I think in general most Monctonians are fairly accepting of roundabouts (within reason)
We have a long history with roundabouts if you include the Dieppe and Causeway traffic circles.
The five point roundabout they put in at Killam/Collishaw about 7-8 years ago fixed a major traffic headache.
The double lane dogbone roundabout at Harrisville/Dieppe Blvd & Highway 15 however has been less successful. Multilane roundabouts can be confusing, and, the dogbone handles a lot of 18 wheelers, and these trucks require both lanes to navigate the turns (tight radius). In addition, there are heavy traffic volumes meaning there can be considerable line-ups waiting to gain acces to the roundabout at peak times.
Smaller single lane roundabouts are generally not an issue, but, I find that roundabouts are not necessarily pedestrian friendly.
Roundabouts are fine, just so long as there is some sober thought given to whether or not a roundabout is truly a good idea at any given intersection.
"a rondabout if necessary, but, not necessarily a roundabout."
