Gardaí and music promoter MCD are appealing to people attending the One Direction concerts in Croke Park later this month not to queue early.
A briefing to outline the safety and security measures for the concerts along with the Garda traffic management plan took place in Croke Park this morning.
The boyband is due to play for three nights beginning on 23 May.
The event controller for MCD, Eamon Fox, said early queuing before 5pm will not be allowed.
He said a new system of "tag-a-kid" will be used for the concerts for the first time whereby adults or guardians can write their seat number and phone numbers on wrist bands in case they get separated from their children.
Superintendent Kevin Gralton from the Mountjoy Garda District encouraged people to use public transport and said there will be two designated parent pick-up areas.
Superintendent Gralton said there will be around 200 gardaí involved in policing the event.
