Lineare Infrastrukturlandschaften im Wandel: Perspektiven für eine blau-grüne Transformation von Stadtstraßen und kanalisierten Gewässern

In this publication, the interdisciplinary research network LILAS (Linear Infrastructures in Transition) outlines interdisciplinary perspectives on and conceptual planning and design approaches for the further development of canalised water bodies and urban roads for a sustainable transformation of linear infrastructures in urban spaces. The discussion paper documents an interim status of the ongoing research project.

The publication first describes the thematic focus, the understanding of the subject as well as the status quo and the context of its development in order to summarise essential factors for the planning and transformation of blue (canalised water bodies) and grey (urban roads) infrastructures. In addition to presenting selected guiding principles of planning as well as guidelines and specifications for the design of roads and water bodies, key challenges for the transformation of these spaces are also identified. Conceptual reference points for the analysis of transformation are the Multi-Level-Perspective Model (MLP) and the socio-ecological-technical systems (SETS) model, which are applied to the spatial context of linear infrastructures.

The authors build on these foundations and derivations by developing cross-sectoral perspectives on the spatial transformation of linear infrastructures. Through the guiding principles of multifunctionality and multicoding, the necessary technical requirements are to be considered in an integrated way with social usage patterns and resilience-increasing ecological measures for linear infrastructures.

An overarching typology of urban infrastructure corridors describes their central functions and the subspaces with their specific core tasks. Three possible spatial transformation approaches for urban roads and canalised water bodies round off the analysis - illustrated by examples from international practice. The spectrum ranges from selective individual measures to transformed spatial divisions in infrastructure corridors to the fundamental transformation of entire areas.
