11 A quantitative analysis to determine modelling uncertainties was applied, based on the maximum deviation of the measured and calculated levels within the considered period. 12 Using this approach, the average uncertainty of the model prediction for this study slightly exceeds the 50% acceptability limit defi ned by Jiang.7 13 Nevertheless, these results suggest that data obtained using TEM to simulate CO exposures may provide more sensitive information for assessing the impact of traffi c management strategies than traditional on-site measurement. 8________________
