From push to partnership: Evolving public engagement strategies in pandemic-induced street experiments
This study explores the evolution of public engagement strategies and their impact on pandemic-induced street experiments. Analysing 24 cases worldwide, it identifies three engagement structures: Push-Pull, Lean Push-Pull-Network, and Rich Push-Pull-Network. The first two structures revealed challenges, including public dissatisfaction with rapid, low-cost designs, limited governmental capacity to integrate feedback, and inadequate evaluation mec…
Measuring volumetric urban design: Compression, multi-level connectedness, and functional mix in transit-oriented developments in Hong Kong
High-density cities like Hong Kong are shaped by volumetric urban design, featuring three-dimensional pedestrian networks and integration of metro stations with property developments under transit-oriented development (TOD) principles. Conventional urban form metrics, which are largely two-dimensional, cannot capture these volumetric characteristics. This study addresses this limitation by developing quantitative metrics for three core elements o…
Dichloromethane extract from aerial parts of Ferula sinkiangensis prevents anhydrous ethanol-induced acute gastric ulcer by regulating PI3K-Akt/JNK/Nrf2 signaling pathway
The value-capture paradox of metro accessibility and gated communities in China
This paper highlights a critical challenge in China: although metro projects are justified by their potential to improve accessibility—a core public good—these benefits are often captured by private developers through the construction of gated communities around metro stations. We argue that local government’s reliance on land finance to cover the high costs of the infrastructure has distorted planning priorities, relegating the creation of perme…
Beyond temporary measures: How experiential learning in street experiments shapes urban mobility transitions
Tactical urbanism aims to rapidly transform urban environments through iterative experimentation. However, we know little about how learning shapes the long-term effectiveness and transformative potential of these interventions. This paper examines the role of local government implementers’ learning in sustaining tactical urbanism practices, specifically through the lens of street experiments implemented during the COVID-19 pandemic. Using experi…
Gendered impacts of public transport on social isolation and loneliness among older adults: Evidence from a natural experiment in Hong Kong
A well-designed public transport system has the potential to support social participation and alleviate social isolation and loneliness among older adults. However, limited research has explored whether such benefits differ between older men and women. Using a natural experiment involving a new metro line in Hong Kong, our cohort study (N = 449) of older people yields a surprising finding: contrary to previous studies suggesting that women are mo…
Ambiguity in state-owned land property rights increases transaction costs in China’s transit-oriented development projects
This paper provides compelling evidence that the ambiguity in state-owned land property rights increases transaction costs in China’s transit-oriented development (TOD) projects. The constitution defines the state as the de jure (legally defined) owner of urban land, but tiers of local government share the de facto (practically controlled) land property rights; this ambiguity complicates land use right transfer for TOD. Through expert interviews,…
From 3D pedestrian networks to wheelable networks: An automatic wheelability assessment method for high-density urban areas using contrastive deep learning of smartphone point clouds
Global Street Experiment: A Geospatial Database of Pandemic-induced Street Transitions
Street experiment is a tactical urbanism practice that involves implementing temporary changes in street use through regulatory or physical interventions, aimed at people-centric street transition. During the Covid-19 pandemic, cities worldwide implemented street experiments to accommodate the need for socially-distanced physical and commercial activities. However, we know little about the locations and urban environments of these pandemic-induce…

Does subjective wellbeing modify travel behaviour changes among older people in response to a new metro line
New metro and housing price and rent premiums: A natural experiment in China
Causal evidence of housing premiums of new metro lines is indispensable for financing and governing infrastructure investments. Previous studies have investigated the housing effects of urban rail transit with varying methods, while causality remains unsettled. This study used a natural experiment to estimate the causal effects of the new metro interventions on housing premiums in Shenzhen, China. We used metro planning knowledge, reasoning on pu…
Natural experiments in healthy cities research: How can urban planning and design knowledge reinforce the causal inference
Healthy cities researchers often ask questions about cause and effect: the causes are built environment interventions via urban planning and design practices, such as park renovation, a new bus line or a housing redevelopment programme; effects are individual and public health outcomes. The growing interest in natural experiments for causal inference in healthy cities research comes mainly from the public health fields. Planning and design knowle…

Decline in older adults’ daily mobility during the Covid-19 pandemic: The role of individual and built environment factors
Background Extensive research has shown that the COVID-19 pandemic dramatically impacted the daily mobility of older adults. However, very little attention has been paid to the role of individual and built environmental factors in decline in older adults’ daily mobility during the pandemic. Methods Based on a cohort survey of 741 older adults in Hong Kong, we conducted a one-way ANOVA to explore the differences in determinants (individual or envi…

Does China-Pakistan Economic Corridor improve connectivity in Pakistan? A protocol assessing the planned transport network infrastructure
Connecting the city: A three-dimensional pedestrian network of Hong Kong
The purpose of the paper is to investigate how a three-dimensional pedestrian network reshapes connectivity and helps to integrate the built environment of high-density cities. Using the case of Hong Kong, first, we elaborate how a continuous three-dimensional network constitutes an entirely different urban morphological spatial hierarchy compared to two-dimensional because of the footbridge system, underground connected with metro stations, and …
Walkability scoring: Why and how does a three-dimensional pedestrian network matter
Previous walkability scoring systems are all based on road networks, even though roads are not designed for pedestrians. To calculate an accurate walking score, we need pedestrian network data. This is especially the case in cities such as Hong Kong, where pedestrians are separated from vehicles by footbridges, underpasses or surface sidewalks. In this paper, we investigate why and how a three-dimensional pedestrian network makes a difference in …

Commuting Mode Choice in a High-Density City: Do Land-Use Density and Diversity Matter in Hong Kong
Hong Kong is a densely populated and transit-oriented Chinese city, which provides an ideal urban environment with which to study the various successful facets of land use policy as a model for potential replication to curb increasing car use in other Chinese cities. We examine the commuting mode choice of 203,900 households living in 4768 street blocks in Hong Kong from 2011 census. A street block is the smallest planning unit, made up of one or…

Associations between overhead-view and eye-level urban greenness and cycling behaviors
Ungating the city: A permeability perspective
China is seeking to prohibit the construction of any new gated communities and to gradually open existing schemes after three decades of growth of large-block gated estates. In this article, we use permeability analysis to explore the ‘what if?’ question posed by the policy: what if gated communities became permeable? We ask the question in respect of non-motorised access. We use two permeability metrics, closeness and betweenness, as outcome mea…

Understanding Walking Behavior among University Students Using Theory of Planned Behavior
Walking has been shown to improve physical and mental well-being, yet insufficient walking among university students has been increasingly reported. This study aimed to understand walking behavior of university students using theory of planned behavior (TPB). We recruited 169 undergraduate students by university mass email of the Chinese University of Hong Kong, and first administered a salient belief elicitation survey, which was used to design …
