Abstract:

One of the main challenges facing transit agencies is offering reliable service with minimum number of interruptions and ensuing delays. Although this issue has recently emerged as a top priority in many cities, there has been little research effort to investigate issues surrounding service disruption. As a response to this gap, this study aims at understanding the impact of outdoor track segments (or open-air sectors) of the subway system and weather conditions on the number of service interruptions and the magnitude of resulting delays at the stop level. The study uses detailed subway system interruption data collected in 2013 by the Toronto Transit Commission (TTC), the public transit provider in the City of Toronto, Canada. Descriptive statistics and statistical models are developed for the purpose of the study. The empirical investigation reveals that outdoor tracks have a statistically significant association with subway system’s service interruptions. Longer outdoor track distances are linked to both higher frequencies and delays of service interruptions. Weather conditions, in terms of the amount of snow on the ground and rainfall interactions with outdoor tracks, have also a significant association with the frequency and duration of service interruptions. The paper results provide policy makers and planners with useful policy-relevant information related to the impact of outdoor tracks and weather conditions on the subway system interruptions that could be used to support higher capital investments when planning rail transit systems to achieve the system resilience.
