What is Public Performance Measure mean?
The public performance measure (PPM) is a measure of the punctuality and reliability of passenger trains in Britain. It is the percentage of scheduled trains which successfully run their entire planned route, calling at all timetabled stations, and arrive at their terminating station 'on time', where 'on time' means within five minutes of the scheduled destination arrival time for London and South East and regional operators (i.e. commuter services), or within ten minutes for long-distance operators.
It is the industry standard measurement of performance, and has been used since 6 June 2000.
The target for PPM varies each year and for each train operator, and is agreed with the Office of Rail Regulation. In October 2013 ORR said that, "Network Rail should... ensure that 92.5% of trains arrive on time nationally by 2019 (as measured using PPM), compared to 90.7% today."
