SKRIBT - Protection of critical bridges and tunnels in a road network
Overview
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.
Objectives:
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.
