Key Findings
- 01Experimental logics in urban transformation are not static but emerge and shift over time.
- 02The interplay between different street experimentation platforms reveals dynamics of both complementarity and competition.
- 03Municipal actors are critical for implementation and scaling, but their capacity for transformative change can be limited.
- 04Learning between different street experiments is often missed, hindering broader transformative potential.
Application
Design takeaway
Design projects focused on urban transformation should adopt a longitudinal perspective, anticipating how interventions will evolve and how different stakeholders will interact over time.
How to apply
When planning urban interventions, map out the potential stakeholders, their evolving interests, and how different experimental approaches might interact or compete over time. Plan for mechanisms to capture and disseminate learnings between projects.
Project actions
- 01Consider how your design project might evolve over time and adapt to changing user needs or environmental factors.
- 02Think about who else is working in the same space and how your project could complement or compete with their efforts.
Method & Evidence
Variables
Strengths & Limitations
Strengths
- +Longitudinal perspective over a decade.
- +Combination of document analysis and interviews provides rich qualitative data.
- +Focus on a specific city allows for in-depth analysis of local dynamics.
Limitations
The specific context of Stockholm might not fully represent other cities. The 10-year timeframe might not capture all long-term evolutionary aspects.
Reliability & validity
Reliability could be enhanced by using multiple coders for document analysis and interview transcripts. Validity is strengthened by triangulating data from documents and interviews, and by the longitudinal perspective.
Think critically
To what extent can municipal actors truly drive transformative change in urban environments, or are they primarily facilitators of change initiated by other stakeholders?
Design Principles
"Urban interventions should be designed as part of an evolving system, allowing for adaptation and learning across multiple projects and stakeholder groups."
Understanding the evolutionary trajectory of urban interventions is crucial for designers and urban planners. It highlights how initial experiments can pave the way for more significant changes, and how the success of these transformations depends on the dynamic relationships between various stakeholders and the strategic adaptation of experimental approaches over time.
What This Means for Your Design
Street experiments change over time because the people involved have different ideas and goals, and how these experiments work together affects their success.
