Traffic volume is a significant method to study the time and movement of vehicles on the road. The study was carried out at six different sampling sites in Greater Noida. The current study effectively analyzed the peak hours of several roadways using traffic flow per hour. To perform this study, the traffic flow per hour in the research region was calculated using both manual and video camera (photographic) approaches. Additionally, PCU (Passenger Car Unit) data was utilized to examine how urban roadways were used. According to PCU data, there are a lot of two-wheelers in Greater Noida, with 206 PCUs in total. This indicates that a lot of two-wheelers use the city's roadways. The results of the PCUs show that the 2-wheelers are the major contributor to urban air pollution. As 2-wheelers use petrol as their fuel, the composition of their exhaust emissions is like that of gasoline- operated vehicle emissions.
