Air Quality Modelling and Sustainable Urban Traffic Management Strategies for Kuala Lumpur
Azliyana Azhari,Kadaruddin Aiyub,Mohd Talib Latif 한국대기환경학회 2021 한국대기환경학회 학술대회논문집 Vol.2021 No.10
This study predicts concentration and dispersion pattern of primary pollutants in Kuala Lumpur city centre. The forecast was carried out under different traffic scenarios; business as usual (BAU) and 30% traffic reduction to see the impact of traffic reduction for a sustainable city management. The Danish OML-Highway model was utilized to calculate hourly time series of particulate matter concentration and distribution caused by traffic emission under different scenario. The average concentration of PM2.5 are 37.6±24.3 μg/m³ and 35.3±23.9 μg/m³ for BAU and 30% traffic reduction scenario respectively, while average concentration of PM10 are 54.5±27.8 μg/m³ and 50.8±26.4 μg/m³ for BAU and 30% traffic reduction scenario respectively. The spatial concentration distribution of annual mean for all primary pollutants in Kuala Lumpur City Centre clearly indicated that the concentration of particulate matter decreases with reduction of traffic volume in the city. The average mean concetration for CO during the BAU runs are ranging at 861-1439 μg/m³ compared to during 30% traffic reduction run at 834-1294 μg/m³. The average mean concentration for NO₂ during the BAU runs are ranging at 31.9-95.8 μg/m³ compared to during 30% traffic reduction run at 28.6-83.9 μg/m³. Average mean concentration for PM2.5 and PM10 during BAU runs are ranging at 30.4-43.7 μg/m³ and 41.4-65.9 μg/m³ respectively compared to during 30% traffic reduction run at 29.9-40.3 μg/m³ and 40.5-59.5 μg/m³ respectively. The average mean concentration for O₃ during the BAU runs are ranging at 3.81-28.6 μg/m³ compared to during 30% traffic reduction run at 5.05-30.7 μg/m³. This research demonstrates that traffic emission in urban area originates from vehicle emission and reduction of traffic volume in the city contributes to reduce the concentration of particulate matter pollution that is harmful to the environment and human health.
