Reconfigurable Roadways: Envisioning the Future of V2X-Driven Autonomous Urban Infrastructure through an Interactive Tabletop Simulator

초록

Autonomous driving and cooperative platooning are expected to transform urban mobility, significantly reducing traffic density in populated cities. Therefore large portions of road infrastructure could become underutilized, presenting valuable opportunities for spatial reallocation. These spaces could host Tactical Urbanism strategies supporting socially adaptive, community-centered urban transformation. We introduce Reconfigurable Roadways (RR) - an adaptive system reallocating road space by expanding pedestrian zones and dynamically modulating vehicle flows through real-time demand. Using V2X-enabled traffic coordination, RR offers a scalable framework for highly flexible, multi-use streets. To illustrate RR and clarify current technology and diverse future possibilities, we present an interactive tabletop simulator of an urban mobility scene. The tangible simulator lets users rearrange modular blocks - each representing a roadway role - to explore near-future scenarios and observe simulated changes in traffic behavior and urban form. The platform fosters intuitive understanding of RR principles and engages users in shaping future urban mobility systems. © 2025 Copyright held by the owner/author(s).
