 Vehicular pollution hotspots like roadways, highways, tunnels, and parking lots leads to serious health hazards. It is necessary to take preventive actions and avoid vehicular congestion, which are the hotspots of heavy emissions. According to a recent survey, the discomfort levels in parkings and tunnels are as high as 40%. By understanding the environmental conditions in vehicular pollution hotspots, we can take effective actions like installing ambient air purifiers, automating tunnel fans, installing dust suppression systems, and regulating intelligent traffic management systems. Oism Palludrone offers a holistic solution for smart roadways, highways, tunnels and parking facilities. The gaseous pollutants here are SOX, NOX, CO and particulate matters like PM 2.5 and PM 10. The data can be utilized to understand concentration of pollutants and its health impacts. SOX, NOX and CO are the major emissions from the vehicle exhaust which float in the atmosphere. With the real-time data generated from the Palludrone, quick data-driven actions are taken. The data automates mitigation systems like ambient air purifiers, ventilation systems, and tunnel fan speeds. We can address weather impact on road safety by adding visibility and weather parameters. This enables dynamic top speed limit which can be enforced using a speed control system. Oism has currently deployed such solutions at Alwar Highway in Rajasthan and Abdul Aziz Tunnel in Saudi Arabia.
