Human–environment interactions, a classic topic in geography, suggest that individuals and their environments might shape each other. Yet the specific mechanisms underlying these interactions regarding human personality traits have not been explored. This study examines the associations between human Big Five personality traits and built environment characteristics derived from street view imagery across four cities in Texas, United States, providing a descriptive foundation for understanding these complex human–environment dynamics. By integrating fine-resolution self-reported personality assessments with computer vision analysis of urban environments, we identified significant spatial clustering of personality traits at the ZIP code level. Our regression analyses reveal that built environment features and socioeconomic characteristics explain substantial variance in personality distributions, with Openness showing the strongest model fit (R2 = 0.47), followed by Agreeableness, Conscientiousness, Extraversion, and Neuroticism. Grouped built environment categories, socioeconomic factors, and demographic composition showed trait-specific patterns of association. These findings illustrate how personality traits could be associated with physical spaces at a smaller geographic scale than previously examined. Our results provide empirical evidence for understanding the link between psychological characteristics and environmental features, which can potentially enrich geography studies from a human-centered perspective.

Urban streets constitute essential everyday health infrastructure within the outdoor built environment, yet their potential to support physical activity remains unevenly realized. Current assessments prioritize formal sports facilities or rely on coarse, area-level metrics, leaving street-level differences in exercise supportiveness less visible. To address this gap, this study develops a theory-informed analytical framework for examining modelled exercise-supportiveness deficits across street networks. We employ Henri Lefebvres spatial triad as an interpretive lens, conceptualizing urban space as a contradictory and co-productive unity of three interconnected dimensions: Conceived Space (representations of space), Perceived Space (spatial practice), and Lived Space (spaces of representation). Drawing on the research agenda of Critical Quantitative Geography, these dimensions provide a vocabulary for organizing evidence on planned form, visible street conditions, and everyday activity traces. SHAP is then used to examine how the resulting indicator groups are associated with exercise intensity. Using Shenzhen as a case study, the analysis shows that conceived-space indicators account for the largest share of grouped SHAP attribution, while perceived and lived indicators reveal important local low-supportiveness patterns across development contexts. Grouped SHAP attributions are then used to construct a seven-mode diagnostic typology that identifies which C/P/L readings are associated with lower modelled street-level exercise supportiveness. Furthermore, a bivariate spatial association analysis identifies clusters where high population density coincides with low recorded street-level exercise intensity, highlighting locations for closer planning assessment. The framework combines machine-learning attribution with spatial-theoretical interpretation to examine health-supportive everyday movement environments at the street-segment scale.

Amidst ongoing urbanisation, understanding how various urban elements contribute to stress reduction and well-being is increasingly crucial. However, existing research has prioritized natural elements, reinforcing a nature-urban dichotomy that overlooks the restorative potential of the built environment itself. This systematic review examines the restorative value of urban environments through quantitative studies from 2010 to 2024, exploring the effects on cognitive, affective, and physiological outcomes. Following the Synthesis Without Meta-analysis (SWiM) reporting guideline, it narratively synthesises findings from 50 quantitative human studies, identified through PRISMA-referenced screening of peer-reviewed articles that report associations between urban environmental characteristics and restorative outcomes. Results indicate urban spaces with integrated greenery are more often linked to higher perceived restorativeness and short-term psychological benefits than predominantly grey comparators. Several built environment characteristics, including architectural façade design, design quality, service facilities, and street-scale vegetation, were positively associated with restoration. Psycho-environmental characteristics (e.g., serenity, prospect, refuge) and person–place relationships further shape restorative experiences. Future research should focus more on various urban settings—high-density neighbourhoods, historical districts, and waterfronts—and compare similarities and differences in their restorative mechanisms. The review identifies emerging neuro-urbanism and big-data approaches as transformative tools; despite current methodological limitations, they radically expand the potential to clarify mechanisms and enhance generalisability. Based on the evidence extracted from the 50 studies, an evidence-informed, hypothesis-generating conceptual framework is proposed to map the observed associations between urban environment attributes, restorative value, and health and well-being. The framework organises current associational evidence and identifies testable pathways for future research rather than depicting confirmed causal chains.

Traffic accidents are a major global concern, highlighting the need for advanced traffic analysis and predictive techniques. The emergence of crowdsourced street view imagery (SVI) platforms has transformed public participation in collecting urban data, initiating the development of human-centered traffic analytics. This article investigates the relationship between visual urban understanding derived from Mapillary SVI and the frequency of urban traffic accidents. We analyzed SVI’s visual complexities using the Mask2Former image segmentation model and provided spatial reasoning of the urban objects (e.g., cars, buildings, trees) by estimating visual distances between those objects and the drivers using Dist-YOLOv5. These distances were encapsulated as edge weights, with urban objects and the drivers as nodes, creating human-centered graphs at each SVI location. We propose a framework that integrates a graph-based deep learning approach, GAT-LSTM, to capture the spatial-temporal dynamics of these urban objects for modeling traffic-accident frequency. Our results indicate that this model outperforms a traditional machine learning method by over 70 percent in mean absolute percentage error (MAPE) and demonstrates superior performance compared to other deep learning-based methods. Additionally, we introduce a two-step Explainable AI (XAI) method to identify key factors associated with roads with higher traffic accident rates, thereby improving the interpretability and practicality of our research for understanding the urban safety environment.
