1. Build a PLC ladder program for controlling traffic light sequence of a 4-way intersection. 2. Green lights will be ON for 80 sec and yellow lights for 10 sec. 3. Implement a system where, if the traffic is low in one lane, other lane's green lights will be ON before 90 sec. 4. On the west side there is an extra button (x) to help crossing the street from west to east. When a pedestrian presses "x", it forces the green light to change into yellow after 20 sec. 5. Provide a reset button for the whole system. 6. Modify the system for a left turn signal from east to south only. 7. Properly mention all the inputs, outputs and sequential mechanism in a project report format. 8. Clearly explain any issues faced during designing the system. Provide any alternative solution if necessary and possible. Traffic Light Sequence Control West R2 Y2 G2- X 111 | R V G GIVI RI South G2 Y2 R2 East
