Two models IT Line Source Model (IITLS) and H1WAY-2 model have been used to estimate the concentrations of the hydrocarbons (HC) and oxides of nitrogen (NOx) due to transportation sector. An elaborate source inventory for the extrapolation of the HC and NO. emissions by vehicular transport has been developed in IITLS model. The model's predicted concentrations have been compared with the observed values at three receptors namely, Mool Chand, Ashram and AIIMS in Delhi. A statistical error analysis of the model's results and observed values has been made for evaluating the model 's performance. In the present study, it has been observed that IITLS model performs better than HIWAY-2 model.
