Evaluation of Urban Vehicle Emissions Using Traffic and Emission Models - An Overview

Due to the country's rapidly growing population and economy, transportation has become an essential part of Egyptian life. Air quality has decreased as a direct result of the rapid increase in urban areas' vehicle use due to human activities. In Egypt, almost 48.1% of all trips are taken by private automobiles, whereas public transportation is utilized only sometimes. Heavy congestion is the direct result of people's reliance on personal automobiles. More than 98% of the world's population in 2019 was located in regions where air quality did not meet World Health Organization (WHO) criteria. About 32% of Egypt's 2019 emissions came from the transportation sector. Different aspects that define the causes and possible alternatives to the air pollution problem at intersections are addressed in this research. Three intersections in Zagazig are the focus of this project, which looks into ways to reduce emissions from moving cars. PTV VISSIM generates a realistic peak-hour traffic simulation of the current traffic situation. Emissions are calculated using the data collected from the vehicles in the traffic simulation as input to the emission modelling software COPERT.
