As cities introduce stricter CO2 regulations on urban transport, the logistics sector is rapidly adopting electric freight vehicles. While sustainable logistics is often framed as a matter of technical optimization, this paper highlights how emission-free last-mile operations are reshaping urban space and mobility. Focusing on the use of light electric freight vehicles (LEFVs) in the Netherlands, we examine how these vehicles interact with the spatial constraints of city centers, increasingly designated as Zero-Emission Zones. Drawing on 12 expert interviews at the Netherlands' largest logistics provider, we analyze how sustainability goals are interpreted and operationalized in practice, leading to infrastructural and procedural adjustments to meet diverse expectations from both the market and public authorities. While existing research tends to emphasize environmental and economic indicators of LEFV deployment, our findings foreground the socio-spatial dimensions, including its potential to ease traffic congestion and improve flows for cyclists and pedestrians. However, the demand for space to park, charge, and load LEFVs near city centers complicates their contribution to sustainable urban environment, despite being emission-free. By integrating insights from mobilities studies, logistical geographies, and urban planning literature, this study identifies the regulatory and spatial barriers that must be addressed to move beyond electrification toward “city-friendly” logistics. We conclude by arguing that logistics flows should be treated not only as operational or technological matters, but as critical components in the spatial planning and governance to support a broader transition toward sustainable urban mobility.
随着城市对城市交通实施更严格的二氧化碳排放规定,物流业正在迅速采用电动货运车辆。虽然可持续物流通常被定义为技术优化问题,但本文强调了无排放的最后一英里运营如何重塑城市空间和交通。以荷兰轻型电动货车(lefv)的使用为重点,我们研究了这些车辆如何与城市中心的空间限制相互作用,城市中心越来越多地被指定为零排放区。通过对荷兰最大的物流供应商的12位专家的访谈,我们分析了可持续发展目标是如何在实践中被解释和操作的,从而导致基础设施和程序的调整,以满足市场和公共当局的不同期望。虽然现有的研究倾向于强调LEFV部署的环境和经济指标,但我们的研究结果突出了社会空间维度,包括其缓解交通拥堵和改善骑自行车者和行人流量的潜力。然而,对城市中心附近停车、充电和装载空间的需求使它们对可持续城市环境的贡献变得复杂,尽管它们是零排放的。通过整合来自交通研究、物流地理和城市规划文献的见解,本研究确定了必须解决的监管和空间障碍,以便从电气化转向“城市友好型”物流。最后,我们认为,物流不仅应被视为运营或技术问题,而且应被视为空间规划和治理的关键组成部分,以支持向可持续城市交通的更广泛过渡。

Many U.S. localities use digital equity mapping in the form of Regional Equity Atlases (REAs) to inform the activities of policymakers and advocates. This article highlights lessons from our research leading up to and during an REA-building process in Central Virginia from 2018 to 2021 using constellation analysis (Ohlhorst & Schön, 2015). In the first section, we contextualize REAs by recounting a brief history of the intersections of geospatial mapping with regional and equity considerations within urban planning and policy. In the second section, we describe a field scan of existing REA platforms we conducted as in the 2018–2019 academic year. We assess the overall development of REA tools through modified constellation analysis in relation to an emerging body of planning scholarship around REAs. In the third section, we describe how we translated lessons from the field scan into a pilot REA and associated mapping and policy tools for a project in Central Virginia from 2018 to 2021. Our conclusion summarizes lessons we drew from these efforts in the context of accelerating shifts in the policy landscape and regional governance contexts in recent years.
美国许多地方都以地区公平地图集(REAs)的形式使用数字公平地图,为政策制定者和倡导者的活动提供信息。本文重点介绍了我们使用星座分析在2018年至2021年期间在弗吉尼亚州中部进行rea建设过程之前和期间的研究经验教训(Ohlhorst & Schön, 2015)。在第一部分中,我们通过叙述地理空间测绘与城市规划和政策中的区域和公平考虑的交叉点的简要历史,将REAs置于背景中。在第二部分中,我们描述了我们在2018-2019学年对现有REA平台进行的现场扫描。我们通过修改星座分析来评估REA工具的整体发展,该分析与围绕REA的新兴规划学术机构有关。在第三部分中,我们描述了如何将现场扫描的经验教训转化为试点REA以及相关的绘图和政策工具,用于2018年至2021年弗吉尼亚州中部的一个项目。我们的结论总结了近年来在政策格局和区域治理背景加速变化的背景下,我们从这些努力中吸取的经验教训。

Bike share systems promote sustainable transportation and active mobility. Understanding spatiotemporal usage patterns and influencing factors is crucial for equitable and effective policies. This study analyzes a full year of Global Positioning System-tracked bike share trip data from Hamilton, Ontario, to examine the travel behaviors of three membership types: Monthly and Seasonal Members, Pay-As-You-Go riders, and McMaster Monthly Pass holders. We employ descriptive statistics to analyze trip start times and the most frequently used routes, alongside a two-way fixed-effect binary logistic model to investigate bike share traffic at the road-and-day level, providing detailed insights into the determinants of bike share usage. Findings reveal that different membership types exhibit distinct spatiotemporal usage patterns and preferences regarding land use, infrastructure, sociodemographics, and events affecting bike-share road traffic. Only Monthly and Seasonal Members display consistent commuting patterns throughout the year. McMaster Monthly Pass holders dominate during the school semester following the introduction of a discounted pass for undergraduate students. Furthermore, Monthly and Seasonal Members are more likely to cycle on roads adjacent to parks, while McMaster Monthly Pass holders show lower sensitivity to extreme temperatures. Precipitation, darkness, slope, and holidays consistently deter bike share usage. Policy recommendations include expanding fare discount programs, improving wayfinding, organizing cycling events during holidays, and enhancing winter road maintenance for heavily used cycling routes. This study highlights differences in usage patterns, distinct preferences, and varying sensitivities to factors affecting bike share traffic flow among membership types, offering robust insights through a long study period and detailed road-level data.
共享单车系统促进了可持续交通和主动出行。了解时空使用模式和影响因素对于制定公平有效的政策至关重要。本研究分析了来自安大略省汉密尔顿市的一整年全球定位系统追踪的共享单车出行数据,考察了三种会员类型的出行行为:月票和季票会员、现收现付会员和麦克马斯特月票持有人。我们使用描述性统计来分析出行开始时间和最常用的路线,并使用双向固定效应二元logistic模型来调查道路和日水平的共享单车交通,从而详细了解共享单车使用的决定因素。研究结果表明,不同的成员类型在土地利用、基础设施、社会人口统计学和影响共享单车道路交通的事件方面表现出不同的时空使用模式和偏好。只有月度和季节性会员显示全年一致的通勤模式。麦克马斯特月卡(McMaster Monthly Pass)持有者在本科学生折扣通行证推出后的学期中占据主导地位。此外,月票和季票会员更有可能在公园附近的道路上骑车,而麦克马斯特月票持有人对极端温度的敏感性较低。降水、黑暗、斜坡和假期一直阻碍着共享单车的使用。政策建议包括扩大票价折扣计划、改进寻路系统、在假期组织自行车活动,以及加强对经常使用的自行车路线的冬季道路维护。本研究强调了不同会员类型在使用模式、不同偏好以及对影响共享单车交通流量因素的不同敏感性方面的差异,通过长期研究和详细的道路水平数据提供了强有力的见解。

This study analyzes seven decades of research on urban public space quality using bibliometric and scientometric methodologies. It identifies thematic trends, regional disparities, and methodological advancements, revealing a shift from foundational topics like urbanization and environmental sustainability to modern priorities such as smart cities, big data, and social equity. Through citation analysis, keyword mapping, and network clustering (e.g., Louvain algorithm), the study highlights critical research gaps and the dominance of developed regions, such as North America and Europe, in shaping discourse through technological innovation and interdisciplinary approaches. Developing and underdeveloped regions face challenges related to infrastructure, equity, and limited research visibility. The findings emphasize the need for inclusive, participatory, and technology-integrated research paradigms to tackle global challenges like urban resilience, climate change, and equitable public space access. The study proposes a conceptual framework for assessing urban public space quality, integrating regional specificities and development status. It advocates for international collaboration and capacity building to bridge development gaps, laying the groundwork for contextually relevant urban development strategies.

The spatial misallocation of land resources remains a major impediment to sustainable urban development, especially in rapidly transforming economies. The Yangtze River Delta (YRD), one of China's most economically dynamic region, provides a salient setting given its rapid urban expansion and heterogeneous policy regimes. The interplay between government and market forces in mitigating spatial misallocation of land resource has been a subject of ongoing debate. This study develops a conceptual framework to elucidate how market forces and government intervention interactively shape the spatial misallocation of urban land, and test it using panel data models for prefecture-level cities from 2006 to 2019. Our findings demonstrate that land marketization plays a pivotal role in mitigating spatial misallocation of urban land and incentivizes the efficient allocation of urban land. Government intervention exhibits a distinctive “U-shaped” relationship with misallocation: moderate intervention effectively alleviates land misallocation, whereas excessive intervention exacerbates the problem. Notably, the impact of these factors varies significantly across different cities. Overall, the evidence supports a context-sensitive balance between market mechanisms and government regulation to optimize urban land allocation and advance sustainable urban development.
土地资源的空间分配不当仍然是可持续城市发展的主要障碍,特别是在迅速转型的经济体中。长江三角洲(YRD)是中国最具经济活力的地区之一,由于其快速的城市扩张和异质的政策制度,提供了一个突出的环境。政府和市场力量在缓解土地资源空间错配方面的相互作用一直是争论的主题。本研究建立了一个概念框架,以阐明市场力量和政府干预如何相互影响城市土地空间错配,并使用2006 - 2019年地级市面板数据模型对其进行了检验。研究结果表明,土地市场化在缓解城市土地空间错配、促进城市土地有效配置方面发挥着关键作用。政府干预与土地错配呈明显的“u型”关系:适度干预有效缓解了土地错配问题,过度干预则加剧了土地错配问题。值得注意的是,这些因素的影响在不同城市之间差异很大。总体而言,证据支持市场机制和政府监管之间的情境敏感平衡,以优化城市土地配置和促进城市可持续发展。

As cities worldwide strive to become more age-friendly in response to rapidly aging populations, outdoor falls among older adults remain a persistent challenge that undermines these initiatives. The micro-scale environmental determinants of these falls remain inadequately explored, creating a significant gap in evidence-based urban design for inclusive urban environments. This study investigates the association between built environment features and outdoor fall risks among older adults using data from 6302 emergency dispatch cases in Jeonbuk Province, South Korea. By leveraging deep learning-based computer vision and a zero-inflated Poisson model, we analyze half a million street view images to identify micro-scale streetscape features associated with outdoor fall incidents. Our findings indicate that older adults are more likely to fall in areas with high population density and mixed-use land. While these environmental characteristics show higher fall incident rates, certain streetscape features, such as curbs and brick surfaces, can mitigate fall risks, while asphalt and concrete surfaces may exacerbate them. These findings demonstrate that environments promoting walking require enhanced fall risk management through appropriate design considerations for older adults. By recognizing older adults as ‘mobility minorities’ with specific needs, targeted micro-scale streetscape interventions, such as surface materials and curb designs, can enhance safety while preserving walkability benefits, supporting more inclusive urban environments.
随着世界各地的城市努力变得对老年人更加友好,以应对迅速老龄化的人口,老年人在户外摔倒仍然是一个持续的挑战,破坏了这些举措。这些瀑布的微观环境决定因素仍然没有得到充分的探索,在以证据为基础的包容性城市环境的城市设计中造成了巨大的差距。本研究利用韩国全北6302个紧急调度案例的数据,调查了建筑环境特征与老年人户外跌倒风险之间的关系。通过利用基于深度学习的计算机视觉和零膨胀泊松模型,我们分析了50万张街景图像,以识别与户外跌倒事件相关的微尺度街景特征。我们的研究结果表明,在人口密度高和混合用途土地的地区,老年人更容易跌倒。虽然这些环境特征显示出较高的跌倒发生率,但某些街景特征,如路边石和砖表面,可以减轻跌倒风险,而沥青和混凝土表面可能会加剧跌倒风险。这些发现表明,促进步行的环境需要通过对老年人适当的设计考虑来加强跌倒风险管理。通过认识到老年人是具有特定需求的“流动性少数群体”,有针对性的微尺度街景干预措施,如路面材料和路侧设计,可以在保持步行优势的同时提高安全性,支持更具包容性的城市环境。

Climate change adaptation in south Asian cities: A scoping review of literature from 2008 to 2022 南亚城市的气候变化适应:2008 - 2022年文献综述

South Asian cities, home to nearly 700 million people, are rapidly urbanising while facing intensifying climate impacts such as heatwaves, flooding, and sea-level rise. This paper presents a scoping review of 622 academic publications from 2008 to 2022, analysing how climate adaptation policymaking has been approached through non-structural and structural measures. Of these, 129 publications were analysed in depth, revealing a strong connection between extreme climate events and the resulting policy developments. The findings highlight a dominant focus on non-structural measures and secondary cities, yet also underscore how separating non-structural from structural interventions risks fragmenting adaptation strategies. This fragmentation can marginalise vulnerable communities, reflecting a market-based, technocratic governance model.

拥有近7亿人口的南亚城市正在快速城市化,同时面临着热浪、洪水和海平面上升等日益加剧的气候影响。本文对2008年至2022年期间的622份学术出版物进行了范围审查,分析了气候适应政策制定是如何通过非结构性和结构性措施进行的。其中,对129份出版物进行了深入分析,揭示了极端气候事件与由此产生的政策发展之间的密切联系。研究结果强调了对非结构性措施和二级城市的主要关注,但也强调了将非结构性干预与结构性干预分开可能会使适应战略支离破碎。这种分裂可能会使弱势群体边缘化,反映出一种以市场为基础的技术官僚治理模式。非正式性,特别是在城市周边地区,成为城市脆弱性的一个关键但尚未得到充分探索的方面。该评估呼吁开展包容性的适应工作,包括共同生产的知识和当地社区的积极参与,强调需要弥合结构性和非结构性方法之间的差距。通过整合非正式形式、加强治理能力和促进社会行动者之间的合作,政策制定者和实践者可以建立更加公平和有弹性的城市系统,有效应对南亚城市的气候挑战。

As programs and policies designed to improve urban health and sustainability have matured, many urban scholars question the fairness of their implementation. Our study addresses this issue by evaluating the association of census tract-level gentrification in New York City with both the creation or renovation of major green spaces and investment in a municipal brownfield Voluntary Cleanup Program (VCP). For each tract, we computed an index of gentrification based on the relative change of key input variables for the years 2000 through 2019. Using a 400-meter edge buffer for each tract, we then computed the percent overlap with major parks that were recently created or renovated and the number of properties remediated through the city's VCP program. The proportion of remediated VCP sites, relative to the number of properties designated with possible environmental hazards, was significantly higher among tracts in the top 20th percentile of gentrification, relative to tracts in the lowest 20th percentile (9.8 % vs 4.3 %, p-value <0.0001). Simultaneous autoregressive spatial error models, with or without adjusting for geographic strata (pre-determined from k-means clustering), revealed positive effects from the number of VCP sites, which were consistently strong (p < 0.001), and from park proximity (1 if any percent overlap, 0 otherwise), which were marginally significant (0.02 < p < 0.09) but which modified (p < 0.001) the effect of VCP sites. These quantitative results, together with geovisualization, document how the phenomenon of green gentrification may be associated with multiple interacting forces; plus certain sustainability initiatives may distribute environmental improvements unevenly, favoring neighborhoods undergoing redevelopment and subsequent gentrification.
随着旨在改善城市健康和可持续性的项目和政策的成熟,许多城市学者质疑其实施的公平性。我们的研究通过评估纽约市人口普查区级别的高档化与主要绿地的创建或翻新以及市政棕地自愿清理计划(VCP)的投资之间的关系来解决这一问题。对于每个区域,我们根据2000年至2019年关键输入变量的相对变化计算了士绅化指数。然后,我们对每个区域使用400米的边缘缓冲区,计算出与最近新建或翻新的主要公园重叠的百分比,以及通过城市VCP计划修复的物业数量。相对于可能存在环境危害的财产数量,在高档化程度最高的20个百分位数的土地中,修复的VCP场地的比例明显高于最低的20个百分位数(9.8% vs 4.3%, p值<;0.0001)。同时自回归空间误差模型,无论是否调整地理层(从k-means聚类中预先确定),都显示了VCP站点数量的积极影响(p < 0.001),这些站点的数量一直很强(p < 0.001),而公园邻近(如果有百分比重叠,则为1,否则为0),它们具有边际显著性(0.02 < p < 0.09),但修改了VCP站点的影响(p < 0.001)。这些定量结果与地理可视化一起,记录了绿色高档化现象如何与多种相互作用的力量相关联;此外,某些可持续发展倡议可能会不均衡地分配环境改善,有利于正在进行重建和随后的中产阶级化的社区。

Modelling human settlement growth and fringe patterns in the Andes through remote sensing and deep learning 通过遥感和深度学习模拟安第斯山脉人类住区增长和边缘格局

Cities in the Andean region are polycentric, spatially complex, often informal, characterised by limited data availability, and exhibit micro-scaled parcel sizes, these conditions have been scarcely studied and continue to pose challenges for the modelling of urban growth and the delimitation of the urban–rural fringe. To address these challenges, a deep ensemble model was developed, and multiscale spatial hierarchical methods were employed to define settlement agglomeration boundaries. The ensemble incorporated a dual U-Net, through which output approximating a Gaussian convolution of the expansion area were produced as a fuzzy mask, and a customised CNN uses it to generate the expanded urban footprint.
By this approach, current models limitations were overcome. Through multiscale spatial hierarchical analysis, 220 cities forming 165 agglomerations across the region were identified. Spectral indices, urban conditions, and inequality indices were contrasted, and a new urban boundary definition was proposed that more accurately reflected the dynamics of urban–rural fringe transitions and major interactions.
The findings indicated that inner urban conditions were strongly associated with change patterns in intermediate and large agglomerations, with effects detectable up to 3–4 km from the defined settlement boundaries. It was concluded that the proposed growth model and boundary definition provided a more robust framework for evaluating urban parameters in the Andean region.
安第斯地区的城市是多中心的、空间复杂的、通常是非正式的、以有限的数据可得性为特征,并表现出微尺度的包裹大小,这些条件几乎没有得到研究,并继续对城市增长的建模和城乡边界的划定构成挑战。为了解决这些问题,本文建立了一个深度集成模型,并采用多尺度空间分层方法来定义沉降集聚边界。该集成集成了一个双U-Net,通过它产生近似于扩展区域的高斯卷积的输出作为模糊掩模,定制的CNN使用它来生成扩展的城市足迹。通过这种方法,克服了现有模型的局限性。通过多尺度空间层次分析,确定了区域内形成165个城市群的220个城市。对比了光谱指数、城市条件指数和不平等指数,提出了更准确反映城乡边缘变迁动态和主要相互作用的新的城市边界定义。研究结果表明,城市内部条件与中大型聚集的变化模式密切相关,其影响可在距离确定的聚落边界3-4公里处检测到。结论是,拟议的增长模型和边界定义为评价安第斯地区的城市参数提供了一个更有力的框架。
