The project progressed through conceptual development, method development, empirical fieldwork and comparative governance analysis.
A meta-narrative review of 119 publications identified six recurring, non-hierarchical modes of public interaction: withdrawal, co-presence, co-attention, co-exchange, co-action and assembly. It also identified four dimensions for interpreting conditions associated with interaction: spatial, normative, perceptual and political. This established the conceptual framework for the empirical research and resulted in a peer-reviewed publication in the Journal of Environmental Psychology.
The project then developed Interaction Mapping, shifting the focus from broad activity categories towards the interaction event as the main unit of analysis. An initial protocol translated the six modes into observable indicators and recorded spatial location, duration, composition and transitions. It was tested through paired observation with a trained research assistant. Differences between observers were used to refine event definitions, coding rules and recording procedures. The methodological work combined an interaction recording chart, targeted tracking and a linked user questionnaire.
Following ethics approval, the refined method was applied in three cases in Amsterdam and Rotterdam. The Dutch fieldwork combined systematic observation, spatial mapping and tracking with linked user questionnaires, providing the main setting for calibration and comparison between observed conduct and users’ own accounts. The empirical scope was then expanded to six cases across four Swiss cities and six cases across four UK cities. In total, the project applied the evolving approach across 15 public-space cases in 10 cities and three countries, allowing it to be examined across different spatial forms, management arrangements and planning contexts.
A research visit to ETH Zurich’s Centre for Research on Architecture, Society and the Built Environment (ETH Wohnforum – ETH CASE) supported Swiss data collection and interdisciplinary collaboration on analysis and methodological refinement. The international fieldwork also created opportunities for exchange with researchers and practitioners in the countries studied.
In parallel, comparative governance research examined how POPS are created, regulated, managed and overseen. It developed a lifecycle perspective covering the creation of public obligations, implementation and codification, everyday management and use control, and longer-term oversight and adaptation, and identified recurring governance model families across international cases. The action produced a published cross-disciplinary framework for public social interaction, a developed and field-tested Interaction Mapping approach, comparative evidence from Dutch, Swiss and UK public spaces, and a governance framework for understanding how planning and management arrangements shape public life. Further project manuscripts address Interaction Mapping, comparative youth social life and POPS governance. These outcomes substantially extended the empirical and methodological scope originally envisaged for the project.
