Default Re: Ideal dimensions of a Speed Breaker

At many places we can see cluster of bumps, which literally breaks the car and the spine of the occupants. Is there any acceptable technical specification or standards that exist pertaining to this.

Default Re: Any recommended figures for speedbreaker height?

Speed-breakers were so far a nuisance to us. Rarely it did cause a damage to our cars. But here in Pune, an unmarked speedbreaker killed a person.

Speedbreaker removed after fatal bus accident, News - City - Pune Mirror,Pune Mirror

This person, father of my colleague, was travelling in a bus to Pune. In Hadapsar (Pune suburb), bus driver could not spot this unmarked, newly constructed, non-standard speedbreaker. People on last seat got thrown up and hit the roof of the bus.

I heard that this speed breaker was constructed near the house of the mayor.

This speedbreaker was later removed after this accident. But one live is lost that can not be reversed.

This is so tragic and so unnecessary. I don't know when the local authorities are going to be become sensitive about this.

@radek - Your post should have been in the Street experiences thread of Accidents in India thread. Pls search for the same or request Mods to move to the appropriate thread.

Mods -Sadly this thread does not in any way relate to the thread subject discussion. Request you to merge to appropriate thread

There exists another thread which discusses the subject.

Speed breakers are called Sleeping Policemen in the UK. Many years ago one of my colleagues had a project for designing a speed breaker. The design was basically a gentle up-slope and down-slopes with a large flat section, which I am not sure could be cobbled. This was safe for buses, and two wheelers as well and would serve the purpose. This gentleman retired over five years ago, and I do not know what came of it.

Sorry for bumping up an old thread. Just came across this news regarding standardization of speed breakers in Chennai.

http://www.deccanchronicle.com/14010...-breakers-come

It is high time that all municipal bodies in the country follow this example. Even the NHAI and state road development departments should look to standardize the speedbreakers. Those who have traveled on NH222 between Murbad and Malshej ghat would realize this folly. There are three places where these sharp and unmarked speedbrekers surprise the first-timers on this stretch. I myself have witnessed a rickety Tempo Trax severely damaging its underbody on one of these monsters.

It's a very important topic, as a senior BHPian mentioned, design should conform to IRC standard (IRC-99:1988), but hardly been complied with in most cities. Tragic reality !!

Attaching the IRC section, as asked by someone.

You know those white strips that are near most toll booths? about 10 feet worth of very reflective rumblers? they work better. The noise itself causes people to slow down. With "speed breakers", people simply accelerate off. The idea is to remind people to slow down in a slow speed zone; the strips work better.
