摘要：This paper presents the preliminary analysis and trends of traffic pollutant released and assessmentresults in urban areas in Petaling Jaya, Selangor. The outcome indicates that road traffic and itsinfrastructure are the leading issues of air pollution problems in this study area. However, thereexists a lack of research that has verified this assumption, considering real-world data of localizedtraffic flow. In this study, traffic pollutants data were collected at different street categories andinvestigated prior to traffic flow data. The concentration level were then compared with severalguidelines and related previous studies where NO2 and PM2.5 show considerably high amountof concentration which exceed all of the guidelines provided. The final results reveal that mostof the concentration of the traffic-related pollutants measured except for NO2 and CO aresignificantly different at all type of streets where higher amount of concentration was found athighways and local streets rather than urban streets, attributable to the higher traffic volumeassociated with the former. The statistical analyses of both the traffic pollutants and its flowdata was then conducted, and the spatial analysis using interpolation was finally demonstrated.
