The project focused on the planning of necessary retrofitting and/or replacement measures for the bridges concerned. It built on the results of a completed previous project. In the project, a prototypical procedure for the calculation of optimized retrofitting programs has been developed, which minimize the macroeconomic impact of unavailability or limited usability of the bridges in a subnetwork.
The methodology was applied to selected Rhine crossings in North Rhine-Westphalia between Bonn and Duisburg.
In the project, the method was further developed with the aim of extending it to larger sub-networks. Furthermore, a software prototype for the calculation of optimized retrofitting programs was developed.
