Investigating the Effect of Traffic Flow on Pollution, Noise for Urban Road Network

Abstract

Abstract Congestion has a significant impact on the environment. It’s the predominant source of pollution, as noise and air pollution. The sound produced by vehicles as well as horns creates the worst possible environment. High motorized traffic flow nowadays is the major contributor to rising externalities, vehicle emissions, and other pollutants that impact the environment and the atmosphere, which result in negative atmospheric phenomena, global warming, and climate change. Vehicle emissions cause numerous vulnerabilities, so a serious consequence may arise in the long term, both regional and global. This study investigated Noise and pollution for different roads in the different cities based on field data at peak periods of traffic flow, shows that the major pollutants that are emitted from engines are: nitrogen oxides (NOX), carbon monoxide (CO), unburned hydrocarbons (CxHy), sulfur oxides (SOX), solid particles, including aerosols, as well as carbon dioxide (CO2).
