2、ci Abstract The objective of this study is to develop fuzzy logic based trafc junction light simulator system for design and smart trafc junction light controller purposes and also to observe its performance. Trafc junction simulator hardware is developed to overcome difculties of working in a real
3、environment and to easily test the performance of the controller. By using the trafc light simulator developed in this study, results of constant duration (conventional) trafc light controller and fuzzy logic based trafc light controller are compared where the vehicle inputs are supplied by the simu
4、lator. Statistical experimental results obtained from the implemented simulator show that the fuzzy logic trafc light controller dramatically reduced the waiting time at red lights since the controller adapts itself according to trafc density. It is obvious that the intelligent light controller is g

Introduction Most of the trafc junction signal controllers are xed-cycle type (conventional), i.e., constant green/red
6、phase for each trafc signal cycle. Although this operation style is simple, its perfor- mance is generally poor for heavy trafc. One reasonable alternative is to design an intelligent controller instead of a xed-cycle trafc light control system. Since they have many advantages, smart trafc lights cannot be ignored especially in metropolitan areas. After Zadeh dened the fuzzy sets theory in 1965, this technique has been widely used in engineering applications. Some studies
