The traffic hump has been investigated with regard to marking, shape and construction. The traffic-hump is defined as a rise over a short length and over the whole width of the pavement. Vehicle-engineering aspects and the speed regulating effects of several hump shapes are researched. Some of the main conclusions and recommendations are (1) traffic humps influence driver behaviour (2) drivers should not be troubled at low speeds, but inconvenience will rapidly increase at speeds in excess of 25 km/h (3) sinusoidally shaped humps are satisfactory (4) markings of alternate short and long light-coloured stripes longitudinally, together with a single broad transverse line on a dark background, are recommended (5) the influence of humps in a residential street is not limited to that street alone and (6) with humps in series, their spacing should be min 40 and max 60 M.
