Wie nutzen Sie Daten und Evidenz, um Ihre städtebaulichen Entscheidungen zu treffen und Ihre Ergebnisse zu bewerten?

While data can help to identify new opportunities and existing challenges, it must not be the only determining factor in design decisionmaking. Consider the validity of the data sources, challenge potential biases in research methodologies, and evaluate the currentness or staleness of the data. Urban designers also fall prey to confirmation bias in both research and presentation. Like any good scientist, consider the “null hypothesis” and be transparent when sharing to the public.

To inform urban design decisions, we can start by collecting diverse data (demographics, traffic, land use) and engaging with the community for their feedback. We then analyze this data using tools like GIS to predict the impacts of our designs. We must establish clear performance indicators (e.g., air quality, and public space usage) to evaluate outcomes. After implementing our designs, we continue to monitor these indicators, analyze the impacts, and adjust our designs based on our findings. Sharing the results with stakeholders helps validate the effectiveness of the design. This approach, grounded in data and community input, ensures sustainable urban development.

I like the contribution from Alexander. Should this be about data or people? Urban design is a blend of both! Data analysis provides a foundation: demographics, traffic flows, noise levels. But it's just the start. Observing how people use and interact with spaces is crucial. Watch pedestrian patterns, see which areas attract crowds, and identify underutilised zones. This user-centered approach helps you design spaces that truly meet people's needs and encourage positive interactions within the urban environment.

Demographics: Who are you designing for. Use census data or surveys to learn age, income, and household size. Helps tailor housing, amenities, and infrastructure needs. GIS: These provide spatial data. Analyze floodplains, wind patterns, and natural resources to optimize land use and promote sustainability. Traffic & Transportation Data: Look at existing traffic patterns and consider future needs. Will you need robust public transport? This data informs road design and promotes walkability. Public Engagement & Surveys: Don't forget to ask your audience! Gather resident feedback on needs and preferences through surveys, workshops, and forums. This fosters a sense of ownership and ensures the design aligns with community desires.

Using data is integral to evidence or performance based design. Still a bit of a black art especially for architects and urban designers who tend not be numerically prepared to interpret or utilise the data. Designers are trained to address the design brief but tend to be ill-equiped to develop the business case that precipitates the design brief or 'problem statement' for the designers. Assemble the right team, technically and otherwise.

Data must not be the end-all-be-all. How often do we make “data-informed design decisions” for communities that are not our own? Community members carry with them lived experiences and can offer a much fuller perspective into urban design opportunities. How valid is big data if we only are capturing a fragment of information? Would you choose to trust a contractor to build your house if they only skimmed the blueprints? Do not let rationalism be the only paradigm you follow as cities are living and breathing entities. After all, what makes a public space or neighborhood special is often serendipitous and magical.

Economic appraisal frameworks have long been used by government bodies to drive investment decision making for transport and other municipal projects. Some aspects are fairly well documented with refinements built up over the years. They are generally based on developing an overarching Benefit : Cost ratio as part of a 'traffic light' multi-criteria analysis that includes strategic, policy and other criteria. Having said that, there are a lot of social and environmental benefits that are still difficult to capture numerically and may need to be safeguarded 'politically' to ensure a balanced result. Extremely vulnerable when money is short.

Data: never enough of it. But its no good if there are no appraisal frameworks in place to produce actionable insights and forecasts. And thats only the start. After identifiying the need, there will be a lot more work to establish the 'sweet spot' where the best benefit bang for your buck lies. Along the way, a lot of work would also be needed to identify synergies, reduce risk, cost and programme whilst delivering that optimised product.

Implementing data-driven design decisions is the next logical step for urban design. Algorithms running on user data can generate factual feedback about city planning in real time to inform better policy-making and ensure higher resource efficiency. This approach is being implemented in cities like Rotterdam, Shanghai, and Copenhagen, where these insights help manage resources more effectively, reduce environmental impact, and plan for climate resilience. By leveraging data, planners are better understanding traffic patterns, environmental impacts, and social behaviors, leading to more informed and practical solutions. Importantly, this approach minimises the guesswork and reduces costs, a significant benefit for any urban planning project.

Data and Evidence indicate we are doing a poor job of raising emotionally healthy little boys. Our prisons are full of men, who through no fault of their own, had the misfortune of being born into a "community" of inattentive /absent-minded / poorly prepared adults. Children thrive in community and wither in aloneness. We would be better served by designing communities / villages where we are encouraged, by design, to socialize. Fences are for dogs. One swimming pool with swings and a grassy hill to roll down, shared by your neighbors. Children need to feel like they belong, that they are seen and valued, not just to their nuclear family but, to humanity.

Leadership must come from those with experience in conventional real estate development as well as manufacturing to ensure that solutions meet market demands and fit into community, site environment and user expectations! Speed and low cost are not enough!
