Do people just not know how to use a roundabout?
>>1081587
Yes. /thread
lazy faggots never use blinkers when leaving one.
I stopped looking at their indicators and watch their front wheels to see whether or not they're leaving.
Some faggot overtook me and swung right in front of me to make the exit, causing me to hit him. What a piece of shit.
>>1081587
is that van in the bike lane?
>>1081649
cager.png
>>1081649
It's probably a park service vehicle out pruning bushes and other green stuff, so it's supposed to be on the bike path. Which is not the same thing as a bike lane. But, yes.
>>1081587
Only Americans.
Europeans tend to be rather used to them, though cagers, as could be expected of cagers, are stupid and do not understand the rules of road traffic, so they usually don't know when to use blinkers.
Protip: roundabout is a one way road, you don't use turn signals when entering one. You are however supposed to use them, when leaving a roundabout.

Unless it's a UK style "mini" roundabout in which case use your god-damn indicators because I am not fucking psychic.
>>1081587
Most people here in the USA aren't comfortable with them unless they're from certain parts of the northeast or other scattered places that use them.
I am from the US city with the most roundabouts, and the only place in the world I've been that is finding new ways to push the envelope of what you can use roudabouts for.

What's a mini roundabout? Roundabouts are always one way only. Everything else is just a cluster of intersections.
>>1082398
A four way crossing with a pole in the middle of it. It's a bong thing. You wouldn't understand.

>>1082419

>>1082430
Normal. I go through two of these about thirty feet apart on the way to work.
The stupid thing is they require literally no knowledge of roundabouts to navigate. They work 100% off the regular rules of the road.
Roundabouts are one of my favourite real life hack, right up there with using copyright to enforce sharing with the GPL.
>>1082438
>using copyright to enforce sharing with the GPL
That's one of my pet peeves and the most pervasive of GPL myths though. You can never enforce sharing by GPL. You can, however, find someone liable for infringing on your copyright if they do not. Meaning they are to stop what they're doing and give you lots of money - exactly as every other copyright case. You have no way to enforce sharing, though you may of course offer that as a settlement condition, should you wish to settle.
Misunderstandings like this is what fuels GPL FUD campaigns. Please don't help.
>>1082438
The biggest giants leech of GPL software, heavily improve it, do not give anything back (maybe bugfixes, but not substantial changes), and are not required to do so, as long as they offer services (SaaS), not software.
Employees making changes to GPL software do not hold copyright to the changes they make. They cannot go rogue and share GPL'd software with changes (their and their colleagues), as they have never obtained it legally, and are working on it on behalf of someone else.
Companies offering software, can sell GPL software, and are not obligated to share it with GPL community. Only the buyer. They also do not have to share the source, they only need to make it possible to obtain it, for example by request, and only for a limited time. A nice loophole, if your target audience is hardly caring about obtaining source code.
Here goes your GPL enforcing sharing.
Ironically, GPL leeches of BSD, and BSD cannot take the changes back, even though both are "free and open source".
>GPL fans said the great problem we would face is that companies would take our BSD code, modify it, and not give back.
>Nope—the great problem we face is that people would wrap the GPL around our code, and lock us out in the same way that these supposed companies would lock us out.
>Just like the Linux community, we have many companies giving us code back, all the time.
>But once the code is GPL'd, we cannot get it back.

Anyway, back on topic, opinions on turbo roundabouts?
These roundabouts require people to choose their direction before they enter the roundabout. The construction itself has two (or more) lanes, that spiral out into different paths.
This solves the problem of people crossing from the inner ring straight into the exit, like case of >>1081599
>>1082451
More turbo roundabout porn.
This one features three direction paths, out of which the ones connecting two major exists are connected by a three-lane path at their peak.
This particular one also uses traffic lights.
As a bonus, there's an elevated bike path.
Some designs use elevated separation, which makes it impossible to make a full circle or switch lanes.
There are also designs similar to mini-roundabouts, where the paths are only painted. The benefit of this design is easier manoeuvring for bigger vehicles, and easy access for maintenance vehicles like ploughs.
>>1082451
A bus entering from the right is going to have a fun time making a left. :(
>>1082452
Again how do you make a left if entering from the left.
And people think drivers can't into roundabouts.
>>1082451
>purposely use license that lets others take your code and relicense it
>throw autistic hissy-fit when people do
This is you brain on BSD. Not even once.
>>1082454
>Again how do you make a left if entering from the left.
Enter via the leftmost lane, and you can only end up turning left.
>>1082452
How does that elevated bike path avoid collisions and congestion? It seems only suited for light traffic.
>>1082453
I think the bus might not have need to use all of the exits, and hence the layout. I can't say for sure, though, as I have no idea where this roundabout is.
>>1082454
The thing might appear confusing, when looking from above. For drivers it's pretty straightforward, as they pick the lane before even entering the roundabout. You can see arrows on the entrances. All exits are reachable from all entrances.
>>1082455
You are missing the context. The GPL people tried to remove dual licensing, and make them GPL only, which is illegal.
Here's the diff.
>The files are available only under GPLv2 since now.
https://lkml.org/lkml/2007/8/28/157
You might want to read the previous link, too, if you want to have more context on it.
>>1082461
It's a bike path, its purpose is only for bicycle traffic, which is completely separated from road traffic.
>>1082464
>It's a bike path, its purpose is only for bicycle traffic, which is completely separated from road traffic.
But as soon as you have a dozen bikes or so on there everything is going to crash. They need a traffic light or roundabout for bicycles.
>>1082420
It solves the 4-way stop problem; you still give way to the left, like a normal roundabout. But it's tiny so...
>>1082424
...no you don't bother to go around it.
The downside is I have no fucking idea what direction you're planning to go as you approach the roundabout unless you fucking indicate.

>>1082497
You don't. It's not the kind of roundabout you make U-turns on.
Roundabouts are an alternative for intersections. You don't make U-turns on intersections.
>>1082495
The Dutch literally learn to ride a bike near enough as soon as they can walk. It's almost as natural as walking. You can normally walk along a pavement without crashing into somebody, after all.

It's not a roundabout.

*deep breath*
So, not the same then. In Asia, because they do it with cars, people die. In Holland, because they do it with bikes, no one dies. Kind of like in [your home country] where you do it on foot, and similarly, no one dies.
False equivalence, arsehole.
>>1082543
Nah, there are bikes and people on foot in between and there are no crashes. It's unorderly, slow and shitty though. Traffic rules and signs have a reason.
You should take more deep breaths before your hatred of cars overcomes you.

Yes, and sometimes they're - *gasp* - written differently in different countries! In some more advanced countries people know how to ride fuckinh bikes without needing traffic lights to tell them not to run other people down.
>>1082528
Roundabouts with grade separation require much more space (and money) to build. They work well on highway interchanges, but hardly anywhere else.
Might as well not mix cars going in different directions, and do something like pic related.
>>1082488
I can see this work on a wide crossing but that elevated path seems like 2-3m across.
>>1081843
>Protip: roundabout is a one way road, you don't use turn signals when entering one
Yes you do, you fuckwit.
>>1082424
You're allowed to go over it if necessary. It looks like most traffic would find it necessary to go over that particular example.
>>1082660
Culture clash. You are right indeed, in some countries (UK?) it might be allowed, or even required to use signals, signalling which exit you pick, when entering the roundabout. I see why that would work great with mini-roundabouts.
However, the problem are people who indicate which way they turn to enter the roundabout, and then do not exit using the first exit. Like if they fucking could drive in the other direction on a normal one-way roundabout.
Found a nice resource on roundabouts https://www.nidirect.gov.uk/articles/appendix-roundabouts

Used to go through here daily.
And then there is this:
>>1082454
I think you just go into the leftmost lane, and once you reach the opposite end of the roundabout, the people on the three-lane road will have a red light when you have a green light, and you can easily make a left turn onto the three-lane road to go back the way you came. I think a car in the picture is in the process of doing so...
>>1081587
it's not that, they don't know. they're just annoyed by your "traffic calming"
>>1081843
>Don't use indicators when entering
??? You do on Aussie roundabouts
>>1085339
To clear it up, you indicate to turn. If you're just going through then you go through without indicating.
>>1081587
To be fair I actually check all my driving textbooks (2004, US) and they are not covered, nor are they covered in the original federal rules of the road at the town libray.
There are no procedures or guidelines anywhere!
And they just installed one and then another two near me. But nobody informed us how they work. At the town hall meeting they say are safer, but accidents have jump 6 times what they were before they installed these things. Some of the more extreme folks are starting to act like it some government conspiracy or something. I fear it will ruin our small town. There is talk of removing the mayor unless he can fix this.
>>1085350
You don't indicate to go out if you're just going through in Straya. In Victoria, at least.

Most of those bicycles are €80 bikes with a fixed gear ratio.
>>1085580
Drivers on the roundabout have right of way, blinker on before exiting, but only after it's clear you're not taking the exit you're passing
You can turn on blinker to the left and right beforehand, so other drivers can anticipate your movement, do switch blinker around to the right at the 3rd exit
>>1085625
Thank you, I tell the others. I hope this will fix this mess. But really I blame the person who just intalled it one day without telling us.
Also what does that last part mean?
> do switch blinker around to the right at the 3rd exit
>>1085658
When entering to turn left you indicate left. As youve come 180 degrees and are approaching your exit you are now turning right to exit, and should indicate a right.
>>1085625
>>1085659
Ugh… This advice is confusing and the use of blinkers sounds dangerous.
Are you basing it on some US road laws, or just "common" knowledge?
t. Euro
As already seen in the thread, different countries use different conventions.
What's common on all roundabouts in all countries, the vehicles already on the roundabout have the right of way, and vehicles wanting to enter the roundabout should let them pass.
>>1085659
Are you sure? I live in the US, so turning left without a protected light often gets you hit as everyone turns right most of the time.
>>1085661
>the use of blinkers sounds dangerous
How easily confused can you get? You're required by law to indicate when using a roundabout, at least in my corner of the EU. I would expect that to be harmonised within the whole.
You indicate which way you intend to exit when entering, you indicate which exit you intend to take when in the roundabout. The result is:
Turning right: indicate right when entering and continue indicating until you've taken the closest exit. Stay in the rightmost lane.
Going straight ahead: don't indicate when entering, but indicate right and move to the exit lane after passing the first exit.
Turning left: Indicate left until you're approaching the exit you intend to take, then start indicating right, move to the exit lane and exit.
You indicate to make your intentions clear TO OTHER PEOPLE ALSO WITHIN THE ROUNDABOUT. They are not mind readers. They navigate close to you, and sometimes have to pass or evade you. Everyone outside the roundabout should chill the fuck out. It's not for their sake you indicate.
How this could possibly confuse anyone beggars belief.
>>1085672
>Are you sure? I live in the US, so turning left without a protected light often gets you hit as everyone turns right most of the time.
I can't even decipher what this is supposed to mean. I understand the individual words, but they don't connect. What the fuck is a protected light and what does one have to do with roundabouts?
>>1085659
Why is it important for other drivers to see where you will exit before you even entered?
>>1085677
>protected light
Without these left turns can be very dangours depending on the traffic.
>>1085677
>not mind readers
No wonder why I have to have shields up while flying through your air space. Your air craft seem to always hit me no matter what I do, those smaller explody ones are the worst. How does you high speed transportation work if you know not the path of others from their thoughts?
>>1085677
Works only for small roundabouts with 4 exit, a standard crossing.
You start indicating the will to exit, after passing the previous exit, so you don't confuse the people willing to enter the roundabout into crashing into you.
When entering the roundabout you don't indicate anything. There's only one way you can go around the roundabout (counter-)clockwise (depends on driving side).
On the roundabout, if it's a roundabout with multiple lanes, you use signals to indicate switching lanes, so no one crashes into you.
Once you approach the exit, you should switch to the outermost line.
>>1085684
On entry, for your four way one lane driving on the left roundabout, indicate left to take your first exit right to take the third or "fourth" and change to indicate left before your intended exit.
If in doubt don't indicate on entry, stick to the outside and then indicate your goal when you find it.
I assume our driving on the other side of the road friends have similar protocols.

>>1085679
>a traffic light
Are you so horribly american that you dont know what a roundabout is? I rarely say this, but please kill yourself, you cockgargling turbo retard.
>>1085678
Because if theyre behind you they want to know how as far in advance as possible what you plan to do. Also what lane to be in as not to impede or be impeded, and what distance to keep. If theyre getting out before you they can usually stay closer, improving traffic flow.
Also, communication costs nothing and never hurts.
>>1082487
>It solves the 4-way stop problem
You solve a 4-way stop problem by putting down a fucking stop sign.
>>1082459
>>1082464
Roundabouts for a 4-way intersection are nauseating. There is absolutely no reason why a simple junction cannot be controlled by just a traffic signal. If you have more than two brain cells to rub together you can figure this shit out without having to weave in and out of traffic like a third-worlder. Here, I even drew a fucking layout of how you can replace this travesty with an idiot-proof 4-way intersection.
I'm a burger and I have no idea how to use one.
>>1085734
You don't need to stop for a roundabout other than in very high volume
>>1082525
>You don't make U-turns on intersections.
You do unless sign-posted not permitted.
>>1085705
I never said to put a traffic light in a roundabout.
I said that left turns are often dangerous without a protected traffic light given the traffic. And that was in a clarifying question for reference purposes. Further more the post you replied to was answering another persons question, given someone didn't understand what the phrase "protected light" was.
Sure I was born and raised in a small isolated town that is so "horribly American" that one of the solutions at the town hall meeting was to take a backhoe to the newly installed roundabout given how many problems it made.
But these are communications and understanding issues. The state just installed these one day and doesn't tell anyone what they are or how to use them. Then people who use them all the tine wonder why the town is so angry.
You changed a part of how someone lives without even informing them, that tends to make people a bit angry regardless of the situation or person.
Difference is some people like me ask questions to learn about what is going on rather then start yelling, though to be honest I am annoyed by how this whole thing has been handled. And I am also annoyed that asking for help has gotten so many similar replies. I ask the questions not to be talked down to for not knowing, but to learn how these thing which I have never seen before work so me and the people I care about stop getting hurt. One of these accident involved my friends girlfriend, she will make a full recovery on her own, but she got bruised up badly in the accident. And their are others in the town, and their will be more accidents and injuries till we learn how to use this these roundabouts. Assuming everyone knows how to use them is what is getting people hurt in the first place, because nobody here doesknow how to use them. Thus me asking the questions.

Nobodies died, I never said that. In fact nobodies even had to stay over night in the hospital. But we got about 6 people with varying levels of bruising and I guess more then 30 fend benders.
I love how you turn "will make a full recovery" from being "bruised up badly in the accident", into "many deaths".
Just like how talking about a traffic light in the same post as a roundabout must mean I want to install a traffic light in a roundabout, despite the core idea of a roundabout is to better self regulate traffic in a safe manner.
As for being "trafficaly challenged" sure, you encounter a new traffic condition that you have no prior knowledge of and let see how "challenged" you look to the locals who deal with it every day.
Like this pic I just dug up online to prove a point. I am sure people who have this sign near them know what it means, but if you have never seen it before and you can't find it in the drivers textbooks, then what?

It is actually kind of fun guessing, but really it just highlights the danger of drivers not knowing the rules of the road which leads to assumptions that could cost lives. That why new signs or traffic patterns must be explained before drivers encounter them on the road. Ideally through their driving test or proper public notice. Bescuse ...

LOL@ (you) burgers & bongs
In the rest of the advanced world we don't have any need to draw silly circles or put down stop signs everywhere because we simply slow down and give way to the car on our right on any unmoderated intersections.
IMHO roundabouts are horrible design and confusing. In the USA we don't have very good infrastructure and are not world leaders in urban planning, but at least the nation has the sense to avoid roundabouts like the plague. For some reason the Britfag nation is in love with them though, but I would never visit a shitty nation that rains 10 months out of the year, so it doesn't effect me. I encountered my first roundabout in Greece by Nafplio(gorgeous town, definitely worth visiting) on my Brompton and it is a nightmare to deal with that shit as a cyclist.

I'm shocked.
>>1082420
Because in Britain there is no "yield to right" law. So making this mini roundabout is a method to do that (imagine on a big roundabout with left hand traffic - you would be yielding to traffic coming from right).
>>1096207
>are not world leaders in urban planning
We actuality are. We are one of the few nations with the space to properly design and plan a city.
The other nations have to find solutions to population centers instead of trying to avoid creating them.
>>1096207
But anon, roundabouts are viable solutions for areas with low population and nearly non-existent road use.
(admittedly, areas with those conditions would do just as well, or better, with unmarked intersections or yield signs)
>>1096231
Actually, drawing a grid of squares on a paper is not considered planning

Shoehorned trains/trams/bikes < Statistical analysis
>>1096236
What about traffic planning. All you have is local streets and highways. There are no main roads, and you have literally square grids everywhere - this means there's an intersection where you have to stop every 100 yards. It must take an hour to get out of your neighborhood and onto the highway in the US and then find out the highway is also jammed, because you have highway entrances and exits every half a mile.
>>1096236
Also it's not the road size that counts. You can make as many lanes on a road as you want. If they don't go anywhere, they're useless. Traffic planning means creating undisrupted traffic corridors for traffic flow; using not just highways but also main streets, secondary roads and local neighborhoods which do not connect to the main roads directly at all.

>What about traffic planning
I considered that as part of etc because it was related to the proper distribution of property types.
>There are no main roads
Not for me...
>this means there's an intersection where you have to stop every 100 yards
It's more like every 500-1000, and you're assuming that you got fucked by the lights.
Proper suburban planning is part and parcel of proper city planning.
>It must take an hour to get out of your neighborhood and onto the highway in the US
it's like 3-10 minutes to get out of suburbia for most people. Then another 1-10 minutes to get to the freeway depending on what side of town you are on and which direction you want to go.
>then find out the highway is also jammed, because you have highway entrances and exits every half a mile.
Literally a non-issue with freeways that have the right number of lanes. The rightmost lane is only for vehicles incapable of going the right speed and/or entering/exiting the freeway.
tl;dr traffic IS flow rates

Yes.

Disagree partially, it's population dependent.
At the end of the day the most important thing is designing for an intended population size, not designing around the current population size. Shoehorning only does bad things.

4 way intersections are super slow even with low traffic and are not only much more likely to result in an accident but are more deadly when they do happen so they are more likely to be head on collisions. The ONLY advantage a 4 way intersection has is that it is cheaper.
>>1081587
>reddit = 4 fags
what did he meant by this ?
>>1096264
I'm saying that other countries don't actually do urban planning because all of their cities are already formed and they are shoehorning instead of actually planning.
>>1096320
>It's not a plan if it takes into account existing circumstances
Really sears my steak…
>>1097505
You can't do proper urban planning in an already extant city without abuse of the state.

>Companies offering software, can sell GPL software, and are not obligated to share it with GPL community. Only the buyer.
The other way around. Terms of license apply only when you're distributing. The end user is not obliged to do fuck-shit with GPL as long as he's not distributing it.

Not in the US, they don't.

Roundabouts are inherently unsafe design.
Seriously think about it. Most accidents happen during maneuver. High curve turn is complex maneuver by itself. But fail train does't stops there, it forces everyone into this maneuver plus it adds additional two types of maneuvers: merging in and merging out going out simultaneously to achieve state of complete mess.
>>1098402
>High curve turn is complex maneuver by itself.
If you're overwhelmed by having to steer your car and have situational awareness, you need to stop driving. Or in fact leaving your house at all.
>>1098402
>Following a curve is a greater risk than crossing in front of oncoming traffic
Your risk sensor is broken. There are 32 points of conflict in a conventional four-way intersection, compared to 8 in an equivalent roundabout.
Have any of the driverless cars tried to deal with busy roundabouts yet?
>>1098507
be nice to him, he's american. You can get from point A to point B with only one turn due to muh grids
>>1098402
Jesus fuck what retardation. Please don't breed.

In Norway you're supposed to use the left blinker if you're going further around than straight through, to make traffic more smooth. In two-lane roundabouts this is a pain in the ass.
A lot of people don't, and I fucking hate it. You have to sit there and guess where they are going, and if you have time to enter or should stay. It clogs up traffic something horrible.
>>1100962
Not as frustrating as people not blinking out tho.
>>1081587
>Do people just not know how to use a roundabout?
Roundabouts aren't compatible with U.S. traffic laws and "normal" driving situations.
When entering a roundabout, a driver is responsible for yielding while merging, and has to have his head turned far left to see what traffic is coming.
At the same time, the driver is also required to not rear-end somebody, and has to be looking straight ahead to see who's merging.
There's no clear answer, and in reality, you have to drive while looking over your shoulder, placing complete trust in someone else as they merge in front of you.
It's a fucking nightmare, fuck traffic circles.

I once nearly had an accident on one of these things here in Germany. One of those SUVs drove straight over it and ignored my priority.
>>1100967
Those same rules apply in other countries that use roundabouts.
The basic problem in the USA is that the average driver has fuck all situational awareness and shouldn't be allowed to operate a child's push along scooter, let alone a motor vehical.

What benefits do roundabouts have other than saving $20 in electricity a year?
They are only viable in areas with low throughput, in which case an unmarked intersection with yield signs does the same job better.
>>1101043
Electricity for a signal crossing is easily in the tenthousands per year
>>1101043
>They are only viable in areas with low throughput
On the cpntrary. They offer higher throughput.
>>1085920
That looks like some retard playing SimCIty.

They have these in Utah. They're a fucking abomination. They should have just used roundabout interchanges.
>>1101052
a few square inches of leds don't cost tens of thousands of dollars. Stop including graft into your estimates, you only normalize degeneracy.
its always funny to see americans make such a big deal about roundabouts and driving stick.
i mean... come on.. ...kinda makes the "americans are retards" meme live on.
oh well
>>1101061
>They offer higher throughput.
Not him but point is roundabouts are unsafe with traffic. In low traffic they become safe as there are no other cars to collide with. But with no/low traffic
>in which case an unmarked intersection with yield signs does the same job better.
>>1101248
>unsafe with traffic
But thats complete fucking bullshit. If we're going to invent alternate realities to support our emotionally based standpoints we can argue anything. Sky is green qed checkmate atheists!

If there's someone in front of you who hasn't entered the roundabout and you feel the need to pay attention to those already on the roundabout you're driving too close to the car in front.
>It's a fucking nightmare, fuck traffic circles.
Yes they're far inferior to roundabouts.
