Background & Policy context

An effective and secure road network is essential in order to guarantee mobility and supply for the whole population. Particularly bridges and tunnels are key elements of the road network. Restrictions of the availability of these infrastructures may lead to intense traffic interferences on the surrounding road network resulting in negative impacts on the road user, high economic follow-up costs and negative environmental impacts.


The aim of the project is at first to identify possible threat scenarios which could directly affect bridges and tunnels and their users. This will be done by considering all kinds of natural and man-made threats (“all-hazard approach“). The effects of the different threat scenarios on the structures and their users are determined and possible protection measures are investigated concerning their effectiveness and efficiency by using risk- and scenario analysis as well as cost-benefit-analysis. The results are effective protection measures which increase the security of road users and ensure a high availability of road infrastructures.

In the SCRIBT project, the effects of damage of infrastructure buildings and their users in various threat scenarios were assessed and compared. For this purpose, calculations on fire, smoke and harmful gas emissions as well as explosions were carried out. With risk and scenario analysis as well as cost-benefit analysis, suitable protection measures were assessed regarding their effectiveness. In addition, the researchers have drawn up a guide on "Incident management for road tunnels", which aims to sensitize the responsible institutions and emergency services for extreme scenarios.

Findings of the study are published in detail by several final reports of the project partners (German only) which are available online via the project website:

A video about how to behave in tunnels (German only) is available via:
