Decision-making in participatory urban development

Abstract

Citizen participation has become an important component of urban development, as spatial interventions directly affect the daily lives of residents and often involve competing interests. Although participation is intended to incorporate citizens’ values, concerns, and preferences into planning processes, many participants perceive a disconnect between their input and final decisions. This gap is frequently described as a “black box”: an invisible process in which citizen input is interpreted, weighed, and translated into planning outcomes by experts and political actors. At the same time, Virtual Reality (VR) is increasingly used in participatory planning to improve communication and understanding of spatial proposals. However, limited knowledge exists about how citizens’ values are balanced against other considerations and how this process is reflected in VR models.

This study examines how the weighing process of citizens’ values can be made more transparent in order to better safeguard these values within VR-supported participatory urban development. A qualitative case study was conducted in a Dutch municipality involving a road infrastructure and housing development project. Data were collected through a literature review, semi-structured interviews with residents and experts, and exploratory VR sessions.

The findings show that the weighing of values is shaped by the interaction between a project arena, institutional and political arena. Within these arenas, citizen values are continuously balanced against broader considerations such as policy objectives, political priorities, feasibility constraints, risk management, and project ambitions. Rather than representing a neutral translation of participation outcomes into spatial interventions, decision-making emerges as a dynamic process in which values are negotiated, prioritised, and sometimes transformed. This process gives rise to procedural value conflicts concerning transparency, fairness, trust, and influence. While citizens often express concerns about substantive issues such as traffic safety, accessibility, and liveability, dissatisfaction is frequently rooted in perceptions of limited influence over decision-making and uncertainty about how trade-offs are made.

In response to these tensions, experts adopt different strategies ranging from deliberative dialogue to more strategic and technocratic approaches. While these strategies are often intended to manage complexity and maintain project progress, they can simultaneously reinforce procedural tensions and contribute to perceptions of exclusion. The study concludes that VR can contribute to transparency by making trade-offs, constraints, and alternative scenarios more visible. However, VR should not be regarded as a neutral tool. Because decisions about what is visualised and what remains invisible are themselves shaped by institutional and political considerations, VR can also function as a strategic instrument that influences how decisions are perceived and legitimised. Transparency therefore requires making not only design outcomes visible, but also the decision-making processes through which they are produced.
