Use Case Note
■ Inputs and Prior Actions
■ Actions
    • for each segment
        ♦ Grab the Current Segment State Vector:
            ♦ Current Condition,
            ♦ Last Major Action(LMA)
            ♦ Predicted Future Conditions under Nominal Actions,
            ♦ Thresholds for good to fair and fair to poor
            ♦ Traffic Vector
        ♦ Prediction process (Monte Carlo or ML)
            ♦ Now
            ♦ Next cycle
            ♦ Threshold crossings for each variable
            ♦ Earliest crossing determines remaining life
                ♦ Utilize ML Algorithms in concert with or separately to Monte Carlo Calculations on existing sampled data
        ♦ Result is a weighting on Remaining life before doing something either light or heavy
■ Outputs
    • Remaining life prior to actions

Actions
Steps
1. Actor - KDOT PMS Modeler identifies the segments to process
2. SYSTEM for each segment
    2.1. Grab the Current Segment State Vector:
        2.1.1. Current Condition,
        2.1.2. Last Major Action(LMA)
        2.1.3. Predicted Future Conditions under Nominal Actions,
        2.1.4. Thresholds for good to fair and fair to poor
        2.1.5. Traffic Vector
        2.1.6. Predicted Future Conditions
    2.2. Prediction process
        2.2.1. Now (Steady State for Baseline)
        2.2.2. Next cycle
        2.2.3. Threshold crossings for each variable
        2.2.4. Earliest crossing determines remaining life
            2.2.4.1. Utilize ML Algorithms in concert with or separately to Monte Carlo Calculations on existing sampled data
    2.3. Merge Remaining life prior to actions into current Segment State Vector
