The success of a traffic management scheme will depend ultimately on the acceptance by the general public of the scheme. This in turn will depend on how the various impacts of the scheme, including impacts on the environment, are perceived. The development of methods for predicting public reaction to the environmental impacts of schemes might therefore help planners to improve their popularity, and to reduce the need to alter or remove those that are particularly unpopular on environmental grounds. Potential predictive methods include the use of dose-response relationships and the analysis of existing attitude surveys conducted at schemes. This review examines the current understanding of the dose-response relationships for three important components of environmental nuisance - air pollution, noise, and vibration - and records how subjective responses to these components have been influenced by traffic management schemes. Current predictive capabilities of both the methods considered are found to be inadequate for use with traffic management schemes. It is suggested that further work is required to determine the relationships between traffic parameters and perceived environmental nuisance. (A)
