In the 1990s, Leicester City Council in England sought funding for a system to integrate and enhance its existing air quality monitoring and urban traffic control infrastructures. In 1996, the EU and the Department of the Environment, Transport and the Regions (DETR) began to support projects which allowed Leicester to install the AIRVIRO air quality system. This paper gives some details of the system's dispersion modelling and real-time monitoring capabilities, and dissemination mechanisms, and discusses some possible demand management strategies developed. The air pollution data come from background and roadside air quality stations, and weather data comes from a meteorological mast. The AIRVIRO modelling facilities have been enhanced to allow the use of real-time traffic data from the city's SCOOT area traffic control system to calculate current estimates of pollutant levels. This information can then trigger traffic management measures. By 6am every morning, a 48h forecast of local air quality levels is produced. It is disseminated to the public via traffic broadcasts. When abnormally high air pollution levels are forecast, variable message signs (VMS) are also used. The paper also refers to surveys conducted during a pollution incident to assess public response, and scenario testing with road toll volunteers. For the covering abstract see ITRD E105245.
