Why are more roundabouts being put in across California's roadways?

[@Lindleyferchel]

Driving in Europe I love them. No stop and go. Saves time and gas.

[@EnjoyFirefighting]

depends a lot on the amount of traffic which goes through there, and the road itself. Driving 3 roundabouts after another costs more gas than just driving down a straight road and a constant speed

[@lsq7833]

Cool. Too bad roundabouts replace traffic lights. Guess what happens to your "constant speed" with those.

[@miles5600]

Not always, pretty much every country except for the netherlands likes to just throw in a roundabout wherever they can. The netherlands has thought this through and they only use roundabouts at specific locations, else they’ll use traffic calming measures such as narrowing the road, single lane for cars, raised intersections, raised crosswalks, raised crossings, priority squares, etc. You don’t need a roundabout at every intersection and if your country is doing that then they’re doing it very wrong.

I lived in Carmel, Indiana, and the city is in an ongoing program to install roundabouts on all of its major intersections. They currently have completed construction on over 150 of them. They slow down traffic through the intersection, making them safer than the other intersections they save time and gasoline because they don't cause a bunch of cars to be sitting idle, waiting for the light to change colors. I loved driving in Carmel with all the roundabouts. My trips across town were cut in half. My route from my house to the church I attend took me on two busy roads with about 8 traffic signals. It took me about a half hour to drive it. As Carmel put more and more of those roundabouts in, I started driving an alternative route to church. It was not as direct a route and may be longer in mileage, but it cut my travel time in half. I am a very big supporter of using roundabouts at all intersections. Even at interchanges where diverging diamonds are replacing diamond interchanges, Carmel uses bowtie roundabouts or two roundabouts, eliminating the traffic signals still required by the diverging diamond interchange. It still seems to be a better way to move the traffic through the interchange.

[@Rebel-Forces-Earth-007]

I strongly disliked the idea of roundabouts, until I got t-boned at a regular traffic-light controlled intersection. I will admit now that they do reduce traffic fatalities, and if the intersection I got t-boned at had had a roundabout, I would not have wound up in the hospital after the other driver ran the redlight.

People get in crashes for various reasons. When we had a major road's traffic light controlled intersection replaced with a modern multi-lane roundabout it had its falsity in living memory. Multi-lane roundabouts have demonstrated time and agin they are dangerous. I watch for people running intersections to avoid a T-bone crash. Now that a local town has replaced three heavily used stop sign controlled all way stop intersection with single lane roundabouts, I was following a car when from the side street a car ran the stop sign exactly how people enter a roundtable. I saw the car approaching the main road and was watching and backed off. The car in front of me did not, braking, but still T-boning the front of the entering car at about 20 mph. Both cars are likely totaled.

The first intersection she compared with the collision data is not a roundabout. It is simply a 'traffic calming' device installed in the center of an existing intersection. In the same category as speed bumps and channeling devices.

That's exactly what roundabouts are.

[@danlowe8684]

@@_starfiend No. Roundabouts are designed as such (as in the video's thumbnail). In this case, the municipality simply put a round planter area in the middle of an intersection in an effort to calm traffic. It is still a two-way stop intersection - roundabouts do not have stop signs. The problem with roundabouts is the amount of right of way necessary. The solution they used likely helped with collisions by interrupting the flow of vehicles.

I don’t mind roundabouts especially the ones in my neighborhood that have recently been installed due to high speed drivers.

Think about kids playing in a residential area and you have regular cross intersections people tend to fly right through them. Roundabouts they’re forced to slow down.

This roundabout you compared it to is often called a neighborhood traffic circle, and in this case (as seen in the video) it also has stop signs.

[@xouxoful]

Multi lanes roundabouts are tricky to navigate correctly. Their design isn’t even consistent across countries. In France you must merge to the outer lane before exiting (but weirdly, there are 2 lane exits…) while elsewhere you may exit from the inner lane directly to the left exit lane.

[@cristolaze5309]

Roundabouts are a bit more expensive to install, but less expensive to operate than an intersection with an illuminated semaphore control.

[@piggy8761]

Theyre literally “expensive” to install because of existing infrastructure. If it were new infrastructure, it would be easy.

[@timhaigh2484]

While I appreciate the macro stats, and have no large scale data with which to counter, from my experience with a small neighborhood round-about installed near to where I live, some drivers do barrel through (over the small curb of the circle) and in rare cases other drivers cut the corner and GO LEFT (Clockwise) against the flow! To be fair, and to my amazement, no driver has hit the boulders in the center of the round-about and no car collisions have occurred. On the other hand, there have been many altercations including horn honks and "flippin' the birds" that disturb the otherwise peaceful surrounds. Clearly it is the drivers causing the problems, but these smaller round-abouts seem to bring out the worst in some drivers.

[@douglasengle2704]

The small slow single lan roundabout intersection shown at the beginning of this video is a sensible solution to replace all way stop controlled intersection. It's still bike able. There are no implicit pedestrian crossing at roundabouts as there are at stop sign controlled or traffic light controlled intersections. Pedestrian crossing have to be explicitly marked. It is highway design doctrine that a roundabout is detrimental to traffic flow of the primary road over a well implemented traffic light controlled intersection. Where a roundabout might process traffic better than a traffic light is when both roads are at about the same traffic volume and there is a lot of interchange traffic. That is atypical. It being implemented it should be done with a rotary which are safer and faster. Multi-lane roundabouts are dangerous with increased speed more typical of a rotary with that traffic condition actually calling for rotary. Once a roundabout is above a designed operating speed of 15 mph it is no longer behaving like a roundabout. Such so called roundabouts are likely not included in roundabout statistics. Most new so called roundabout in the US have designed operating speeds above 15 mph and are not roundabouts and don't have the large diameter road circles of a rotary that enable proper merging behavior. All way stop controlled intersection in neighborhoods are frequently mis used to do so called traffic calming which is where there are traffic lane disruption intentionally to slow traffic down. What takes place where traffic calming appears to have worked is not that traffic has been slowed down, but that traffic has been reduced by going somewhere else. For a neighborhood discouraging through traffic that has been a design objective as far back as the 1960s. In the USA non highway designers don't look at the fine details and are likely choosing fast multi-lane roundabouts psychologically for traffic calming. They slow traffic on the primary road that would in a neighborhood cause passing through traffic to choose a different route. On arterial roads multi-lane roundabouts used instead of a traffic light controlled intersection reduce traffic through put, make drivers hyper focus which means they may not notice pedestrians or cyclists, don't allow traffic metering such as synchronized traffic lights and make drivers fight to get through them along with disorientation that takes place after more than couple roundabouts near each other. Multi-lane roundabouts are not safer than traffic light controlled intersections. A major arterial road Mt. Comfort Road with 300 N. Mt Comfort Indiana had its traffic light controlled intersection replaced with a multi-lane roundabout where it shortly experienced its first fatal crash in living memory. www.google.com/maps/@39.8272393,-85.9148965,1636m/data=!3m1!1e3?hl=en&entry=ttu. That roundabout acts as a traffic calming device causing traffic to switch over to using 700 W. If it has been an improvement for through traffic which is the objective that would not have happened. Mt. Comfort road has a full lane shoulder typically for cycling. I feel very exposed and not noticed when riding my bicycle through that roundabout! People are hyper focusing on just a few points unable to be attentive to traffic. It looks unsafe, it feels unsafe, its slower for through traffic, it deters through traffic and its caused death over the traffic light that was there before. If implementing a traffic circle for such a situation it should be a rotary that is much larger in diameter. This is a main trucking area with a medium sized truck stop with the area being a huge warehouse area served by trucks. The roundabout provides a nice convenient turn around for Semi's.

UK/Ireland is not alone Europe: on the main Land we all yield to the right. Roundabouts is not about yielding to the left, it's just about yielding. Only because you are forced to yield through a traffic sign people need to yield to the traffic on a roundabout. I know one roundabout where you don't need to yield and where traffic inside the roundabout need to yield. (it's just a city-road with 3 exits, one to a parking lot), so there's only a miniscule of people who need to actually use the roundabout as a crossing, but when you are driving in the other direction, you actually need to yield as the one in the roundabout. Even here there aren't any accidents because of it, but this is not about yielding to the left, if the others have no traffic sign that you need to yield on the roundabout (except the parking lot where you need to), then the traffic inside the roundabout need to yield. But 99% of roundabouts there's a yield-sign, so that's rarely an issue.

[@GoldenTV3]

BRO IS ONTO NOTHING🗣❗❗❗

[@fgm5225]

In a roundabout you yield to whoever is already inside, which in (continental) Europe means yielding to the left, but in Great Britain means yielding to the right.
