Dimensions of Speed Humps

Of course there are several different types of vertical deflection, with variable effectiveness. The most effective are taller and steeper. The least effective types are most in vogue for reasons you can probably guess. Sorry I don’t have the source for this in front of me.

P.S. One speed hump costs about 2K$, roughly 1/8 the cost of a mini roundabout. By all indications they are far more effective traffic calmers than are mini roundabouts.
