Toward Inclusive Cities: Mapping Activity-Space Segregation between Residents and Tourists in Jeju, South Korea

Abstract

Enhancing urban inclusiveness has received growing attention from scholars, yet empirical research on measuring urban inclusiveness remains scarce. Aiming to bridge this gap, this research proposes reduced socio-spatial segregation as a proxy for spatial urban inclusiveness, grounded in the principle that urban inclusiveness inherently counters urban segregation. Employing a multidimensional activity space-based segregation framework from sociology and geography, this study quantifies resident-tourist segregation through mobility patterns in tourism-reliant cities, using Jeju, South Korea as a case study. Specifically, it analyzes over 12 million car navigation data points with Point of Interest (POI) information, reflecting travel mobility of stakeholders at the urban destinations. By measuring multidimensional segregation within shared activity spaces at global and local scales, this research uncovers: (1) spatial disparities in socio-spatial segregation across various activity spaces, and (2) moderate island-wide diversity masking extreme local segregation. The findings provide urban policymakers and planners with actionable insights to evaluate, monitor and address potential segregated hotspots through targeted policy interventions, ultimately fostering more inclusive urban environments.
