The availability and functionality of transport infrastructure is essential for the mobility of people and the transport of goods. It enables social participation, the maintenance of supply and disposal services and further prosperous economic development in our globalised society based on the division of labour. However, motorways and trunk roads in particular are subject to very high levels of pollution. In particular, the further increase in freight traffic creates immense maintenance, expansion and modernisation requirements.
In addition, there is an additional need for adaptation due to the changes to be expected as a result of climate change. If necessary maintenance measures are not carried out in time, this can lead to traffic restrictions on individual routes or even to the failure of infrastructure elements such as bridges. Necessary major construction measures not only entail a high investment requirement, but also lead to traffic restrictions due to the associated construction sites.
