Traffic light control sequence flowchart A typical traffic light control sequence for a 4 road junction has been described below (for a road system where the vehicles keep to their left while driving i.e. Australia, UK, South Africa etc). The light changes as per the sequence listed below: A. Before switch ON, all 4 roads should get ‘flashing yellow’ so as to enable them to look around and cross the road junction. B. When switched ON, Main roads 1 & 3 should get green signals G1/G3 to go straight. This signal remains on for 30 seconds. C. The above signals should be changed over to go right GR1/GR3 for 15 seconds only if any sensor S1/S3 of vehicles waiting to turn right is detected in the right turn lane . This will take place after a brief yellow signals Y1/Y3 in between. D. In case no vehicle is waiting for right turn, the roads 1 & 3 should be closed with red signals R1/R3 and interim yellow signals Y1/Y3 for 2 seconds. E. The above…
