LED Lighting in ASFINAG Road Tunnels

The article explains the current standing of LED technology, in addition to the pros and cons of these lighting systems. Furthermore, the article aims to show the influence of better quality lighting systems on drivers. Therefore, it presents information of real-life field tests in tunnels with different lighting systems.

Alternative Fuels and the Future of Road Tunnels and Road Tunnel Design

This article explores changes that will result from the use of alternative fuels in road tunnels (and potential consequences regarding events occurring in road tunnels).

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.
