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.

由于自然灾害事件造成的高速公路中断的恢复时间

本文对加拿大不列颠哥伦比亚省高速公路系统因自然灾害和极端事件而中断的恢复时间进行了实证研究。数据来自DriveBC旅客信息系统的档案。我们估计了一个比例风险模型来模拟回收率，并确定了关键因素对回收率的影响。洪水造成破坏的恢复速度最慢，雪崩造成破坏的恢复速度最快，野火和山体滑坡造成破坏的恢复速度也差不多。地理差异表明，在更偏远的地区观察到的中断时间更长。完全封闭道路的破坏显示出更长的恢复速度。本研究为改善未来因自然灾害事件造成的公路中断的缓解提供了基于经验的见解。考虑到旅行者信息系统在整个北美地区相对广泛的存在，我们的分析方法可以应用于了解交通系统对这些司法管辖区关注的破坏性事件的恢复时间和恢复能力。

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.
