Density based traffic light with automatic street light / Mohamad Naqiuddin Nordin & Mohammad Helmi Mahmud

The project is designed to develop a density based traffic signal system with automatic street light. The signal timing changes automatically by sensing the traffic density at the junction. Traffic congestion is a severe problem in many major cities across the world and it has become a nightmare for the people in these cities. Conventional traffic light system which has been used before this is based on fixed time programmed to each side of the junction which cannot be varied. Junction timings are fixed. Sometimes higher traffic density at one side of the junction demands longer green time as compared to standard time. Thus, we prefer the density traffic light system. The system contains IR transmitter and IR receiver. The IR system gets activated whenever any vehicle passes the road on each junction. The IR system will count the number of vehicles and send to the microcontroller. ARDUINO MEGA 2560 is used as a microcontroller which provides the signal timing based on the traffic density. The microcontroller will save the counting in its memory. Based on the memory, the microcontroller will set the timing for each junction based on the number of vehicle sense. For the automatic street light system, we decided to use the Light Sensor Set to control the light.
