PREDICTING TRAFFIC EMISSIONS AND MANAGING TRAFFIC

The maintenance and improvement of air quality is increasingly a stated strategic aim of governments around the world. In the United Kingdom, the government published the document 'Air Quality: Meeting the Challenge' in January 1995 which places a duty on local authorities to establish an Air Quality Management Area where air quality is assessed to be poor within their authority. This impetus will support work already being undertaken by local authorities in drawing up their Local Agenda 21. This paper describes the development of an Air Quality Monitoring and Management (AQM&M) system, led by Halcrow Fox, in association with a number of local authorities and institutions. The AQM&M system is designed to be a tool which local authorities can use: to assess possible strategies for achieving their proposed air quality and transport objectives; to predict air pollution 'hotspots' in their area based on the integration of real time information on traffic flows and air quality, and prediction models; and to assess the effectiveness of implemented traffic control measures in achieving the defined objectives. The paper outlines the concept of a single system for air quality monitoring and management, and the systems architecture developed to enable both strategic and real-time traffic and emission prediction, to enable traffic demand management on the basis of a balance of air quality and transport objectives. It is a system designed to optimise urban transport networks on environmental criteria, rather than efficiency alone. (A) For the covering abstract see IRRD 877018.
