This dataset provides the Sydney Metropolitan and Outer Metropolitan Bus Service Contract on time running results from 2010 onward.

Until June 2017, Transport for NSW monitored on-time running through monthly surveys conducted over a sample period at the start of the trip.

As of July 2017, PTIPS replaced manual surveys as the source of information for these on-time running results.

The definition of "on time" is provided in the bus contracts which can be found here: https://www.transport.nsw.gov.au/operations/buses-and-coaches/bus-contracts
