Roads are the major contributors to the socio-economic development of a nation helping in improving connectivity. India has one of the largest road networks in the world with about 47 lakh km of road length. Transportation of over 60% of consumer goods and over 85% of passenger traffic happens on roads in India. In India, 2018-2019, the highest allocation of budget is towards road infrastructure, which helps in developing new roads and improving the condition of existing roads. India's urban

... ulation was around 377.11 million in the 2011 census. This rapid urbanization has also led to rapid motorization. Urban roads have a high volume of traffic making it necessary to install traffic signals at intersections for better control over the flow of traffic. Though urban signalized intersections helps in regulating the traffic flow in a shared space, it also acts as the zone of major congestions, accidents and increased levels of air pollution. In this study, a simulation of traffic flow at Goripalayam and Periyar signalized intersections is to be carried out along with the incorporation of air pollution levels and possible conflicts at intersections. Simulation of the intersections will help in achieving an optimized signal control plan that will help in reducing the total delay, accidents as well as the pollution levels at the intersections which in turn will give rise to a more efficient intersection for the road users.
