The purpose of this study is to design a smart traffic light which consists of a sensor to detect the density of cars waiting along a particular lane. Hie main objective is to design a working traffic light system interfaces with the inductive loops sensor. The experiments and simulations are done to investigate the behavior of the inductive sensor with metal presence. From the experimental and simulations results, the best performance of inductive sensor is chose .The sequences of the light of each lane are reset according to the state of the car density. The lane with longer queue has a longer time passing than a normal queue. The implementation of the inductive sensor is to count the number of vehicles in a particular lane per unit time. The sensor will act as an input counter to the traffic light circuit. The traffic light controller will evaluate the information whether to give a long time and green light priority or a normal light sequence with a normal timing delay. The final product ofthis project which is a prototype is constructed to demonstrate the traffic light controller with inductive loop sensor.
