AB - In this paper we use large-scale mass transit data to improve the journey time performancemeasurement of urban bus systems. For low frequency bus services, the application of ontime performance (OTP) metrics, particularly the location and number of stops to sample,varies greatly across operators, which can lead to biased estimates. In this paper, we aim toaddress sampling disparity, and propose a new statistically robust sampling scheme to ensurerepresentative, non-biased, and comparable measurement of route level on time performance(OTP) which enables the inclusion of operators with sparse data in benchmarking activities.We use automated vehicle location data and analyse 59 unique low frequency route-directiondata sets from 9 international bus operators. Across all route-direction data sets, an averageof 28% of stops are required to be sampled under the defined sampling scheme to achieve a95% confidence level of sampling the route-level mean within a ± 5% range of accuracy. Byincluding data on additional routes, the analysis can be further refined and generalised toenable progressive improvement of inter-operator comparability and benchmarking.
