Weiterentwicklung der Nutzungsplanung in der digitalen ZeitDie kommunale Nutzungsplanung setzt strategischen Ziele in verbindliche Vorschriften zur städtebaulichen Form und zur angestrebten Nutzung um. Die Digitalisierung ermöglicht heute neuartige Simulationen von urbaner Morphologie und Flächennutzungsmix in 2-D und 3-D welche eine Weiterentwicklung der Nutzungsplanung erlauben.
Lay summary

Europäische Gemeinden und Städte regeln die Flächennutzung auf sehr unterschiedliche Weise und auch innerhalb der Schweiz ist die Diversität immens. Es fehlt jedoch sowohl ein Überblick über die praktizierten Ansätze als auch über die Theorien zur europäischen Flächennutzungsplanung. Dieser Umstand hemmt die Weiterentwicklung der Nutzungsplanung und verhindert die Chancen des digitalen Zeitalters voll zu nutzen. In diesem Projekt befassen wir uns darum mit den folgenden Fragen: 1) Was sind die aktuellen Konzepte und Werkzeuge zur Regelung von Form und Funktion in europäischen kommunalen Nutzungsplänen und wie kann diese Praxis im Kontext der Digitalisierung der Planung weiterentwickelt werden? 2) Wie können wir moderne Simulationsansätze und standardisierte digitale Flächennutzungsplandaten kombinieren, um urbane Morphologie und Flächennutzungsmix in 2-D und 3-D zu simulieren.

Mittels einer Kombination von qualitativen raumplanerischen Forschungsansätzen und räumlich expliziten Modellierungen von Szenarien zeigt das Projekt kritische Aspekte und mögliche Wege in eine Zukunft mit digitaler Flächennutzungsplanung auf.

Abstract

It is widely accepted that spatial planning is the key policy activity to manage the use of urban land. In common multi-level planning systems, municipal land-use planning translates the strategic goals into binding code that regulates urban form and type of land use, i.e. permitted and aspired residential, commercial, industrial, and cultural uses and mix thereof. While land-use planning approaches and tools vary widely across Europe, their diversity and character is surprisingly under-researched and therefore poorly understood. In times of advancing digitalization, this hinders progress in two ways: First, it prevents systematic standardizations of land-use regulations needed for the integration of land-use planning into simulations of land-use change for larger regions. Such modeling efforts support scenario planning for cities and regions and will play a key role in the emerging planning support science. The increasing availability of digital plan data in form of downloadable vector data provides promising opportunities for implementing detailed form and function regulations in urban land-change simulations. However, there is a need for research on the standardization of these regulations and the conceptualizations for the prevailing mixed use. Secondly, digitalization offers new opportunities to overcome the challenges of utilizing traditional 2-D land-use plans to regulate the three-dimensional built environment. As theories on European land-use planning are lacking, the necessary basis for a targeted advancement of practice is missing.With this project, we aim to conceptualize land-use regulation in Europe in times of digital transformation, and based on that, develop tools to integrate land-use regulations, available from digital plans, into urban land-use simulations. We combine research on land-use planning practice with development of urban land-change simulations techniques. Specifically, we address the following questions: 1) What are the current concepts and tools for regulating form and function in European municipal land-use plans and how can this practice be further developed in the context of digitalization of planning? 2) How can we combine state-of-the-art simulation approaches and standardized digital land-use plan data to simulate urban morphology and land-use mix in 2-D and 3-D in land-change scenarios for city regions, i.e. larger scales? A survey will provide a theoretical overview of land-use planning in European countries, while case studies will allow developing a theory-based framework of regulatory approaches and regulations for form and functions that serves as basis for standardization tools. The integration of standardized land-use regulations into urban simulations is tested for selected urban regions in a multi-scenario analysis. Plausible 3-D morphological configurations and mixed land uses are modelled and visualized on a regional scale to assess the feasibility of the approach for planning support. Based on the qualitative and modelling results, theory-based options to address digitalization, standardization and convergence tendencies within land-use planning will be drafted and discussed. The proposed research will identify critical aspects and potential ways ahead into a future with digital land-use planning and advance urban land-change simulation towards more realistic 2-D and 3-D modelling, suitable for scenario analysis and planning evaluation.
