How common are traffic circles (roundabouts) in your area? Post pics if you have any.

Not common enough in Northern VA. The few we have work fine. The more, the better.
Here's a KMZ file of 5,125 roundabouts in America (doesn't include traffic circles or neighborhood circles with small diameters).

Are we referring to circles, rotaries (as they say in Massachusetts), and roundabouts?
If non-roundabouts count, I live less than 10 minutes away from the death trap known as the Somerville Circle (https://www.google.com/maps/@40.5747549,-74.6286846,3a,48.7y,332.01h,91.07t/data=!3m7!1e1!3m5!1sDZ46deUHJDmG_2y2St1Nwg!2e0!6s%2F%2Fgeo0.ggpht.com%2Fcbk%3Fpanoid%3DDZ46deUHJDmG_2y2St1Nwg%26output%3Dthumbnail%26cb_client%3Dsearch.TACTILE.gps%26thumb%3D2%26w%3D392%26h%3D106%26yaw%3D323.729%26pitch%3D0!7i13312!8i6656?hl=en).

FTFY. Let us know, by the way, if roundabouts are too technically difficult to negotiate.
None yet, though we're getting one next year as part of a bridge reconstruction project for some really dumb reason.
I hate those stupid things and wish they'd go die in a fire.
Our unincorporated community got the first roundabout in this county at an active intersection --- as opposed to a partially built-out development --- about a year ago. It's an intersection (formerly a two-way stop), by the way, that I hated to navigate in the direction requiring me to turn left. I often told my wife, "This is a good location for a roundabout!" She'll roll her eyes and confirm this.
It was strongly opposed in the local paper, and since its opening there has been almost no griping. I like going through it. Most local residents seem to have figured it out.
Properly sited and designed, roundabouts can be a good traffic control option. There, I said it. I know of two or three other locations where they would be preferable to the current two-way stop.

Many people in the heartland are very resistant to change of any sort. They also travel abroad less and hence don't have the chance to see them in action (and have only seen Chevy Chase's European Vacation)

Help me HB. Perhaps it's being 1/3 of your age, but I think the roundabout is the best European import of the last quarter century.
New Brunswick has it's fair share, and have been implemented more and more. Properly-placed, they are great.
This huge (mostly) roundabout is starting to see it's limits tested sadly, but in general seems to work considering the marshy terrain limits bridges and the large amount of traffic using it.
https://goo.gl/maps/FrzHRAuakr42
This roundabout is another prime location for one, and with current traffic levels it's easy to merge in.
https://goo.gl/maps/EpYBL3mY5xm
Of course drivers here have been exposed to them long enough (first example dates from around 1972 IIRC, and the second has been there since at least 1997)
Fresh roundabout that replaced a 4-legged traffic signal that didn't line up to Purdy (and by extension Mapleton, which is an important road), instead it used to line up with Waverley, and drivers had to cut across to continue going on Collishaw (another important road going into an industrial area). The roundabout here has eased traffic moving Collishaw->Purdy/Mapleton without impacting Killam Dr traffic too much.
https://goo.gl/maps/Zj1tTXK1bs22
This one is poorly designed, and seemed to have been built too "east" the result is that the roads don't quite match up (particularly turning "left" from Gateway Dr. can be tricky). The other two roundabouts NE on Miramichi Rd are much better. They were put up sometime before 2006.

Nope. I don't like them, mostly because I think people don't know how to use them well here, due to lack of training, practise or otherwise. That being said, they can work better than 4 way stops depending on the intersection (four way stops with more than one lane, which are most of them). I know many former traffic lights/four ways stops that have been converted to traffic circles in different locations. Some work pretty well, while others I feel are waiting to cause an accident.
To answer the OP, there are some roundabouts in Winnipeg, several just south of my house in a new housing development.
Speaking of roundabouts, how often are these used? https://goo.gl/maps/iQfJJwdhKxM2
They're not really traffic circles, but I don't know what to call them. I've only seen them here, and nowhere else I've lived.

It sounds like your beef isn't with the facility, but rather with the drivers who can't use them properly.

That's about right. I think they would work better if people knew how to use them properly. People, including myself, have limited experience knowing when to yield, when to proceed, which lanes are for what etc.

Here is one of the many roundabouts constructed as part of the I-41 project in Green Bay, WI. This roundabout is for Wis 29 local traffic, while a directional T interchange above is a free flow connection for regional traffic between I-41 and Wis 29. The bridge pier in the center is for one of the flyover ramps. There are over 60 roundabouts in the Green Bay area with new ones being constructed each year.

Below is a roundabout from I-41 South to Shawano Ave. The roundabout is 3 lanes. Many of the roundabouts around Green Bay are multilane with 2 or 3 lanes.

I'm pretty convinced many newspaper comment complainers have never left their own state...or even their own town...acting as if whatever is being proposed is the stupidest, dumbest thing ever imagined.
Here's a map of roundabouts in the lower 48:

The high crash rates at multi-lane roundabouts (especially 2x2 roundabouts) are well documented. There were several presentations discussing this issue at the TRB's 4th Annual International Conference on Roundabouts:

This one caught my eye...I happened to scroll around and saw a stop sign. I soon realized that last year, this had a small circle in the middle with stop signs on approach at all angles. They reconstructed it with a larger center circle, and made it into a true roundabout. Nice.

It looked like the former design had stop signs on all 4 legs entering the circle. Wonder how long it was like that.

Even though they may be consistent, Wisconsin roundabouts have seen a 12% increase in total crashes and a 38% reduction in injury crashes. This is a lot worse than the national numbers that show a 40% reduction in total crashes and an 80% reduction in injury crashes. Andrea Bill touches on these statistics in her TRB presentation:

OK, but keep in mind the majority of the roundabouts studied in the Wisconsin study are simple multi-lane (1x2) roundabouts. The roundabouts with the worst performance are the 2x2 multi-lane roundabouts. In fact, the only 2x2 roundabout analyzed in the Wisconsin study in DePere was one of the the worst performing in the study and was re-striped as a 1x2 roundabout shortly after the safety analysis.
So basically, the simple 1x2 multi-lane roundabouts are crash prone. The 2x2 roundabouts are REALLY crash prone. There was a 2x2 roundabout in Ann Arbor that experienced 167 crashes in the first year of operations. People can argue that it's just minor fender benders, but when you have THAT many crashes, it becomes a political nightmare. I wouldn't be surprised that if only 2x2 multi-lane roundabouts were analyzed in a study, that total crashes would double and injury crashes would be about the same.

There are over 60 roundabouts in the Green Bay area with new ones being constructed each year.
I heavily admire WisDOT's consistency with roundabout design. Every roundabout in the state seems to have exactly the same set of markings.
That's because the state design manual is quite specific on how they're supposed to be marked down to the material type, at least for roundabouts on the state system. Local roundabouts are a whole 'nother story...
There's one in Rapid... and that's the only one this side of the river.

Good for WisDOT. I figured most states would be specific (at least at the state level) about markings, but at least in Washington, every time WSDOT builds a roundabout, they seems to have different markings. Very strange. And annoying.

The facts don't belong in this thread. They're off topic.
While not specific to my area, I posted a KMZ file of over 5,100 roundabouts in America that i thought could be useful to this discussion (a file I personally compiled over many, many hours). I'm trying to contribute and keep this thread on point. If someone wants to give me flack for a passing comment i made about the safety of multi-lane roundabouts, bash away.
C-DOT loves roundabouts at or near most I-70 interchanges west of Vail. In the Grand Junction/Fruita area alone over the past 10 years, 4 of the 5 interchanges with I-70 have been updated to either roundabouts (3) or a DDI. The other exits are either too low-volume or there is no room to expand.
NY 590/Sea Breeze Dr. in Irondequoit, NY has four roundabouts in a row. They were built a few years ago. NY 590 was truncated at Titus Ave. (the first roundabout) when this was done.

Here are 9 roundabouts along a 1.6 mile route outside Kansas City. It's redonkulous to have this many roundabouts back to back like this. Eliminate some of the roundabouts and make them RIRO designs. I seriously would get car sick driving through these many roundabouts in a row.

I grew up 30 miles north of Malta, NY and will be moving back to the area in a month. My hometown has 3 roundabouts with at least 3 more in initial planning stages, plus one just inside the town school complex and a traffic circle in a neighboring town (Hudson Falls). One roundabout replaced a 5-leg intersection, another was put in at a dangerous acute angle intersection, and the third was put in when NYSDEC and Warren County redid the Lake George parking lots.
I count at least 18 (I lost count) in the Malta/Round Lake area. 2 of them are brand new. Almost all were once signals. I don't feel like doing a full count of the region, but there are likely well over 30 currently in place.
Buffalo has a lot of circles within the city limits. There are a handful of roundabouts in the region. Almost all are in Amherst, northern Cheektowaga, and Hamburg, with one in the Falls, one in East Aurora, and 2 on Grand Island. Except for a couple planned ones on the UB campus, there's nothing planned that I know of.
18 seems right (that's what I just counted), though one of them is technically in Stillwater and the town doesn't acknowledge the existence of the ones in global Foundries or the one on the residential streets near US 9 and NY 67.
EDIT: Missed one. It's 19, 18 if the one in Stillwater is thrown out

I didn't count the one on Landau Blvd. I did count the new one at CR 80 and Ruhle Rd that isn't really showing up on Google Maps. 5 are inside the tech park, including the one that is barely 200 feet inside Stillwater.
Here's an old style traffic circle that's such a mess that it has three traffic signals controlling it.

It has the potential to be a very good roundabout, but I doubt Rochester has much money lying around for something like that.

Your arguments are all invalidated due to your use of the word 'redonkulous.' Please move to the time-out area immediately and await further instructions.

Nobody tell tradephoric about Milton Keynes. :)
They just added a roundabout on Dugan Road just south of US 30 in Sugar Grove, Illinois. Reason was due to the proximity of the train tracks (right at the US-30 stoplight), a side street for a subdivision on the other side of the tracks, and a driveway for some local industry along the BNSF tracks. US-30 is being redone anyways in that area between that light and the end of the IL-56 spur, probably for two lanes in each direction.

I remember when the Albany area started getting roundabouts. Everyone hated them. Then they realized that, when used properly, they actually save time. If used properly, most people don't even need to stop.

Post a route in Milton Keynes where a driver travels through 9 roundabouts along a 1.6 mile route. Then i can decide how redonkulous Milton Keynes is. Drivers shouldn't be forced to slalom through 9 roundabouts in 1.6 miles just because some engineer has a roundabout fetish.
I'm in favor of roundabouts in general, but against that Kansas City design.

Okay, I sense a theme here.
It's redonkulous to
infer that every road in the United States has the ROW of those Detroit boulevards. You know full well that you need the ROW of a typical freeway to get those things going. The reason the roundabout has been so popular is because, while you need extra ROW at the intersections, you can massively increase the capacity of a road without widening it, which is sometimes the only option.

I heavily admire WisDOT's consistency with roundabout design. Every roundabout in the state seems to have exactly the same set of markings.
Even though they may be consistent, Wisconsin roundabouts have seen a 12% increase in total crashes and a 38% reduction in injury crashes. This is a lot worse than the national numbers that show a 40% reduction in total crashes and an 80% reduction in injury crashes. Andrea Bill touches on these statistics in her TRB presentation:

Our unincorporated community got the first roundabout in this county at an active intersection --- as opposed to a partially built-out development --- about a year ago. It's an intersection (formerly a two-way stop), by the way, that I hated to navigate in the direction requiring me to turn left. I often told my wife, "This is a good location for a roundabout!" She'll roll her eyes and confirm this.
It was strongly opposed in the local paper, and since its opening there has been almost no griping. I like going through it. Most local residents seem to have figured it out.
Properly sited and designed, roundabouts can be a good traffic control option. There, I said it. I know of two or three other locations where they would be preferable to the current two-way stop.
I'm researching roundabouts for my master's and this is the sentiment I've found in my research, too. That when properly designed, roundabouts are extremely effective. They promote "traffic calming" better than stop signs, are less expensive to maintain (long term) than signal lights, can help avoid non-standard intersections (i.e. having one road be diagonal, or have five roads merge), and general create fewer traffic accidents every year than a non-roundabout intersection. I do find they are very generational, older people seem to like them less than younger people, since it's not what they're used to.
Anyway, getting back on-topic, I just saw a roundabout installed at the Hasley Canyon Road off-ramp from northbound I-5.

I have the dual Brooklawn Circles that circulate US 130 thru this area. The main one (to the right in the link below) has 3 main streets entering and exiting (US 130 & NJ 47), one side street that fights its way into the circle (Hannevig Ave), 1 street that doesn't actually go into the circle but can seriously affect traffic within the circle (Creek Rd, CR 753), and within or mere feet of the circle, no fewer than 9 curb cuts for access to a gas station, a diner, a former water ice stand, and a used car dealer.

Honestly, its the perfect traffic circle that describes everything that's wrong about New Jersey traffic circles.
NJDOT officially calls these the Brooklawn Circles; there's no separate name for either of them. On Google Maps, someone decided to name the smaller of the two 'Forbidden Circle' for some reason; nothing on NJDOT's website references that name whatsoever.
Sometime next year, NJDOT is supposed to redesign Creek Road's access into and out of the circle to prevent some of the issues that it causes, and will upgrade a nearby side street to bring Creek Rd traffic out to US 130 a short distance to the north.

NJDOT officially calls these the Brooklawn Circles; there's no separate name for either of them. On Google Maps, someone decided to name the smaller of the two 'Forbidden Circle' for some reason; nothing on NJDOT's website references that name whatsoever.
Sometime next year, NJDOT is supposed to redesign Creek Road's access into and out of the circle to prevent some of the issues that it causes, and will upgrade a nearby side street to bring Creek Rd traffic out to US 130 a short distance to the north.
Still better than Penns Neck Circle (https://www.google.com/maps/@40.3312753,-74.6378276,238m/data=!3m1!1e3) near Princeton
Ick. Penns Neck looks like a pain in the neck. Those are a bit more common in Europe than here, but signal-controlled roundabouts are ick... Looks like it could use a flyover for mainline traffic on US1
Oh, NJDOT has wanted to for years.
Just to give you an idea of where this is...it's in the same area where 95 was planned to go. So God-forbid someone sneezes, people get upset. Tell nearby residents you want to do a road construction project, and they go ballistic.
If you're on US 1 itself, it's not terribly bad, all things considering. But making any sort of turn is a pain. It's not the only one in the state like that either. Here's one on Rt. 38: https://goo.gl/maps/GMbQdJfUX5S2 . And this one on 73 at 70 did the same thing: https://goo.gl/maps/y168fabjjVR2 . The link is in GSV from 2008 because in 2009 it started to be reconstructed as an interchange.

No, it got off track when you kept bringing up accident rates on a thread that is titled "Traffic circles (roundabouts) in your area".
I simply responded to some off-topic remarks made by SignGeek101 and Jakeroot. I didn't initiate anything that was off-topic. You seem mistaken yet again. This is becoming a theme with you jeffandnicole.
To be fair to all involved, the only on-topic thing to do here would be to share about the roundabouts "in your area". It's only logical that we will end up discussing the roundabouts themselves.

I think I need those reading glasses my eye doctor recommended I wear with my contacts, or else get those bifocals he prescribed and ditch the contacts. I read that as "Penis Neck Circle." :-D

:rofl:
Wow...You are the CREATER of the off-topicness of this thread!
2 responses in, you posted a file of all the roundabouts in the United States. Unless you consider your area to be the entire country, your file had nothing to do with roundabouts in your area.
You didn't initiate anything off topic? Yeah...ok.

Yet you can't move on. (I already realize the slight hypocrisy of this post)
Until my "snarky comment" you were steering the thread towards the topic of your well-established thread which already exists elsewhere in the forums. A simple link to your existing topic was all that was needed, but instead you felt the need to rehash the same information here. That was the whole point of my "snarky post". Someone needs to take their own advice and get over them self.
Now can we
all put this in the past and get back to the original topic?
Quote from: tradephoric on December 03, 2015, 09:24:36 PMPost a route in Milton Keynes where a driver travels through 9 roundabouts along a 1.6 mile route.
Sorry, I ended up a tenth of a mile short, and with an extra roundabout. (https://www.google.com/maps/dir/52.0086797,-0.7091949/51.9981616,-0.7150182/@52.0018002,-0.727187,14.75z/am=t/data=!4m9!4m8!1m5!3m4!1m2!1d-0.7263162!2d52.00317!3s0x487655214b3fdda9:0xed6cc6b8e4238be5!1m0!3e0)
QuoteThen i can decide how redonkulous Milton Keynes is.
Don't knock it until you've been there. There's other reasons why MK is redonkulous, but the roundabouts aren't one of them. Concrete Cows, the delusion of city-hood, the accent - those are the sort of things that make MK redonkulous.
QuoteDrivers shouldn't be forced to slalom through 9 roundabouts in 1.6 miles
No one is forcing them to drive along that road, or any.
And if you slalom through a chain of roundabouts, then you are going to end up as one of the statistics you make pretty sharpish ;)
Quotejust because some engineer has a roundabout fetish.
way better than a traffic-signal fetish. Southampton is obsessed with traffic signals and smart traffic planning and is far more of a nightmare to travel around - it is the only place I've ever heard of in the UK grid-locking for an entire day with no roadworks or closures (annoying the day I moved houses within the city - sadly you can't walk 3 miles with a bed, or a car-full of rubbish for the dump, because it would have been quicker than driving). Milton Keynes' traffic nightmare is being held up for 5 minutes at rush hour.
QuoteI'm in favor of roundabouts in general
it is increasingly clear you aren't - only being in favour of them in a few specific situations, and then if they are only a certain type (single-lane)
And my post is on-topic: Milton Keynes is fairly near me - before 1994 it was in my county and is only 30-40 miles away.
And just to wind up tradephoric, here's 6 roundabouts in 0.2 miles (https://www.google.com/maps/dir/51.7457278,-0.4732962/51.7466677,-0.4734181/51.7457114,-0.4732966/@51.7461843,-0.4736098,19z/data=!4m10!4m9!1m0!1m5!3m4!1m2!1d-0.4727283!2d51.7462599!3s0x4876415fd26ca145:0x6ccbeb7689233c46!1m0!3e0) (OK, not a journey anyone would every make, other than road enthusiasts) about 10 miles from my house ;).
PS: the roundabout junctions with an at-grade mainline running through, and signals everywhere is called a hamburger. This was a term that started off on SABRE (AFAICS) but now is used by the industry people in the UK - including a horrific description of a scheme being "to hamburgerize roundabout 'x'".
...but they won't slow down the roundabout!

Kittleson & Associates, Inc. also has a database file that you could use as well: http://roundabouts.kittelson.com/Roundabouts/List/US The site includes a Google Earth KML file you can download.
The Kittleson & Associates file has 2,334 entries and includes modern roundabouts, traffic circles, and neighborhood traffic circles. My file has over 5,100 entries but focuses on just modern roundabouts. So pick for yourself which file would be useful to you (or just download both). It would be useful for K&A to separate out the KML file by the different types of circles so users can just focus on the circles that they are interested in.
Holy cow trade, that file looks like a lot of work! Out of curiosity, do you do traffic engineering for pay or just out of interest?
Speaking of routes with an abundance of roundabouts, check out portions of Carmel, IN.

I believe Carmel is, unofficially, the Milton Keynes of the USA.

According to Kittelson and Associates, roughly 70% of the roundabouts in America are single-lane. Of the multi-lane roundabouts, the 2x2 multi-lane roundabouts seem to be the ones that have questionable safety records (which makes up a small percentage of the multi-lane roundabouts). Even then, I'm not saying don't build 2x2 multi-lane roundabouts. There are plenty of reasons to build a roundabout besides the safety aspects. But if we are going to be build these, let's find a way to make them as safe as possible. Much of the "crash prone modern roundabout" thread focused on solutions to making the 2x2 roundabouts safer (effects of central island diameter, using raised truck aprons for spiral roundabouts as opposed to just paving markings, proper signage to use, etc.). I'm not an ideologue who supports every roundabout in America, but I'd say I support the majority of the roundabouts that have been constructed.
I did appreciate your post english si. You took on the challenge of finding a cluster of roundabouts in Milton Keynes and I especially liked the cluster of 6 roundabouts in 0.2 miles. I have never been to that part of the world but would love to experience the redonkulousness of MK!

This is mainly out of interest, though i do have some experience in the field. I tweaked the file to add timestamp data to make a video showing the evolution of roundabouts in
America the lower 48 since 1990.

Yes, there are roundabouts in Hawaii and Alaska, i was just feeling lazy and didn't include them in the video.
The closest to me is 55 miles away in Frederick, Maryland. US 15 and MD 464.
There's a pretty new one at the junction of CT 82 & 85 in Salem, Connecticut.

I've never gone to that - I really have no reason to, so that's why I used Frederick, cause I remember that one. But hey, it counts.
