Method of recording bus service punctuality
For every journey on each bus service, the schedule deviation - the difference between the timetable departure time and actual departure time - is recorded at each timing point - a stop where buses are required to wait until the timetabled departure time if they arrive early.
An average of all the recorded times is then calculated, 5 times per day, for the following time periods:
- Morning: 00:00 to 06:59
- AM Peak: 07:00 to 09:29
- Intermediate: 09:30 to 14:59
- PM Peak: 15:00 to 17:59
- Evening: 18:00 to 23:59
The reported punctuality figure for each month consists of the percentage of measure periods during that month where punctuality is:
- Good: An average schedule deviation of less than 4 minutes
- Outstanding: An average schedule deviation of less than 2 minutes
