GIS-Based Hub Strategy for High-Speed Railway Stations Through City-Hub and Enter-Hub Frameworks- A Focus on West Kowloon Station in Hong Kong

This study proposes a strategic framework for developing West Kowloon Station (WKS) in Hong Kong as an integrated urban hub. It addresses key urban challenges such as spatial fragmentation, ecological disconnection, and inefficiencies in intermodal transfers caused by large-scale railway infrastructure. Using GIS-based analytical tools, the research examines how WKS was planned and built as a multidimensional hub. The analysis focuses on three core planning areas: transportation network integration, environmental impact assessment, and urban development visualization. City-Hub theory informs strategies including multimodal transfer systems, pedestrian networks, ventilation corridors, and green axes, all aimed at enhancing infrastructure connectivity and restoring ecological flow. Enter-Hub theory supports mixed-use zoning, the alignment of visual corridors in public spaces, and step-down skyline regulations to shape urban form and guide development. Empirical findings show that WKS functions not only as a transportation hub but also as a multilayered spatial platform that supports diverse urban functions. The case of WKS provides a reference model for GIS-based hub development strategies in future high-speed rail-oriented urban redevelopment projects.
