Superblocks are traffic-calmed neighborhoods that contribute to climate change mitigation and improve living and health conditions of inhabitants without requiring extensive reconstructions. This article investigates experiments with superblocks in Vienna (Austria) from initial discussion to the first experimental implementation. We use an integrated mixed-method approach: First, we examined potential climate and health benefits of three hypothetical superblock sites through transport modeling. We then conducted stakeholder interviews at two points of time to investigate the perceived acceptance of superblocks and to examine how superblock experiments align with the conventional planning regime, thereby focusing on actor's composition, dominant discourses, and mode of governance. The modeling results suggest that reductions in greenhouse gas emissions and public health benefits are 2–3 times higher when superblocks are implemented in more deprived compared to more affluent urban areas. In the course of implementing the first superblock experiment in Vienna, the discursive reframing of superblocks as a redistributive intervention, which we could trace through the interviews, resulted in implementing the pilot project in a district with the most beneficial sustainability outcomes.

维也纳超级街区实验如何影响气候和健康结果并与城市规划制度相互作用

超级街区是交通平静的社区，有助于缓解气候变化并改善居民的生活和健康条件，而无需进行大规模重建。本文研究了维也纳（奥地利）的超级区块实验，从最初的讨论到第一次实验实施。我们采用综合混合方法：首先，我们通过交通模型研究了三个假设的超级街区地点的潜在气候和健康效益。然后，我们在两个时间点进行了利益相关者访谈，以调查对超级区块的接受程度，并研究超级区块实验如何与传统规划制度保持一致，从而重点关注参与者的构成、主导话语和治理模式。建模结果表明，与较富裕的城市地区相比，在较贫困的城市地区实施超级街区时，温室气体排放量的减少和公共健康效益要高出 2-3 倍。在维也纳实施第一个超级街区实验的过程中，超级街区的话语重构是一种再分配干预措施（我们可以通过访谈追踪这一点），从而在一个具有最有利可持续性成果的地区实施试点项目。
