Abstract: Based on the US EPA air pollution model, CAL3QHC version 2.0 is applied to predict Carbon Monoxide (CO) concentrations ffom road traffic at signalized intersections in Khon Kaen province, which is located in the northeastern part of Thailand. Three intersections; Sanambin school (Sm), Khon Kaen hospital (KKH) and Siarn Commercial bank (SCB) intersections; were selected for the case studies. Data collections such as the physical geometry of the sites, traffic data, meteorological data, and CO concentrations from the intersections were conducted and have been used as an input to the model. The prediction results are compared to the measurement. The results of CO concentration predictions correspond mostly to the measurements. At the SNBand KKH intersection, the predicted CO concentrations are close to those observed, except for some hours, the predicted CO concentration are varied in agreement due to the upwind location of the receptor, low wind speed and rainy periods. According to the location of the SCB intersection is in the central business district area, where it is surrounded by high buildings and is near another intersection, moreover the monitoring mobile station was located close to an underground parking lot, therefore the CO concentration observations are higher than the CO concentration prediction for working days. The ArcGIS 8.3 is used for displaying the dispersion of CO concentration each hour. It can show the dispersion of concentration and also can indicate which area is facing a problem of air pollution when analyzed with other layers such as high density of population or sensitive areas as well as an aerial photograph. This study can be used for assessing the traffic air pollution at the roadway intersections. Moreover the ArcGIS 8.3 can be used as a tool for air quality management.
