The project focused on the planning of necessary retrofitting and/or replacement measures for the bridges concerned. The project builds on the results of a completed previous 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 ongoing project the method is being further developed with the aim of applicability for larger sub-networks. The aim of the project is then to develop a software prototype for the calculation of optimized retrofitting programs.
