Across Europe, a broad number of regions can be identified where the five types of challenges in the field of land-use planning and infrastructure planning as described by NUVit, can be identified. These typologies are the outcome of the three TIILUP/NUVit prologue workshops and an assessment that was made by the core group.
1. Corridor challenges
Large scale infrastructure concentration which is a primary segment of the European Networks. In many situations international (freight) traffic and local traffic are competing for the same space and capacity on the infrastructure.
2. Hub development challenges
Development of Hubs will interlink different modalities. In this way capacity can be exchanged between the different networks and a more stable mobility network is developed. Giving space to hub development can lead to local environmental issues, spatial barriers and negatively impact living qualities.
3. Concurrence challenges
Concurrent growth of a region and an infrastructure corridor often leads to tension. Especially when the infrastructure growth cannot be harmonized with the available space and current spatial form (barrier). In order to create synergistic effects, co-development of infrastructure measures and urban (re)development is required.
4. Consolidation challenges
In some areas, spatial (re)development focuses on the existing urban area. Additional spatial development combined with corridor development can lead to ‘cannibalization’ of the (re)development potential of the existing city. This asks for a consolidation of the corridor in order to maximize spatial quality potential.
5. Transformation challenges
A declining population or economy in formerly booming areas can lead to the situation that the infrastructure lay-out does not fit the land-use anymore. A transformation of parts of the existing, but out-of-use, infrastructure is needed to generate a vital regional future.
