ISTSS 2020 - Program

The 9th International Symposium on Tunnel Safety and Security (ISTSS) was held as an online event 5 - 7 May 2021.

ISTSS is now well established in the tunnel fire community and the success of ISTSS is a tribute to the pressing need for continued international research and dialogue on these issues.

The Proceedings include 42 papers and 13 extended poster abstracts. The online event includes 35 paper presentations and a poster session with 10 posters. You find more information about Proceedings ISTSS 2020 under Publications on the right hand side.

ISTSS 2020 Best paper
Experimental study of backlayering length and critical velocity in longitudinally ventilated tunnel fire with wideshallow cross-section
By: Tianhang Zhang, Ganyu Wang, Kaijie Wu, Yadong Huang, Kai Zhu and Ke Wu

This paper presents very nice experimental and theoretical work on critical velocity and backlayering length, which largely verifies previous important findings. The authors show a high level of scientific knowledge in the subject and obtain interesting improvement of original work.

ISTSS 2020 Best poster
Current status of international tunnel standards and guidelines for water-based Fixed Fire Fighting Systems
By: Tim Usner and Armin Feltmann

The winners used the poster format in a good and balance way. It is appealing, clear, easy to access and easy to follow.
