Shared autonomous vehicles (SAVs) are a major development direction in international scientific and technological innovation. One of the most popular features of SAVs in the urban space is that they can significantly reduce the need for parking. The urban underground parking space (UPS) is currently the largest static traffic space, especially in high-density urban centers. Under the SAV scenario, the need for the renewal of UPS will increase in the near future. However, renewal of the UPS is difficult due to its special form features, which are greatly restricted by the external environment, thus necessitating targeted methods and strategies. This research first conducted field investigations and data collection on the spatial morphology and service conditions of typical UPSs in different areas of Hangzhou city. Based on the driver status response and the multi-objective attribute models, the time-series evaluation method and function replacement decision model for the sustainable renewal of underground parking were established. The research also discusses appropriate design strategies for the combination of spatial characteristics and functional replacement goals of typical samples. The conclusions will provide scientific guidance for the future design practice of architects and urban designers in SAV.

Shared autonomous vehicles (SAVs) will be an important force to in reshaping urban morphology. The high operation rate and sharing degree of SAV are considered to result in a great reduction in parking area in future cities. Parking space is now a huge and widely distributed urban stock space type, which is bound to become a major challenge and opportunity for sustainable urban renewal in the digital era. Based on the SAV scenario, this paper reviews the current research on the sustainable renewal of urban public parking spaces, and proposes the four key issues involved: how much to renew (i.e., demand forecast analysis), when to renew (i.e., update time series evaluation), what to renew (i.e., function replacement decision) and how to update (i.e., design empirical research). Furthermore, it puts forward a preliminary idea on, and constructs a research framework for, the sustainable renewal methods of parking space under the SAV scenario. Finally, the theoretical, practical and policy implications of the research on sustainable renewal methods of urban public parking space are discussed. It will have great reference value for the redevelopment and reuse of the urban space types including fragmented, widely distributed and large-scale.

As current society’s reflection on the rapid development of motorization and increasing emphasis on the ecological environment, the study of walkable cities has become one of the key points of urban sustainable design. Creating a walkable city is an effective way to build a low-carbon and healthy city. With the development of cities, walkability concepts and theories are constantly being given new life, and research methods and design strategies continue to be updated. A city’s walkability and walkability index have become current research hotspots. Based on prior research on walkability and related urban policies, this study selects Coomera Town on the Gold Coast of Queensland, Australia, as the research area because of Coomera Town policy regulations and environmental requirements. This study utilizes traditional qualitative and quantitative research methods, machine mining technology, and the deep learning big data analysis technology to conduct thematic design research in a real place. Its combines walkability evaluation with walkability design to construct a walkable city in a targeted manner. This provides a reference for related city design in the future.

As fully automated valet parking systems are being developed, there is a transition period during which both human-operated vehicles (HVs) and autonomous vehicles (AVs) are present in the same parking infrastructure. This paper addresses the problem of allocation of a parking space to an AV without conflicting with the parking space chosen by the driver of a HV. A comprehensive assessment of the key factors that affect the preference and choice of a driver for a parking space is established by the fuzzy comprehensive method. The algorithm then generates a ranking order of the available parking spaces to first predict the driver’s choice of parking space and then allocate a space for the AV. The Floyd algorithm of shortest distance is used to determine the route for the AV to reach its parking space. The proposed allocation and search algorithm is applied to the examples of a parking lot with three designed scenarios. It is shown that parking space can be reasonably allocated for AVs.

This paper explores echolocation as a conceptual framework to extend our understanding of digital sociality. Echolocation is a process whereby the characteristics of an echo build a map of location and relation. Most often we think of how bats, whales, and dolphins echolocate to navigate. If we think of radar, sonar, or lidar, we might think of submarines, autonomous vehicles, or even geolocation on our mobile devices. In this paper, I discuss echolocation as a symbolic interaction framework for describing how the Self is negotiated and identified in and as a part of social space. It focuses attention on the character and function of pings, push notifications, red dots on device screens, and other responses in ongoing interactions between people in social media or between humans and nonhuman or more than human elements of media ecologies. The interpretive qualitative analysis is part of a six year ethnographic study of youth. The analysis of echolocation emerges from a subset of the larger study, those who feel anxiety and even existential vulnerability when disconnected. Based on this qualitative analysis of narratives, the paper builds and extends echolocation as a theory of digital sociality that pays close attention to the response versus the performance in the interaction model.

Geographic information systems can be defined as a intelligent tool, to which it relates techniques for the implementation of processes such as the introduction, recording, storage, handling, processing and generation of spatial data. Use of GIS in urban planning helps and guides planners for an orderly development of settlements and infrastructure facilities within and outside urban areas. Continued growth of the population in urban centers generates the need for expansion of urban space, for its planning in terms of physical and social infrastructures in the service of the community, based on the principles of sustainable development. In addition urbanization is accompanied with numerous structural transformations and functional cities, which should be evaluated in spatial context, to be managed and planned according to the principles of sustainable development. Urban planning connects directly with land use and design of the urban environment, including physical and social infrastructure in service of the urban community, constituting a challenge to global levels. Use of GIS in this field is a different approach regarding the space, its development and design, analysis and modeling of various processes occurring in it, as well as interconnections between these processes or developments in space.

Data from the International Energy Agency confirm that in a zero-energy perspective the integration of solar systems in buildings is essential. The development of passive solar strategies has suffered the lack of standard performance indicators and design guidelines. The aim of this paper is to provide a critical analysis of the main passive solar design strategies based on their classification, performance evaluation and selection methods, with a focus on integrability. Climate and latitude affect the amount of incident solar radiation and the heat losses, while integrability mainly depends on the building structure. For existing buildings, shading and direct systems represent the easiest and most effective passive strategies, while building orientation and shape are limited to new constructions: proper design can reduce building energy demand around 40%. Commercial buildings prefer direct use systems while massive ones with integrated heat storage are more suitable for family houses. A proper selection must consider the energy and economic balance of different building services involved: a multi-objective evaluation method represents the most valid tool to determine the overall performance of passive solar strategies.

“Gods outside the Walls” approaches the chief exception to the standard patterns of suburban development. Temples for the gods appeared outside Rome’s early colonies at Minturnae, Ostia, and Cosa already in the mid-Republican period, and certain examples, including a sanctuary at Hispellum and the shrine to Magna Mater in Rome’s Transtiberim, thrived through the fourth century CE. These spaces functioned in various ways, but indicate above all the enduring need for gods to protect and define all parts of a city, through even dramatic alterations to urban space. Early colonial sanctuaries oversaw not just urban expansion, but the active transformation of military outposts to urban centers, while the later temples survived the contraction of cities by reserving space for traditional modes of worship, even as a new force—Christianity—rose up to dominate Italy’s suburbs.

South Korea has industrialized and urbanized rapidly since the 1970s, and subsequently, the historic downtown areas of major cities have been hollowed out as the population and industry have become concentrated in urban centers. Based on the Urban Decline Indicators of Korea, in accordance with the Urban Revitalization Act of the South Korean government, a comparative analysis of the population changes, office vacancy rate, building aging rate, decrease in the number of industries and employees, and housing supply and demand in historic downtown areas and new urban areas of six major South Korean cities demonstrated that all six historic downtown areas have declined significantly. Currently, little research is available in South Korea on the expansion of urban living and the inflow of urban residents through office-to-residential building conversion. Therefore, this study explores the expansion of urban residences to revitalize these historic downtown areas. To this end, this study examines the feasibility of converting poorly functioning, vacant offices in historic downtown areas into residential spaces to present a sustainable strategy for their complexation. This study finds that office-to-residential building conversion is a sustainable way to recover urban space and grow the population and industry in historic downtown areas.
