The transformation of neighborhoods from car-dominated to people-centered places requires the consensus of multiple stakeholders. Consensus can be built by developing a shared understanding of the local issues, building trust among stakeholders, empowering of local communities to act on their issues, and raising awareness of the long-term impacts of street interventions. The project will develop the StreetForum Toolkit to help urban authorities, citizens, and civic organizations to build consensus around street transformation projects affecting accessibility in urban neighborhoods. It will consist of analog and digital tools that help build consensus and negotiate access and design. We will develop stakeholder personas and narratives representative of street transformation, a collaborative digital crowdsourcing tool, a consensus-making design game, an online street value assessment platform, a physical mobile co-design cart, guidelines for using art installations and cultural events as well as governance guidelines. The toolkit will be tested in four living labs (Brussels, Vienna, Stockholm, and Istanbul) to evaluate its impact, transferability, and scalability. It will be available as free-to-use resources for the broader community.
