Abstract

Road traffic congestion has become one of the most important challenges in metropolitan areas as a result of population growth, increased demand for vehicles and a lack of transportation facilities. It has negative consequences for the environment, the country’s economy as well as human physical and mental health. Traffic congestion causes severe air pollution and noise pollution, which aggravates the entire environment. Millions of people around the world are directly affected by traffic congestion every day. Due to an exponential expansion in population and vehicle, the current traffic structure is unable to meet traffic demand. There is a need of real-time traffic light system in which signals will operate automatically based on the density of the vehicles. The need of a real-time traffic light system for reducing the detrimental effects of road traffic congestion are highlighted in this research paper.

Key words: traffic congestion, real-time traffic light system, density of the vehicles
