As someone who lives nearby, I just don't see the need. Is there really enough traffic coming off of Westheights/Eastforest/Westforest?
There's reference in the display boards to an optional roundabout at each of the intersections: http://www.regionofwaterloo.ca/en/gettingAround/resources/5752-HighlandRoadImprovementsInfoSheet-Mar13.pdf
And I some more detail (albeit not much) in the presentation on pages 16/17: https://icreate3.esolutionsgroup.ca/230672_ROW_MUnicipal/en/gettingAround/resources/5752-HighlandRoadPCC2Displays.pdf
The only real reason I could see it being helpful is that the paint job on Westheights over the past few years is terrible. Old lines weren't fully removed before being repainted. People still drive in the bike lanes as if they were turning/passing lanes, and the painted lines make it seem like you're supposed to drive into oncoming traffic (especially the western arm of Westheights towards Driftwood.)
At rush hour, there seems to be less traffic flowing through than on Ira Needles, so roundabouts wouldn't get backed up as much. However, there would be more pedestrian activity along here meaning it might not be as safe for pedestrians as signalized intersections.
Thanks for the info. This one's kind of a no big deal for me. Not needed, not not needed.
RE: General Road and Highway Discussion - darts - 03-18-2017
maybe it is so the roundabout can accomodate larger trucks, buses, firetrucks.

There are plenty of options to allow this without making the circle larger. Mountable medians, lane straddling, and the like. Even then, I think we're still oversize. Trucks can maneuver through most of our roundabouts at near full speed without even straddling lane.
@timio Do you have any evidence that roundabouts are less safe for pedestrians. In fact, all the data I have suggests that they are more safe. And I'm not talking about comfort. I absolutely acknowledge that they are less comfortable to pedestrians (just as they are less comfortable for drivers), but in terms of actual risk of injury, I'd be very surprised if they were worse than signalized intersections.
@Spokes Needed or not is a question of value for sure, but out of curiosity, regardless of need, do you think they would be a bad thing? I'd prefer them, even if traffic flow or injury rates didn't necessitate them.

Sorry, I used the wrong phrase earlier. I agree that they are less dangerous, but more uncomfortable for pedestrians.
Drivers aren't necessarily used to expecting pedestrians at roundabouts, especially along Ira Needles where there's only residential on the one side. Along Highland, there's residential on both sides meaning the volume of pedestrians will likely be higher, although my experience is the traffic volume is lower.

My personal favorite comes to mind: Margaret & Union.
RE: General Road and Highway Discussion - jamincan - 03-18-2017
Do we have any examples of roundabouts with high pedestrian use? Off the top of my head, Laurelwood & Blue Beech Blvd (near SJAM) surely is, and I imagine the car traffic before and after school would also be fairly high.
RE: General Road and Highway Discussion - SammyOES2 - 03-18-2017
I think it's hard to judge pedestrian safety from KW roundabouts because most of them do seem to be in relatively light pedestrian areas. But googling around seems to agree that they're safer in general.
Also, I almost always see transports using both lanes of the roundabout. It actually irritates me because I feel like they often just pull into the 2nd lane without caring about other traffic - like they're owed both lanes right when they want it.

I'm not sure what you consider a "normal speed", but I've ridden down Ira Needles numerous times, and I've never seen them go substantially slower than traffic should be moving.
As for lane straddling, maybe it depends on their direction, I've seen them go straight through in one lane, I don't know about left turns, but even so, like I said, there are other options.
In fact, the Margaret and Union roundabout (which is only one lane) just proves that point. Yes, trucks go through there quite slowly on the rare occasion that they do, but there's nothing wrong with that. The important thing is that they still go through.

UK is full of roundabouts like this (image mirrored for driving on the right):
They fit in nearly any intersection, obstruct neither large vehicles nor vision, and cost approximately 15 minutes of paint crew next time they redo the lines.

By the chunks out of the hydro poles around the roundabout at Margaret and Union (https://www.google.ca/maps/@43.4672537,-80.4997936,3a,74.6y,186.94h,80.87t/data=!3m6!1e1!3m4!1spNqN0Xioy7ctGh1rSKOx6Q!2e0!7i13312!8i6656 and https://www.google.ca/maps/@43.467255,-80.4997175,3a,16.8y,165.13h,75.32t/data=!3m7!1e1!3m5!1st27M98pcT9Q_exehbulnfw!2e0!5s20110801T000000!7i13312!8i6656), it's clear some large vehicles have difficulty maneuvering this tighter roundabout.

Looking at that damage, I'm pretty sure it was some large truck making a right-hand turn, not negotiating the roundabout
RE: General Road and Highway Discussion - jwilliamson - 03-19-2017
The 8 bus will often make a left turn by turning over the centre.
RE: General Road and Highway Discussion - MidTowner - 03-19-2017
I was just going to point out that out- I would say the 8 routinely mounts the curb in the centre, sometimes even passing right over it. I have seen other larger (and other not-so-large) vehicles do the same.
It irks me that the centre is not landscaped. And that roundabout has been there for a while, but motorists who use it seem to generally not know that people on foot have the right of way. There are plenty of people on foot in that area.
