Abstract
The work which is presented in this seminar evaluated options for a key performance indicator that comparably illustrates differences in performance with regard to maintaining service regularity on high frequency routes between urban bus operators. The data used for this study was collected by the International Bus Benchmarking Group, facilitated by Imperial College London, and relates to twelve medium to large sized urban bus operators from different countries. Through two annual rounds of data collection, lessons were learned on feasible data characteristics, required sample size and data cleaning processes. The following four key performance indicator alternatives were tested and their strengths and weaknesses described: 'Excess Wait Time', 'Standard deviation of the difference between the scheduled and the actual headway' and % of service within a fixed and relative number of minutes from the scheduled headway, also referred to as respectively 'Wait assessment' and 'Service regularity'. The results suggest that while all four methodologies illustrate a different, interesting view on service regularity performance, the Excess Wait Time methodology is the best option when the key performance indicator should reflect the customer experience of the regularity of service.
