Air pollution from traffic in topographically complex locations.
In the UK, many improvements and modifications to the road system are made in urban areas where the network of roads and the surrounding area are often complex. In these locations, the emission and dispersion of vehicle exhaust are complicated by the diversity of the vehicle operating conditions and of the airflow patterns. A series of air pollution surveys have taken place at successively more complex sites. A preliminary analysis of the results has been carried out to determine the features that are most important in determining local pollution levels. These will be considered in the future development of methods of predicting pollution levels that are more accurate in topographically complex locations.
