SPEED BUMPS
SPEED BUMPS
(OP)
Does anyone have any guidance in designing speed bumps or know what the allowable height of a speed bump is?

by now is there any spect. or study discussing about the design of hump or bump for different speed?

Speed humps are 12 to 22 feet long (4 to 7 m)This means both tires are on the hump at the same time. They are designed for speeds in the 15-20 mph (25 - 30 km/h) range.
Since they are more gently sloped than bumps, they put less stress on vehicles and their occupants, and snowplows are more likely to ride over them.

There are many other aspects that must be taken into consideration. For instance, many towns have had ordinances passed at the instigation of the Fire Department, prohibiting any construction of any bumps or humps in roadway. All emergency depts usually fight the issue as it results in approximately 7-8 seconds delay per "Hump".
Some of the pre fabbed humps have the initial ramp section fastened down by spikes. When the rubber or other material gets ripped by snowplows, you are left with a protruding spike. Probably best to use all asphalt, not prefabbed. (also provide for drainage to get passed the bump/hump.
Resolute speeders have found you can reduce the impact of Bumps (not humps) by increasing speed across the obstacle.
In addition, there is a growing ground swell by handicapped persons alleging pain and suffering when experiencing car spring compression during passage over bumps and humps.
There is an extensive body of such data on the internet, just search on speed bump or hump.
I have heard of making the obstacle narrow enough so that a fire truck can straddle the hump without hitting it, while still affecting cars. As most ambulances have car dimensions, I dont see this as an option.
Many places are removing them after such opposition. I would suggest using other methods of slowing traffic, and stay away from "Emergency" routes.
