A Study on the Spatial Structure of the Bu-Ul-Gyeong Megacity Using the City Network Paradigm

Developing bidirectional urban networks within areas in megacities is an essential spatial strategy across regions today. In 2018, Korea began its Bu-Ul-Gyeong (BUG) megacity project. Today, working to improve functional polycentric the BUG megacity. To uncover insights useful for this project, study sought examine network patterns (e.g., asymmetries and imbalances sizes directions of their weighted flows) identify primary secondary centers using mobile flow data from 2019 2020. Specifically, a three-step social analysis was conducted different geographical scales; namely: (1) megacity, (2) South Gyeongsang Province (SGP), (3) every community SGP. Eigenvector centrality betweenness revealed two (Changwon Jinju) four (Haman, Sacheon, Tongyeong, Geochang). Unidirectional hierarchical connections were evident between centers. response these findings, paper proposes some beneficial strategies region’s public transportation prevent small- medium-sized cities being marginalized enhance horizontal connectivity megacities.
