    Probably for counting traffic for the roadwords on the Lucan Bypass

    They're just for monitoring traffic flow. They're on the M50 too. Basically the cameras take a picture of a vehicle and send it to the traffic monitoring control room of the relevant local authority. They can read the vehicle's registration number at one point and see how long it takes for that vehicle to pass another point. They can then gauge how quickly/slowly the traffic is moving and alter traffic lights manually if need be to improve flow.

    By the way, there are no lizards in Chapelizod. ;)

    could these be used for speed detection?

    They are not used in the day to day monitoring of traffic in order to manually make changes to traffic lights.

    they're going to be used for a system which is currently in use on the Naas Road which will let drivers know approximately how long it'll take to travel a certain distance (e.g. Leixlip to Newcastle Junction) by taking pictures of license plates and comparing them to pictures taken later.

    Least that's what I think it is anyway...

    Well, the same question was asked of a Dublin City Council traffic official on Newstalk 106 recently. The reply he gave was that which I posted above.

    They sound like an excellent idea; a much more accurate way of compiling traffic data than surveys where people answer from instinct. It never ceases to amaze me how reluctant this country is to harness camera based technology in relation to data collection and enforcement.

    Well the official would be wrong then

    The traffic cameras and scats are used to monitor and regulate traffic to and from the approaches to the M50

    Just been onto sdcc and according to 'traffic' there the system is a number plate recognition system to calculate travel times for their own records and not for the day to day management of traffic

    Its also a different technology to that being used on the Nass road
