Indeed. The main type of accident involving cyclists in Denmark are so called 'right turn accidents', where a lorry turning right at a junction hits a cyclists because they are in their blind spot. This obviously happens exclusively in cities.

The media has made a big deal about how tragic it is for the cyclists - which it is, but much less about how tragic it is for the driver. Remember, it's not like drivers want to hit cyclists or other soft traffic participants.

That's why I propose a separate bike road, even if it is quite an expensive undertaking. But it will make all the road users feel safe. Or -- at least -- safer.

Unfortunately, the cycling organizations don't really like to admit that most right turn accidents happen because cyclists don't seem to understand that motor vehicles have blind spots, and big motor vehicles have bigger blind spots.

As someone who regularly drives, bikes, walks and uses public transport in Copenhagen, it is blatantly obvious that people just don't know how to handle right turns involving both cars and bicycles correctly. Car drivers will leave space open on their right (between the car and the curb), instead of putting the car as close to the curb as possible (which is taught in driver's ed). Bicyclists will pile into this space, and when the light turns green, it becomes almost impossible for the driver to turn right, because of the bikes already there, as well as the additional bikes coming from behind, completely ignoring the right blinker on the car.

The mitigation of this problem is two-fold. Firstly, the drivers should not leave open space on their right, when turning right. Secondly, cyclists need to grow a sense of self-preservation and not dive into that space, even if it's open. Large vehicles need to have some distance from the curb in order to complete the turn, but that should not be seen as an invitation to cyclists.

"when the light turns green, it becomes almost impossible for the driver to turn right, because of the bikes already there, as well as the additional bikes coming from behind, completely ignoring the right blinker on the car."

Isn't that how it should be ? I'm not in DK, but in LV traffic laws in such a situation they should ignore the blinker, the driver must wait and turn right only after everyone going straight e.g. those bicycles and also pedestrians crossing the road he's turning to; since the vehicle turning must yield to everyone else.

Re:A Type of Road Junction that Kills Cyclists by avip on Wednesday January 10, 2018 @06:28AM (#16114170)
That sounds like an extremely dangerous law... In bike-crowded cities you will never be able to take a safe right-turn that way.
Re:A Type of Road Junction that Kills Cyclists by KozmoNau7 on Wednesday January 10, 2018 @08:45AM (#16114834)
You simply wait for a gap in the flow of bikes, and pull all the way to the curb, so there's no gap. Then you only really have to worry about the bikes in front of you, and any pedestrians in the crossing.
Re:A Type of Road Junction that Kills Cyclists by brewdad on Wednesday January 10, 2018 @11:17AM (#16116114)
Portland gets this wrong in every possible way. First, drivers turning right must yield to bikes in the bike lane passing on the right (not unreasonable IMO). However, state law also makes it illegal to pull into the bike lane and establish a position to turn right. Add in pedestrians and it's almost impossible to make a right turn on some roads at rush hour.

For some reason, we seem to have a lot of car/bike/ped conflicts.

Re:A Type of Road Junction that Kills Cyclists by PeterisP on Wednesday January 10, 2018 @12:06PM (#16116643)
Around here it's generally solved by having separate traffic lights for cars, pedestrians and the bike lane, and having some extra time every cycle of lights where it's red for bikes and pedestrians but green for cars to enable those turns.

E.g. this shot in google maps - https://www.google.lv/maps/@56.9578862,24.1189538,3a,75y,240... ; it's green for cars, but red for the bike lane on the right side.

Re:A Type of Road Junction that Kills Cyclists by gambiting on Wednesday January 10, 2018 @04:53AM (#16113728)
No, the law clearly says that you can never overtake a vehicle on the right - and it applies to cyclist the same as to everyone else, even if the vehicle wasn't turning right it's illegal for the cyclist to overtake it on the wrong side.
Re:A Type of Road Junction that Kills Cyclists by PeterisP on Wednesday January 10, 2018 @05:12AM (#16113819)
Do I misunderstand your traffic laws (taken from https://www.retsinformation.dk/forms/r0710.aspx?id=158005) pt. 21 about overtaking, which says "... Cyklist og fører af lille knallert kan overhale køretøjer af andre arter til højre." which seems to translate that it does not apply to cyclists and they can overtake on the right?

And 26.6 "...Ved svingning til højre må den kørende ikke være til ulempe for cyklister og knallertkørere, der kører lige ud. ..." saying that vehicles turning right must yield to cyclists going straight?

Re:A Type of Road Junction that Kills Cyclists by KozmoNau7 on Wednesday January 10, 2018 @05:26AM (#16113888)
Yes, the car must yield, which is why the best approach is to wait for a gap in the flow of cyclists, and then go all the way to the curb, leaving no gap.

Of course, bicyclists will just jump the curb, ride on the sidewalk or overtake on the left, because everyone wants to be in front.

Re:A Type of Road Junction that Kills Cyclists by KozmoNau7 on Wednesday January 10, 2018 @05:25AM (#16113882)
No, bicycles and small scooters (limited to 30kph, allowed on bike lanes) are allowed to overtake on the right.

Which is precisely why right-turning drivers should leave no gap between the car and the curb, to claim their space, as it were.

Re:A Type of Road Junction that Kills Cyclists by Quanttek on Wednesday January 10, 2018 @07:14AM (#16114383)
In almost every country (at least in Europe) cars have to yield to any traffic going stright on their right side. This includes both pedestrians and cyclists. And, yes, these have the right to overtake on the right. If straight traffic would have to yield to turning traffic, that would be way too dangerous
Re:A Type of Road Junction that Kills Cyclists by kerberos84 on Wednesday January 10, 2018 @06:06AM (#16114066)
Yes motor vehicles have blind spots that is why in driving school they teach you checking over shoulder when you turn right. Remember? And yes you should wait for pedestrians and cyclists first if you want to turn right. That is the traffic law. And maybe you can park your car on the curb so that you don't need to wait for pedestrians either!
Re:A Type of Road Junction that Kills Cyclists by KozmoNau7 on Wednesday January 10, 2018 @08:47AM (#16114847)
Pulling right up to the curb is the correct way to prepare for a right turn in a car, while sharing the road with bicycles, as taught in driver's ed here in Denmark.

And yes, obviously you check your mirrors and do a good shoulder check, that goes without saying.

But you ALSO pull to the curb after checking mirrors+over your shoulder, to claim the lane while preparing for your turn. You pull in either in front of or behind the cyclists, because the dangerous situations happen when you're side by side.

If there's a bike lane, you obviously don't pull across that, this only applies for streets without bike lanes.

Re:A Type of Road Junction that Kills Cyclists by pmontra on Wednesday January 10, 2018 @04:44AM (#16113682)
This could not apply to Copenhagen and Denmark but I guess that in most other countries cyclists are also car drivers and spend more time in their car than on their bicycle. However there are many car drivers that don't have a bicycle or seldom use it, maybe because they are scared by cars. If the driver is not a cyclist it's difficult to understand what's going on. I suggest that to get a license one should also get some practice in the traffic as a cyclist, to remember what not to do with a car.

About your mitigation strategy: that would solve the problem but unfortunately the cyclist won't stop behind the car. The cyclist would turn left to overtake the stopped car. I don't like to do that because it puts me in the middle of the road or to the right of another car. It also requires some space to maneuver and a car could be arriving from behind me and close the gap.

Usually stopped cars don't hit cyclists (but watch out for doors). I look at the traffic light and refrain from overtaking the car (both on the left and on the right) if it's about to turn green.

Re:A Type of Road Junction that Kills Cyclists by KozmoNau7 on Wednesday January 10, 2018 @05:27AM (#16113898)
There is definitely an issue with crossing over to overtake on the left, which is why the best thing to do is actually to stay behind the car, but leave some distance to the curb, to claim your position in the lane.

That way, there will be no cyclists blocking the car from turning safely, and the driver will only have to yield to pedestrians in the crossing. To put it bluntly, it's because they're idiots.

It's the same in London, a city with notoriously poor cycling infrastructure and narrow streets due to long history. Ok, it's the "left turn" mirror image version due to driving on the left not right side of the road, but otherwise the same.

That is one of the things that annoy me most about new bike lanes. Why do they put them on the left side of left turn lanes!?? Look, we have had lanes for traffic like a century now. It shouldn't be hard. They just have ti do what they always did!

(Also the stupid unsafe cycling advice of staying to the left. Take the lane and take the correct lane, please.)

Re:A Type of Road Junction that Kills Cyclists by rorykoehler on Wednesday January 10, 2018 @07:30AM (#16114449)
Many cars drivers have a habit of accelerating to get around cyclists as they are both coming to the junction where the car wants to turn left using the left turn only lane and the bike wants to go straight. I get cutoff at least once a month in this way. Very scary and usually the car drivers are oblivious to how dangerous their driving is.
Re:A Type of Road Junction that Kills Cyclists by maurits on Wednesday January 10, 2018 @05:59AM (#16114042)
If the bike lane must be next to a turn lane on an intersection, the dutch have a very simple hack [1].

All bike lanes get green, and get to sort themselves out, but crucially all car lanes get red.

Re:A Type of Road Junction that Kills Cyclists by gambiting on Wednesday January 10, 2018 @04:52AM (#16113720)
I absolutely disagree. If I, as a driver, see someone in a left-only lane, it should ba absolutely safe for me to assume that they are indeed turning left - so I can safely pull out at the junction. Obviously it leads to accidents if the person then goes straight and runs into me. Being in a left-only lane is the same as indicating a turn.
Re:A Type of Road Junction that Kills Cyclists by pbhjpbhj on Wednesday January 10, 2018 @05:30AM (#16113917)
If I as a pedestrian/motorcyclist/car-driver assume such things, eg that people not using turn indicators aren't turning then I'd have an accident at least once a day.

Making a couple of second allowance to protect the lives of other road users seems reasonable to me.

That said I don't live in an area with high cycle use - in the small UK city I'm in you're more likely to be stopping to avoid a drunk or a teenage boy doing wheelies.

>and runs into me //

Cleverly worded, but if you use your mirrors properly ... what's that phrase "hell is other road-users"?

Re:A Type of Road Junction that Kills Cyclists by talldan on Wednesday January 10, 2018 @06:08AM (#16114072)
The highway code says that cyclists should stay to the left. Even on a roundabout with multiple lanes, cyclists are supposed to stay to the left and cycle across exits.

I don't ever follow that rule when cycling, it does seem dangerous, but it is the rule, regardless of whether you disagree. You should always check blind spots when turning left, and you should have been coached to do this when learning to drive.

Re:A Type of Road Junction that Kills Cyclists by u801e on Wednesday January 10, 2018 @06:43AM (#16114253)
> The highway code says that cyclists should stay to the left.

The uniform vehicle code (which is the basis of many state road rules in the US) states the following:

>> Any person operating a bicycle... shall ride as close as practicable to the right-hand curb or edge of the roadway except under any of the following situations

>> [...]

>> When reasonably necessary to avoid conditions including [...] substandard width lanes that make it unsafe to continue along the right-hand curb or edge. For purposes of this section, a "substandard width lane" is a lane that is too narrow for a bicycle and a motor vehicle to travel safely side by side within the lane.

A cyclist riding as close to the edge of a given lane as practicable will leave roughly 2 feet between the edge of the bicycle's handlebar and the edge of the lane. The cyclist is about 2 feet wide. In a lot of states in the US, there is a requirement that a least 3 feet of space is left between the cyclist and the overtaking vehicle.

2 + 2 + 3 = 7 feet. A passenger vehicle in the US is about 6 feet wide. A commercial vehicle (e.g., truck/lorry or bus) is about 8.5 feet wide. The typical lane width ranges from 10 to 12 feet. For a 10 foot wide lane, a cyclist taking up 7 feet of space only leaves 3 feet of space for a 6 to 8.5 foot wide vehicle (5 feet for 12 foot wide lanes). That means that the two vehicles cannot safely travel side-by-side within the lane.

So, according to the UVC, there isn't a requirement to keep toward the edge of the lane in most cases.

I haven't checked to see whether the UK highway code has a similar exception to the "stay to the left part of the lane" rule.

The other problem with keeping towards the edge of the lane as opposed to riding near the middle is that the cyclist is less visible to overtaking, cross, and oncoming traffic because they're hidden by other motor vehicles or not in the field of view of a lot of drivers.

Re:A Type of Road Junction that Kills Cyclists by talldan on Wednesday January 10, 2018 @08:18AM (#16114686)
I completely agree. There are similar rules over here about leaving a gap to the kerb, and that there should also be a gap left by overtaking vehicles. Both are often not observed.

Here's the (brief) rules for roundabouts: http://www.highwaycodeuk.co.uk/rules-for-cyclists-roundabout...

Most cycling proficiency courses here in the UK will tell cyclists to ride more centrally when in a narrow lane, which is good advice. A cyclist is also legally allowed to do that.

It gets a bit fuzzy though when there's a cycle lane provided.

> It gets a bit fuzzy though when there's a cycle lane provided.

A lot of times, the cycle lane is really too narrow to safely ride in. It really ought to be a minimum of 4 feet wide (allowing a 1 foot space on each side of the cyclist if they're centered in the lane. Some that I've seen aren't even as wide as the handlebars on the bike.

Where I live, a cyclist isn't required to use the cycle lane even if one is present. Do you know whether the same applies in the UK?

Re:A Type of Road Junction that Kills Cyclists by talldan on Wednesday January 10, 2018 @12:45PM (#16117075)
You don't have to use a cycle lane here, but there have been cases in recent years where police have incorrectly stopped/charged someone for not using a cycle lane.
Re:A Type of Road Junction that Kills Cyclists by Piskvorrr on Wednesday January 10, 2018 @07:02AM (#16114340)
Should be; and as a driver, rider, and cyclist, would absolutely love to transport myself through such a world. Alas, a twenty-minute drive yesterday got me: people turning right from a left lane (across the through and right lanes, no less), people driving straight through red lights, pedestrians nearly run over on their green light by drivers turning into them, not to mention no indicator lights at all, and 10% of cars driving without any lights at all at night. (Incidentally, "world has road standards and then just ignores them" is IMHO the #1 reason that self-driving cars are not in our near future)

The highway code is a bit more nuanced than you on this topic: http://www.highwaycodeuk.co.uk/road-junctions.html

it is safer for the vehicle driver to not make that assumption, it is safer for the cyclist not to be in that position as you point out; and primarily, it is safer if the road layout does not put these different vehicles in the same space.

Seeing bike riders in London a lot of those sort of accidents (90 % of fatalities in London) are caused by cyclists undertaking agresivly.

Also the way the UK's bike lanes are set up encourage cyclists to get in front of other traffic at traficlight controlled junctions - normalises undertaking.

Re:A Type of Road Junction that Kills Cyclists by brewdad on Wednesday January 10, 2018 @11:12AM (#16116026)
You need to build the intersections properly though. My city, in the NW US, built a beautiful separated multiuse path alongside a 50mph road. The trouble comes at the southern end where two 50mph roads intersect and the separated bikeway turns into a standard on-road bike lane on the other side. This also happens to be the highest traffic volume intersection in my city of 100,000.

The intersection is designed so right turning cars can make the turn at about 15-25mph when they have the green. The same green that the cyclists have. Cyclists must wait at a position that puts them slightly behind the right turning driver and the design simply doesn't allow a cyclist to inch forward enough to change that. If you were designing an intersection that will get cyclists killed, this is how you would do it.

My approach is to stop at the green light and hit the pedestrian "beg button" and wait for the walk signal on the next light cycle (a minimum 2 minute wait). This is still no guarantee that drivers will actually yield to me, but at least it gives me a chance to be seen. Even waiting, and having the walk signal and right of way, drivers get irrationally angry at having to wait a few seconds for me to cross. A few don't wait and swing wide right in front of my path. Fun Times.

Re:A Type of Road Junction that Kills Cyclists by Quanttek on Wednesday January 10, 2018 @07:16AM (#16114396)
There is a move away from seperate bike roads because these have a much higher right turn accident rate at junctions and a move towards bike lanes which are safer due to the shared space (more awareness of bikers by drivers)
