January 2020 - 60 articles

Cover Story: The cover image shows a 3D point cloud of a damaged building in Lyon, France, calculated from stereo imagery obtained with a consumer UAV/drone (DJI Phantom 3, inset) in the context of a European-funded research project (INACHUS, www.inachus.eu). The project focused on the development of methods to support first responders in search and rescue activities following accidents or disasters. The image illustrates the use of UAV in detailed scene reconstruction, and how the derived information together with advanced machine learning are used for structural damage detection, superimposed in red on the model. The article provides a detailed review of how UAV have been used in structural damage assessment.View this paper.

An Efficient Staged Evacuation Planning Algorithm Applied to Multi-Exit Buildings

  • Litao Han,
  • Huan Guo,
  • Haisi Zhang,
  • Qiaoli Kong,
  • Aiguo Zhang and
  • Cheng Gong

When the occupant density of buildings is large enough, evacuees are prone to congestion during emergency evacuation, which leads to the extension of the overall escape time. Especially for multi-exit buildings, it’s a challenging problem to afford a...

  • Qing Zhai,
  • Wei Wang and
  • Yijie Zhang

Mapping the fine-scale spatial distribution of emergency shelter demand is crucial for shelter planning during disasters. To provide shelter for people within a reasonable evacuation distance under day and night disaster scenarios, we formed an appro...
