Required to design a $3-$way traffic light control system utilizing combinational logic circuits. The system should function as a standard traffic light suitable for a T$-$junction.

$-$ The traffic light system must effectively cycle through red, amber, and green lights.

$-$ You may incorporate a $555$ timer circuit to create appropriate delays between the light changes.

$-$ Utilize any combinational logic circuits at your discretion, including but not limited to adders, multiplexers, decoders, and flip$-$flops to design your system.
