Humps? Accompanied by a weight limit/access only thing for traffic?

For humps, the camel's yer man.

Does anyone know if there is a set dimension for humps ? especially the gradient angle and height. The humps seem to vary in size and angle. I'm not against humps just want to know why some scrape the bottom of cars and not others.

Thanks alan. here is excerpt from the manual about humps.
"The only dimensions now constrained by the regulations are: maximum and minimum heights of 100mm and 25mm respectively; a minimum length of 900mm; and no vertical face to exceed 6mm in height."
It mentions nothing about angles only 'vertical face' this means that there is no specified curve or angle to the hump say, 45 degrees.
Amendment: just found this Suggested maximum on/off ramp gradient 1:10
My maths aren't good what is this angle ?
What can be done about the humps that are so very obviously more than 100mm high or do not conform ?
These ones damage my little cars undercarraige. I'm not against humps but i am against damage to my car.

Your gradient figure gives an angle of about 6 degrees. Bear in mind that the ramps will be sinusoidal not linear, so their gradients will be variable.

James, the aim is to slow traffic down; not rip the bottom out of your car. So if you or anyone else see a speed hump which you think breaks the law, please report it. It can be measured and, if needed, a bit shaved-off. (The technical term may be "scabbled".)
Here's a link to an item about the BBC Inside Out programme in 2008. They investigated speed humps and showed the evidence to the Islington councillor then in charge of their humps and bumps.
Mistakes happen. Also, road surfaces can subside or have potholes - so the hump becomes too high. (I'm about to report exactly this in a road in my own ward.) But local councils are not above the law. If we break the rules we have to correct the error.
