Caline–4 Model Validation in the Nearfield of Bahadur Shah Zafar Marg, New Delhi, India

摘要

Rapid growth in the number of vehicles and vehicle activity makes this particularly true in cities in developing countries. It is generated due to incomplete combustion of the fuel in automobiles. It is observed to be as high as 70% of the total pollutants at urban environment, especially, in the near fields of urban roadways and intersections. Therefore, in present study, an attempt has been made to validate the air quality model (Caline – 4) through monitored and predicted CO concentrations. A typical urban roadway Bahadur Shah Zafar Marg containing highest traffic volume, heterogeneous traffic composition along with typical traffic flow conditions has been selected for validation of Caline – 4 model. The air quality (carbon monoxide) monitoring and prediction has been carried out as per standard procedure. The predicted values of average hourly concentration CO have been observed to be very close to monitored.......
