Abstract

The UK National Air Quality Strategy (NAQS) recognises road transport as a principal source of urban atmospheric pollution, hence an objective of the 1999 Transport White Paper was to reduce air pollution through better management of urban road traffic. Whilst there are numerous policy options available for managing urban traffic, their air quality implications at the city scale are largely unknown. This paper presents preliminary results from the application of a chain of dynamic simulation models of traffic flow (SATURN, SATTAX), pollutant emission (ROADFAC) and dispersion (ADMS-Urban), integrated within a geographic information system model (TEMMS) to assess the impact of alternative transport scenarios on air quality for the city of Leeds, UK. The scenarios addressed include "business as usual" traffic growth to 2015; network development; road pricing with cordon charging; road pricing with distance charging; and the wider adoption of clean fuel vehicle technology. The impact of these developments on air quality (nitrogen dioxide, particulates and sulphur dioxide), including exceedence of air quality standards is identified. Finally, differences in the spatial distribution of air quality (as NO2) between scenarios are highlighted, in light of their significance to social equity concerns.
