The Driver Information and Traffic Management Division commissioned the Transport Research Laboratory (TRL) to carry out track trials to assess the effect which road humps (including speed cushions) might have in generating ground-borne vibrations when commercial vehicles are driven over them. The intention was to generate advice to local authorities, to help avoid the creation of possible nuisances. Measures of vibrations were made for a wide range of vehicle types crossing a selection of road humps, and the results were used to estimate the likely effects when placed on various soil types. This leaflet summarises the investigations carried out and the results. More detailed information can be found in TRL Report 235, "Traffic Calming: Vehicle Generated Ground-borne Vibrations alongside Speed Control Cushions and Road Humps", which can be purchased from TRL.
