How to read the numbers

The page uses percentages and percentage points so planners can understand the result without converting a 0-to-1 score.

MAPE

The model’s average percentage error for the month. Lower is better.

Within 10 points

The share of predictions no more than 10 percentage points away from the matched driver report.

Within 20 points

The share of predictions no more than 20 percentage points away from the matched driver report.

Example: If a driver reports 40% availability, a prediction between 30% and 50% is within 10 points. A prediction between 20% and 60% is within 20 points.

Interpretation note: Driver reports are not a random sample of all parking conditions. Drivers may be more likely to submit a report when the displayed prediction does not match what they see.

Prediction coverage and evidence

Every location has a weekly prediction pattern, but the amount of direct evidence differs by site.

11,791

Total locations

Every location has a complete weekly pattern covering 672 fifteen-minute periods.

6,469 · 54.9%

Site-differentiated

These patterns include direct observations from the individual site.

5,322 · 45.1%

Cluster-inferred

These patterns rely more heavily on operationally similar facilities.

How the prediction baseline works

Locations are grouped using characteristics such as capacity, facility type, fees, amenities, and nearby truck traffic.

Each group supplies a typical weekly availability pattern. Direct driver observations are then used to check or adjust individual locations where evidence is available.

How monthly validation works

Each driver report is matched to the model prediction for the same parking location and the same fifteen-minute period.

  • MAPE summarizes monthly prediction error.
  • Within 10 points shows tighter agreement.
  • Within 20 points shows broader agreement.

The bottom line

The model provides national truck parking availability patterns without requiring sensors at every facility. Monthly validation makes performance visible, while facility-level confidence information helps planners decide where the data is appropriate for screening or deeper investment analysis.
