Public transport plays a critical role in the sustainability of urban settings. The mass mobility and quality of urban lives can be improved by establishing public transport networks that are accessible to pedestrians within a reasonable walking distance. Accessibility to public transport is characterized by the ease with which inhabitants can reach means of transportation such as buses or metros. By measuring the degree of accessibility to public transport networks using a common data format, a
Since the initiation of Vietnam’s Doi Moi policy in 1986, the rate of urbanization has rapidly increased with a great influx of immigrants from rural areas. With such migration becoming a large acceleration factor for urban growth, the shortage of housing has become a critical problem in the cities. The Vietnamese government encouraged self-built housing and public–private partnerships to produce different types of housing stock. There are few available academic studies about housing choice in V
Since the Doi Moi policy of economic reform in 1986, Vietnam has experienced economic development and housing market growth with increasing foreign direct investment. While high-end apartment development has dominated since the emergence of the privatized housing market, more recent focus is on the affordable apartment segment with the remarkable surge of middle-income households in Ho Chi Minh City (HCMC). While most previous studies have analyzed housing price determinants based on locational
Points of interest (POIs)—areas with a concentration of places that attract people—are important urban planning and tourism policy targets. This study aims to determine the points of interest of urban residents by analyzing big data from search engines to reveal the physical characteristics of POIs. To achieve this, POI data were collected in three city centers in Seoul using a South Korean dominant portal site that includes a search engine. The most popular POIs were determined by using GIS sea
In recent years, many cities in developed countries have struggled with housing vacancy. Empty homes are accompanied by social problems such as vandalism, arson, unsanitary environments, and collapse risk. Vacant houses also have negative effects on the value of nearby properties and their local communities. Accordingly, there have been various policy responses to tackle this problem. In spite of these efforts, however, the number of vacant houses continues to increase alongside a population dec
Urban megaprojects change the city in various ways over a long period of time. These changes may be very clear and calculable, but it is the changes that follow which are unpredictable and extensive. Especially in fast-changing cities like Seoul, Korea, projects like the Cheonggyecheon Restoration have massive effects on the surrounding environment. The purpose of this study is to analyze the spatial changes in the downtown area after the Cheonggycheon Restoration Project (2005). The economic; s
Abstract City tourism is one of the fastest growing industries worldwide. City tourism based on the attractiveness of the city is an important policy objective to secure competitiveness and sustainability of the city. However, as a city attracts more tourists, this uniqueness tends to decrease with the introduction of global corporate franchises as well as the construction of standardised buildings. Policymakers focus more on building hotels and shopping centres than on enhancing the cityscape.
Innovation City projects, aimed at balanced national development in South Korea, have relocated public institutions from the Seoul metropolitan area to provinces, decentralizing population and economic functions, over the past decade. This study measured changes in regional centrality (the central and local location or hierarchy of objects in a network) at the 14 cities where Innovation City projects were constructed. Commuter Origin-Destination data were analyzed using Rstudio. In the case of c
Germany looks back at a rapidly changing developmental period in which the western part of the country experienced economic prosperity during the 1950s, whereas the eastern part experienced a different start. This situation persisted till the German reunification in 1989. After reunification, Germany's policies were similar to those of the post-WWII period—it focused on the most important needs such as social injustice in cities and quarters and too much (eastern federal states) or too little (w
The rates of depression among young adults have been increasing in high-income countries and have emerged as a social problem in South Koreans aged 19-34. However, the literature is unclear on whether the neighborhood environment that young adults live in affects the onset and severity of their depressive symptoms. This study analyzed data from the 2019 Korean Community Health Survey (KCHS) using the Tobit model to identify the effect of the neighborhood environment on young adults' depressive m
This paper explores the functional pragmatism embedded in the transformation of feudal Seoul′s urban structure. Using historic maps drawn between 1751 and 1914 and an analytical method of space syntax, the paper documents changes in the distribution of major administrative buildings and streets in Seoul (″Hanseongbu″) during the Joseon Dynasty. The results indicate that administrative buildings such as palaces, royal villas, economic authority buildings, and military headquarters were relocated
Pedestrian-friendly cities are gaining traction worldwide. This study focused on sidewalk width and green space designs that comprise the walking environment. This study examined uniform planting patterns made without considering the width of the sidewalk and derived an appropriate green area pattern created according to the width of the sidewalk. We conducted a survey using virtual reality, satisfaction and preference review, and multilinear regression analysis. The results showed that ensuring
