- Ấn phẩmTracking the construction land expansion and its dynamics of Ho Chi Minh City Metropolitan Area in Vietnam(2025) Liang, Yutian; [et al.]International industrial transfer has driven rapid construction land expansion in emerging metropolitan areas, posing challenges for sustainable land management. However, existing research has largely overlooked the spatiotemporal patterns and driving mechanisms of this expansion, particularly in Southeast Asian metropolitan regions. To address this gap, we focused on the Ho Chi Minh City metropolitan area, utilizing construction land data from GLC_FCS30D to analyze the dynamics of construction land expansion during this period. Findings indicated that: (1) Continuous expansion of construction land, with the expansion rate during 2010–2020 being five times that of 2000–2010; (2) The spatial pattern evolved from initial infilling development in urban cores to subsequent leapfrogging and edge expansion toward peripheral counties and transportation corridors; (3) The expansion of construction land occurred alongside substantial losses of wetland and cultivated land. Between 2000 and 2020, the conversion of cultivated land to construction land increased significantly, particularly during 2010–2020 when cultivated land conversion accounted for 93.76% of newly developed construction land. Wetland conversion also showed notable growth during this period, comprising 3.86% of total newly added construction land; (4) Foreign direct investment (FDI) served as the primary catalyst, while industrial park development and transport infrastructure projects functioned as secondary accelerants. This study constructed a framework to systematically analyze the global and local driving mechanisms of metropolitan land expansion. The findings deepen the understanding of land-use transitions in emerging countries and provide both theoretical support and policy references for sustainable land management.
- Ấn phẩmHorn use patterns and acoustic characteristics in congested urban traffic: A case study of Ho Chi Minh City(2025) Nguyen, Thu Lan; Nishimura, Yuya; Nishimura, SoheiMotorcycle horns are a dominant source of urban noise in many Southeast Asian cities, driven by high two-wheeler density and limited public transport infrastructure. Although automobiles have been in use for over a century, regulations governing horn design and volume control remain inadequate. This study investigates horn use behavior in Vietnamese urban traffic, identifying distinct acoustic patterns categorized as “attention” and “warning” signals. Measurements conducted in an anechoic chamber reveal that these patterns can increase sound pressure levels by up to 17 dB compared to standard horn use, with notable differences in frequency components. These levels often exceed the daytime noise thresholds recommended by the World Health Organization (WHO), indicating potential risks for adverse health outcomes, such as elevated stress, hearing damage, sleep disturbance, and cardiovascular effects. The findings are contextualized within broader efforts to manage traffic noise in rapidly developing urban areas. Drawing parallels with studies on aircraft noise exposure in Japan, this study suggests that long-term exposure, rather than peak noise levels alone, plays a critical role in shaping community sensitivity. The study results support the need for updated noise regulations that address both the acoustic and perceptual dimensions of road traffic noise.
- Ấn phẩmSpatial dynamics and drivers of urban growth in Thua Thien Hue Province, Vietnam: Insights for urban sustainability in the global South(2025) Obaitor, Olabisi S.; [et al.]Investigating the historical patterns of urban growth and their drivers is crucial to informing sustainable urban planning policies, especially in cities of the Global South. In Vietnam, most studies focus primarily on city extents, offering little insight into urban growth across various provinces. This study, therefore, combined categorical land use and land cover change detection, Random Forest classification and expert interviews to quantify the urban growth between 2000 and 2020, assess urban encroachment upon other land uses, and identify key drivers shaping this growth in Thua Thien Hue province. Findings show that the urban land areas were 27.94 km2 , 82.97 km2 , and 209.80 km2 in 2000, 2010, and 2020, respectively. Urban encroachment upon other land use types, especially cropland, barren land, rice paddies, shrubs, and forests, was observed in these periods. Additionally, accessibility to built-up areas, DEM, proximity to rice paddies, slope, proximity to street roads, accessibility to social areas, and proximity to cropland are the major spatial drivers of urban growth in the province. The study concludes that rapid urban expansion is evident in the province at the expense of other land use types, especially agricultural land use types, which may impact food security and livelihoods in the province.
- Ấn phẩmA transit-oriented development approach using the New South Wales places and movements framework for sustainable transport planning in Vietnam: A case study of an intersection in Ho Chi Minh City(ELSEVIER B.V, 2025) Tran, Thi Truc Lieu; [et al.]The rapid urbanization of cities with high population density has led to an increase in traffic demand in urban areas. Integrating land use planning with traffic planning can help limit congestion and avoid negative effects on urban development. Transit Oriented Development (TOD) is a planning strategy that combines land use and transportation planning to promote economic, environmental, and social sustainability. This approach is applicable in Ho Chi Minh City. Australia has successfully implemented a TOD approach based on the New South Wales Movement & Places Framework, which creates and maintains a safe and accessible environment for traffic vehicles, including pedestrians and cyclists. To evaluate the applicability of this approach to the Vietnamese situation, this study will clarify differences in road function classification between the Vietnam Standard (TCVNs) and the standard of New South Wales (AUsroads). The study will also explore the new points in the New South Wales standard on designing pedestrian and bicycle lanes compared to Vietnam’s standard. Finally, the New South Wales Movement and Places Framework will be applied to an intersection area in Ho Chi Minh City to create a safe and convenient environment for traffic vehicles, including pedestrians and cyclists.
- Ấn phẩmQuản lý đô thị trong bảo tồn và quản lý vườn hoa/ sân chơi khu dân cư trong các quận nội đô Hà Nội.(2015-03) Hiền, Nguyễn Thị; Ánh, Trần Huy; Hải, Đinh Đăng; Hà, Trần Thị Kiều Thanh; Dung, Trần Thị MỹViệt Nam đang trải qua quá trình đô thị hóa nhanh chóng cần đảm bảo sự bền vững. Thành phố Hà Nội đã được mở rộng lãnh thổ hơn khoảng ba lần so với trước kia, đòi hỏi phải sử dụng đất hiệu quả nhằm nâng cao chất lượng cuộc sống cho người dân, bao gồm cả những người sống trong các quận nội đô lịch sử, nơi có mật độ dân số và mật độ xây dựng cao. Vườn hoa/sân chơi khu dân cư là môi trường vật thể,và cũng là không gian xã hội, nơi mọi người đến thư giãn, tập thể dục và tương tác với nhau. Nằm không xa các nhà ở, chúng có lợi thế trong việc thu hút người dân đến thường xuyên hơn so với các công viên lớn hơn, nhưng ở xa hơn. Nghiên cứu này có mục đích cung cấp một phân tích hiện trạng về việc bằng cách nào và tại sao không gian công cộng đã bị mất đi hoặc xuống cấp; và xây dựng một chiến lược thực tế nhằm tăng số lượng và chất lượng của chúng tại các quận nội đô của Hà Nội.
- Ấn phẩmA geographical simulation of impacts of Vientiane-Hanoi expressway(2019) Keola, Souknilanh; Kumagai, SatoruIn this paper, we estimated the economic impacts of the proposed and some alternative routes of Vientiane-Hanoi Expressway (VHE), using a computational general equilibrium model based on spatial economics. The estimation results show that overall international positive impact depends more on whether it forms a cross-border expressway connection between the capitals of Vietnam and Thailand. The proximity of the expressway to Laos’s capital is nevertheless critical to economic benefits expected within Laos.
