How we measure →

This is the running reliability measure, not the report-card measure: for each stretch between two stops, how long buses really took against how long the timetable allows, over 26 counted days at all hours. It shows which stretches run behind, not how often. The report-card measure replaces it as soon as it has enough weekdays.

Example: a one-kilometre stretch the timetable runs at 20 km/h takes 3 minutes; if buses averaged 15 km/h it took 4, so 1 minute is lost there.

Would you count on route 51?

No sign-in needed. A vote from a device that is not signed in counts a little less than one from an account, and a person who rates many routes counts a little less on each, so no one voice outweighs the rest.
