New Haven Peanut Roundabout

- Опубликовано: 11 сен 2024
- A new and unique roundabout was just opened at the intersection of Chapel Street and Yale Avenue in New Haven, CT (right next to the Yale Bowl). The old intersection was a 45-degree skewed intersection with free flow traffic on Chapel and stop signs on Yale. Because of the angle, sightlines were terrible and crosswalks were very long. Over a three year period, 50 crashes were recorded, many of which were severe.
A roundabout was the desired solution here, but because of the odd geometry of the intersecting roads, a typical circular roundabout was not able to be designed properly. The peanut shape ensures that all approaches have optimal geometry and intersect the circulating road at the correct angle. Pinching the center of the circulating road to create the peanut shape, as opposed to an oval, saves on space needed and forces drivers to constantly turn their steering wheel, keeping speeds low (15-20 mph).

I have shared your video multiple times on a Facebook post about this intersection and it’s been very useful to help explain it to others.
Never been there but familiar with roundabout controversies!
Well, the thing which surprises me here is the reaction: awesome, great, innovative. In the Europe we call it - the standard intersection.
The roundabounds are located at all type of intersection: begining from small-ones, located on neighbourhood intersections, to the huge-one. The roundabounds are surelly improving the safety, hope New Haven won't stop the process of building roundabounds.
Nice, but where is the bike path?
looks great! but separating cyclists from that (1:45) introduced new hazard spots. they could easily flow with that (slowed down) traffic flow, and even contribute to its smoothness as there is no space for overtaking
Not all cyclists, especially children, are comfortable riding in mixed traffic. Bikes are still allowed to use the full lane and are not obligated to use bike lanes so they can choose whichever path is best for them. We want to design to accommodate all ages and abilities and provide choices
I'm waiting for the Brazilian nut interchange.
Awesome design!
I would be awesome to see what was before. But the current design looks amazing
I just looked at it via google maps satellite via, right now google maps still shows the old configuration on satellite view.
The Yalies are just copying off of Carmel, Indiana. Carmel has dozens of dogbone islands.
Nice roundabout for a slanted intersection!
Looks great!
Very innovative
Super cool edit: Could you show what this looked like before?
take a look at google maps, chapel st & yale avenue in new haven, ct. they haven't updated yet with aerial or streetview so you can see what the previous condition looked like.
@@everydayengineering thanks. I saw you added the location in the description right after commenting
now show a vidoe taken during rush hour and trucks using it..... smh......
don’t tell me what to do…..smh…..
for trucks it's worse than a normal roundabout but that is the price to pay for fewer traffic deaths
@@bestchannelintheworld only if companies would make steering tandem axle’s a thing in the US…
Apparently, there have been no fatalities, but lots of serious accidents. The video shows a 40-foot bus having difficulty staying in the middle of the donut, imagine a 53-foot trailer with another 15-foot cab of a semi trying to maneuver. The speed reduction for this vs a big oval can't be that much.
Okay, that is cool. I guess there are few pedestrians because the road is too new?
Filmed this early on a sunday morning, plus it's on the edge of a residential area so not a massive number of people walking anyways. During the day and even during construction, a good amount of foot traffic
@@everydayengineering Oh okay I see
