- High-frequency excess predicted wait
The difference between waiting time implied by settled predicted arrival spacing and waiting time implied by scheduled spacing for eligible high-frequency route–stop hours.
- Definición
- The difference between waiting time implied by settled predicted arrival spacing and waiting time implied by scheduled spacing for eligible high-frequency route–stop hours.
- Fórmula
- Predicted EWT − scheduled EWT, where each EWT = Σ(gap²) ÷ (2 × Σ(gap)). Gaps are ordered independently for scheduled and predicted arrivals before aggregation.
- Unidades
- seconds, displayed in minutes
- Población
- Eligible high-frequency bus route–stop hours with ordered scheduled and settled predicted arrivals.
- Ventana de medición
- Eligible completed service days in the latest 30 days.
- Cobertura
- Only service days that pass prediction-matching quality are included; every result retains its matched-arrival and stop counts.
- Elegibilidad para publicar
- At least five matched arrivals in a route–stop hour and an average scheduled headway from two through twelve minutes.
- Alcance
- Completed service days in the latest 30 days that satisfy the prediction-matching quality threshold; route–stop hours require at least five matched arrivals and an average scheduled headway from two through twelve minutes.
- Qué puede respaldar este número
- Difference in wait implied by predicted spacing versus scheduled spacing. It is not observed passenger wait, actual door-opening regularity, or a low-frequency punctuality measure.

Exclusiones
This is not an observed passenger-wait survey, and it does not include low-frequency route–stop hours or rail without supported realtime observations.
A negative result is not labelled better service; it only means the predicted spacing implied less wait than the imported timetable for the eligible population.
Incertidumbre e interpretación
Predicted arrivals are the last supported predictions near scheduled time, not recorded door-open events. Feed and matching quality therefore remain attached to the result.
