Many organisations have shown great interest in the use of aggressive tactile devices for the physical control of vehicle speeds, usually in the form of road hump or speed bump. A major problem associated with the introduction of road humps on public roads is the question of legal liability for the consequences of any accidents which might occur as a result of the installation of such devices. One aspect of the design procedure needs to be clarified to assist in the question of liability. This concerns the maximum safe speed across the device, about which little information is available. It is necessary therefore that maximum safe crossing speeds should be found for selected devices, using off-road controlled test conditions, and used as part of the design input, related to the expected speed distributions at site installations. A number of authorities are likely to be co-operating in a controlled experiment to assess road hump performance, considering not only safe crossing speed, but also the characteristics of an intermediate sized design and a comparison of overseas results with those for Australian conditions. The purpose of this report, therefore, is to provide a working document which outlines in some detail an experimental design associated with that experiment. An examination will be made of the effect of selected road hump designs on vehicles and their occupants as they cross the devices. (TRRL)
