Dynamic speed limits are set to be introduced on the M50!

    Apologies if a thread already exists, I find the thread search function very user-unfriendly.

    New dynamic speed limits are set to be introduced on the M50 which can be raised or lowered as operators see fit, ie, during accidents, heavy traffic or any other incidents. This is wonderful news and will hopefully actually decrease overall journey times and reduce the accordion effect. Thankfully I rarely have to use the M50 and I never use it for commuting.

    One worry I have is that a person might be a diligent observer of speed limits and the limit changes just as the person passes the sign and the Gardaí catch those people out between the sign that just changed and the next visible sign.

    Hopefully these will be rigidly enforced with average speed cameras, unless everyone else is on board, the new concept will be redundant.

    Too many people don't know or don't follow motorway rules anyway so I don't see this being any different.

    Weren't these proposed to be introduced about 5 years ago too?

    I think they are being implemented now though. They need to be coupled with average speed cameras though, otherwise it's useless.

    The M50 isn't that long a stretch, 45 km if memory serves. If people rigidly stuck to 60 km/h during rush hours, then you would have a GUARANTEED 45 minute journey from where it begins at the end of the port tunnel to Bray.

    No one seems to follow these on UK motorways, says there’s a lane closure and they’ve dropped the limit to 50, people will tail gate you and flash you if you stick to the limit. Even when there’s signs for cameras. People seem to think it’s their god given right to go at 70/120 on the motorway.

    Sums it up really- add in no Garda enforcement and your back to square one- roads policing here isn’t taken seriously.

    there are new digital signs being erected between the ballmun and blanchardstown exits, i presume they're the first of these being installed.

    These signs have been testing recently. From what I read elsewhere they will be introduced on the blancharstown section first and more areas later.

    Initially there will be no law against breaking the suggested speed but later like January 2022, it will be an offence to break the speed.

    There does not seem to be any plan to install average speed cameras. In the last 1 year mobile speed camera vans are regularly near the toll bridge and dundrum. Presumably these will continue and enforce the variable limit

    As suggested lots of people will ignore the speeds, and enforcement will be rare. Hopefully they will show a big X when s lane is blocked to encourage people to not use it and move over to unblocked lanes before they reach the crash. The intention is to speed up average trip times at peak rush hours and during accidents, by preventing stop, go, but I really think average speed cameras will be needed to make this happen. At the moment the old signs just say crash ahead, but don't tell you which lane to use, which is a bit pointless.

    That apparently is the busiest stretch of the M50.
