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

التعريف

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

الصيغة

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.

الوحدات

kilometres per hour, with the count of trips

الفئة المشمولة

Trips that reached both ends of a segment between two consecutive timepoints, from settled final predictions.

نافذة القياس

The 28 most recent completed service days, by calendar date in Ottawa.

التغطية

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.

أهلية النشر

Segments shorter than 300 metres or 1 minute are not measured. A segment needs at least 20 trips before a speed is shown.

النطاق

Every bus route segment with enough trips, by the same hour bands as bunching.

ما الذي يمكن أن يدعمه هذا الرقم

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.
