Built environment characteristics can greatly influence pedestrians' route choices with factors beyond distance, such as accessibility, convenience, safety, and aesthetics, playing crucial roles. Although current navigation apps, such as Google Maps and Waze, have successfully provided driving directions, their navigation services are insufficient and sometimes unrealistic for addressing pedestrians' needs, largely due to the lack of dedicated pedestrian networks and the associated navigation algorithms. To address the research gaps, this paper proposes a novel approach that integrates freely available geospatial data and computer vision technology to create a specialized inclusive network dataset for outdoor pedestrian navigation. Moreover, a pedestrian navigation algorithm is developed to generate more practical “shortest” and “alternative” paths by incorporating various sidewalk attributes. We applied the method to create a pedestrian navigation network in Las Vegas. SpaceNet's open imagery dataset was used to extract Las Vegas's road networks. A virtual audit process assessed the visual and operational properties of the sidewalk networks using Google street-level images, evaluating factors including sidewalk presence, widths, surface types and conditions, missing curb ramps, greenery, protection from weather conditions, and lighting. Google Earth's open elevation data were used to analyze road elevation profiles as meaningful 3D indicators of sidewalk accessibility for wheelchair users. Further, additional geometric properties of the network, including road curviness, proximity to road intersections, and directional changes, were detected and analyzed. A navigation experiment conducted with individuals having varying mobility abilities, including regular pedestrians, older adults, and wheelchair users demonstrated the effectiveness of the newly developed network and algorithm in meeting the diverse needs of pedestrians.
建筑环境特征在很大程度上会影响行人的路线选择,除距离因素外,诸如可达性、便利性、安全性和美观性等因素也起着至关重要的作用。尽管谷歌地图和 Waze 等当前的导航应用程序已经成功地提供了行车导航,但它们的导航服务不足以满足行人的需求,有时甚至是不切实际的,这主要是由于缺乏专门的行人网络和相关的导航算法。为弥补研究空白,本文提出了一种新方法,将免费提供的地理空间数据与计算机视觉技术相结合,为户外行人导航创建专门的包容性网络数据集。此外,本文还开发了一种行人导航算法,通过结合人行道的各种属性,生成更实用的 "最短 "和 "备选 "路径。我们应用该方法在拉斯维加斯创建了一个行人导航网络。SpaceNet 的开放图像数据集用于提取拉斯维加斯的道路网络。虚拟审核流程利用谷歌街景图像对人行道网络的视觉和运行属性进行评估,评估因素包括人行道的存在、宽度、表面类型和状况、缺失的路边坡道、绿化、免受天气条件影响以及照明。谷歌地球的开放式高程数据被用来分析道路高程剖面,作为轮椅使用者无障碍通行人行道的有意义的三维指标。此外,还检测和分析了网络的其他几何特性,包括道路弯曲度、与道路交叉口的距离和方向变化。通过对不同行动能力的个人(包括普通行人、老年人和轮椅使用者)进行导航实验,证明了新开发的网络和算法在满足行人不同需求方面的有效性。

Indoor navigation systems often rely on verbal, turn-based route instructions. These can, at times, be ambiguous at complex decision points with multiple paths intersecting under angles that are not well distinguished by the turn grammar used. Landmarks can be included into turn instructions to reduce this ambiguity. Here, we propose an approach to optimize landmark allocation to improve the clarity of route instructions. This study assumes that landmark locations are constrained to a pre-determined set of slots. We select a minimum-size subset of the set of all slots and allocate it with landmarks, such that the navigation ambiguity is resolved. Our methodology leverages computational geometric analysis, graph algorithms, and optimization formulations to strategically incorporate landmarks into indoor route instructions. We propose a method to optimize landmark allocation in indoor navigation guidance systems, improving the clarity of route instructions at complex decision points that are inadequately served by turn-based instructions alone.
室内导航系统通常依赖于口头的转弯路线指示。在复杂的决策点,多条路径在角度上相交,而所使用的转弯语法并不能很好地区分这些角度,因此这些指示有时会很模糊。可以在转弯指示中加入地标,以减少这种模糊性。在此,我们提出了一种优化地标分配的方法,以提高路线指示的清晰度。本研究假设地标位置受限于一组预先确定的插槽。我们从所有插槽集合中选择一个最小尺寸的子集,并为其分配地标,从而解决导航模糊问题。我们的方法利用计算几何分析、图算法和优化公式,战略性地将地标纳入室内路线指示中。我们提出了一种在室内导航引导系统中优化地标分配的方法,提高了复杂决策点路线指示的清晰度,而这些决策点仅仅依靠基于转弯的指示是不够的。

Research has underscored the role that social infrastructure - the places and spaces that help build and maintain social ties - plays in improving quality of life, lowering crime, and creating connection. Little work to date has shown how, across multiple urban environments, these parks, community centers, cafes, mosques, libraries, and other facilities correlate with bonding, bridging, and linking social capital. Our paper seeks to better understand the relationship between social infrastructure and bonding, bridging, and linking social capital along with inter-city differences in social facilities. We use Google map data from 25 urban centers in North America along with information from census-tract level Social Capital Index (SoCI) scores to map out these connections. We find that, controlling for other factors, social infrastructure positively correlates with bridging social capital - the weak or thin ties that build heterogeneous groups. As intended, many forms of social infrastructure help people engage with broader and more diverse networks, that is, provide a structure for connective democracy. Further, some cities' residents have extensive access to social infrastructure - such as those of Washington DC - while in others, such as Los Angeles, have far less. These findings bring with them policy recommendations for communities, NGOs, and decision makers alike.
研究强调了社会基础设施--有助于建立和维持社会联系的场所和空间--在提高生活质量、降低犯罪率和建立联系方面的作用。迄今为止,很少有研究表明,在多种城市环境中,这些公园、社区中心、咖啡馆、清真寺、图书馆和其他设施是如何与纽带、桥梁和联系社会资本相关联的。我们的论文旨在更好地理解社会基础设施与粘合、连接和联系社会资本之间的关系,以及城市间社会设施的差异。我们利用来自北美 25 个城市中心的谷歌地图数据以及人口普查区级社会资本指数(SoCI)得分信息来描绘这些联系。我们发现,在控制其他因素的情况下,社会基础设施与桥接性社会资本--建立异质群体的弱联系或薄联系--呈正相关。正如我们所预期的那样,许多形式的社会基础设施有助于人们与更广泛、更多样化的网络接触,也就是说,为连通性民主提供了一个结构。此外,一些城市的居民拥有广泛的社会基础设施,如华盛顿特区的居民,而在另一些城市,如洛杉矶,居民拥有的社会基础设施则少得多。这些发现为社区、非政府组织和决策者带来了政策建议。

In an era of increased climatic disasters, there is an urgent need to develop reliable frameworks and tools for evaluating and improving community resilience to climatic hazards at multiple geographical and temporal scales. Defining and quantifying resilience in the social domain is relatively subjective due to the intricate interplay of socioeconomic factors with disaster resilience. To broaden upon it, the choice of indicators and their subsequent ranking for the aggregation into an index is subjective in nature. This aggregation is not empirically validated and is prone to omit the nuances of localized resilience changes and causal factors affecting it, while leading to oversimplified conclusions. Meanwhile, there is a lack of scientifically and computationally rigorous, user-friendly tools that can support customized resilience assessment with consideration of local conditions. This study addresses these gaps through the power of CyberGIS with three objectives: 1) To develop an empirically validated disaster resilience model - Customizable Resilience Inference Measurement (RIM), designed for multi-scale community resilience assessment and influential socioeconomic factors identification; 2) To implement a Platform for Resilience Inference Measurement and Enhancement (PRIME) module in the CyberGISX platform backed by high-performance computing, enabling users to apply and customize RIM to compute and visualize disaster resilience; 3) To demonstrate the utility of PRIME through a representative study to understand the geographical disparities of county-level community resilience to natural hazards in the United States and identifying the driving factors of resilience in the social domain. Customizable RIM generates vulnerability, adaptability, and overall resilience scores derived from empirical parameters—hazard threat, damage, and recovery. Computationally intensive Machine Learning (ML) methods are employed to explain the intricate relationships between these scores and socioeconomic driving factors. PRIME provides a web-based notebook interface guiding users to select study areas, configure parameters, calculate and geo-visualize resilience scores, and interpret socioeconomic factors shaping resilience capacities. A representative study showcases the efficiency of the platform while explaining how the visual results obtained may be interpreted. The essence of this work lies in its comprehensive architecture that encapsulates the requisite data, analytical and geo-visualization functions, and ML models for resilience assessment. This setup provides a foundation for assessing resilience and strategizing enhancement interventions.
在气候灾害日益增多的时代,迫切需要开发可靠的框架和工具,以评估和提高社区在多种地理和时间尺度上抵御气候灾害的能力。由于社会经济因素与抗灾能力之间错综复杂的相互作用,社会领域抗灾能力的定义和量化相对主观。更进一步说,指标的选择和随后的排序以汇总成指数也是主观性的。这种汇总没有经过经验验证,容易忽略当地抗灾能力变化的细微差别以及影响抗灾能力的因果因素,从而得出过于简单的结论。同时,还缺乏科学和计算严谨、用户友好的工具来支持考虑当地条件的定制化复原力评估。本研究通过 CyberGIS 的强大功能来弥补这些不足,其目标有三个:1)开发一个经过经验验证的抗灾能力模型--可定制的抗灾能力推理测量(RIM),用于多尺度社区抗灾能力评估和有影响的社会经济因素识别;2)在 CyberGISX 平台中实施抗灾能力推理测量和增强平台(PRIME)模块,以高性能计算为支撑,使用户能够应用和定制 RIM,计算和可视化抗灾能力;3) 通过一项具有代表性的研究,展示 PRIME 的实用性,以了解美国县级社区抵御自然灾害能力的地理差异,并确定社会领域抵御能力的驱动因素。可定制的 RIM 可生成脆弱性、适应性和总体复原力分数,这些分数来自经验参数--灾害威胁、损害和恢复。计算密集型机器学习(ML)方法用于解释这些分数与社会经济驱动因素之间错综复杂的关系。PRIME 提供了一个基于网络的笔记本界面,指导用户选择研究区域、配置参数、计算复原力分数并将其地理可视化,以及解释影响复原力的社会经济因素。一项具有代表性的研究展示了该平台的效率,同时解释了如何解读所获得的可视化结果。这项工作的精髓在于其全面的架构,囊括了复原力评估所需的数据、分析和地理可视化功能以及 ML 模型。这种设置为评估复原力和制定增强干预措施的战略奠定了基础。

Urban densification is promoted for sustainable urban growth, yet it also generates concerns about negative health impacts on local citizens. Engaging local citizens in the co-design of densification projects is therefore crucial to address their needs and concerns. The use of immersive Virtual Reality (VR) technologies creates potential for advancing the participatory co-design of healthier urban spaces by allowing citizens to not only visualize but also experience the impacts of future designs or “what-if” scenarios. Theoretically grounded in an extended version of Sheppard's approach, which we call the Experiencing the Future Framework (EFF), we developed a study to create and evaluate an immersive VR application called CoHeSIVE. This application was designed to facilitate participatory co-design processes for healthy public spaces. CoHeSIVE, as the technological manifestation of our framework, was created through iterative workshops with end-user input. During the final workshop with 41 participants, both qualitative and quantitative data were collected, including user behavior and experiences with CoHeSIVE, especially regarding its experiential and interactive components. The vast majority of participants had positive experiences and recommended CoHeSIVE for participatory co-design processes. Participants felt confident in their design outcomes and found the user interface easy to use and effective for making and communicating design decisions. The most preferred design attributes were found to be many and clustered trees, several benches, large grass areas, high-rise buildings, more lampposts and the presence of a fountain, showing that the design outcomes were meaningful for the selected local context. Future enhancements of CoHeSIVE might include adding more design attributes, enhancing visual representations, adding multi-user capabilities, integrating generative AI and expanding CoHeSIVE's applicability to other contexts.
城市密集化是为了城市的可持续发展而提倡的,但它也引发了对当地市民健康负面影响的担忧。因此,让当地市民参与密集化项目的共同设计对于解决他们的需求和担忧至关重要。沉浸式虚拟现实(VR)技术的使用为推进参与式共同设计更健康的城市空间创造了潜力,它不仅能让市民直观地看到,还能让他们体验未来设计或 "假设 "情景的影响。我们以 Sheppard 方法的扩展版本(我们称之为 "体验未来框架"(EFF))为理论基础,开展了一项研究,以创建和评估名为 CoHeSIVE 的沉浸式 VR 应用程序。该应用旨在促进健康公共空间的参与式共同设计过程。CoHeSIVE 作为我们框架的技术表现形式,是通过与最终用户意见反馈的迭代研讨会创建的。在有 41 名参与者参加的最后一次研讨会上,我们收集了定性和定量数据,包括用户行为和使用 CoHeSIVE 的体验,特别是其体验和互动部分。绝大多数参与者都获得了积极的体验,并推荐CoHeSIVE用于参与式协同设计过程。参与者对自己的设计成果充满信心,认为用户界面易于使用,并能有效地做出和传达设计决策。参与者最喜欢的设计属性是树木多且密集、有多个长凳、有大片草地、有高层建筑、有更多灯柱和喷泉,这表明设计成果对所选的当地环境是有意义的。CoHeSIVE未来的改进可能包括增加更多的设计属性、增强可视化表达、增加多用户功能、整合生成式人工智能以及将CoHeSIVE扩展到其他环境中。

Informal participation in digital planning: How can third parties use social media to shift power relations in planning? 数字规划中的非正式参与:第三方如何利用社交媒体改变规划中的权力关系?

In recent years, social media has become an influential tool for engaging various participants and facilitating inclusivity in digital planning. While many studies highlight local governments' use of social media for formal participation, limited research assesses its impact on power dynamics in informal participation. This study aims to fill the gap by identifying key features of social media that facilitate informal participation and applying Castells' four forms of network power to understand power dynamics among civil society, journalism, citizens, and governments in planning processes. It also develops a novel mixed-methods approach that combines social media scraping, social network analysis (SNA), semi-structured interviews, and field observation. This approach is applied to investigate the Enning Road regeneration project in Guangzhou as a case study. Analyzing data from China's Weibo, the study reveals network disputes across three dimensions: graph, community, and network statistics. Hyperlink-Induced Topic Search (HITS) and community detection results suggest that civil society and journalism have substantial networked power as they strategically utilize social media to promote collaboration, mobilize citizens, and foster communities. They also excise network-making power by switching online and offline networks, thereby transmitting online debate to a wide range of audiences and compelling local governments to shift planning priorities from demolitions to preservation.

近年来,社交媒体已成为数字规划中吸引各种参与者和促进包容性的一种有影响力的工具。虽然许多研究强调了地方政府在正式参与中使用社交媒体的情况,但对其在非正式参与中对权力动态的影响进行评估的研究却很有限。本研究旨在通过识别社交媒体促进非正式参与的关键特征,并运用卡斯特尔斯的四种网络权力形式来了解规划过程中公民社会、新闻业、公民和政府之间的权力动态,从而填补这一空白。报告还开发了一种新颖的混合方法,将社交媒体搜索、社交网络分析 (SNA)、半结构式访谈和实地观察相结合。本研究以广州恩宁路改造项目为案例进行研究。通过分析中国微博的数据,该研究从图谱、社区和网络统计三个维度揭示了网络争端。超链接诱导主题搜索(HITS)和社区检测结果表明,民间社会和新闻业拥有巨大的网络力量,因为它们战略性地利用社交媒体来促进合作、动员公民和培育社区。他们还通过切换在线和离线网络来激发网络制造力,从而将在线辩论传递给广泛的受众,并迫使地方政府将规划重点从拆除转向保护。

It also develops a novel mixed-methods approach that combines social media scraping, social network analysis (SNA), semi-structured interviews, and field observation. This approach is applied to investigate the Enning Road regeneration project in Guangzhou as a case study. Analyzing data from China's Weibo, the study reveals network disputes across three dimensions: graph, community, and network statistics. Hyperlink-Induced Topic Search (HITS) and community detection results suggest that civil society and journalism have substantial networked power as they strategically utilize social media to promote collaboration, mobilize citizens, and foster communities. They also excise network-making power by switching online and offline networks, thereby transmitting online debate to a wide range of audiences and compelling local governments to shift planning priorities from demolitions to preservation.</p></div>","PeriodicalId":48241,"journal":{"name":"Computers Environment and Urban Systems","volume":"114 ","pages":"Article 102193"},"PeriodicalIF":7.1,"publicationDate":"2024-09-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S0198971524001224/pdfft?md5=fda3a0b26728ec11b0256b8e00a39944&pid=1-s2.0-S0198971524001224-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142241139","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The COVID-19 pandemic, unprecedented in scale and impact, has significantly influenced consumer spending. This study leverages a longitudinal transaction dataset from South Korea to analyze how the pandemic, social distancing policies, and pandemic-related search interest have shaped spending within and across cities. We examine transaction volume and expenditure amount as city-level indicators of activity intensity and consumption demand across four stages of the early pandemic. The study finds that: (1) Social distancing caused reductions in both residents' and travelers' spending. The increase in search interest coincided with a rise in residents' spending but a decline in travelers' spending; (2) Resident transactions experienced a moderate and persistent decline across all stages, while expenditure rebounded after the 1st national outbreak. Traveler transactions and expenditure showed similar trends, with declines during outbreaks and recoveries during stable periods; (3) Disparities across cities were associated with proximity to outbreak centers and socioeconomic attributes. Cities with larger populations or those closer to epicenters experienced greater reductions in spending, while less densely populated cities saw increased traveler spending during the 2nd stable period; (4) Travelers' spending from distant cities significantly decreased during the 1st outbreak but gradually recovered as the pandemic continued, indicating evolving behavior and adaptation; (5) Changes across spending categories exhibited significant heterogeneity. Residents showed increased demand for essential goods and online shopping, while recreation-related industries struggled throughout. These findings highlight the characteristics and disparities among consumers, cities, and industries, providing information for policymakers to formulate tailored support programs for industries experiencing increased demand or significant impacts. This study emphasizes the need to develop robust strategies for crisis management and economic resilience to mitigate the impacts of future health crises.

COVID-19 大流行在规模和影响上都是前所未有的,对消费者的消费产生了重大影响。本研究利用韩国的纵向交易数据集,分析了大流行病、社会疏远政策以及与大流行病相关的搜索兴趣如何影响了城市内和城市间的消费。我们研究了大流行初期四个阶段的交易量和支出额,将其作为活动强度和消费需求的城市级指标。研究发现(1) 社会疏远导致居民和旅行者的消费减少。搜索兴趣的增加与居民消费的增加和旅行者消费的下降相吻合;(2) 居民交易在所有阶段都经历了温和而持续的下降,而支出在第一次全国性疫情爆发后出现反弹。旅行者的交易额和支出呈现出类似的趋势,在疫情爆发期间下降,而在稳定时期恢复;(3)城市之间的差异与是否靠近疫情爆发中心和社会经济属性有关。人口较多的城市或离震中较近的城市支出减少较多,而人口密度较低的城市在第二个稳定期的旅客支出有所增加;(4) 远方城市的旅客支出在第一次疫情爆发期间显著减少,但随着疫情的持续而逐渐恢复,这表明旅客的行为和适应能力在不断发展;(5) 各类支出的变化表现出显著的异质性。居民对生活必需品和网上购物的需求增加,而与娱乐相关的行业则始终处于困境。这些发现凸显了消费者、城市和行业之间的特点和差异,为政策制定者提供了信息,以便为需求增加或受到重大影响的行业制定有针对性的支持计划。本研究强调,有必要制定强有力的危机管理和经济恢复战略,以减轻未来健康危机的影响。

Vehicle telemetry data is becoming more ubiquitous with increasingly sensorised vehicles, but making sense of the vehicles' purpose remains challenging without additional context. Clustering the vehicle activity data and identifying the underlying facilities where the activities occur reveals much insight, particularly for logistics planning. Unfortunately, current research typically only looks at a single point in time. This paper contributes by matching geospatial patterns, each representing a facility where trucks perform activities over multiple periods. The contribution is a necessary first step in studying how urban freight movement and its underlying inter-firm networks of connectivity change over time. We demonstrate how to overcome three challenges. Firstly, the complexity of identifying facilities from non-regular geometric polygons. Secondly, the challenge associated with the scale of comparing more than 200,000 facilities on a month-to-month basis over a multi-year period. Finally, overcoming the computational challenge of the workflow and getting the required performance on a consumer-grade laptop. The paper evaluates various machine learning algorithms, highlighting a SVM that outperforms more popular deep learning and neural network alternatives, with a mean average accuracy of 96.9 %.

随着车辆传感器化程度的不断提高,车辆遥测数据变得越来越普遍,但如果没有更多的背景信息,要了解车辆的用途仍然具有挑战性。对车辆活动数据进行聚类,并确定活动发生的底层设施,可以为物流规划提供更多启示。遗憾的是,目前的研究通常只关注单个时间点。本文的贡献在于匹配地理空间模式,每个模式都代表卡车在多个时间段内开展活动的设施。这是研究城市货运及其背后的企业间连通网络如何随时间变化的必要的第一步。我们展示了如何克服三个挑战。首先,从非规则几何多边形中识别设施的复杂性。其次,与在多年时间内逐月比较 20 多万个设施的规模相关的挑战。最后,克服工作流程的计算挑战,在消费级笔记本电脑上获得所需的性能。论文对各种机器学习算法进行了评估,其中 SVM 的平均准确率高达 96.9%,优于更常用的深度学习和神经网络算法。

The post-disaster recovery system is composed of the complex interplay between physical and social infrastructures. Despite the rise of coupled physical and social post-disaster recovery systems, less attention has been paid to the interdependent role of social support ties and physical infrastructure. This paper analyzes the data-driven models of post-disaster recovery system dynamics with the interdependence between the social and physical coupling to assess the post-disaster recovery policies. This paper utilizes the large-scale mobile phone location data, power outages, and socio-economic attributes for modeling the recovery dynamics during Hurricane Harvey in 2017. Parameter estimation results show that the model has regional heterogeneity and disparate impacts on socio-economic attributes to the model. The model's budget allocation scenarios also demonstrate that different budget allocation strategies affect the recovery period. The proposed model emphasizes the complex properties of the post-disaster recovery system and the importance of heterogeneous recovery policies across regions.

灾后恢复系统由物质基础设施和社会基础设施之间复杂的相互作用构成。尽管物理和社会耦合的灾后恢复系统正在兴起,但人们较少关注社会支持纽带和物理基础设施的相互依存作用。本文分析了灾后恢复系统动态的数据驱动模型与社会和物理耦合之间的相互依存关系,以评估灾后恢复政策。本文利用大规模手机定位数据、断电和社会经济属性,对2017年飓风哈维期间的灾后恢复动态进行建模。参数估计结果表明,模型具有区域异质性,社会经济属性对模型的影响也不尽相同。模型的预算分配方案也表明,不同的预算分配策略会影响恢复期。所提出的模型强调了灾后恢复系统的复杂属性以及不同地区异质性恢复政策的重要性。

Up till now, a widely accepted definition of Digital Planning is missing. Following the Editorial, digital planning is defined as the application of digital technologies and data-driven approaches to enhance efficiency, effectiveness, and inclusivity in planning processes to improve social, economic, and environmental outcomes for a sustainable urban future. It is necessary to clarify the distinction between Digital Planning and two associated terminologies: Planning Support Systems (PSS) and Planning Support Science (PSScience). PSScience and Digital Planning (DP) are envisioned as distinctive but closely interconnected. PSScience acts as the scientific base of the foremost planning practice-oriented Digital Planning. Based on this double-sided distinction and interconnection with PSScience, the relatively new concept of Digital Planning is further elaborated upon, resulting in an integrated research and practice agenda. For both approaches, a quadruple collaboration will be needed between governmental organizations, market parties, societal organizations/individuals, and educational/research institutes.

迄今为止,"数字规划 "还没有一个广为接受的定义。根据《社论》,数字规划被定义为应用数字技术和数据驱动方法,提高规划过程的效率、效益和包容性,从而改善社会、经济和环境成果,实现可持续的城市未来。有必要澄清数字规划与两个相关术语之间的区别:规划支持系统(PSS)和规划支持科学(PSScience)。规划支持科学(PSScience)和数字规划(DP)被认为是截然不同但又密切相关的两个概念。规划支持科学是以规划实践为导向的数字规划的科学基础。基于与 PSScience 的这种双面区别和相互联系,数字规划这一相对较新的概念得到了进一步阐述,从而形成了一个综合的研究和实践议程。这两种方法都需要政府组织、市场各方、社会组织/个人以及教育/研究机构之间的四重合作。
