- Abstract
- Train delays are often monitored using lag indicators of achieved punctuality levels, but indicators can also be used proactively as lead indicators to help reach a certain level of punctuality. In this paper, two lead indicators – the share of delayed dwell times and the share of delayed run times – are formulated and tested on Swedish commuter train data for the years 2001-2020. Results show that in general a larger share of dwell times are delayed compared to run times, and that the differences between metropolitan areas are substantial. Furthermore, results indicate that no more than 25 % of dwell times and 3 % of run times can be delayed if operations are to reach 95 % overall punctuality. Results also show that both dwell time and... (More)
