerns to the attention of the Garda authorities and I have requested a report on the matter. As soon as this report is to hand I will communicate further with the Deputy.
