The main objective of this study is to demonstrate the potential of hyperspectral data to identify roof materials in cities. The case study area is located in a Mediterranean region north of Barcelona (Spain); diverse building typologies, building uses (residential, industrial, office, services and retail) and population densities constitute this study area. Two hyperspectral remote sensors (HRSs) were used to obtain hyperspectral images. Seven roof classes were identified using the k-means clustering algorithm. Most roofs were identified as metals (33 percent), followed by ceramic tiles (22 percent). The findings showed that 51 percent of roofs could be suitable for food, water, or energy production. Nevertheless, for a more reliable assessment of this potential, more criteria are needed.","PeriodicalId":47593,"journal":{"name":"Journal of Urban Technology","volume":"37 1","pages":"25 - 51"},"PeriodicalIF":4.8,"publicationDate":"2023-10-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139316437","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The model employs a fan-shaped sampling method to divide experimental areas, extracts the functional zone sequence from sea to land along each sample line to establish the sample data set and mines the optimal functional sequence in each experimental area through association rules. Qingdao Port, Johor Port, and Manila Port are selected as experimental areas to verify the model, and the random forest (RF) model is adopted to identify the urban functional zones during different periods. The results indicate that the development of ports has a profound impact on the spatial configuration and structure of functional zones from sea to land. This method is conducive to solving the technical problems associated with the spatial and interactive development of port cities and provides a model reference for studies of the spatial correlation in other regions. Only by overall control and planning, overall coordination of the distribution of various functional areas, and reasonable spatial layout will the development of ports and cities be sustainable.","PeriodicalId":47593,"journal":{"name":"Journal of Urban Technology","volume":"4 1","pages":"101 - 120"},"PeriodicalIF":4.8,"publicationDate":"2023-10-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139315849","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study examines the spatial pattern of emerging industries under the influence of new technologies within the context of China’s “Internet Plus” initiative. It constructs a theoretical framework from an evolutionary economic geography (EEG) perspective and highlights the interdependence between the Internet Plus economy and urban systems. The analysis finds that the development of Internet Plus in cities intensifies the spatial agglomeration of new economic resources, and results in industrial transformation led by only a few large cities and spatial polarization within the urban system. However, advances in Internet technologies also provide a window of opportunity for smaller cities, and local industrial bases and relevant specializations play a crucial role in this process.KEYWORDS: Internet Pluspath-dependencewindow of opportunityindustrial transformationurban system AcknowledgmentsThe research was supported by National Social Science Foundation of China (19AZD007) and Innovation Program of Shanghai Municipal Education Commission.Disclosure statementNo potential conflict of interest was reported by the author(s).Notes1 According to the National New Urbanization Plan (2014–20), China has 17 megacities whose population is more than 5 million.

Therefore, this article aims to evaluate and rank existing MaaS services to support the development of future MaaS applications by highlighting the most relevant features. Thus, a framework of the technical aspects is created, where the aspects are categorized into routing, booking, payment, ticketing, and supplementary services. Based on the defined aspects and their sub-aspects, an evaluation of selected applications is performed in three stages by applying the Analytical Hierarchy Process (AHP) method. In the first stage, the assessment of the examined MaaS services is carried out by using a multi-criteria analysis (i.e., scoring). In the second stage, the relative importance of the aspects is weighted (i.e., weighting). The third stage is based on the ranking of MaaS services by taking the weights of the aspects into account. According to the achieved scores, the analyzed MaaS services earn only 44 percent of their potential maximum value, and the payment is the most important among the technical aspects. The applied method reveals quantified results, which provides valuable guidelines for future implementations, especially for application developers.KEYWORDS: Mobility as a Service (MaaS)MaaS featuresAnalytical Hierarchy Process (AHP)application rankingmulti-criteria analysis AcknowledgmentProject no.

This viewpoint argues that a smart governance approach should be applied to remodel the uniform, often technocratic and corporate-led way of coping with COVID-19 in the smart city context. There is a need to develop more technology-enabled collaborative actions across sectors and among various actors to recover better from the pandemic. A far-sighted view is also needed to build citizen-centric open governance capacities—the emergent character of mass participation in cities—for readiness, responsiveness, and long-term resilience.

Who decides what makes a city smart and who is that smart city for are crucial questions for the urbanist literature to systematically address. Despite the concept’s recent popularity, “smart city” is a contested term and remains a chaotic dimension of urban theory. Theorizing the smart city in a US context must address a particular mix of built forms, public policies, and social conditions—all of which shape how transportation and other systems help constitute the city. To deepen understanding of the smart city concept in both theory and practice, this research explores the framing, construction, and contestation of the smart city concept through the U.S. Department of Transportation’s (USDOT’s) Smart City Challenge (SCC), launched in 2015 as a competitive grant program with the intent to provide a spark for incentivizing the development of smart infrastructure in mid-sized US cities. We compare the action plans of the seven finalist cities selected to create plans to implement their visions, including Columbus, Ohio, the eventual winner. We employ interpretivist content and discourse analysis of the applications and award decision, as well as of early implementation in Columbus, to explore shared meanings of recurring themes and key concepts, building a grounded theory of the smart city in the US context. The findings of the comparative analysis reveal further insights into prevailing challenges in smart city deployment, particularly for areas lacking inherent technology platforms.KEYWORDS: smart cityvision elements (VEs)U.S. Department of Transportation (USDOT)Smart City Challenge (SCC)Columbus Disclosure StatementNo potential conflict of interest was reported by the author(s).Additional informationNotes on contributorsJae Teuk ChinJae Teuk Chin is an associate professor in the International School of Urban Sciences at the University of Seoul.Andrew GuthrieAndrew Guthrie is an assistant professor in the Department of City and Regional Planning at the University of Memphis.","PeriodicalId":47593,"journal":{"name":"Journal of Urban Technology","volume":"95 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-08-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135841311","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
