I'd rather see them groove the roads. Less destructive, more annoying

Randomly make one or two of them real and move them around every so often...

I wonder how many people slam on their brakes thinking the illusions are the real thing?

interesting concept, would definitely be more effective keeping a few random, real speed bumps in the traffic mix and moving them around in the year.

also interesting how they didn't work as well in different locales. what works well for traffic calming in some places may be less effective in others, but a neat tool nonetheless - I wonder what holographic speed limit signs will look like beamed into the roadway?

Outstanding!

I've always envied riders who can smoothly hop over obstacles and can now join them!

For those who live in areas that do not have speed bumps quite of that design, could you post a photo of an actual speed bump of that design?

neat idea, but as metioned before, this only works for people who haven't seen them before. As for me, you broght back the jolting memory of going over a real speed bump on a fixed gear bike the first time. . . O___O that HURTS when you're not used to it !!

I like the speed bumps I've encountered around Portland.They're gentle sloping, so they don't interfere with anyone going 20MPH. Effective without being annoying.

I don't know how motorists would react, but it's funny to see how most of them react to speed bumps and speed humps.

On a few streets with parks, etc., we have a few long speed humps – the kind that are quite manageable at the 30 km/h speed limit, or even at 40 km/h. Yet most motorists tend to slow down to a crawl, and quite often they brake right on them, which means their suspension springs even more than if they were travelling it at full speed. But the ironic aspect is that those same people who drive over those humps at 10-15 km/h will drive on much more severe potholes at full speed!

So maybe these humps would be effective after all.

“We call it the novelty factor,” said Martin T. Pietrucha, an associate professor of civil engineering at Pennsylvania State University, who studies human factors in highway safety. “They may get some mileage out of it until people realize, ‘Hey, I don’t get jiggled like with a real speed hump.’ ”
Once people start to realize they're not real, make real bumps that look just like the fake ones. Then they'll drive over them real fast by accident. That will be funny.

I'm no traffic engineer and haven't stayed at a Holiday Day Inn recently, but why do speed bumps run parallel to the road? I would think perpendicular would work much better.

because it's impossible to draw such a striking false perspective for a perpendicular speed bump?

ive seen 'temporary' type speed bumps, they have slots for bike traffic and look more blocky like the virtual speed bumps than the old skool perpendicular ones.
