A method of controlling the speed of vehicles comprises installing deformable speed bumps across the road such that up to a designed control speed, the speed bumps will deform due to the displacement of a fluid within the flexible hollow casing (5), allowing vehicles to pass over them with the minimum of disturbance. As the speed of vehicles increases above the designed control speed, the displacement of the fluid within the speed bump is progressively reduced so that the disturbance to vehicles increases as their speed rises. <IMAGE> |
