This research aims to monitor the traffic condition and to control the traffic light. This system can reduce not only traffic congestion but also waiting time. This system is designed to be implemented in places nearing the junctions. This research is based on the effective use of Internet of Things (IoT). This system will display the traffic conditions in the website and the traffic light can be controlled from this website. This system has been implemented by using esp8266, ultrasonic sensor and arduino. Esp8266 nodemcu which is IoT device is used to transmit the traffic information to the website which is connected with this device. Ultrasonic sensors are placed on each road to sense the presence and absence of vehicles. Traffic information is received from these sensors. Traffic light prototype is built by using an arduino UNO. This traffic light can be controlled from the website. The system will display the traffic states in the website that can guide the drivers to select the right way and avoid traffic congestions.
