During summer 2002 a special directive about employees' health and security at exposure to risks due to vibrations during work, also called "Physical agents vibration directive" (Directive 2002/44/EC), was adopted by the EC. The member states had until July 6th 2005 to transfer the directive into the national legislation. Certainly the condition of parts of the road network can be such that the vibration levels that professional drivers are exposed to exceed the limits that are given in the vibration directive. VTI has therefore been commissioned to carry out a pilot study including a survey of the responsibility of the Swedish Road Administration (SRA) as well as the interpretation of the directive made by the Swedish Work Environment Authority, but also to study how different designs of the road's longitudinal profile may give rise to vibrations that are harmful or uncomfortable to humans. The present pilot study has included a literature survey concerning vibrations and their influence on humans with particular reference to roads and their design, demonstration measurements of road geometry and vibrations and analyses of these with regard to the directive as well as discussions on suitable measures for health risks or discomfort during travel on road.
