Abstract

Traffic performance-based air quality management M. Granberg & J. Niittymaki Helsinki University of Technology, Laboratory of Transportation, Finland. Abstract Traffic is a major strain on air quality in cities, as most of the hazardous emissions in urban areas are caused by it. Road traffic causes such emissions as CC>2, NO%, NO], HC and CO. Road traffic induces also particles, of which especially small particles are extremely hazardous to health. Accurate modelling of traffic and traffic-generated pollution is important in estimating the exposure caused to people. Being able to correctly model traffic and its emissions helps in finding different traffic control strategies that could be useful in improving the situation in extensive air quality management systems. Granberg et al [1] presented a combined application of traffic microsimulation and street canyon dispersion models, which was tested on a case study in Helsinki. The purpose of the study presented here is to continue
