Using de facto population data, we identify a sudden surge in crowd density near the incident site, revealing critical temporal vulnerabilities. In parallel, space syntax analysis uncovers spatial conditions characterized by high integration and low connectivity, features that constrained internal circulation and contributed to pedestrian entrapment. These findings indicate that the disaster stemmed not from temporal or spatial factors alone, but from their dangerous convergence within a structurally constrained environment. Furthermore, cluster analysis identifies other areas with similar spatial vulnerabilities, offering a tool for preventive screening. This study highlights the importance of integrating temporal crowd dynamics and spatial constraints into urban planning frameworks to enable proactive crowd safety strategies and the design of safer urban environments.</div></div>","PeriodicalId":48405,"journal":{"name":"Cities","volume":"168 ","pages":"Article 106418"},"PeriodicalIF":6.6,"publicationDate":"2025-09-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144996179","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, now that rationality no longer seems inherently constrained thanks to the advent of Artificial Intelligence, it seems reasonable to assume that decision-making processes themselves may undergo significant changes. Specifically, the research question that this article addresses is this: “What contribution can AI make to overcoming the limitations of certain methodologies used to support public decision-making in urban contexts?”.

We identified urban scaling laws for three key attributes—number of street junctions, gross domestic product (GDP), and population—across three spatial units: hotspots, non-hotspots, and the city as a whole.

This suggests that spatial disparities tends to be more pronounced in both smaller and larger cities in China. Furthermore, we applied scale-adjusted metropolitan indicators (SAMIs) to rank cities based on internal disparities, reinforcing our findings across different city groups.

While previous studies have highlighted the significant role of the built environment in shaping travel demand, research on its influences on intercity travel within urban agglomerations, particularly across different trip purposes, remains insufficient. To address this gap, this study proposes a data-driven methodology that includes trip purpose inference algorithm and explainable spatial deep learning model. Specifically, using mobile phone signaling data of the Beijing-Tianjin-Hebei Urban Agglomeration (BTH<img>UA) in China, we develop a rule-based algorithm involving travel patterns to infer intercity trip purpose, the thresholds of which are determined through a traveler-based sampling validation method. Subsequently, the geographically weighted neural network (GWNN) method, which effectively captures spatial heterogeneity and nonlinear relationships, is employed to investigate the influences of the built environment on different types of intercity travel. The results indicate that the proposed quantifying model outperforms benchmark models. The average contribution of distance, transportation, and socioeconomic variables have a greater influence than land-use variables, and the nonlinear effects of these variables show significant differences across various trip purposes. Notably, the factor of distance to Beijing influencing travel varies by purpose: commuting travel exerts a positive influence up to 120 km, leisure travel up to 160 km, and business travel up to 175 km. These findings underscore the critical importance of spatial governance in urban agglomerations, offering practical insights for planners to better align land use strategies with differentiated intercity travel demands, thereby facilitating coordinated regional development and efficient resource allocation.</div></div>","PeriodicalId":48405,"journal":{"name":"Cities","volume":"168 ","pages":"Article 106404"},"PeriodicalIF":6.6,"publicationDate":"2025-09-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144926019","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Due to prolonged neglect in maintenance and management, these communities are susceptible to external stigmatization. However, existing research rarely examines the effect of stigma on housing prices in such neighborhoods. To address this gap, this study explores the influence of stigmatization on housing prices in old urban communities, with a particular emphasis on the mediating role of the neighborhood environment. Utilizing street view image data and deep learning methods, this study constructs six indicators of the neighborhood environment: greenness, openness, walkability, imaginability, enclosure, and complexity. Based on these indicators, a hedonic pricing model and a mediation effect model are developed to empirically examine the complex relationships among old communities, neighborhood environment, and housing prices. To address the potential limitations of linear models, a robustness check was conducted by using a Gradient Boosted Decision Tree (GBDT) model combined with SHAP analysis. The results indicate that a significant stigma effect exists in old communities, leading to an overall decline in housing prices by 11 %. Further analysis reveals that this stigma effect can be categorized into a direct effect of psychological labeling (−9.6 %) and an indirect effect mediated by environmental factors (−1.4 %). The non-linear model produced highly consistent results, with the indirect effect mediated by the neighborhood environment accounting for 16.7 % of the total effect. These findings highlight the dominant role of social perception over physical conditions in shaping housing prices. The study offers empirical support for stigma theory in urban housing markets and provides practical implications for neighborhood regeneration strategies.</div></div>","PeriodicalId":48405,"journal":{"name":"Cities","volume":"168 ","pages":"Article 106417"},"PeriodicalIF":6.6,"publicationDate":"2025-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144922295","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
