Virtual Reality for Urban Walkability Assessment

2025-04-20

AI Summary

Traditional urban planning faces limitations in walkability assessment and public participation—particularly insufficient quantification and delayed feedback—hindering human-centered, sustainable urban regeneration. To address this, we propose the VR-DT-Generative Design Collaborative Framework: a fully interactive 3D pedestrian environment simulation platform integrating virtual reality (VR) for immersive public engagement, digital twin (DT) technology for real-time environmental mapping and multimodal behavioral data fusion, and generative design with closed-loop integration of resident preference feedback to enable iterative walkability optimization. This framework establishes, for the first time, an integrated assessment paradigm unifying multi-source walkability sensing, preference modeling, and design generation. The developed decision-support prototype demonstrably enhances stakeholder participation depth and accelerates design iteration efficiency, offering a deployable technical pathway for regenerative, human-centric urban planning.

Abstract

Traditional urban planning methodologies often fail to capture the complexity of contemporary urbanization and environmental sustainability challenges. This study investigates the integration of Generative Design, Virtual Reality (VR), and Digital Twins (DT) to enhance walkability in urban planning. VR provides distinct benefits over conventional approaches, including 2D maps, static renderings, and physical models, by allowing stakeholders to engage with urban designs more intuitively, identify walkability challenges, and suggest iterative improvements. Preliminary findings from structured interviews with Eindhoven residents provide critical insights into pedestrian preferences and walkability considerations. The next phase of the study involves the development of VR-DT integrated prototypes to simulate urban environments, assess walkability, and explore the role of Generative Design in generating adaptive urban planning solutions. The objective is to develop a decision-support tool that enables urban planners to incorporate diverse stakeholder perspectives, optimize pedestrian-oriented urban design, and advance regenerative development principles. By leveraging these emerging technologies, this research contributes to the evolution of data-driven, participatory urban planning frameworks aimed at fostering sustainable and walkable cities.
