Background & Policy context

Germany has to cope with a high traffic density every day. Thereby tunnels and bridges are important elements of the corresponding road infrastructure which are at the same time highly susceptible to faults. Additionally, they can have a significant function in the overall traffic network flow. It follows that the protection of infrastructural objects within the federal major road network, comprising of 240 tunnels and approximately 39.000 bridges, is a vital goal with respect to the efficiency and the functioning of our infrastructure itself and at the same time to our national well-being.


Threats result from:

  • Terrorism and criminal activities
  • Natural hazards
  • Major accidents

Main protection goals of SKRIBTplus concern:

  • Life
  • Mobility
  • Infrastructure
  • Supply of private households and the economy

The interdisciplinary composition of the consortium reflects the variety of these challenges. The central challenges in SKRIBTplus, resulting from the aforementioned protection goals, are:

  • Security and safety of the users
  • Protection of infrastructural objects
  • High availability of infrastructural objects

In SKRIBTplus innovative protection technologies are developed and demonstrated on selected objects. Thereby, the focus is on:

  • Construction engineering: Innovative construction materials and structures
  • Operational engineering: Innovative detection and control technologies
  • Organization: Optimized incident management

Additionally, protection measures which were already developed within the predecessor project SKRIBT are revised and combinations of different measures are investigated for a potential improvement of their protection effect.

The following list is representative for the application guidelines that were developed within SKRIBTplus:

For owners and operators of infrastructural objects:

  • Automatic structural assessment for bridges in case of explosions
  • Simplified assessment rules
  • Workshop for infrastructure owners for assessing threats and relevant protection measures
  • Method for safety and security related assessment of infrastructural objects
  • Guide for quick safeguarding of load-bearing structures
  • Manual “Security-Risk-Management”

For first responders:

  • Guideline crisis management

For users:

  • Guide for improving the behaviour of the user

Findings of the study are published in detail by several final reports of the project partners (German only) which are available online via the German National Library of Science and Technology (TIB):
