【 摘 要 】

Constant increase in number of vehicles and consequently significant contribution of transportation to air pollution level enforce actions leading to better assessment and emission reduction in urban areas. Advanced measurement stations are being located in key city zones to regularly monitor harmful substances concentration. As an alternative, computer modelling can be used for air quality assessment. This paper presents full process of modelling together with data preparation description. Road emission was evaluated by applying Network Emission Model (NEMO) to Legionow Square junction in Wroclaw, Poland. Geometry of study area was defined using GIS software, fleet structure was determined based on data from Intelligent Transport System (ITS) and emission factors were taken from HBEFA database. Simulation provided detailed data about transportation-related emission of various compounds, among which NOx, CO, HC and PM are of the highest importance. Results were analysed both in terms of yearly summary and spatial distribution between traffic lanes. Simulation showed extensive emission of CO, PM and NOx contributing to smog occurrence in Wroclaw. Opportunities for further improvements were discussed as well as the possibilities of applying it in planning systems and integration with dispersion models to develop complete air quality monitoring system for urban areas.
