Summary:The purpose of this study was to examine the performance of USEPA nonreactive Gaussian air quality dispersion model, the Industrial Source Complex Short-Term Model (ISCST3), in simulating roadside air pollution concentrations on daily and vacation traffic flow in Taoyuan, Taiwan. Air pollution produced from diesel vehicle in the urban area, including CO, NO^sub x^, P^sub M1^0, PM^sub 2.5^, and SO^sub 2^ was simulated its dispersion. Emission factors for different diesel vehicles were estimated by using MOBILE6.2. The ISCST3 simulation was performed to predict the spatial distribution of air pollutants from mobile sources for daily and vacation traffic flow. The emission rates were different from various mobile vehicles. Finally, the concentration of five air pollutants was successfully simulated and presented as dispersion map. The highest concentration of CO, NO^sub x^, PM^sub 10^, PM^sub 2.5^, and SO^sub x^ on daily traffic flow is 0.0287 ppm, 21.9 ppb, 0.849 µg/m^sup 3^, 0.18 µg/m^sup 3^, and 0.404 ppb, respectively; on vacation traffic flow is 0.0195 ppm, 15.5 ppb, 0.555 µg/m^sup 3^, 0.117 µg/m^sup 3^, and 0.267 ppb, respectively. In addition, the concentration of five pollutants on daily traffic flow was all higher than that on vacation traffic flow. Distribution of air pollutants also indicated that the traffic flow of diesel vehicles would significantly affect the dispersion of pollutants. Therefore, strategies for air pollution control in urban area will of necessity need to focus on the vehicle sources. [PUBLICATION ABSTRACT]
