Intelligent Traffic Control System

Traffic is a major concern for most of the metropolitan cities of the world. Efficient traffic management can have a major impact on the country\´s economy. This paper proposes a new digital-logic based system which is more efficient than currently used traffic control systems. The intelligent traffic control system (ITSC) is based on a simple principle; the principle being that "a car can only move ahead if there is space for it" and "the signal remains green until the present cars have passed". By placing sensors at every entry and exit of a junction and monitoring the number of cars present at the junction, it is possible to make traffic very efficient, which is a good application of digital signal processing. However, absolute advantage of such a system will only be felt if every junction in a city is controlled by this system.
