Alarge percentage of the existing transportation infrastructure was designed based on the knowledge and experience of decades past. In the meantime, transport and traffic have grown considerably in volume and has also changed in terms of its composition. Consequently, the safety level in much of the existing infrastructures has often decreased in cases where no intermediate measures were taken to cope with the changes in quantity, type and loading of vehicles and rolling stock.
