OPTIMISATION OF TRAFFIC LIGHT CONTROL SYSTEM USING FUZZY LOGIC AND SET THEORY

Stephy J, Arabinda Roy

Abstract: Traffic congestion is a major problem in cities. While solving this problem, it is necessary to consider the type of the road and that of the traffic intersection. This paper considers both the lane based and non-lane based roads into account. Traffic density of each road is measured by using infrared sensors. This work introduces a simple and novel algorithm to control traffic lights. Controlling of traffic lights involves two major tasks. One is to decide the next green signal which is to be on; and the other is assigning the time duration for the selected green light. In this paper these tasks are done by using set theory and fuzzy logic.
