Density Based Traffic Light Control System Using Arduino

Abstract: In recent years, road traffic has become a serious problem across the globe. Current statistics reveals that a person averagely spends around 4-6 months of his/her life time by simply waiting at traffic signal during his travel. Generally, traffic police can control traffic in several junctions of cities by implementing either hard coded automatic traffic light control system or through manual intervention. However, the conventional hard code controlled traffic light signal which operates with a fixed time slots is found to be poor efficient since it does not consider the instantaneous traffic density. Hence, the density based traffic control system available at lowest expenditure will be helpful. The motivation for this work has been originated from the observation carried out at traffic signals located at Nizwa and Muscat cities of Oman. The proposed system includes timer which runs for a specific time and IR sensor is used to count the number of vehicles passing by during that time period.
