Air Velocities Permitted in Road Tunnels, and Other Requirements for a Safe Escape Route in Case of Fire
In The Netherlands tunnels are usually equipped with an escape gallery between tunnel tubes, to support evacuation in case of a tunnel fire and/or an incident involving dangerous goods. Overpressure ventilation prevents the smoke from entering the gallery, when emergency exit doors are opened. The article deals with the acceptable air velocity in the escape route and shows the results of tests organized with over a hundred test persons in an actual tunnel.
Lean Tech: How to Reduce the Ever-Increasing Equipment in Modern Road Tunnels?
The article shows how to potentially simplify technical installations without creating new risks, whilst always being adapted to safety requirements.
Influence of Activated Fixed Fire-Fighting Systems on User Behaviour during Self-Evacuation
An important objective of safety measures in road tunnels is to ensure that tunnel users are able to self-rescue in the case of an incident. The influence of fixed fire-fighting systems (FFFS) on the success of self-evacuation of tunnel users has been investigated in a virtual reality (VR) situation and in real tests to establish their effect on the tunnel users' evacuation behaviour.
Provision for Persons with Reduced Mobility during a Tunnel Incident
This article incorporates research and analysis, regarding adjustments to design and operational processes that member countries have adopted in response to the Convention on the Rights of Persons with Disabilities (UN Charter), and their individual National legislation.
Safety Impact of the Physical and Fluid-Dynamic Lengths of a Tunnel
This article focusses on the safety impact of partially open sections, built just before or after the "physical tunnel" . The article provides some scenarios to which the calculation method can be applied.
