Real-time case study on monitoring the air quality, time delay, and fuel consumption by vehicles during flyover construction

The real-time case study is carried out in the flyover construction of Periyanaickenpalayam. The major issues during the construction of the flyover are high traffic congestion; traveling distance is more due to the diversion of roads. Emissions from automobiles are often responsible for a significant cause of air pollution, and the emission causes more health-related issues. The quality of air has been affected by various factors like Carbon Monoxide (CO), Carbon Dioxide (CO2), Particulate Matter (PM), sulphur dioxide (SO2), Nitrogen Dioxide (NO2), Ozone (O3), and Lead (Pb) make up the emission levels composition. To control the emission level of pollutants, continuous monitoring of the vehicles and the level of toxic gases released to the environment must be monitored utilizing Air Quality Index (AQI). The Periyanaickenpalayam flyover construction started in December 2020, with 1.850km long, 17.2m wide, and the total cost provided by the Government is 115 crore. The flyover will start near Ramakrishna Mission Vidyalaya and ends at the Vannankovil area with 48 spans. The real-time case study is carried out by taking surveys from the people who travel by the diversion route daily. The particulate matter is monitored during the morning and evening peak traffic hours by PM 2.5, PM 10, and AQI sensors. The time delay calculation is based on diversifying vehicles going and coming on the road. The fuel consumption of vehicles is also monitored due to the diversion in the streets by mileage testing bottles. The data extracted from the selected flyover construction site using a mileage testing bottle is analyzed in humps and dumps roads and compared with the free stretch road. The case study evaluation is based on AQI, time delay calculation, and fuel consumption of vehicles in humps and dumps roads.
