Design the traffic signal timings of the intersection which traffic characteristics are shown in the Table. Show a detailed layout of the phasing system and the intersection geometry used. Demonstrate how AI can be used to improve the signal timings.

Assume the following saturation flows:

Through lanes $1600$ veh$/$ln$/$h

Through and right lanes $1400$ veh$/$ln$/$h

Left lanes $1000$ veh$/$ln$/$h

Left and through lanes $1200$ veh$/$ln$/$h

Left, through, and right lanes $1100$ veh$/$ln$/$h
