Bus service punctuality

The York Enhanced Partnership publishes a monthly measure of bus service punctuality in the York area.

The published measure is calculated using timings from every bus service in the York area for which real-time information is available. The measure provides a picture of overall punctuality across all routes in York over the last 12 months:

Method

For every journey on each bus service, the schedule deviation (the difference between the timetabled 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 - average schedule deviation less than 4 minutes.
Outstanding - average schedule deviation less than 2 minutes.

Major factors affecting bus punctuality over the last 12 months:

August 2024 – congestion due to York Races and Blossom Street signals trial
September 2024 – lane closure on A64
Octocber 2024 – congestion around York Rail Station due to major works
November and December 2024 – heavy traffic due to Christmas Markets
February and March 2025 – major utility works on Fulford Road and Clifton Green
April 2025 – various road closures due to burst water mains
