stupid idea.

rumble strips work very well, and they don't cause any crash. here I see them installed before bridges, tunnels, and on shoulders to alert drivers.

i guess same will work on normal roads just before speed limit signpost. I remember somewhere they came up with rumblers with specific speed limits beyond which they become really annoying for drivers.

What an amusing concept, reminds me of scarecrows! Eventually, the "birds" will learn to ignore them.

IMHO these these type of speed breakers are the best as they serve the real purpose of reducing speed without getting you airborne.

As I mentioned earlier why don't we use rumble strips here in India instead of those atrocious speedbreakers a.k.a car breakers. They would be cheaper to build and would cause better retardation without any major damage to the car.

Vivek are the rumble strips in the first link used to deter people from changing lanes abruptly ? Haven't seen them in India as of yet. Imagine if we had these here, they would teach the call centre cabs and the pizza delivery bikes a thing or two about lane discipline.

Illusions can't fool a keen eye. My suggestion would to post a very visible 'Humps Ahead' sign, with no humps at all. Drivers will be attentive and try look out for humps.

People slow down and try to "straddle" the hole, then breath a sign of relief they completely cleared it!

This is actually a speed control device that is in use. And it is much cheaper than speed cameras.

diabloo,
The latest pics that you have uploaded are from some ad ?

I assume its an ad for Pioneer Suspension or whatever I could read on that road. All these illusions will work only for the 1st time. Say you have "humps ahead" and no humps. And our Govt one fine day decides on introduce them! Crash trash and bang!

Bangalore Police trying something similar, but for traffic management:
Quote:
You’re all set to tear through the red light but stop suddenly on spotting a traffic policeman, arms folded, staring down at you.

Only then do you realise that the lawman is not human, but a life-size cut-out.

This is the traffic police’s novel way of stopping violators on their tracks at junctions across the city.

BHPians from Chennai. Didn't the chennai traffic police have a circle on the road with a white man painted on the road everywhere there was a accidental death. This must have been a decade back. Didn't see them when i went last year though.

I guess thats meant to scare the drivers and pedestrians and was effective to some extent.

This was tried in the UK as a series of stripes with varying spacing to slow down traffic at bad junctions in the 70's. The problem is that the locals and regulars get used to it pretty fast and then ignore it.

Yes I have noticed them a while ago. But now that the city is undergoing the metro rail construction in various places and the roads have either been dug up where work is in progress or being re-laid at places the work is over , these paintings on the roads have gone.
It actually made me to be more attentive when we come across such a painting on road.
