Objective:

Design a traffic light control system for a simple two$-$way intersection using digital logic chips $($flipflops$,$ counters, multiplexers, and logic gates$).$

Problem Statement:

The system should control two sets of traffic lights: one for the main road and one for the side road. The traffic light sequence for each road should follow the standard traffic light rules $($Green $$ Yellow $$ Red$).$ The lights will operate in a loop with a specific time duration for each color, using digital components like counters and flip$-$flops.

Specifications:

The main road and side road will be assigned different traffic light cycles.

The main road has a longer green light duration than the side road.

The yellow light will last for a fixed, shorter period on both roads.

The red light will appear for both roads when transitioning.

There is an emergency button on each road direction. When the emergency button on main road direction is pressed, then:

o Do nothing when the traffic light on the main road is green.

o Turn immediately to green for the traffic light on the main road and the side road traffic light to red if the main road traffic light is not green.

o After this change, the traffic lights should operate back to normal cycle.

Similar response is applicable to the emergency button on the side road direction. I just want the logic circuits drawn
