    Hong Kong has long been a global benchmark for mass transit development. Nevertheless, the city’s urban development model, with rail as the backbone of public transport, underwent adaptation to fit different planning systems and regulatory frameworks when implemented overseas. Moreover, despite the growing body of studies focusing on station-area integration, no research has analysed pedestrian access to transit from an inter-urban, transit-system-wide comparative perspective. This study aims to fill such a research gap by focusing on Hong Kong and three mainland Chinese cities with well-developed Mass Rapid Transit (MRT) systems: Beijing, Shanghai, and Shenzhen (N = 1098 stations). A novel multi-source database was compiled and analysed; the analysis included a comprehensive set of indicators related to the physical connections (N = 4772) between the mass transit pedestrian environment and the overground urban realm. Results demonstrate that the Pedestrian Access to Transit (PAT) development in mainland Chinese cities differs from that in Hong Kong, where stations are often integrated with buildings. Such diverse integration reflects differences in service provider ownership, financial instruments, and dissimilar land allocation systems. PAT in mainland Chinese cities is primarily connected to outdoor public open space, shaping a peculiar pedestrian realm and end-user experience. This study advocates for dedicated urban design institutions focusing on the station-area pedestrian integration potential to promote, conceive, and implement climate-sensitive, culturally responsive, and universally accessible intermodal pedestrian connections.

    Promoted by sustainable urban agendas and urged by global pandemic measures, street experiments (SE) are booming in Europe but remain latent in Asia. These experiments aim to reconfigure streets as more than spaces for motorized traffic movements, enabling a temporary urban paradigm shift. Such a shift involves balancing active mobility and public space uses in streets while envisioning radically different settings and uses. Recently, eminent scholars urged considering SE in connection to the system and planning framework within which SE are conceived to trace their trajectories. This article examines four decades of temporary-pedestrianization policies and planning instruments in Hong Kong, an Asian city representative of high-density urban environments with highly intensive use of road space and conservative and prescriptive planning. In doing so, the article identifies four trajectories and illustrates two emblematic cases: Chater Road, the first street temporarily pedestrianized under a commercial initiative, and Sai Yeung Choi Street South, a street pedestrianized under a government initiative, now turned back to its original function. The competing roles and practical uses that pedestrianized streets must fulfil partially determined their fate. However, the trajectories these cases followed also differ due to the contextual planning approach and decision-making process. The study contributes to scholarship on SE by shedding new light on the geographical context of high-density urban Asia, forwarding challenges that policymakers might need to address in the planning and governance of SE in similar environments.

    This article retraces the impact of evolving hegemonic rapid transit planning and design strategies on pedestrian integration between stations and neighbourhoods, using Hong Kong as a longitudinal case. Mixed-methods research, triangulating documentary analysis, spatial analysis, and in-depth interviews, identified six typologies across three historical phases. The findings demonstrate that pedestrian access to transit is spatially heterogeneous, shaping the evolution of the station area from a connecting structure into an interconnecting infrastructure. Unfolding the historical interplay of hegemonic forces in the production of pedestrian spaces, this study innovatively bridges the research gap between planning policies and fine-grained urban design features.

    Pedestrianisation, the conversion of a vehicular street for pedestrian use, is increasingly being proposed worldwide as a sustainable measure by hegemonic powers. Pedestrianisation can bolster uneven urban development patterns, however social tensions can magnify on the pedestrianised street, where deprived social groups claim the right to the city. This study employs a mixed method approach to examine, within a de Certeausian theoretical framework, the relationship between the governmental strategies promoting pedestrianisation and the tactics of pedestrianised space informal appropriation. Within this context Hong Kong emerges as a revelatory case, it is a city where the extreme scarcity of public open space exacerbates the conflict between social groups interested in this resource. The analysis provides evidence of a discrepancy between expected and actual uses of the pedestrianised streets. Furthermore, this study highlights the need in the context of the global neoliberal city for discussing the theoretical dichotomy of strategies and tactics. This paper argues for pedestrian planning which includes stationary use as a main pedestrianisation objective, as well as for responsive urban design that carefully considers the association between behavioural patterns and spatial features of the pedestrianised street.

    In high-density Asian cities, the increasing scarcity of public open spaces gives rise to the need for stationary activities to tap into spaces originally conceived exclusively to channel pedestrian movements, such as grade separation pedestrian systems. However, the types and patterns of stationary activities on elevated walkways remain mostly unexplored. This study focuses on Hong Kong, wherein the scarcity of public open space characterises an extreme condition and where the burden of this scarcity falls most heavily on disadvantaged social groups, such as migrant workers. The findings highlight the prevalence of socially oriented activities and the importance of food as a gathering factor.Keywords: Grade separation pedestrian system; Elevated pedestrian network; Public open space; Migrant domestic worker; Hong KongeISSN 2514-751X © 2020 The Authors.

    Public spaces in Global East cities are socially hierarchical, with green and blue spaces often being reserved for affluent urbanites. In contrast, in Hong Kong, grey spaces are accessed by marginalised residents. On Sundays, female migrant domestic workers – typically invisible in the city – gather for collective leisure fitness in the grey spaces. Previous research has explored the affordances of various urban environments and their relationship with individual and social well-being. However, limited attention has been given to how grey spaces support diverse fitness activities. This article addresses that gap by examining how spaces that are materially and symbolically grey have been reclaimed and become social infrastructures through the collective fitness activities of migrant domestic workers in Hong Kong. Using qualitative methods, including participant observation and semi-structured interviews (N = 10), this study reveals how groups of migrant women have reclaimed city streets and the bare street infrastructure for collective Zumba dance. The study explores how these reclaimed grey spaces empower migrant domestic workers by fostering self-care, togetherness, and agency. By integrating scholarly discourses of chromatic leisure and grey spaces into socio-political transformations, our findings contribute to the understanding of social justice and inclusive urban design.

    Loneliness in high-density cities is increasingly being recognised as a public health crisis, but the role of built environments in shaping the feelings of loneliness and solitary experiences remains underexplored. This study investigates how socio-material networks in Hong Kong's public open spaces (POSs) co-construct solitary experiences and contribute to emotional well-being. Using a mixed-methods approach, including individual-centred behavioural mappings, on-site ethnographic interviews (n = 84), and multi-sensory experiential observations, this research reveals that POSs function as emotional refuges, enabling individuals to seek solitude for enjoyment, to escape domestic constraints, and to pause, rest, and reflect. The findings show that solitary experiences emerge through the interplay of human and non-human actants, including people, cultural norms, spatial settings, and environmental conditions. Spatial affordances such as shaded seating, visual seclusion, and proximity to transport networks significantly influence solitary practices. Moreover, POSs frequently serve as complements to other environments, offering respite from overcrowded and stressful home conditions and fast-paced working environments. This study highlights the need for urban planners to recognise solitude as a legitimate and valuable public space experience. It calls for POS designs that incorporate diverse spatial features to support both solitude and sociality, and it advocates for relational perspectives on socio-material networks in research and policy-making to address the emotional complexities of urban life.

    The prevailing paradigm in urban public open space (POS) design emphasises fostering social interaction; it overlooks the equally critical need for urban solitude, secrecy and privacy. In this study, we aim to address this gap by contextualising positive solitude (PS) in POSs within high-density urban environments and examining the spatial conditions that shape these experiences, using Hong Kong as a case study. Empirical research methods, including behavioural mapping and on-site participant observation, are used to investigate four POSs in Sham Shui Po, Kowloon City and Kwai Tsing. Through a comprehensive analysis of the role, function and utilisation of POSs, this research elucidates residents’ perceptions and practices of solitary space use, revealing that a significant proportion of Hong Kong POS users actively visit and utilise these spaces alone. Our analysis of how the physical and social characteristics of these spaces support PS experiences sheds light on the complex interplay between urban design elements and the fulfilment of residents’ solitude needs. This research provides an in-depth understanding of PS in a crowded urban setting, advocating for developing evidence-based POS design guidelines that consider appropriate support for PS behaviours and activities. Ultimately, this study contributes to the broader goal of creating more liveable and psychologically supportive urban environments, particularly in the context of high-density cities.

    This paper explores the collective mediated fitness practices of low-income migrant women in Hong Kong as practices of the Care of the Self. Little is known of how the widespread availability of smartphones and social media has changed the ways MDWs organise their social gatherings across time and diverse urban spaces. To explore the impacts of smartphone technologies on the spatiotemporal structuring of these care practices, we focus on three highly visible fitness groups: Zumba dance, yoga, and martial arts. Through semi-structured interviews and content analysis of MDWs’ social media activities, we analyse how digital tools support the operation of collective care practices, their presence in the urban space, and the relations between these activities and citizenship.

    Despite the growing body of work on how COVID-19 impacts the use of public space, few studies focused on vulnerable social groups. This article outlines a systematic analysis of the use of public space by migrant domestic workers before and after the pandemic outbreak in Hong Kong. The analysis reveals changes in behavioral patterns, and we discuss them as part of an ongoing conflictual renegotiation of rights and space alongside the dual nature of invisibility. The growing invisibility of migrant workers prompts unresolved questions of rights, spatial and recognitional justice, and acceptance of diversity in the global neoliberal city.

    Dancing on the asphalt: extending the bodies and materialities of chromatic leisure in Hong Kong

    Every child has the right to engage in play and recreational activities. Public play-spaces offer venues and opportunities for children to socially interact with their peers through play. The literature on inclusive play-space design has considered the needs of children with mind–body–emotional differences, who are the direct users. However, current research has not considered that these play-spaces are also used by children’s caregivers, who are of diverse ages and cultural backgrounds. Thus, the needs of these indirect users of play-spaces have rarely been assessed. In this systematic review, we address this issue by examining recent studies that focus on the needs and design factors related to both direct and indirect users of play-spaces from a children-caregiver perspective. Our review focuses on older adults, who represent a vulnerable group based on age, and mi-grant domestic workers, who represent a socially vulnerable group based on culture. We identify the importance of considering caregivers’ needs through an inclusive approach. Evidence-based practices of inclusive play-spaces are reviewed and analysed to provide insights into inclusive play. We propose design directions that both safeguard children’s right to play and address the needs of their caregivers.
