A speed controlling unit for maintaining a traffic hump in a raised position for a limited time to discourage vehicles from exceeding a threshold speed. The speed controlling unit includes a first surface (15a,415a,515a,615a) adapted for actuation by a moving vehicle, a second surface (15b,415b,515b,615b) which constitutes the traffic hump, and mechanical control structure (16,26; 416,426; 516,526; 616,626) for temporarily supporting the second surface in its raised position. An assembly of the speed control units may be arranged side by side across a traffic lane.
