London is Using Optical Illusions To Make Cars Slow Down (fastcompany.com)

An anonymous reader shares a report: London has an interesting idea to curb speeding -- magic. The British capital has painted optical illusions on its streets as part of a pilot program to get drivers to slow down, podcast 99% Invisible notes. The idea is both pretty simple and pretty clever: use a little sleight of hand to paint the streets to look like they have speed bumps on them, but don't use finite city resources to actually build speed bumps into the road. The 18-month pilot program was launched in September of last year, according to the BBC, and the city is still determining whether the black-and-white stencils are as effective as actual bumps to deter drivers from exceeding 20mph (as if traffic in London ever goes faster than 20 mph).

    I don't slow down in my pickup truck for speed bumps. I think the effectiveness of fake speed bumps depends greatly on what kind of suspension your car has and how little you give a fuck.

      My town recently reduced the speed limit to 25. They put in solar powered radar signs which show your speed in green if it's below the speed limit, red it it's above. If you slow down to the speed limit or below the red speed is replaced by a bright orange "Thank You!".

      And the thing is, the damned things actually work. You can see people all around town slowing down to get the "Thank You!" message.

      It reminds me of Febreze. Febreze is based on a molecule that traps most unpleasant odors, but when they test marketed Febreze it was a dismal failure. It turns out you can't establish a habit of buying a product by eliminating odors. So P&G added fragrence to their odor eliminating. Or the disinfectant Bactine; it doesn't have to sting but they add alcohol so you know its working. Or the urinals in the Amsterdam airport that have a target painted on them, which eliminates sloppy peers peeing on the floor.

      People are very reward driven. It doesn't take much to be effective. Just seeing something happen is enough to motivate people to do something.

      Many european cars are smaller than American gokarts, and yes you most definitely want to slow down for speedbumps :)

      Yes, "buy, destroy and throw away" seems very much to be a part of American consumer culture. It is as if you guys think it is somehow "manly", whereas in many other countries it is seen a simply stupid. When you invest a significant amount of money in something, it is clever to take good care of it, so you can benefit from your investment for a reasonable length of time.

      I suppose it's a combination of you knowing that they are there because you need to go slowly for safety reasons, and other drivers who are less familiar with the are slowing down and forcing all other traffic to move more slowly.

      Maybe it's a bit like when they remove road markings. The road is the same but seems more dangerous so people slow down... The paint on the road adds details that make the brain work a bit harder to spot potential dangers or something.

      I don't fully understand the psychology, but it appears to keep working indefinitely from the available data.

      Here in Colorado they do something similar for cows. Where a fenceline crosses a road, the traditional way to keep cows from going through is a "cattle guard": a shallow trench across the road spanned by a steel grating that's passable by cars, but difficult for hoofed animals to walk on. Turns out you can save money by faking some percentage of them with painted stripes on the pavement.

      Of course cows are modestly intelligent at best, and don't live long enough to learn the trick...

      Yeah, that's what I'd be worried about. That instead of teaching people to slow down on these roads, it teaches people to ignore things that look like obstacles in the road. I bet someone could wreak a lot of havoc in Philadelphia by dropping concrete colored triangular prisms all over the roads. Their drivers are now trained to ignore and drive over that shape, even if their car can't clear it.

    That's what I was thinking. But if the decoy decision is local, then problems at real speed bumps at other places outside your jurisdiction is arguably not your problem. Let them ruin their suspension.

    My wife often puts clocks ahead to trick the family into getting ready on time. When we get accustomed to the inflated time, she shifts it even more. Eventually somebody puts them back to normal in protest and everybody is late for a day or two. Rinse, repeat.

    Whether it's overall better than always-honest clocks in terms of being on time is hard to say. At least she has some control over which days we are likely to be on-time, being her work schedule varies a bit. (We had to drive kids to school sometimes, so if they were late, we were also.)

    That depends on the speed bump and the vehicle, and you won't know what's what until you drive over a particular speed bump in a particular vehicle.

    We have speed trapezoids on a certain road near me. If you go over them at anything more than 3 MPH you're going to fuck your shit up. They're hardly any better than jumping a curb.

  6. They've pushed drivers well beyond breaking point by Anonymous Coward · · Score: 4, Interesting

    Last time I HAD to drive into the heart of London I did what any sensible person would do and set off at 4am, Sunday morning. I got to the city proper around 6am and the roads we're still pretty much deserted (by London standards at least) however this by no means made driving easy.

    Ignoring the average speed traps taper you down from 70 - 30 with the constant threat of fines, there are mile long stretches of road with lights ever 100 yards, and box junctions with cameras every 50. The lights are phased in such a fashion that you will be required to stop at every single light regardless of the complete absence of other traffic. Run a light - automated fine, stop in a box - automated fine.

    Add to this feature like those mentioned in TFA, the ones I saw were multicolored anamorphic cubed designed to look like debris, and the fact that even Londoners don't know their way round London and you've seeming engineered to drive people to suicide. Never mind what Soho is like in peak traffic.

    It's honestly a place where you can take a leisurely drive across the city at 5am on a weekend and by the time you've reached the other side have not only accumulated enough points for several driving bans, but enough fines to bankrupt yourself too!

  7. Re: Right! Use fake people out, until it doesn't w by Anne+Thwacks · · Score: 2
    We already have massive problems with speed bumps and slowing in London. You have no way of telling how big a speed bump is till you hit is. You get huge ones and tiny ones, and most of the markings rubbed off ten years ago. In other places, there are road repairs that look like speed bumps and speed bumps that have been removed. Some are safe at 20mph, and others unsafe at 5MPH. No way to tell till you hit them! Some people know the area, other dont.

    As a result, people slow down before and accelerate after, resulting in massive pollution problems - probably killing a lot of people, where probably none were previously killed by speed, since the congestion ensures you probably can't even reach 7MPH anyway, and causing injuries because some people (mostly motorcyclits) lose control and hit pedestrians if they don't hit a parked car first.

    In short, speed bumps in London are probably a danger to society. I am not aware of any credible research that says otherwise.

    One of the videos shows that they painted a road to look like a little girl is crouching down in the middle of the street. Maybe I'm just being silly, but my mind jumped back to the release of Windows Vista, and the initial versions of UAC.

    In case you don't remember, Microsoft released Windows Vista with the great new security feature that every time your computer was about to do something that was a security risk, a window would pop up asking, "are you sure you want to do this?" Not only was this annoying, but people quickly adapted to these interruptions by thoughtlessly clicking "Ok" or "Yes" to any window that popped up on their screen. Microsoft set up a bunch of warnings, and the result was training users to ignore warnings.

    So what I'd worry about here is that people are going to get used to the idea that these paintings aren't really speed bumps, and the little girl in the middle of the street isn't a real little girl. They'll get so used to it that they'll blow straight past it. And then, on some very unfortunate day, it'll turn out the it really was a little girl playing in the street.

  9. Speedhumps by ledow · · Score: 2

    I live in London, this isn't new. In fact there's one down the road to me that's been there for 10+ years.

    In the middle of a series of REAL bumps, there's a "fake" bump with the same painted lines, even ones that "narrow" for the bump, painted "up arrow" on the road itself, etc. But it's as flat as a pancake.

    I tell you now - it must be extraordinarily cheaper. I've seen prices of speed bumps, they are NOT cheap. However, it's singularly ineffective. Basically if you've NEVER driven that road before, you slow for it. But every one else remembers it's there (it's actually odd enough to stick in your mind whether you want it to or not) and just goes over it.

    If anything, it probably causes more problems.

    Bear in mind, I'm all for traffic-calming measures, speed limit enforcement, etc. Yes, you can all hate me. But even I just look at it and go "Well, that's useless". It's not even worth the time to paint the lines, to be honest.

    But then bumps are a pain in the arse and slow nobody, they just find alternative routes (i.e. the quiet backstreets you DON'T want them going down, near schools etc.) or bounce over them. Especially the stupid "narrow enough for you to drive straight over" ones that are supposed to slow normal traffic but allow emergency vehicles through. Those are a complete waste of time too.

    Stop fucking about, and just put an average speed camera on every corner, that alerts nearby police cars if people go through it without a license plate. It solves SO MANY problems in one fell swoop - uninsured, untested cars are immediately flagged, you can't cheat it, you can't even zip down side-streets because the next average camera will know you went over 30mph by the shortest route to do so, etc. Evidence of you breaking the law (bumps do nothing for this). Not damaging to vehicles. Doesn't need tearing up the road for.

    The only thing that actually SLOWS drivers is average cameras, proven by the M25's new cameras. And if you zoom through them, without a plate, there'll often be a cop at the next junction waiting for you and a photo of your car/face waiting for the court.

    Stop faffing about with bumps, chicanes, signs, fake speed camera boxes, etc. and just nick people if they go over 30 in a way they can't just cheat by knowing where the camera is.
