Air Pollutant Estimation Due to Vehicles and Development of Model for Intersection

Cities and town plays a vital role in promoting economic growth and prosperity in country. With growing population, vehicular air pollution is detected as an eminent problem in Rajkot city due to high growth of motorized vehicles. The increase in travel demand has resulted in rapid growth of number of motor vehicles, buses and other mode of transportation in the arterial and sub arterial road of Rajkot city. Environmental analysis of transportation system is an inclusive and demanding task. Traffic induced emissions pose a serious threat to air quality in many metropolitan cities. Vehicle emissions from mobile source rather than stationary source are major contributors to air pollution and decadence of air quality in city. The ambient air pollution attribute to road traffic depends on different factors such as quality of fuel used, engine technology, driving conditions, emission control device, and road condition. The road traffic emissions add a significant proportion of urban air pollutants. Along with increase in motorized vehicles in city amount of CO, CO2, SOX, NOX, and particular matter is also drastically increasing which cause unhealthy air to breathe in urban areas. The results of the study are discussed and contribution of each of the measures is evaluated. The results are carried out to quantify the emissions of interest for analyzation and traffic air pollution prediction model is developed according to that.
