We have developed a traffic simulation model to quantitatively assess the resilience of a twin-tube motorway tunnel in the event of traffic accident or fire occurring within a tube. The motorway section containing the tunnel was investigated for differen...

This paper presents a preliminary assessment of road tunnel safety issues among respondents?specifically, real and potential users of road tunnels. We recruited a group of respondents to study their knowledge of evacuation procedures and awareness of saf...

We have set up a Computational Fluid Dynamics (CFD) modeling, and performed a user evacuation model, for evaluating the risk level in one-way road tunnel tube when used for bi-directional traffic in particular circumstances. The simulations were carried ...

We performed Computational Fluid Dynamics (CFD) modeling, and simulated a people evacuation process from a tunnel in the event of a fire, for evaluating the potentialities of using, as a temporary safety measure, an emergency vehicle equipped with a micr...

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 clarifie...

Analysis of the emergency operation modes of tunnel ventilation systems used in subways has shown that these modes do not provide the steady gas-air flows in case of fire in the rolling stock and its stop in the tunnel; and there is no methodological sup...

After tunnel fire catastrophes at the end of the 1990's, the safety at road tunnel operations has become a priority on transportation policies at international level especially inside the European Union. This circumstance has required the analysis and ri...
