“…Lei et al (2021) and Li et al (2021aLi et al ( , 2021bLi et al ( , 2021c investigated the effect of the fire locations on the maximum exceedance temperature through experimental and theoretical studies in branched tunnel fires. Lu et al (2022a) indicated that the maximum exceedance temperature of the fire in the bifurcation area was slightly higher than that of the fire located in the non-bifurcation area under longitudinal ventilation. Lu et al (2022b) proposed an empirical model for the maximum ceiling temperature in the bifurcated tunnel under different fire locations with bifurcation angle between 20 • and 90 • .…”

“…The investigation of natural ventilation in tunnels is crucial, as it is often necessary to address system design problems. Lu et al [76] presented a case study that focused on the effect of ceiling temperature under natural ventilation in a tunnel. The results showed that the maximum temperature reached was independent of the fire location and bifurcation angle.…”

Fire tests are used to determine whether fire protection products meet the minimum performance criteria set out in codes and legislation, as well as to certify these products. Experimental large-scale fires are used to test the performance of safety systems in tunnels, which are confined environments with a high probability of accidents and significant consequences due to the evolution of the event and whether there is the capability of counteracting it by safety measures. In this study, we conducted a systematic literature review following PRISMA guidelines. We searched the Scopus and Web of Science databases for publications from 2013 to 2022, resulting in a selection of 72 articles. An analysis was conducted on the following main topics: tunnel fires, fire characteristics (measured variables, spread, and smoke), model-scale tests, automatic shutdown systems, and ventilation solutions. One of the most important contributions of this study is the suggestion that fire tests represent an effective method not only to prevent fire events in tunnels but also to ensure the resilience of the infrastructure. Based on this state-of-the-art literature review, future tunnels could be designed by linking new smart technology and artificial intelligence to create interactive and high-performing safety systems.
