Density Based Traffic Light Using Arduino

This circuit is assembled on 2  feet* 2 feet MDF  board. All 4 side traffic light indicators are available & each side we are using 3 IR sensor to check traffic density. When there is no blockage on sensor then green light will be 10 second. If one sensor is blocked by traffic then green light timing will be 15  second. If two sensor’s are blocked by traffic then green light timing will be 20 second’s. If all three sensor are blocked by traffic then green light timing will be 25 second’s. according to traffic density green light timing will automatically increase or decrease.

Project customization is also available.
