{"title":"Spatial Structure of Places in Singapore from a Complexity Perspective of the Public Transport Network","authors":"H. Huynh","doi":"10.1142/s2972426023400032","DOIUrl":"https://doi.org/10.1142/s2972426023400032","url":null,"abstract":"As cities become increasingly developed, inclusive and equal provision of public services and affordable housing is essential in achieving sustainable growth and development. In Singapore, with much of the population living in public housing and taking public transport, there is a great need to understand their landscape across the country. In this study, using tools from Complexity Science, we elucidated the spatial organization of places in Singapore through public bus transport connectivity, and investigated the association between such pattern to the distribution of the population age groups and property price. From the spatial network of the public transport services, we probed the places’ scale using the continuum percolation approach to uncover their spatial pattern. After that, we employed an information-theoretic measure of complexity to quantify the spatial organization of the system. The results show that there is a critical distance embedded within the public transport system at which the structure of the places in Singapore emerges. In many areas, the connectivity between places map well, and are greatest within the official planning boundary, demonstrating the influence of upstream spatial planning in determining bus networks. Yet in mature towns (particularly those in the central region), bus connectivity spans beyond planning boundaries, suggesting a more organic pattern on the ground in places with a longer history of development. The complexity of the bus network maps remarkably well to residential areas, and was associated with the distribution of resident age groups, and to property prices. In particular, the well-connected areas in and around the central region of Singapore are associated with higher property price and an older population. In contrast, the peripheral less-connected areas tend to see a lower property price and a younger population. The findings can contribute to understanding the existing pattern of physical and social form within an urban system, highlighting the role of complexity science methods in uncovering ‘emergent’ patterns in bus transport networks, beyond initial spatial plans, as areas mature over time. It can also guide future planning by highlighting the areas where more attention is needed to enhance island wide public bus connectivity, and by doing so, enable the public transport system to contribute to reducing potential socio-economic polarization within the system.","PeriodicalId":243951,"journal":{"name":"International Journal on Smart and Sustainable Cities","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-08-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117197591","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These nodal developments leverage their urban context and programmatic offerings in a bid to generate a sustainable hub ecology for the city. A manifestation of the whole-of-government, and now whole-of-society approach, these large-scale communal architecture plays a significant role in rejuvenating the heartlands, advocating citizen engagement and advancing civil society. The vision behind this emergent typology is in the creation of synergistic and generative environments. This paper seeks to investigate the potential of this shared urban model of integrated communal architecture as testbed for better-than-sustainable concepts, to advance policy agendas and support wider collaboration to establish and achieve district-based targets in regenerative outcomes. Using Our Tampines Hub and Bukit Canberra as case studies, the paper looks at the complexities of synergistic operations, and analyses specific design strategies and the participatory approach to support an urban-social-natural regeneration framework. It examines not only economic value in land and space optimization, but new synergies produced for circular mind-shift, closed-loop environmental outcomes and social impetus.","PeriodicalId":243951,"journal":{"name":"International Journal on Smart and Sustainable Cities","volume":"104 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-08-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114185511","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Herthogs, B. Tunçer","doi":"10.1142/s2972426023400020","DOIUrl":"https://doi.org/10.1142/s2972426023400020","url":null,"abstract":"Planning administrations are concerned with the diffusion of art. The concept of the Creative City has encouraged planners to develop cultural policies to support creative economies, city branding, urban identity and urban quality. With the introduction of social media, the production and consumption of art is changing significantly. It has resulted in the emergence of hybrid art spaces: social spaces existing both in physical space and on social media. This implies that the integration of social media data in cultural planning is not just beneficial, but necessary. However, existing cultural planning approaches hardly consider this shifting paradigm. Therefore, this paper introduces a methodology to analyze, map and evaluate art venues and the online communication they generate using social media data. We developed this methodology for Singapore. We gathered geo-located Twitter data and extracted posts relating to art (Social Media Art Classifier). We applied topic and sentiment analysis to art tweets, and introduced social media-based planning indicators. We also developed a machine learning model to determine the relationship between 11 art venue features and the level of their social media production. This methodology successfully demonstrates the use of social media data to support cultural planning in cities. While the work presented in this paper focuses on Singapore, and is limited to a two-year data period, our methodology could easily be adapted for other locales, and to include continuous assessment. As a next step, we will demonstrate and discuss our methodology with cultural planning professionals, in order to improve our methods and indicators, and explore some of the applications suggested in this paper.","PeriodicalId":243951,"journal":{"name":"International Journal on Smart and Sustainable Cities","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-07-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129869497","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This research introduces a Network science-based spatial analysis framework to evaluate the connectivity and relationships of vertically integrated urban open spaces. Kampung Admiralty (KA), a unique development integrating housing for the elderly with various facilities, serves as a case study. The methodology combines static spatial network measures and real-world movement data to predict movement flows, accessibility, and connectivity. Lift lobbies and elevated garden connectors emerged as critical paths, effectively distributing pedestrian flows. Landscape spaces played a key role in visual and physical connectivity, offering high recreational and social value. Strategic placement of “social attractors” improved space utilization. The study highlights the importance of spatial design parameters in user-space interactions and provides insights into socio-spatial networks at both ground and elevated levels. It identifies key connectors that facilitate effective planning and design of vertically integrated public space networks, promoting social and spatial effectiveness.","PeriodicalId":243951,"journal":{"name":"International Journal on Smart and Sustainable Cities","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-07-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130288731","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In Singapore’s post-Independence history, urban green spaces have evolved from leftover manicured grassy areas to biodiverse spaces with recreational areas and facilities. Singapore has recognized the need to provide varying access to the public to protect the more natural areas from too much public access. In urban green spaces, different areas have varying access depending on the scale and significance of the natural habitat. This paper uses Spatial Network Analysis — or the study of topological spatial relationships — to inform the planning and design of varying levels of access in urban green spaces in Singapore. It investigates the influence of spatial configuration of urban green spaces on pedestrian movement, by studying two types of urban green spaces in Singapore: one-north Park and Jurong Lakeside Garden. In both cases, the research utilizes weighted Spatial Network Analysis using sDNA, an analytical tool, to gain insights into the correlations between spatial connectivity and pedestrian movement distribution patterns. Empirical quantitative data are collected using infrared-sensor devices and manual pedestrian count and activity mapping. The methodology can provide the basis for the future planning and design of pedestrian infrastructure in urban green spaces in Singapore, and other high-density cities.","PeriodicalId":243951,"journal":{"name":"International Journal on Smart and Sustainable Cities","volume":"15 11","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132546570","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The new measures give a direct quantification of the tendency of subsectors to spatially agglomerate, the likelihood of cross-subsector spatial co-agglomeration, and the potential of leading and following behaviors between firms. Unlike the conventional measures which deduce possible agglomeration through deviations from the baseline distribution or distance density, our measures study agglomeration in terms of clustering and co-location behaviors to provide a clear physical picture on spatial agglomeration. With each measure quantifying one of the three different ways in which firms agglomerate spatially, their collective use provides a combined perspective on the agglomeration behavior and location choice of firms that is not available from the conventional measures. We employ this joint application of measures to show that Singapore maritime firms have a propensity to distribute themselves spatially in a manner that allows them to reap the benefits of localization externalities from the agglomeration economy.","PeriodicalId":243951,"journal":{"name":"International Journal on Smart and Sustainable Cities","volume":"102 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-06-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121056664","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
