Опубликована: Янв. 30, 2025

Despite the widespread use of street view imagery for Green View Index (GVI) analyses, variations in sampling methodologies across studies and potential impact these differences on results, including associated errors, remain largely unexplored. This study aims to investigate effectiveness various GVI calculation methods, with a focus analyzing point selection coverage angles results. Through systematic review extensive relevant literature, we synthesized six predominant methods: four-quadrant method, six-quadrant eighteen-quadrant panoramic fisheye method pedestrian method. We further evaluated strengths weaknesses each approach, along their applicability different research domains. In addition, address limitations existing methods specific contexts, developed novel technique based three 120° images experimentally validated its feasibility accuracy. The results demonstrate method’s high reliability, making it valuable tool acquiring images. Our findings that choice significantly influences calculations, underscoring necessity researchers select optimal approach context. To mitigate errors arising from initial angles, this introduces concept, “Green Circle”, which enhances precision calculations through meticulous segmentation observational particularly complex urban environments.

The Mechanism of Street Spatial Form on Thermal Comfort from Urban Morphology and Human-Centered Perspectives: A Study Based on Multi-Source Data

Buildings, Год журнала: 2024, Номер 14(10), С. 3253 - 3253

Опубликована: Окт. 14, 2024

The influence of street spatial form on thermal comfort from urban morphology and human-centered perspectives has been underexplored. This study, utilizing multi-source data focusing central districts, establishes a refined index system for prediction model based extreme gradient boosting (XGBoost) Shapley additive explanations (SHAP). results reveal the following: (1) Thermal levels display heterogeneity, with areas discomfort concentrated in commercial zones plaza spaces. (2) Compared to perspective, indicators correlate strongly comfort. (3) key factors influencing comfort, descending order importance, are distance green blue infrastructure (GBI), tree visibility factor (TVF), aspect ratio (H/W), orientation, functional diversity indices, sky view factor. All but TVF negatively correlates (4) In local analyses, primary affecting vary across streets different heat-risk levels. high streets, is mainly influenced by GBI, H/W, whereas low vegetation-related dominate. These findings provide new methodological approach optimizing environments both human perspectives, offering theoretical insights creating more comfortable cities.

How Urban Street Spatial Composition Affects Land Surface Temperature in Areas with Different Population Densities: A Case Study of Zhengzhou, China

Sustainability, Год журнала: 2024, Номер 16(22), С. 9938 - 9938

The arrangement and design of urban streets have a profound impact on the thermal conditions within cities, including mitigation excessive street land surface temperatures (LSTs). However, previous research has mainly addressed linear relationships between physical spatial elements LST. There been limited exploration potential nonlinear influence population density variations. This study explores multi-dimensional composition indicators obtained from street-view imagery applies generalized additive models (GAMs) geographically weighted regression (GWR) to evaluate indicators’ LST in areas with various densities. results indicate following: (1) six indicators—green space index (GSI), tree canopy (TCI), sky open (SOI), enclosure (SEI), road width (RWI), walking (SWI)—all significant effects summer daytime (2) Among all categories, GSI negatively affects Moreover, TCI’s shifts negative positive as its value increases. SOI SWI positively affect categories. SEI’s effect changes total high-population (HP) it remains low-population (LP) category. RWI category, LP HP (3) ranking is > SEI TCI RWI, being most factor. These findings provide key insights for mitigating LSTs through interventions, contributing sustainable development.
