This paper examines the effects of an investment in light rail transit on single-family property values in Montgomery County, Maryland, with a focus on when and where such capitalization takes place and with intent to inform efforts to promote equitable transit-oriented development. We employ both hedonic price and repeat-sales estimation techniques to assure the results are robust. The findings indicate that housing prices, after the light rail transit went into the engineering phase, rose with proximity to anticipated new rail stations but not with proximity to existing metro stations. For planners and policymakers and advocates in Montgomery County, the results provide critical information about where and when value capture and anti-displacement policies are most needed and potentially effective.

Urban artificial intelligence (UAI) refers to the development and deployment of artificial intelligence (AI) technologies and solutions in urban settings such as energy management, environmental monitoring, public safety, transportation, and predictive maintenance. Urban research has shifted from a data-scarce to a data-rich environment in recent years. Big data and computational algorithms have become continually integrated into the built environment and within human’s daily lives, leading to a significant rise in digital twin research. Heterogeneous real-time data can be synthesized from a wide range of sources such as sensors and cameras connected to buildings, factories, green spaces, roads, sidewalks, and other urban elements. Defined as a virtual representation of a physical urban environment, digital twins can be employed to analyze, model, and simulate various aspects of urban phenomena in the fine scale. The UAI will take the source data from sensors, satellite imagery, and social media over space, time, and scale as inputs, and generate outputs that typically include predictions or simulations of how urban elements or systems will be affected by these inputs. Powered by UAI, the bi-directional flow of data between a digital twin and the physical urban environment further allows the digital twin to both reflect the current state of the city and make more informed decisions about how to optimize the urban operation (Ye et al. 2022). Furthermore, the revolution of computing power and information technology has blurred the boundary across disciplines and urban applications. Linked with immersive technologies such as virtual reality (VR) and augmented reality (AR), UAI helps people to visualize cities as they change by showing how planning and infrastructure design can alter the urban environment reflecting the diverse perspectives and needs of the community, either positively or negatively. Collaboration across disciplines and stakeholders is often essential for addressing complex urban problems. UAI has the potential to help bridge the silos within design, social, and engineering sciences as well as growing gaps between research and practice, through activities such as citizen science, community-based research, and participatory research. UAI is revolutionizing urban planning education and practice by providing new tools for planners to automate certain tasks and make informed decisions (Sanchez et al. 2022). This allows planners to focus on more creative aspects of their work and efficiently evaluate large amounts of design options, ensuring that the final delivery is an optimized solution. Simultaneously, UAI enables a collective understanding of existing urban conditions and demonstrates innovative capabilities for how to increase cyber, social, and physical resilience and efficacy beyond simple technology integration. However, UAI could possibly exacerbate existing socioeconomic inequities in the built environment if such technical str
城市人工智能(UAI)是指在城市环境中开发和部署人工智能(AI)技术和解决方案，如能源管理、环境监测、公共安全、交通和预测性维护。近年来，城市研究从数据稀缺环境转向了数据丰富环境。大数据和计算算法已经不断融入建筑环境和人类的日常生活中，导致数字双胞胎研究的显著增加。异构实时数据可以从广泛的来源合成，例如连接到建筑物、工厂、绿地、道路、人行道和其他城市元素的传感器和摄像头。数字孪生被定义为城市物理环境的虚拟表现，可用于在精细尺度上分析、建模和模拟城市现象的各个方面。UAI将从传感器、卫星图像和社交媒体获取空间、时间和尺度上的源数据作为输入，并生成输出，通常包括预测或模拟这些输入对城市元素或系统的影响。在人工智能的支持下，数字孪生体和城市物理环境之间的双向数据流进一步使数字孪生体既能反映城市的当前状态，又能就如何优化城市运营做出更明智的决策(Ye et al. 2022)。此外，计算能力和信息技术的革命模糊了跨学科和城市应用的界限。UAI与虚拟现实(VR)和增强现实(AR)等沉浸式技术相结合，通过展示规划和基础设施设计如何改变城市环境，反映出社区的不同观点和需求，无论是积极的还是消极的，帮助人们可视化城市的变化。跨学科和利益相关者之间的合作对于解决复杂的城市问题往往至关重要。UAI有潜力通过公民科学、社区研究和参与性研究等活动，帮助弥合设计、社会和工程科学中的孤岛，以及研究与实践之间日益扩大的差距。通过为规划者提供自动化某些任务和做出明智决策的新工具，人工智能正在彻底改变城市规划教育和实践(Sanchez et al. 2022)。这使得规划人员可以专注于他们工作中更具创造性的方面，并有效地评估大量的设计方案，确保最终交付的是一个优化的解决方案。同时，UAI能够对现有城市条件进行集体理解，并展示了如何提高网络、社会和物理弹性和效率的创新能力，而不仅仅是简单的技术集成。然而，如果研究人员和从业者不以道德和负责任的方式设计和使用这种技术力量，人工智能可能会加剧建筑环境中现有的社会经济不平等。因此，需要利用人工智能来促进知识合作生产，这是指通过不同背景、经验和观点的人之间的积极合作来创造、共享和使用知识的包容性过程(Shrestha等人，2017)。在人工智能的推动下，知识联合生产可以通过数据收集、分析和传播的过程，让各种相关方参与进来，确定研究问题，共同设计/实施研究项目。此外，基于人工智能的知识合作生产可以帮助培养研究人员和当地居民之间的信任，并增加对其决策能力的信心，从而更全面和包容地了解他们所服务的社区的需求和优先事项。就数据短缺问题而言，特别是在低收入或资源不足的社区，可使用人工智能技术通过其他信息来源(例如公共数据集或来自公民科学的数据)来增加现有数据。UAI受其训练数据和所采用的算法的影响很大。因此，它继承了嵌入在这些数据和算法中的内置偏见。如果在决策过程中使用这种有偏见的人工智能，其潜在的不公平或歧视性结果可能会对个人或社会造成严重后果。因此，计划人员需要通过使用具有代表性的训练数据、以开源方式记录训练过程以及持续评估人工智能功能来减轻偏见。我们需要对用于训练UAI的数据和用于开发它的算法保持透明。对于开发人员来说，了解收集、管理和使用敏感数据的过程中涉及的数据伦理也很重要。 至关重要的是要确保数据收集得到有关个人的同意，并以负责任的方式使用数据。jjpexxx10 .1177/ 0739456x231154002规划教育与研究学报，编辑号:2023

This article examines the role of multilateral social and environmental safeguards in land acquisition for renewable energy (RE) development in Southeast Asia. We assessed the development of two large-scale wind projects in Indonesia and the Philippines through a qualitative comparative case study analysis. We find that the influence of safeguards is the product of two factors: the timing of multilateral funds in project development and the relative ease through which developers can acquire land through non-safeguard-compliant pathways. Our findings highlight the continued importance of land use policy and planning in mediating the social and environmental impacts of RE infrastructure.

American planning schools increasingly emphasize the global dimensions of planning pedagogy while also increasing enrollment from international students. However, few studies have examined how an American planning education serves the career development of international students, particularly those who return home. This study responds by exploring the experiences of students from mainland China who obtained a U.S. planning degree and then returned to work in China. Interviews with returnees highlight their struggles both in the United States and back home. Their experiences suggest opportunities to improve American planning schools’ pedagogy and services for Chinese and other students, domestic or international.

Planning theory scholars and practitioners have identified the need to include residents most affected by climate change in the development of climate adaptation planning, for reasons of justice and effectiveness. This article investigates whether Austin, Texas’ network of plans includes participation by residents and incorporation of local knowledge into climate adaptation. This research finds that these plans contain limited material about participation, engagement, equity, and local knowledge. In response to this gap, the article presents a case study of the Dove Springs Climate Navigators, a residents-nongovernmental organization-municipal-university collaboration working to co-create an online portal, training system, and process to incorporate local knowledge into adaptation planning.

There is a growing interest nationwide in employing a transportation utility fee (TUF). The extant literature discusses ways to make TUF legally defensible by maintaining its fee-like features, so that it is not considered a tax. However, courts consider the context of state law while determining the legality of a TUF; hence, the need to consider the takeaways from landmark TUF-related court cases and state-specific determinants while designing a TUF program. The paper begins to fill this research gap by demonstrating how court decisions can be overlaid on state-specific determinants to identify a set of choices for levying TUF.

This paper explores the link between African American civil rights activism and city planning before the 1965 Voting Rights Act. Using historical and spatial analyses, we discern the relationship between civil rights activism and leadership, voter registration, and city planning in Montgomery, Alabama, concluding—planning and African American activism and voting coevolved—with three distinct periods of planning and civil rights activism. The article suggests that housing demolition sought to curb potential political power through voting and civil rights activism alongside maintaining racial segregation and creating economic development in the postwar era.

Metropolitan areas are complex, dynamic spatial systems. This paper sets out a spatial analysis methodology suitable to address the internal complexity of metropolitan landscape change and which results could be useful for decision making in the context of sustainable land use planning. A two-scale approach is adopted for the analysis of recent land use changes in the metropolitan area of Seville (Spain), being the methodology applied to both the whole metropolitan area and two different landscape units. Distinct landscape change patterns and urban growth models are identified for the units studied. On the basis of the results, the convenience of a multiscale planning approach is highlighted.
