Emissions of pollutants from vehicles are a serious problem, particularly in dense urban areas. Traffic engineers have a role to play in reducing the adverse effects of vehicles. A project for the UK Department of the Environment, Transport and the Regions has looked at the effectiveness of managing vehicle emissions using Urban Traffic Management and Control Systems. A wide ranging theoretical study has explored the effects of potential traffic management measures and the results are presented in this paper. In general strong measures are required to have an appreciable effect on emissions. A second strand of the work was to test two measures, queue relocation and a modified UTC algorithm on street in Birmingham and Leicester. The preliminary results of those trials are included in this paper. For the covering abstract see ITRD E114174.
