Special Issue Information

Dear Colleagues,

This special issue of the journal is intended to document the state of the art in the areas of safety, ventilation and operation of underground infrastructure with a strong focus on traffic and transport systems. The rapid increase in traffic in urban areas means that road traffic moves underground. This is demonstrated, among other things, by major projects in all parts of the world. The positive aspects of better use of valuable urban areas, however, require significantly higher demands on the operation and safety of the underground transport network. The same applies to rail transport. There are currently some large Alpine crossings under construction in Europe, while the tunneling boom in Asia continues. High-speed trains should increase capacity and enable a sustainable route for passenger and freight traffic. However, this also means completely different requirements for the planning and operation of these systems. What applies to rail and road transport is increasingly also true of local public transport. Here, too, there is a clear trend towards moving traffic underground. However, this also means that aspects such as ensuring acceptable air quality and having smoke-free stations in the event of a fire are of great importance to users. Not to be forgotten is the fact that the transition from fossil to renewable energy sources, for example through the use of battery-powered or hydrogen-powered vehicles, places completely new demands on the safe operation of the underground transport infrastructure.All of these topics are to be dealt with in this issue of the magazine and thus present the current state of knowledge to interested readers. Contributions to the state of the art in relation to the planning, construction and operation of subsurface transport infrastructures are just as welcome as contributions with novel concepts.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Infrastructures is an international peer-reviewed open access monthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 1800 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

In case of massive fire incidents in tunnels, ceiling lights are covered by dense smoke, and pedestrians must evacuate in the dark tunnel with almost zero visibility. Nonetheless, the walking behavior in a completely darkened tunnel has not been clarified. In this study, we experimentally attempted to investigate the evacuation loci and assess the stress of evacuees by measuring oxytocin and cortisol concentrations in saliva, heart rates, blood pressures, and responses in a survey questionnaire for a full-scale tunnel. Results indicated few differences in both one- and two-dimensional walking speed. In terms of stress, the group of subjects who felt stress demonstrated a walking speed that is 0.17 m/s slower than the group that did not feel it. In the questionnaire survey, most of the subjects answered that the wall was the most helpful item, followed by the unevenness (bumps) on the white lines on the road. One of the subjects became lost, stating that she could not find the unevenness (bumps) on the white lines. These two factors can be rational guides in a dense smoke environment or a completely dark tunnel scenario. Full article
