Several studies have indicated that certain geometric factors have demonstrated a higher degree of effectiveness in cooling the surrounding environment. OTE studies often employ two commonly utilised factors, known as urban geometry indicating parameters (UGPs)—the sky view factor (SVF) and height-to-width ratio (H/W). This article compares OTE studies focusing on these two factors. The comparison encompasses characteristics such as study methods, places and times of conducting, and thermal indices. The findings indicate that geometric studies have primarily relied on simulation and field measurement methods. These studies were predominantly conducted in tropical or subtropical cities during warm seasons, with a preference for daytime investigations. Complex thermal indices, including the physiologically equivalent temperature and mean radiant temperature, were commonly employed. In addition to UGPs, other physical factors, such as orientation, were also taken into consideration. Studies on H/W and SVF differed slightly although they are both geometrically indicative.

Understanding the factors that contribute to flood vulnerability, allows us to develop effective initiatives that could mitigate the destructive consequences of flooding, while also protecting communities. The objective of this research is to identify and model the socio-economic and demographic factors that significantly influence flood vulnerability in the floodplains of Jackson, Mississippi, and Birmingham, Alabama, USA. First we analyzed the correlation between socio-economic and demographic factors then employed Principal Component Analysis (PCA) to address multicollinearity, a common challenge in multivariate statistical modeling. Subsequently, PCs-based global regression (PCR) and geographically weighted regression (PCGWR) analysis are used to identify key drivers of flood vulnerability. The findings demonstrate that a significant proportion of the variance (&gt;80%) of these factors can be captured by first two to three Principal Components (PCs). Consistent with existing research, African American, poverty, seniors, and the number of less educated people positively correlate with flood vulnerability, while income and housing prices exhibit a negative correlation. Additionally, PCGWR outperformed the Principal Component Regression (PCR) in most cases, highlighting the spatial heterogeneity of flood vulnerability. This study focuses on two U.S. cities, and the methodology is applicable to other cities with similar characteristics. The identified factors align with global research on flood vulnerability, making the proposed research and findings valuable worldwide. The findings of this research are useful for local governments, policymakers, and urban developers to make detailed location specific flood vulnerability plan to reduce impact of flood and improve urban resilience.</p></div>","PeriodicalId":45131,"journal":{"name":"Journal of Urban Management","volume":"13 3","pages":"Pages 437-455"},"PeriodicalIF":3.9,"publicationDate":"2024-06-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2226585624000694/pdfft?md5=0f30abadf191765a83c6257ba9ff88da&pid=1-s2.0-S2226585624000694-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142013081","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"社会学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, we used a mixed methods approach in which focus groups were used to explore users' perceptions of landscape attributes, their benefits, biodiversity, climate change, and conservation interventions in parks. This was followed by face-to-face interviews with the broader general public to quantitatively assess perceptions and acceptability for conservation interventions in parks. While plant density and functional diversity were identified as key landscape attributes, trade-offs may occur with other attributes such as multi-functionality and the order of the vegetation. Most conservation interventions had high acceptance levels, where the decrease of grass in parks was the most controversial attribute. All interventions were correlated with the importance of landscape attributes and climate change concerns, but poorly associated with knowledge of native biodiversity. The results support 1) increasing the functional diversity of plants in parks as a way to balance environmental and sociocultural benefits and promote the acceptability of conservation interventions, however such an increase should be linked to designs that respect notions of order and other park uses, and 2) environmental education based on climate change may be the key to improving acceptability of these initiatives.</p></div>","PeriodicalId":45131,"journal":{"name":"Journal of Urban Management","volume":"13 3","pages":"Pages 425-436"},"PeriodicalIF":3.9,"publicationDate":"2024-06-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2226585624000657/pdfft?md5=3db2af4b9dc6e4a97eba6da8d1539fb6&pid=1-s2.0-S2226585624000657-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141394921","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"社会学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Most prior work relies on non-standardized features such as road traffic forecasts or closed-source datasets to test predictions on a single route or network. We leverage standardized and open-source data from GTFS and GTFS-RT feeds to gather four months of realtime bus position data from Seattle and Trondheim's transit networks. We then test and refine strategies for generalizing model predictions across both locations. To achieve this, we first develop a data pipeline to process and clean the raw data, then extract features from the standardized sources. We then evaluate the performance of several deep learning and heuristic models in predicting bus travel times between source and target bus networks. Holdout data is taken from selected routes in the source city to validate the internal generalization of the models. Data from the target city is used to evaluate the external generalization of the models. An ablation study explores the impact of different open data sources on model generalization (GPS, static timetables, OpenStreetMap and other realtime trips). We then extend the analysis to 33 international bus networks, placing the results in broader context and testing fine-tuning strategies for generalization. Results show that deep learning methods generalize well within the source network, with as little as 1% loss in MAPE on holdout routes. With minimal fine-tuning generalization is significantly improved on the target network. Model features built on static schedule data, realtime positions or OpenStreetMap embeddings improved generalization performance (up to 10% reduction in MAPE). This was more pronounced for networks with a greater initial quantity of training data. As a route-planning tool for roadways without prior data, geospatial data mining can provide reasonable bus travel time estimates. For cross-sectional bus network analysis, fine tuning on at least 100 trajectory samples for each target network is required to significantly outperform baseline heuristics.
