Abstract

Road traffic represents one of the major sources of air pollution in urban areas, and substantial effort is devoted the development of technological and transport policy measures to reduce its impacts. To determine whether ambient air quality standards are exceeded, a variety of atmospheric dispersion models are employed to predict vehicular pollution effects. The purpose of this project is mainly to develop an atmospheric dispersion application to predict the impacts of air pollution hazard. Equations and algorithms representing atmospheric processes are incorporated into various dispersion models. In this case, source model of air pollution is identified from line source emission specifically roadway emission. The basic concept of the roadway air dispersion mode! is to calculate air pollutant levels in the vicinity of an urban street canyon. The main attraction of this model lies in the simplicity of its application. Measured traffic and meteorological data were used as the input parameters in the model. Producing the calculations is complex that a computer model is necessary to arrive at reliable results. The results will show the concentration at specific area on the road and the concentration of pollutant at certain distance. These calculations are produced and simulated in Microsoft Visual Basic 6.0. The results obtained are then compared with actual value to from case study. The software proves to be reliable when the error produced is very low. IV
