Abstract

We present an empirical study of recovery times from disruptions due to natural hazards and extreme events on the highway system of British Columbia, Canada. Data was obtained from archives of the DriveBC traveller information system. We estimated a proportional hazard model to model recovery rates and ascertain the effects of key factors on recovery rate. The recovery rate for disruptions due to flooding is slowest, avalanche is fastest, and those for wildfires and landslides are similar. Geographic variations were indicated, with longer disruptions observed in more remote regions. Disruptions involving full roadway closure showed longer recovery rates. This study provides empirically-based insights towards improved mitigation of future highway disruptions due to natural hazard events. Given the relatively widespread existence of traveller information systems throughout North America, our analysis approach can be applied to understand transportation system recovery times for, and resilience against, disruptive events of concern in these jurisdictions.

期刊介绍： Transportation Research Part D: Transport and Environment focuses on original research exploring the environmental impacts of transportation, policy responses to these impacts, and their implications for transportation system design, planning, and management. The journal comprehensively covers the interaction between transportation and the environment, ranging from local effects on specific geographical areas to global implications such as natural resource depletion and atmospheric pollution. We welcome research papers across all transportation modes, including maritime, air, and land transportation, assessing their environmental impacts broadly. Papers addressing both mobile aspects and transportation infrastructure are considered. The journal prioritizes empirical findings and policy responses of regulatory, planning, technical, or fiscal nature. Articles are policy-driven, accessible, and applicable to readers from diverse disciplines, emphasizing relevance and practicality. We encourage interdisciplinary submissions and welcome contributions from economically developing and advanced countries alike, reflecting our international orientation.
