  This report describes a study to assess ground-borne vibration levels generated by a wide range of vehicle types crossing different road humps and cushion designs. For each vehicle, drive-bys were performed at speeds between 15 and 45 km/h which represented the range of typical crossing speeds recorded on the public highway for the profile designs used in the study. Ground-borne vibration was detected at a reference distance beside each profile design and the maximum level recorded for each drive-by event. The data was used to predict likely maximum levels of ground-borne vibration alongside each hump and cushion design for a range of site conditions. From these predictions, minimum distances between profiles and buildings to avoid disturbance to the occupants have been recommended. When selecting traffic calming measures, Highway Authorities may find the results of this study useful to reduce the risk of residents being exposed to levels of vibration likely to cause disturbance. Minimum distances from each profile design are also given within which minor superficial damage to buildings could possibly occur although the risk of this is generally small.
