I think I have something on this thread already but I would use the junction at briarhill fairly regularily (usually accessing it from both sides of the monivea road)
I do think that at rush hour the people on the dual carriageway and entering parkmore etc are definetly better off than with the roundabout. Even coming out of parkmore is probably better off as well. In general, at peak times I reckon most drivers are better off. Off peak the lights will hold you up, but not for too long. The sequences seem pretty good tbh.
I think there will be less accidents in the long run, but any accidents may be more serious than those that happened at the roundabouts.
I can only assume there will be similiar stories at the two new junctions as it does make sense that in theory signal controlled should work better however it might take a few weeks to get things right.
The next 6 weeks are going to test the three new signalised junctions and the seamus quirke road junctions but without the entire dual carriage way (including the quincentennial and headford road roundabouts changed to signalised junctions) signalised there are still major bottlenecks.
