Evaluating the accessibility of green networks: a case study on new cities in Seoul metropolitan area

Abstract

Demand for urban green networks has increased and the accessibility have become major concerns, but related discussions have so far been restricted only to green spaces. Through a case study on second and third phase new cities in Seoul metropolitan area, this study suggests new indicators to evaluate the synergy between road and green networks in urban areas. Applying the suggested method on the new cities of Dongtan, Wirye, Wangsuk and Gyosan, this study demonstrates how the indicators explain the spatial structure of the green networks and verifies the structural characteristics of each new city. One of the main conclusions are that third phase new cities’ green networks have higher integration and lower control. Implications for the difference between cities and phases are further discussed.
