Traffic congestion is a severe problem in many modern cities around the world Traffic congestion has been causing many critical problems and challenges in the major and most populated cities. To travel to different places within the city is becoming more difficult for the travelers in traffic. Due to this congestion problems, people lose time, miss opportunities, and get frustrated. There are chances that people lose their lives in the ambulance itself, as it is stuck in a traffic jam. The fire brigade may not reach in time, thus leading in damage to life and property. The traffic congestion directly impacts the companies. Due to traffic congestions there is a loss in productivity from workers, trade opportunities are lost, delivery gets delayed, and there by the costs goes on increasing. To solve these congestion problems, we have to build new facilities and infrastructure but at the same time make it smart. The only disadvantage of making new roads on facilities is that it makes the surroundings more congested. So for that reason we need to change the system rather than making new infrastructure twice. Thus there is a need for an intelligent traffic light system.
