Knowing where and when future demands for travel are expected allows operators to adjust timetables quickly, which helps improve service quality and reliability and attract more passengers to public transport. This study addresses this need by developing AI-based deep learning models for prediction of bus passenger demands based on actual patronage data obtained from the smart-card ticketing system in Melbourne. The models, which consider the temporal characteristics of travel demand for some of the heaviest bus routes in Melbourne, were developed using real-world data from 18 bus routes and 1,781 bus stops. LSTM and BiLSTM deep learning models were evaluated and compared with five conventional deep learning models using the same data set. A desktop comparison was also undertaken against a number of established demand forecasting models that have been reported in the literature over the past decade. The comparative evaluation results showed that BiLSTM models outperformed other models tested and was able to predict passenger demands with over 90% accuracy.</p></div>","PeriodicalId":45131,"journal":{"name":"Journal of Urban Management","volume":"11 3","pages":"Pages 365-380"},"PeriodicalIF":6.1,"publicationDate":"2022-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2226585622000280/pdfft?md5=915133685c1ad571ec129eaae38ae321&pid=1-s2.0-S2226585622000280-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48936299","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"社会学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This process, however, is quietly creating urban migration patterns that are altering the demographic profile of cities with cumulative change that we cannot fully estimate at this stage. There is growing need for a granular analysis at the parcel level to refocus the spotlight on this quiet displacement force. To start filling this lacuna, the article links privatization processes to gentrification and displacement. Through a case study of the privatization of Mitchell Lama buildings on Roosevelt Island, NYC, and the demographic changes it has engendered, this study points to a more significant trend of privatization of housing projects in American cities and worldwide. Its main argument is that, despite their quiet nature, which differs fundamentally from the Urban Renewal projects of the 1960s, the cumulative change they produce may be similar. On this basis, <strong>this study's main contribution is an in-depth, small-scale analysis aimed at deciphering the mechanisms, motivations, and decision-making processes of households experiencing ongoing privatization</strong>. Through a combination of ethnographic fieldwork, urban historical research, and statistical analysis, the study identifies three urban trends: 1. Privatization may lead to exclusionary displacement through increases in rent and cost of living; 2. Privatization may lead to social displacement pressures such as a sense of loss of place, loss of friends and community, and resentment among long-term residents; and 3. If the right policies are developed, privatization can present an opportunity for upward social mobility.</p></div>","PeriodicalId":45131,"journal":{"name":"Journal of Urban Management","volume":"11 3","pages":"Pages 285-297"},"PeriodicalIF":6.1,"publicationDate":"2022-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2226585622000048/pdfft?md5=6147b64bb52a4119614bae553a77aeaa&pid=1-s2.0-S2226585622000048-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48768910","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"社会学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The ratio of ‘blue’ water spread areas to ‘built-up’ ratio around the lakes, defined as the ‘Blue to Built-up ratio’ (BBA), 3. the percentage of impervious surface area (ISA) and 4. the pace of urbanisation in the dynamic zones (DZ) of urban lake environments. These new metrics were evaluated using landcover areas mapped from satellite imageries. Visual interpretation-based method was adopted to delineate the green, blue and built-up areas from Google Earth, which is suitable for wide range of users. The use of these metrics has been illustrated using available datasets for four representative lakes in Bengaluru city, India: Sankey tank, Ulsoor lake, Nagavarakere and Puttenahallikere. Significant spatio-temporal variations in the ratios of GBA and BBA as well as %ISA were observed and satisfactorily reflected the ecological status of these lakes in concurrence with earlier studies. Detailed analyses constrained a permissible rate of annual increase in the built-up area within the DZs to ∼ 3% for sustainable development of the lakes.

One of the most important reasons is the local governments’ strategy choice in land use. In this research, a governance structure from the view of the tax-sharing system and the performance appraisal system is constructed to explain the causes of extensive land use using game theory analysis. The key finding is that the governance structure in industrial land use is an organizational structure composed of the central government, local government and the market, and these three participants hold inter-conditioned relationships so as to form a closed loop. However, a bottom-up relationship chain from the market is absent in this structure, which makes it difficult to rely on local governments to implement intensive use of industrial land by themselves. Game equilibrium analysis shows that if a performance penalty coefficient is considered to refine the existing performance appraisal system to help produce a market feedback, the possibility of local governments adopting extensive land use strategies will be reduced.</p></div>","PeriodicalId":45131,"journal":{"name":"Journal of Urban Management","volume":"11 3","pages":"Pages 298-309"},"PeriodicalIF":6.1,"publicationDate":"2022-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S222658562200005X/pdfft?md5=3b4ee0fb679c225ad4a0f0c00876f1b8&pid=1-s2.0-S222658562200005X-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42574669","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"社会学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Modern urban areas are in a permanent state of flux because of changing preferences, willingness to pay, location choices, and physical development. In this constantly changing context, what is the most appropriate delimitation of a “neighborhood”, defined as a small and relatively homogeneous area in a certain (and temporary) urban configuration? This paper contributes to the growing literature on the use of data analytic tools in urban studies and neighborhood delimitation in housing sub-markets, exploiting big data on real-estate transactions in England and Wales during a long period of time. The results shed light on the importance of organic urban features and the drawbacks of rigid geometric definitions. They also highlight the importance of the usage of deep Machine Learning (ML) tools such as Artificial Neural Network (ANN), alongside with traditional methods. The paper's contribution to urban governance is the suggestion of a smart and dynamic system aimed at defining the most appropriate areas for urban management given a specific period and situation. The suggested framework can be implemented periodically, helping to define homogeneous spatial units (neighborhoods) with large variances among them, allowing for designing urban policies tailored to each one of them.</p></div>","PeriodicalId":45131,"journal":{"name":"Journal of Urban Management","volume":"11 2","pages":"Pages 178-187"},"PeriodicalIF":6.1,"publicationDate":"2022-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2226585622000310/pdfft?md5=67563a32bd6988f7cae3c1cd18d8fd23&pid=1-s2.0-S2226585622000310-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44440732","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"社会学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A case study of Beijing is further conducted, with different methodologies leading to distinguished results, which proves the necessity of employing various methods to enhance the validity of experience mining for urban transitions.
