Design andAnalysis ofaTwoStage Traffic Light System Using Fuzzy Logic

Conclusion and Future Works
The two stage traffic lightsystem using fuzzy logic performed better 
than the fixed time system or even vehicle actuated system due to its 
flexibility. The flexibility involves the number of vehicles sensed at the 
incoming junction and in first stage, determines the maximum urgency
