Precise distinction of mixed functions on urban land is essential for urban studies and planning, while existing methods are limited by high sampling bias, low observation frequency, and lack of semantic information in common data sources. In this paper, we introduce a new proxy for human behavior, the telecom traffic data as a remedy to the above limitations, and present an analytical framework which utilizes anonymized and aggregated telecom traffic data to infer mixed urban functions at spatiotemporal granularities as fine as buildings and hours. A time-series decomposition method is designed to map the mixture of urban functions, which is further refined by a hierarchical agglomerative clustering method taking urban textures as an additional source of information. In a case study in Shenzhen, China, we find the function of urban buildings can be decomposed into the mixture of three basic functions, namely dwelling, work, and recreation. We further find that the introduction of urban texture information helps identify particular forms of functional combination, which indicate special-function buildings such as urban villages and roadside shops. This study implies ways to improve urban management through methodological contributions in mixed urban function identification alongside the introduction of the telecom traffic, a kind of “high-frequency” urban data, and also helps inspire a rethinking of the form/function dichotomy in the era of “High-frequent” cities.
精确区分城市用地上的混合功能对于城市研究和规划至关重要,而现有方法受限于高抽样偏差、低观测频率以及普通数据源语义信息的缺乏。在本文中,我们引入了一种新的人类行为替代物--电信流量数据来弥补上述局限,并提出了一个分析框架,利用匿名和聚合的电信流量数据来推断细至建筑物和小时的时空粒度的城市混合功能。我们设计了一种时间序列分解方法来绘制城市功能混合图,并将城市纹理作为额外的信息来源,通过分层聚类方法对其进行进一步细化。在对中国深圳的案例研究中,我们发现城市建筑的功能可分解为居住、工作和娱乐三种基本功能的混合。我们还进一步发现,城市肌理信息的引入有助于识别特殊的功能组合形式,这表明城中村和路边商店等特殊功能的建筑。这项研究通过引入电信交通这种 "高频 "城市数据,在城市混合功能识别方面的方法论贡献,为改善城市管理提供了途径,也有助于启发人们在 "高频 "城市时代重新思考形式/功能二分法。

This research proposes a design system that combines a case-based learning algorithm with a rule-based optimization algorithm to automatically generate and revise urban form prototypes based on historical cases and user requirements. The system aims to address the challenges of existing generative methods for urban forms, such as the lack of flexibility and organicity of rule-based methods and the insufficient manipulability and interpretability of the newest GAN-integrated case-based methods. It can help designers generate multiple solutions with specific indicators in the conceptual stage and has the potential to facilitate citizen participation in urban planning and design. This research demonstrates the feasibility and effectiveness of the system through a case study in Shenzhen. The research further extends the discussion about the application of the proposed system and the alternative evolution approach for the next generation of automatic design methods.

This study analyzed physical distancing in people’s daily lives and its association with travel behavior and the use of transportation modes before the COVID-19 outbreak. We used data from photographic images acquired automatically by lifelogging devices every 5 seconds, on average, from 170 participants of a 2-day wearable camera study, in order to identify their physical distancing status throughout the day. Using deep-learning computer vision algorithms, we developed three measures which provided a near-continuous quantification of the proportion of time spent without anyone else within a distance of approximately 13 meters, as well as the proportion of time spent without others within approximately 2 meters. These measures are then used as outcomes in beta regression and multinomial logit models to explore the association between the participant’s physical distancing and travel behavior and transportation choices. The multidisciplinary research approach to understand these associations accounted for a number of social, economic, and cultural factors that potentially influenced their physical isolation levels. We found that participants spend a significant amount of time physically separated from others, without anyone else within 2 meters. The use of public transportation, automobiles, active travel, and an increase in trip frequency, including trips to transportation facilities, reduced the extent of physical distancing, with public transportation having the most significant impact. Higher incomes, strong social networks, and a sense of belonging to the community reduced the tendency for physical distancing. In contrast, factors such as age, obesity, dog ownership, intensive use of the Internet, and being knowledgeable about climate change issues increased the likelihood of physical distancing. The paper addresses a crucial gap in our understanding of how these factors intersect to create the dynamics of physical distancing in non-emergency situations and highlights their planning and operational implications while showcasing the use of unique person-based physical distancing measures derived from autonomously collected image data.
本研究分析了新冠肺炎疫情爆发前人们日常生活中的身体距离及其与出行行为和交通方式使用的关系。在为期2天的可穿戴相机研究中,我们使用了170名参与者平均每5秒通过生活记录设备自动获取的摄影图像数据,以确定他们全天的物理距离状态。使用深度学习计算机视觉算法,我们开发了三种测量方法,这些方法提供了在大约13米的距离内无人陪伴的时间比例的近乎连续的量化,以及在大约2米的距离内无人陪伴的时间比例。然后将这些测量结果用作beta回归和多项逻辑模型的结果,以探索参与者的物理距离与旅行行为和交通选择之间的关联。了解这些关联的多学科研究方法考虑了可能影响其物理隔离水平的许多社会、经济和文化因素。我们发现,参与者花了相当多的时间与他人分开,两米内没有其他人。公共交通工具、汽车的使用、主动出行以及出行频率的增加(包括前往交通设施的出行)降低了物理距离的程度,其中公共交通的影响最为显著。较高的收入、强大的社会网络和对社区的归属感减少了身体距离的倾向。相比之下,年龄、肥胖、养狗、密集使用互联网以及对气候变化问题的了解等因素增加了保持身体距离的可能性。本文解决了我们对这些因素如何相互作用在非紧急情况下产生物理距离动态的理解中的一个关键空白,并强调了它们的规划和操作影响,同时展示了使用基于自主收集的图像数据的独特的基于人的物理距离措施。

Events are the driving force behind social media, whether we try to create them or keep up with them. A wide range of studies has focused on how content from social media can be used to detect, model and predict events and identify key topics of discussion. At the same time, very limited attention has been given so far to the quantitative study of the everyday, which has fascinated qualitative human geography research in the past few decades. That is partly due to the lack of a formal definition of what constitutes the everyday. In this paper, we aim to advance our understanding of the everyday, not by reducing it to any kind of definition but by bringing it into view through a quantitative analysis. We hypothesise that the by-products of current methods focused on event detection might be used to quantitatively explore everyday geographies as represented through Twitter data. We consider the use of both statistical approaches based on term frequency and state-of-the-art large language models, and we conduct a case study on content posted on Twitter and geolocated in the city of Leicester. Our paper makes two key advances for research concerned with the everyday and the analysis of geographic information. First, we illustrate how large language models combined with spatial analysis and visualisation can foster the study of everyday geographies, providing an insight into the still elusive concept of the everyday, representing what other approaches to the everyday have struggled to qualify. Secondly, we showcase the potential held by large language models and visual analytics in democratising sophisticated natural language processing and thus providing new tools for research in human geography.
事件是社交媒体背后的驱动力,无论我们是试图创造事件还是跟上事件的发展。广泛的研究集中在如何利用社交媒体的内容来检测、建模和预测事件,并确定讨论的关键话题。与此同时,对日常生活的定量研究迄今为止受到的关注非常有限,这在过去几十年里吸引了定性人文地理研究。这在一定程度上是由于缺乏对日常构成的正式定义。在本文中,我们的目标是推进我们对日常的理解,不是通过将其减少到任何一种定义,而是通过定量分析将其带入视野。我们假设,当前专注于事件检测的方法的副产品可能用于定量地探索通过Twitter数据表示的日常地理。我们考虑使用基于术语频率的统计方法和最先进的大型语言模型,并对Twitter上发布的内容和位于莱斯特市的内容进行了案例研究。本文在地理信息日常研究和地理信息分析两方面取得了重要进展。首先,我们说明了结合空间分析和可视化的大型语言模型如何促进日常地理的研究,提供了对仍然难以捉摸的日常概念的洞察,代表了其他日常方法难以达到的标准。其次,我们展示了大型语言模型和视觉分析在使复杂的自然语言处理民主化方面所具有的潜力,从而为人文地理学的研究提供了新的工具。

Mobile phones share location records, offering the opportunity to monitor and understand emerging population dynamics in urban centers. With the aim of supporting urban planning, this study introduces a scalable methodology grounded on extracting and organizing spatiotemporal statistics from decomposed population density data. The proposed methodology serves three major purposes: (i) assess the predictability of spatiotemporal citizen density patterns; (ii) detect emerging spatiotemporal trends in population density; and (iii) uncover multi-level seasonality patterns with guarantees of actionability. Additionally, it makes available an open-access tool for deploying the proposed methodology and analyzing mobile phone network data with easy-to-use spatiotemporal visualization and navigation facilities. The results obtained from real-world, large-scale mobile data in Lisbon, Portugal, demonstrate the effectiveness and validity of the proposed methodology in extracting actionable statistics in linear time to guide both tactic and strategic urban planning.

The 2022 United Nations Climate Change Conference (COP27) reaffirmed the most urgent need to build actions to accelerate the restoration of policies to arrest and reverse the loss of natural ecosystems by 2030 and move towards full ecosystem recovery by 2050. Land take is a significant source of emissions and contributes to global warming and biodiversity loss in natural ecosystems. Consequently, it is crucial to act on it by investigating the phenomenon quantitatively and formally, thus contributing to the goal of zero net land take. In recent years, land take worldwide has become massive, leading in some cases to forming compact, high-density urban settlements. In other cases, it has led to dispersed, low-density urban settlements. The basic assumption underlying this research is that a compact context is more sustainable (environmentally, economically, and socially) than a dispersed urban one. Consequently, this research aims to investigate the evolution of land take from the point of view of the pattern of urban settlements and their dispersion over the Italian territory. The spatial configuration of the Italian settlement pattern at the regional and provincial level was analyzed through a Spatio-temporal analysis of the global Moran index and other quantitative variables. The results provide, for each territory, a reading of the main expansion dynamics that occurred from the ‘50s to nowadays: compact city, urban sprawl, or urban sprinkling.
2022年联合国气候变化大会(COP27)重申,最迫切需要采取行动,加快恢复政策,到2030年遏制和扭转自然生态系统的丧失,到2050年实现生态系统的全面恢复。土地占用是一个重要的排放源,并导致全球变暖和自然生态系统中生物多样性的丧失。因此,通过定量和正式地调查这一现象来采取行动是至关重要的,从而有助于实现零净土地占用的目标。近年来,世界范围内的土地占用变得巨大,在某些情况下导致形成紧凑、高密度的城市住区。在其他情况下,它导致了分散的、低密度的城市定居点。本研究的基本假设是紧凑的环境比分散的城市环境更具可持续性(环境、经济和社会)。因此,本研究旨在从城市住区模式及其在意大利领土上的分散的角度来调查土地的演变。通过对全球Moran指数和其他定量变量的时空分析,分析了意大利人聚落在区域和省级层面的空间格局。结果为每个地区提供了从50年代到现在的主要扩张动态:紧凑城市,城市蔓延或城市零星分布。

Due to COVID-19, the urban lockdown has caused a significant impact on the mental health of residents. However, limited research investigates the role of neighborhood factors on residents’ mental health during and after the lockdown. This study examines Wuhan, the first city to experience the COVID-19 outbreak, employing multiple linear regression and XGBoost algorithms to analyze the emotional status and distribution of Wuhan residents. The goal of this study is to identify the moderating effect of the neighborhood environment scale on emotional positivity and the marginal effect of the neighborhood environment on residents’ emotions. The results of the study indicate that specific neighborhood environmental characteristics have varying effects on residents’ positive emotions, both before and after the COVID-19 lockdown. The green space ratio, attraction density, waterfront space density, and service facility density all positively affected mood within different distance ranges. Shopping facilities, on the other hand, had mainly positive effects during the open period, with negative effects during the closed period. Furthermore, this study determined scale thresholds where neighborhood environments had a positive effect on mood. For instance, attractions and waterfront areas improved the mood of residents in residential areas, up to at least 3 km away. Medical facilities had a positive effect on residents’ mood beyond 2.2 km. This study highlights crucial implications for planning and managing neighborhoods to promote resilience during future public health crises.
由于新冠肺炎疫情,城市封锁对居民的心理健康造成了重大影响。然而,有限的研究调查了邻里因素在封锁期间和之后对居民心理健康的影响。本研究以武汉为例,采用多元线性回归和XGBoost算法分析武汉居民的情绪状态和分布。本研究旨在探讨社区环境量表对居民情绪积极性的调节作用,以及社区环境对居民情绪的边际效应。研究结果表明,在新冠肺炎封锁前后,特定的社区环境特征对居民的积极情绪有不同的影响。绿地比例、景点密度、滨水空间密度、服务设施密度在不同距离范围内均对心情产生正向影响。另一方面,购物设施在开放期间的影响主要是积极的,而在关闭期间则是消极的。此外,本研究确定了社区环境对情绪有积极影响的尺度阈值。例如,景点和滨水区改善了至少3公里以外的居民区居民的情绪。医疗设施对2.2公里以外居民的情绪有积极影响。这项研究强调了在未来公共卫生危机中规划和管理社区以促进复原力的重要意义。

The green space ratio, attraction density, waterfront space density, and service facility density all positively affected mood within different distance ranges. Shopping facilities, on the other hand, had mainly positive effects during the open period, with negative effects during the closed period. Furthermore, this study determined scale thresholds where neighborhood environments had a positive effect on mood. For instance, attractions and waterfront areas improved the mood of residents in residential areas, up to at least 3 km away. Medical facilities had a positive effect on residents’ mood beyond 2.2 km. This study highlights crucial implications for planning and managing neighborhoods to promote resilience during future public health crises.","PeriodicalId":11863,"journal":{"name":"Environment and Planning B: Urban Analytics and City Science","volume":"61 14","pages":""},"PeriodicalIF":3.5,"publicationDate":"2023-12-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138604871","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}

Despite planning support systems (PSS) becoming increasingly useful for citizen participation processes, the effects of such systems’ material and spatial setup on citizen participation processes still need to be studied. PSS have long been equated to software- and data-based technologies, and only little attention has been put on place-bound PSS that prescribe onsite face-to-face collaboration. As closing the ‘implementation gap’ requires extensive conceptualisation, description, and critical analysis of different ideal types, workings, and use cases of PSS, this study researches this understudied place-bound type of PSS. More precisely, this study uses empirical material from Haifa’s 3 S Lab to contribute to closing the implementation gap by identifying place-bound PSS – an under-studied type of PSS – as useful for deliberative decision-making – an overlooked implementation context. This research advances the conceptualisation of PSS by discussing place-bound PSS and their hypothesised utility, practical setup, and empirically tested benefits for deliberative citizen participation. We find that the benefits of place-bound PSS for planning lie in deliberative affordances that ease the communication and comprehension deficiencies that often plague deliberative citizen participation processes. As place-bound PSS, the 3 S Lab provides an immersive shared space that improves communication, while its interactive visualisation techniques afford improved comprehension of complex urban issues.
尽管规划支持系统(PSS)对公民参与过程的作用越来越大,但此类系统的物质和空间设置对公民参与过程的影响仍有待研究。长期以来,规划支持系统一直等同于以软件和数据为基础的技术,人们很少关注那些需要现场面对面合作的、与地点相关的规划支持系统。要缩小 "实施差距",需要对 PSS 的不同理想类型、工作原理和使用案例进行广泛的概念化、描述和批判性分析,因此本研究对这一未被充分研究的地点绑定型 PSS 进行了研究。更确切地说,本研究利用海法 3 S 实验室的经验材料,通过确定场所约束型 PSS(一种研究不足的 PSS 类型)对审议决策(一种被忽视的实施环境)的有用性,为缩小实施差距做出贡献。本研究通过讨论与地点相关的个人和社会服务及其假设效用、实际设置以及经过实证检验的公民参与议事的益处,推进了个人和社会服务的概念化。我们发现,与地点相关的计划支助服务对规划的益处在于其审议能力,它能缓解经常困扰公民审议参与过程的沟通和理解缺陷。3 S 实验室作为与地点相关的 PSS,提供了一个身临其境的共享空间,改善了交流,而其交互式可视化技术则提高了对复杂城市问题的理解能力。

This study aimed to analyze the improvement in outdoor thermal environment by greening of persistently vacant housing and open areas in a densely built old downtown area of Busan Metropolitan City using ENVI-met. Simulation was performed for a summer day by constructing four scenarios for four areas considering the building density and slope direction. The results indicate that compared to the current scenario, the concrete scenario had the worst thermal environment, where the average temperature, mean radiant temperature (MRT), and physiological equivalent temperature (PET) increased by 0.04°C, 1.49°C, and 0.51°C, respectively. In contrast, the tree scenario exhibited the most significant improvement. The average temperature, MRT, and PET decreased by 0.03°C, 1.66°C, and 0.65°C, respectively. Moreover, the removal of vacant houses in dense residential areas improved ventilation, and PET decreased by approximately 8°C locally. Planting trees higher than the demolished vacant houses mitigated the thermal environment considerably. The effect of greening was the strongest in the residential areas located on the south-facing slope with the worst thermal environment. This study provides essential data for implementing greening as a smart reduction strategy in the sustainable management of vacant houses.
本研究旨在利用 ENVI-met 分析釜山广域市建筑密集的老城区通过绿化长期空置房屋和空地改善室外热环境的情况。考虑到建筑密度和坡度方向,在四个区域构建了四种情景,对夏日进行了模拟。结果表明,与当前情景相比,混凝土情景的热环境最差,平均温度、平均辐射温度(MRT)和生理当量温度(PET)分别上升了 0.04°C、1.49°C 和 0.51°C。相比之下,树木情景的改善最为显著。平均气温、MRT 和 PET 分别下降了 0.03°C、1.66°C 和 0.65°C。此外,拆除密集住宅区的空置房屋改善了通风,PET 在当地下降了约 8°C。在高于被拆除空置房屋的地方植树,可以大大缓解热环境。在热环境最差的南向斜坡住宅区,绿化效果最强。这项研究为在空置房屋的可持续管理中实施绿化这一智能减排策略提供了重要数据。

Evaluating the impact of social housing policies: Measuring accessibility changes when individuals move to social housing projects 评估社会住房政策的影响:衡量个人迁入社会住房项目后无障碍环境的变化

Addressing housing deficits and inequalities remains a key challenge for cities in promoting more sustainable urban development. In response to these challenges, governments around the world, particularly in the Global South, have made substantial investments in housing policies for middle- and low-income individuals. Nevertheless, while these initiatives increase housing provision, they often face criticism for not adequately considering the location of new residences. This oversight has far-reaching effects on the accessibility to essential facilities, which play a pivotal role in determining spatial advantages and disadvantages, and consequently, in the degree of inclusion of individuals in both the city and society. Addressing this critical role of accessibility, this paper introduces a methodology for assessing the potential impact of housing policies on the lives of their beneficiaries, by quantifying changes in cumulative accessibility levels between individuals' former house locations and the location of the housing projects into which they moved. Accessibility is calculated for three distinct transport modes: walking, cycling, and public transport, using unimodal and multimodal urban network models. A case study was conducted in Natal, northeastern Brazil, on the implementation of the Minha Casa, Minha Vida (My House, My Life, MCMV) housing policy, initiated in 2009 and still active today. The results of the study revealed a significant decrease in accessibility across all transportation modes when individuals moved to the new housing estates. The decline was particularly pronounced among individuals with lower incomes, potentially raising their regular expenses after relocation and, ultimately, leading to spatial isolation and social exclusion. These findings demonstrate the contribution of the methodology to capturing the impacts of housing policies on the everyday accessibility of their beneficiaries, while emphasizing the importance of re-evaluating these policies with a particular focus on fostering the social and urban inclusion of beneficiaries.
解决住房短缺和不平等问题仍然是城市在促进更可持续的城市发展过程中面临的主要挑战。为应对这些挑战,世界各国政府,尤其是全球南部国家的政府,在针对中低收入人群的住房政策方面进行了大量投资。然而,这些举措在增加住房供应的同时,也常常因为没有充分考虑新住宅的选址而受到批评。这种疏忽对基本设施的可达性产生了深远影响,而基本设施的可达性在决定空间优势和劣势,进而决定个人融入城市和社会的程度方面发挥着关键作用。针对可达性的这一关键作用,本文介绍了一种评估住房政策对其受益人生活的潜在影响的方法,即通过量化个人原住房所在地与他们迁入的住房项目所在地之间累积可达性水平的变化。利用单式和多式城市网络模型,对步行、骑自行车和公共交通三种不同交通方式的可达性进行了计算。在巴西东北部的纳塔尔进行了一项案例研究,内容是关于 2009 年启动、至今仍在实施的 "我的房子,我的生活"(Minha Casa, Minha Vida,MCMV)住房政策的实施情况。研究结果表明,个人搬入新住宅区后,所有交通方式的可达性都显著下降。这种下降在低收入人群中尤为明显,可能会增加他们搬迁后的日常开支,并最终导致空间隔离和社会排斥。这些研究结果表明,该方法有助于捕捉住房政策对其受益人日常交通便利性的影响,同时强调了重新评估这些政策的重要性,尤其要关注促进受益人的社会和城市融入。
