Abstract
In this research, we traced the process of urbanization of a small agricultural village in Korea through the massive construction of housing estates and the modern street network in the late 20th century. Whereas the existing literature tends to adopt a data-driven macroscopic approach to analyze periurban transformation, we concentrated on the morphological transition of old rural roads in a small village to provide a microscopic interpretation of how they are obliterated, fragmented, or preserved in relation to land types and the acquisition process. Through a careful investigation of various maps and archives, we found that the woodland was the main target for development. In contrast, clustered residential plots were the most enduring feature that resisted change, entailing that their internal route remained intact. To determine the potential benefit of an irregular old route within the modern block, network analysis was executed to measure its performance. The route was shown to provide efficient movement in the current system, especially within the scale of the old village. The preservation of old spatial legacy, therefore, helps assign historical, social, and practical meaning to the design a sustainable modern city.
Highlights
Urbanization implies both growth and condensing of the built environment
Using remote sensing and population information for the Ho Chi Minh City metropolitan area in Vietnam, this study indicated that 66% of urban expansion and 50% of population growth occurred in periurban communities between 1990 and 2012
Comparing the average sizes of registered land areas, we found that woodland was the biggest, farmland was in the mid-range, and residential land was the smallest
Summary
Urbanization implies both growth and condensing of the built environment. When it is gradual, the intervention of new buildings and roads often mingles with the existing landscape. The intervention of new buildings and roads often mingles with the existing landscape When it is radical, the old spatial memory can be obliterated. Major arterial roads re-frame the boundary of the area and externally impose a new spatial order. The most common element of these is old roads in major cities. It is these fragments from the past that this research focuses on as a clue to trace the typical process of urbanization in Korea in the late 20th century. What are the driving forces behind the persistence of old roads in the urban setting? what influences their morphological transition to fragmentation or demise?
