Air pollution is causing increasing concern with traffic emissions being identified as a major source of pollution in urban areas. As urban regions usually consist of a complex network of roads carrying vehicles of various categories it is vital to develop high resolution emissions inventories for use with air quality models and for preparing strategies for air quality management. This paper reports on the development of high spatial resolution (1{times}1 km) CO and NOx emission inventories for road traffic sources within a 25{times}25km region of Hertfordshire, UK. The methodology adopted and the data employed to develop the inventories are discussed in detail. The total emissions for the region are compared according to road type and vehicle category. The present study clearly shows the contributions from cars and light goods vehicles dominate the total emissions of CO and NOx in the region. An important result of this study has been to highlight the major contribution made by local roads to the overall traffic-related CO emissions. This is discussed in terms of cold starts and speed dependence of the emission factors. The main sources of uncertainties are also discussed and preliminary results are presented of a survey conducted to provide information on driving habits in urban areas.
