The European Project UpTun: Results Of Four
Years Of Research To Improve The Level Of Fire
Safety In Existing Tunnels

Abstract
The European economy relies heavily upon a sustainable transportation system.
In this transportation system, tunnels are a key element. The safety systems in a
significant part of the existing tunnels were designed on the basis of traffic and
its estimated growth of two or more decades ago. It appears however that traffic
has grown more significantly and also changed in composition (more
combustible and flammable goods). Consequently the safety level in existing
tunnels has decreased in cases where no intermediate measures were taken to
cope with the changed supply of rolling stock. This holds throughout Europe, for
road-, rail- and mass-transit tunnels.
The UpTun project main objects have therefore been:
• Development of innovative technologies where appropriate and where
relevant comparing to and the assessment of existing technologies for
tunnel application. Focus is on technologies in the areas of detection and
monitoring, mitigating measures, influencing human response, and
protection against structural damage. The main output is a set of
innovative cost-effective technologies.
• Development, demonstration and promotion of procedures for rational
safety level evaluation, including decision support models; and knowledge
transfer. The main output is a risk based evaluating and upgrading model.
The desired spin-off of the UpTun project would be:
• The restoration of faith in tunnels as safe parts of the transportation
systems;
• The levelling out of trade barriers imposed by supposedly unsafe tunnels;
• An increased awareness of stakeholders for the necessity to develop
initiatives to link all relevant research.
This paper will give an overview of the project and the major achievements.
Keywords: tunnel safety, fire safety, innovative technologies, tunnel upgrading
