I have recently finalised tests to minimise road hump jolting. Using a Mondeo and an ageing Metro, I found conclusively, for a given road speed, road hump jolting is minimal if the car is marginally accelerating over the hump; is average if speed is constant; and is worst if still braking while passing over the hump.
As a student, physical mathematics was used to prove the benefits of accelerating round a corner. Does anyone know if the same laws of physics apply to vertical changes of velocity, or do hump jolts depend on car design?
Most over-cautious drivers appear to continue braking as they pass over each hump.
