Performance evaluation of general finite line source model for Delhi traffic conditions

摘要

The applicability of General Finite Line Source Model (GFLSM),based on the Gaussian diffusion equation, was assessed by comparingpredicted CO concentrations with the measured values obtained fromthe 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 Mod!el (DFLSM) hasbeen developed by modifying the GFLSM, considering the existingtraffic and meteorologicaI conditions in the Delhi city. Thepredicted and observed CO concentration data reveals that the DFLSMmodel works more accurately for the existing traffic andmeteorological conditions in the Delhi city in comparison to theGFLSM.
