The report considers the environmental impact of traffic management schemes with particular regard to vehicle exhaust emissions, traffic noise and traffic vibration. It describes the methods used to assess how people perceive each major component of environmental impact, the factors that need to be considered when assessing the environmental consequences of traffic management schemes, and the measurement and prediction procedures that are available to evaluate environmental impacts. It includes a detailed review of some previous case studies of traffic management schemes and gives an appraisal of the likely effects of different traffic management schemes in influencing environmental impacts. It also includes consideration of the gaps in the knowledge that exist and gives ideas that might be used to specify a programme of research designed to gain a more complete understanding of the assessment of the environmental impact of traffic management schemes.
