This study aims to investigate the neurocognitive status of people with different moods (depressed and non-depressed) both in a typical urban environment (TUE) and in an urban green environment (UGE).

The study was conducted with the participation of 210 individuals in a real environment. Heart rates of the participants were measured together with EEG and eye-tracking measurements while they were walking in a real urban environment (TUE and UGE). The participants were divided into depressed and non-depressed groups according to different moods. Movements within the city based on these two distinctions and different cognitive moods were investigated, together with the effects of the city plan on these people.

As a result, the green urban fabric was found to have a positive effect even on people with depression. Yet, it was found that the non-depressed group also spent more time in a green urban environment.

The study shows that urban planners and designers should assume an important role in the design of green spaces, which have a more intense visual and cognitive impact than structures.

This study intends to analyze the trend of walkability research over two years (2021–2022) in several aspects, including the research problem, gap and aim underlying walkability issues, research setting, the scale of analysis, the type of data, the data collection tool, the analysis method and contribution.

Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) is employed to conduct a systematic literature review from three leading databases including Web of Science (WoS), Scopus and Sage.

From the review, it can be concluded that the research focuses on two aspects, namely, the built environment and people. The studies in this field are conducted at different scales of the built environment, from macroscale to microscale, including region, city, neighborhood and street-level studies that are conducted around the world including Asia, Europe and America which receive high attention from researchers. Meanwhile, the study of walkability in Australia and Africa gains less attention. It is revealed that there are four factors of walkability including land use and accessibility for macroscale which cover region, city and neighborhood, while street network and pedestrian infrastructure and facility are mainly analyzed for street-level. Most of the studies widely utilize a quantitative approach for analyzing physical walkability factors in a measurement-based approach by using certain tools/software, and a perception-based approach by using questionnaires.

The findings can assist to keep up with the rapid pace of scientific publications and help accelerate the understanding of particular ideas in the field of walkability for the planning and design practice and policy that can be used by researchers/academia, urban designers, urban planners, architects, engineers and policymakers. Also, this study hopefully could assist further research direction for the future and could add value to a more advanced way of understanding the research on walkability.

This research provides a robust framework for walkability trend analysis and a comprehensive understanding of the main ideas from the existing research on walkability worldwide.

Urban mobility has substantially evolved in several western countries, shifting from interest in road expansion strategies to cater motorized movement to the emphasis on sustainable mobility. This is, however, not the case in several developing countries that still try to accommodate vehicular flows in inner historic cities. This paper aims at providing an assessment framework that helps in evaluating the effect of streetscape development on the walking and cycling environment in historic contexts.

This research follows a two-phase methodology. Phase 1 is the investigation of the literature review including the streetscape design, Sustainable Development Goals (SDGs) and indicators for the assessment of walking and cycling environment. This phase results in developing a set of indicators for the assessment. Phase 2 is the case study including, methods, steps and results of the assessment based on the output of Phase 1. This phase concludes with a discussion on the challenges and recommendations for the enhancement.

The streetscape development in Afrang was insufficient and negatively affected the walking and cycling environment. It was motorized-oriented, instead of enhancing green mobility. The interventions led to more crowds, safety risks and less pleasant experience. Moreover, the car users' experience was enhanced initially; however, the traffic situation did not persist. A sustainable urban mobility approach is necessary to be implemented with consideration to the global level and the relation to SDGs.

There is a gap in tackling the research problem both within the context of Port Said in particular and Egyptian context in general. Local authorities need a clear structured methodology to follow in the development of the streetscape. The assessment indicators gathered can be the basis for evaluating future plans.

This paper aims to determine the significance of tourist walkability on three community-based tourism sustainability indicators, namely, the economic, social and environmental benefits and costs impacting community’s quality of life through the lens of the triple bottom line approach with the institutional theory.

This study views institutions as either enabling or restricting the sustainable community-based tourism because institutions influence resource integration and value assessment by the beneficiary. Moreover, institutions also lead the co-creation of sustainable community-based tourism among various stakeholders. Drawing on this conceptualisation, the notion of sustainable community-based tourism is filtered through the lens of institutional theory. Thus, this work approaches sustainable community-based tourism as a dynamic process of co-creating a tourist destination formed by different actors’ and institutions within the ecosystem of the tourist destination. Meanwhile, the triple bottom line benefits and costs experienced by the overall community would produce net effects on the residents’ perceptions of sustainable tourism.

This paper classifies both tangible and intangible costs and benefits because of tourist walkability and its triple bottom line trade-offs experienced by tourists and residents. This paper penetrates new grounds by reviewing the triple bottom line impacts of tourist walkability on residents’ quality of life. Government policies as mediating variable and national culture and individual personalities of tourists and residents as moderating variables were discussed. A conceptual framework named Tourist Walkability Sustainable Tourism Impact on Residents (TWSTIR) is proposed. Finally, a Sustainable Community-based Tourism Strategic (SCBTS) model which is based on the two dimensions of intensity of tourist walkability and residents’ quality of life is proposed.

Research limitations may include a lack of assessment on political, technological and legal issues, and therefore, future research is warranted in these three areas. Some emotions and attitudes of the residents may not be captured since the Gross National Index (Gross National Happiness) may have its inherent blind spots.

This paper would be of interest to the scholarly world, as its original idea and concluding research agenda are burrowing into a new sub-field of tourism research. In view of growth and degrowth of sustaining community-based tourism, the SCBTS model is presented to provide directions for tourism policymakers and entrepreneurs to formulate and implement appropriate strategy for the tourist walkability activity per se and investment in the accompanying infrastructure.

This paper also presents the sacrifices and inequities in the communities and the relevance of government policies, national culture and individual personalities of tourists and residents, in which the attention of tourism policymakers and the communities that thrive on the travel and tourism industry should not be neglected.

The idea and discussion of this paper is original. This paper burrows into a new sub-field of tourism research. Tourist walkability needs more attention from the scholars, as this tourist activity can have positive and negative effects on residents’ quality of life. The TWSTIR framework is developed to discuss the relationships of tourist walkability, triple bottom line concept and residents’ quality of life within the sustainable community-based tourism scope. The SCBTS model is presented for tourism policymakers and entrepreneurs to perform appropriate strategy for the tourist walkability activity and investment in the accompanying infrastructure.

This study aims to investigate the relationships between the perceived neighborhood walkable environment (PNWE), neighborhood interaction (NI) and residents’ mental health, with a focus on examining differences among residents of different age groups.

Using an electronic survey questionnaire, data on PNWE, NI and mental health were collected from 1,159 residents across 205 communities in Shanghai, China. Our study utilized a structural equation modeling (SEM), employing the maximum likelihood estimation method. The structural equation model was fitted using the MPLUS software.

The mental health of young and middle-aged adults is generally poor, and they are at higher risk of depression than children and older adults. The effects of PNWE and NI on the mental health of residents varied among different age groups. As residents get older, their mental health is more affected by the PNWE. In addition, the influence of the PNWE on children and older adults’ mental health is direct and not mediated by NI. For young and middle-aged adults, the influence of the PNWE on their mental health needs to be mediated by NI.

This study marks the first examination of the relationship between PNWE, NI and mental health among different age groups of residents in China. The findings of this research can assist policymakers in gaining a deeper understanding of the underlying mechanisms by which PNWE affects mental health. Furthermore, it can contribute to the development of more targeted walkable environment designs aimed at enhancing mental health among various age groups.

An in-depth literature review was undertaken to uncover (1) what are described as the desired outcomes for 20 minute neighbourhoods (20MNs) – the normatively based ends which planners, architects and decision-makers want 20MNs to achieve; (2) the means (the mechanisms, levers, triggers and causal factors) that have to be correctly assembled and lined up for 20MNs to operate as intended and (3), in order to avoid naive environmental determinism, the behavioural changes required to support the operation of 20MNs even where the required configuration of means can be achieved. The content analysis was conducted following guidelines offered by the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) criteria.

Growing interest in the urban design concept of the “20MNs” has been greatly accelerated by the COVID-19 pandemic. It has been presented as a way of increasing the quality of local environments by enabling people to meet their daily needs through access to safe walking and cycling routes or by public transport. Internationally, it has captured the imagination of political decision-makers, built-environment practitioners and communities alike, as a life-affirming post-pandemic vision, held up as achieving environmental, health and economic improvements as well as reducing inequalities experienced by many. This paper's overall purpose is to separate the ends pursued in 20MNs from means available for achieving them.

The paper concludes that the ambition to see the 20MNs widely woven into existing urban, suburban and rural neighbourhoods will require significant effort to ensure all that all the component parts of, and key players in, planning's place-delivery systems are aligned and mutually supportive. Even where this can be achieved, further guidance will be needed on (1) how to operationalise the practical implementation of 20MNs and (2) how their success can be measured.

The originality of the paper lies in its efforts to discriminate between ends and means – between desired outcomes of 20MNs and the means available for achieving them. The significance of the paper lies here in this attempt to initiate a discussion on possible causal relationships between what is wanted and what would need to be done to achieve it. Without clarity about these relationships, misunderstanding, confusion and barriers to communication may arise across the many different organizations, stakeholder groups and actors involved. This lack of clarity could undermine trust and confidence, potentially undermining both the process and to its outcomes.

Many factors contribute to public rail transit use in an urban network. However, a dysfunctional relationship between the built environment and the transport system significantly deters such use. Architects, urban designers, town planners and policymakers must understand the factors that promote or deter pedestrian use of the urban environment.

The paper investigates four connectivity and walkability factors for three different metro stations in Doha, Qatar: Al Aziziyah, Hamad Hospital and West Bay. The analysis includes pedestrian sheds, block sizes, ground-level land uses and connectedness in the urban spatial network based on catchment contour maps using space syntax.

The results indicate the three metro stations and neighborhoods are representative of diverse type of neighborhoods in Doha: relatively compact but expansive for the Hamad Hospital Station area, metrically and topologically restrictive due to the poor planning and the peninsular location of the reclaimed land in the West Bay area, and expansive, shallow and reliant on attraction for the Al Waab transportation corridor associated with Al Aziziyah Station.

Time factors and temporary closure/capacity reductions due to the global pandemic restricted planned efforts to collect more pedestrian use data based on passive observations and preference choices using surveys during the study. Nonetheless, adapting the investigation to the circumstances produced significant findings.

The analysis can help us develop better guidelines and diagnostic tools to calibrate design and planning strategies promoting more walkable, healthy and sustainable neighborhoods.

The study is original due to examining stations of the new Doha Metro for the first time. However, it relies on well-established representational techniques in urban morphology and space syntax research.

To effectively combat the increasing rates of obesity, it is crucial to explore how environmental factors like sidewalk access impact weight-related outcomes. This study aimed to systematically examine the association between sidewalk accessibility and weight-related outcomes.

Databases were searched by keywords for relevant articles, which were published before March 3, 2024, to report the role of neighborhood sidewalk access on weight-related outcomes. The main findings of the selected articles were extracted from eligible studies by two independent reviewers.

A total of 20 out of 33 studies indicated a significant negative relationship between access to sidewalks and weight-related outcomes. Three studies demonstrated an indirect relationship between access to sidewalks and weight-related outcomes by greater access to physical environments. In addition, five studies reported no clear relationship, and three studies reported a significantly positive relationship between access to sidewalks and weight-related outcomes.

In general, people who live in urban areas with better sidewalk access benefit from better weight-related outcomes. Adults showed this correlation more prominently than adolescents and children. Therefore, sidewalks that have a positive effect on physical activity levels could be considered as a preventive measure against obesity.

One of the weight-related outcomes is obesity. Every community faces numerous challenges due to obesity, which adversely affects the quality of life and health. Environmental factors such as access to sidewalks could be associated with body weight due to lifestyle influences.

Fall accidents can cause casualties and economic losses in the construction industry. Fall portents, such as loss of balance (LOB) and sudden sways, can result in fatal, nonfatal or attempted fall accidents. All of them are worthy of studying to take measures to prevent future accidents. Detecting fall portents can proactively and comprehensively help managers assess the risk to workers as well as in the construction environment and further prevent fall accidents.

This study focused on the postures of workers and aimed to directly detect fall portents using a computer vision (CV)-based noncontact approach. Firstly, a joint coordinate matrix generated from a three-dimensional pose estimation model is employed, and then the matrix is preprocessed by principal component analysis, K-means and pre-experiments. Finally, a modified fusion K-nearest neighbor-based machine learning model is built to fuse information from the x, y and z axes and output the worker's pose status into three stages.

The proposed model can output the worker's pose status into three stages (steady–unsteady–fallen) and provide corresponding confidence probabilities for each category. Experiments conducted to evaluate the approach show that the model accuracy reaches 85.02% with threshold-based postprocessing. The proposed fall-portent detection approach can extract the fall risk of workers in the both pre- and post-event phases based on noncontact approach.

First, three-dimensional (3D) pose estimation needs sufficient information, which means it may not perform well when applied in complicated environments or when the shooting distance is extremely large. Second, solely focusing on fall-related factors may not be comprehensive enough. Future studies can incorporate the results of this research as an indicator into the risk assessment system to achieve a more comprehensive and accurate evaluation of worker and site risk.

The proposed machine learning model determines whether the worker is in a status of steady, unsteady or fallen using a CV-based approach. From the perspective of construction management, when detecting fall-related actions on construction sites, the noncontact approach based on CV has irreplaceable advantages of no interruption to workers and low cost. It can make use of the surveillance cameras on construction sites to recognize both preceding events and happened accidents. The detection of fall portents can help worker risk assessment and safety management.

Existing studies using sensor-based approaches are high-cost and invasive for construction workers, and others using CV-based approaches either oversimplify by binary classification of the non-entire fall process or indirectly achieve fall-portent detection. Instead, this study aims to detect fall portents directly by worker's posture and divide the entire fall process into three stages using a CV-based noncontact approach. It can help managers carry out more comprehensive risk assessment and develop preventive measures.
