TRAFFIC LIGHT CONTROL USING INDUCTIVE LOOP SENSOR

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.
