The applicability of four simple dispersion mathematical models, namely APRAC, GZE, CALINE4, and PWILG were assessed by comparing the predicted CO and NO{sub x} concentrations with the measured values in street canyons in Guangzhou. These simple models were comparatively accurate in predicting maximum ground concentration. The accuracy of CO prediction was much influenced by the assumption of vehicular composition. The uncertainty of emission sources other than vehicle emissions was an important error source in predicting NO{sub x} concentrations.
