3D Zebra Crosswalk To Slow Down Speeding Cars
Heh-heh. Motivational psychology in action.

That should strike fear into the hearts of the surviving multitudes sufficient to insure general compliance. Threats and intimidation are often more effective than actual action. I was responsible for such a threat about 30 years ago. We had some new drivers on our road who failed to understand that speeding and bouncing down our rather sub-standard road would hasten its demise. Verbal roadside lectures didn't seem to have an effect. So, I painted the US standard black and yellow diagonal speed bump stripes across the road in two places. No actual speed bumps, just the paint. The speeders suddenly cooperated and slowed down, as did visitors, and even some of the long time resident drivers. I would have expected the effect to lessen as drivers discovered that there was no actual speed bump, but the effect seemed to last. Things became a bit weird about 20 years ago, when we resurfaced the road and paved over my crude pavement art. There was an immediate increase in average speed, because drivers thought that the new road surface was installed specifically to enable them to drive faster. As usual, verbal lectures failed. Instead of fake painted speed bumps, it was decided to install actual speed bumps, without the paint. There were no accidents or fatalities, but there was considerable complaining. Worse, despite the real speed bumps, the speeding continued. I would therefore conclude that it's not speed bumps or barriers that control traffic, but rather the pavement markings and/or the threat of installing real speed bumps that produced the desired effect. It remains to be seen if the same principle also applies to bicycle lane separation barriers. -- Jeff Liebermann 150 Felker St #D http://www.LearnByDestroying.com Santa Cruz CA 95060 http://802.11junk.com Skype: JeffLiebermann AE6KS 831-336-2558 |

The dominant light source would determine whether the painted shadows fall in the right place. If you look closely at the photos and renderings of the 3D pedestrian crossing in the aforementioned URL: https://www.boredpanda.com/3d-pedestrian-crossing-island/ you might notice that all the parked vehicles on both sides of the street are pointed in the same direction. Same with all of the other photos I've found: https://www.google.com/search?tbm=isch&q=3D+pedestrian+crossing Vehicles all parked in the same direction would imply that it is a one-way street, where the markings would be effective and where a driver is unlikely to approach the crosswalk from the "wrong" direction. Were the 3D crossing markers installed on a more typical two way road, the shadows would need to reverse direction to be believable and effective. At best, that would look strange and obviously fake to drivers approaching from either direction. I just wonder whether irrational shadows won't be disturbing enough to make a driver do something stupid. It's possible. However, visual oddities are not necessary to inspire a driver to do something stupid. There are plenty of other distractions which will produce the same effect. Slamming on the brakes to avoid ramming the elevated blocks would be the most likely reaction. In this regard, notice though that these 3D effects are used in town, where drivers are presumably already driving at low speed, and the difficulty is merely making them pay attention to zebra crossings. The driver will only be startled once, than he'll be expecting such tricks. Methinks you might be making too many assumptions. I live on a lightly traveled road, where one might expect drivers to reduce speed to avoid potholes, obstacles, tree roots, children, etc. It doesn't work like that. People will purchase vehicles with high ground clearance just so they can bounce over these obstacles at maximum possible speed. Andre Jute Critics take everything too seriously Yep and for good reason. If one wants see a minor change, one does not ask for a minor change backed by a reasonable argument. Instead, one asks for a major revolutionary change backed by every possible logical and emotional weapon available. Since the establishment is by its very nature rather conservative and resistant to change, the major revolutionary change will soon be scaled back to a minor change, which is exactly what the advocates originally wanted. Had they asked only for a minor change, it would have been rejected. For some unknown reason, major revolutionary changes and over the top arguments are often equated with taking the issues involved too seriously. I don't see a connection, but must admit that excessive zeal is a useful criticism. -- Jeff Liebermann 150 Felker St #D http://www.LearnByDestroying.com Santa Cruz CA 95060 http://802.11junk.com Skype: JeffLiebermann AE6KS 831-336-2558 |

I remember riding home along a paved trail in a park (Massey Creek/Taylor Creek Parks in Toronto, Canada)at dusk and suddenly encountering unpainted speed bumps on the paved trail. I was extremely glad that I was excellent at bunny hopping. I remember thinking that is was dangerous to install unpainted speed bumps on a paved trail that the City KNEW bicyclists used frequently. They sure were fun to practice bunny hopping over though. Cheers |

It remains to be seen if the same principle also applies to bicycle lane separation barriers. There's a neighborhood near here that suffered greatly from fast cut-through driving. It's streets formed an inviting diagonal between two busy roads and allowed bypassing a couple traffic lights. Drivers could save about a minute by cutting through - in other words, they could save three "traffic eternities" and get to see an extra minute of Oprah when they got home. It was a long project, but the neighborhood finally succeeded in getting "speed humps" (not "bumps") in several places. These are much more wide and gradual than "sleeping policemen" or log-style speed bumps. They jostle cars above about 20 mph, but aren't bad below 20 mph. Last I heard the residents were very happy with the results. And as a bonus, they're actually fun on a bicycle! -- - Frank Krygowski |

I take all your points on the Icelandic visual traffic calming joke, Jeff.
However, I was talking about performing arts and literary critics, because they're the kind I know. Indeed, all my life I've written criticism about any performing arts I wasn't practising myself at the time, and literary criticism too any time when I wasn't writing. I gave it up when I seemed to be writing more obits of composers, conductors and performers and writers I'd known than about live performances. Re the revos, you sound like you've been reading Saul Alinsky.

Actually, I suggested that the lack of traffic and parked automobiles might have been a result of the 3D crosswalk art. I also speculated that there was plenty of traffic before they were installed, and that all the drivers fled from the area when they saw the 3D pavement art, possibly to avoid accidentally ramming the blocks. It seems that most of the online photos and graphic simulations are devoid of automobiles. https://www.google.com/search?tbm=isch&q=3D+pedestrian+crossing It is written that anything worth doing, is also worth overdoing: https://www.funzug.com/index.php/artwork/incredible-3d-zebra-crossings-from-around-the-world.html "Velvet rope crosswalk in Montreal, Canada" https://800016.xyz/files/funzug/imgs/creativity/3d_zebra_crossings_03.jpg Maybe that will work on a dedicated bicycle lane. However, I still prefer a brick wall border. -- Jeff Liebermann 150 Felker St #D http://www.LearnByDestroying.com Santa Cruz CA 95060 http://802.11junk.com Skype: JeffLiebermann AE6KS 831-336-2558 |
