Fuzzy Traffic Controller
A complete traffic signal cycle in the signalized intersection usually consists of the red, green 
and amber (or yellow) phases, which are turned on sequentially in a fixed time interval. Only the 
cars facing an activated green signal have the right of way to cross the intersection – moving 
straightforward, turning left, or turning right. The cars facing an activated red signal do not have 
the right of way and are forbidden to pass through the intersection. However, the cars are 
allowed to make right turns with the red signal as they do not interfere with those cars having the 
right of way to cross the intersection. The amber phase is activated in the transition from the

green phase to the red phase. Typically, the amber phase is fixed in duration. The durations of 
the red and green phases are determined by the prevailing traffic conditions over a large 
coordinated area. Two case study of fuzzy traffic control system are given below:
