How fast buses actually moved between two consecutive timepoints of a route, next to the speed the timetable planned for the same segment.

Definição
How fast buses actually moved between two consecutive timepoints of a route, next to the speed the timetable planned for the same segment.
Fórmula
Segment ends are the stops the timetable marks as timepoints. When it marks every stop, the trip is cut about every 1 kilometre. Observed time = arrival at the end minus arrival at the start. Speed = distance times trips divided by total time, in kilometres per hour. Slow trip: took at least 1.5 times the scheduled time.
Unidades
kilometres per hour, with the count of trips
População
Trips that reached both ends of a segment between two consecutive timepoints, from settled final predictions.
Janela de medição
The 28 most recent completed service days, by calendar date in Ottawa.
Cobertura
Only days the daily rollup computed. Days with partial feed capture and days when the live trip numbers did not match the timetable are left out and listed.
Elegibilidade para publicação
Segments shorter than 300 metres or 1 minute are not measured. A segment needs at least 20 trips before a speed is shown.
Escopo
Every bus route segment with enough trips, by the same hour bands as bunching.
O que este número pode sustentar
Compare the observed speed with the scheduled speed on the same segment. Distance is a straight line between stops, so both speeds are lower than the road speed.

Status da implementação

Fonte candidata
Implementado neste candidato de código-fonte.
Produção pública
Esta versão da métrica não foi verificada de forma independente na implantação pública em produção.

Leia o status antes de citar este número.

The daily calculation is implemented in this source candidate (worker rollup, migrations 0396 and 0407, method settled-reliability-patterns-daily-v2). Public production verification for this version is not yet recorded.

Exclusões

OC Transpo O-Train lines are left out: the operator publishes no live train positions, so their arrivals repeat the timetable.

Times over 4 times the schedule plus 10 minutes are treated as data errors and left out. A stop a trip visits twice is never a segment end.

Incerteza e interpretação

Arrival times are the last prediction made no earlier than 10 minutes before the scheduled time, not a recorded door opening.

Distance is the straight line between stops along the trip, not the road, so speeds are lower than true road speeds. Use them to compare segments, not to check speed limits.
