Abstract (en)

[origin: GB2448364A] Disclosed is a vehicle speed reducing system. The system has road sign with means to selectively provide a signal giving the status of the road sign and an obstructing member further along the road. The obstructing member lies across the road and has an upper surface, which is movable between a position in which the upper surface is level with the road surface and a second position in which the upper surface is vertically spaced from the road surface. The system has a control means that receives the signal and in response to the content of the signal ie detecting the speed of a vehicle, moves surface of the obstructing member so that the it moved towards either level to, or spaced apart from the road surface, when contacted by a vehicle. A sign might additionally indicate a speed limit and detect the speed of an approaching vehicle, such that the obstructing member is moved if the vehicle is travelling too fast. The obstructing member might be a speed bump or sleeping policeman with an inflatable bladder to raise and low the upper surface of the speed bump. Also the deflection of the upper surface of the obstructing member by a vehicle may be used to generate power, the power may be used to power the control unit and the movement of the upper surface. The obstructing member may contain a bladder filled with hydraulic fluid.
