Calculation method
Calculation method
Median speed (km/hour)
Linear-interpolated sample quantiles and population standard deviation; not speed-limit selection.
85th percentile speed (km/hour)
Linear-interpolated sample quantiles and population standard deviation; not speed-limit selection.
Population standard deviation (km/hour)
Linear-interpolated sample quantiles and population standard deviation; not speed-limit selection.
Symbols and units

- Observed spot speeds (km/hour)
Use the units shown. A list keeps the order in which you enter its values. The symbol ^ means “raised to the power of”.
Assumptions & limits
Assumptions & limits
- User-supplied measurements and assumptions; Linear-interpolated sample quantiles and population standard deviation; not speed-limit selection. Supported limits: Finite numeric values bounded to 1e9 magnitude; lists and tables contain 1–100 records unless a stricter bound is stated. Inputs use the units shown. Lists explicitly paired by a method must have matching lengths; independent polynomial coefficient vectors may differ. Respect stated physical, interpolation, policy and computational domain limits.
