The Urban Menus algorithm is a novel approach to support stakeholders in urban/regional development projects by providing a 3D planning view combined with a smart analysis framework. Users can choose objects and walk around into the digital tool. The real-time impact analyses displayed integrates ecological, social, and economic considerations from different perspectives, enabling impact oriented as well as participatory approaches.

This paper presents the methodology when applied to early-stage urban/regional development projects allowing users to identify potentials and visions paving the way for next steps.

The impact analyses are based on a dynamic system of quantitative and classified parameters that can be combined and aggregated into impact indicators e.g. expressing qualities to be achieved for a planning area: Happiness, safety, innovation, profitability, and circularity.

The system includes a list of currently already more than 100 parameters that align with the EU Green Deal, UN-SDGs, Leipzig Charter, Biodiversity 2030 targets and aspects of diversity and gender.

The paper highlights the novel key features of the Urban Menus algorithm:
1. Simplify Decision-Making: The algorithm “quick snoop” uses a simplified scale of small, medium, and large to evaluate a short list of parameters, making it intuitive and easy to understand impacts and their relation to scenarios.
2. Use meaningful weighting: The algorithm focuses on the value of planning options for different target groups (age groups) by using “person hours benefits”
3. Focus on the educational process: the method comes with an educational path that involves smart graphical representations to enable equal involvement of stakeholders

The paper goes beyond theoretical analysis also presenting the results of pilot projects, demonstrating the effectiveness of Urban Menus in supporting sustainable urban/regional development. The ability to improve decision-making and enhance stakeholder participation makes it a valuable tool for urban planners, developers, policymakers and the according educational sectors.
