Abstract
The applicability of General Finite Line Source Model (GFLSM), based on the Gaussian diffusion equation, was assessed by comparing predicted CO concentrations with the measured values obtained from the experiments conducted by Central Pollution Control Board (CPCB), New Delhi, India at three traffic intersections in the Delhi city. Using the CPCB data, a Delhi Finite Line Source Model (DFLSM) has been developed by modifying the GFLSM, considering the existing traffic and meteorological conditions in the Delhi city. The predicted and observed CO concentration data reveals that the DFLSM model works more accurately for the existing traffic and meteorological conditions in the Delhi city in comparison to the GFLSM.
