Methodology
Transparent waits, not fake precision.
Wait Time Radar does not pretend every line has a clean live API. It gives useful planning estimates with visible confidence labels.
Confidence labels
HighRecognized airport code or strong official-directory context.
MediumSearch text clearly names a category or nearby public places are found from open map data.
LowAddress-only or broad search where the category/source is inferred.
Formula
Estimated wait = category baseline multiplied by a time-of-day factor, then shown as a practical range rather than a fake exact number.
Sources
Airport and agency pages link to official sources where possible. Nearby place discovery can use OpenStreetMap/Nominatim/Overpass in the browser and is clearly attributed. Passport agency context points to Travel.State.gov. TSA, CBP, DMV, clinic, and passport conditions can change quickly.
