AI Signal Optimization
The model uses current simulated queue length to distribute green-light time where it can reduce delay most effectively.
High traffic
Longer green phase
Queues of 36 or more vehicles receive a 62-second recommendation to restore flow.
Medium traffic
Balanced green phase
Queues from 20 to 35 vehicles receive a roughly 42-second recommendation.
Low traffic
Shorter green phase
Smaller queues use a 24-second recommendation so unused time returns to busy approaches.
Current AI decisions
Each recommendation includes a transparent reason, not a black-box result.
North approach
62s green time
High inbound queue needs extended clearance time.
Based on 42 simulated vehicles.
South approach
40s green time
Balanced demand can be cleared in a standard phase.
Based on 25 simulated vehicles.
East approach
24s green time
Low vehicle volume allows a shorter green phase.
Based on 13 simulated vehicles.
West approach
44s green time
Moderate queue requires a slightly extended phase.
Based on 31 simulated vehicles.
