Major transit infrastructure disruptions have become more frequent due to increasing maintenance needs for an aging infrastructure, system failures, and disasters. Understanding travel behavior reactions to service disruptions based on empirical observations is a fundamental step toward planning and operating an efficient and reliable transportation system. Few studies in the literature investigated the behavioral and system impact of transit service disruptions. To bridge this gap in literature, this research investigated travel behavioral reactions to transit service disruptions during the Washington D.C. Metro SafeTrack projects using a unique panel survey. This study will offer new insights on multi-modal, multi-dimensional travel behavioral responses to major transit network disruptions, a critically theoretical prerequisite toward developing and implementing effective strategies (e.g., how to optimally deploy the reserved bus fleet) that minimize system impact and improve transit system reliability and resiliency.
