IoT İmplementation to Minimize the Vehicle Queue at the Traffic Lights Intersection

This study aims to minimize traffic jams that often occur at crossroads. Not all roads are congested with vehicles. Therefore, it is necessary to adjust the time duration for the traffic light according to the density of vehicles on a lane at the intersection. This system is based on IoT (Internet of Things) which refers to a network that connects various physical devices with different protocols. The Raspberry Pi 4 Model B functions as a controller to run the traffic light program. Infrared sensors are placed at several points to detect the queue length of vehicles and then become input to the system, then processed and converted into time duration. If the queue of vehicles is getting longer, then the duration of time for the green light will be even greater. Thus, vehicle users will be more comfortable driving because the time required at traffic lights becomes more efficient.
