Key components and combinations affecting this quality are identified. A dataset of 5000 streetscape images was developed, each labeled with 50 survey responses and component data. The image-based model outperformed previous approaches using both image and non-image inputs. The components contributing to pleasantness–unpleasantness were identified through Shapley-Additive-exPlanation analysis. Results showed that green space, traffic elements, pedestrian amenities, and street materials impact visual quality with varying combination effects. This study advances urban evaluation by developing an automatic method to predict streetscape quality and analyze microscale components.

This study examines Jiangdong Village in Ruoergai County, Sichuan Province, using a human-centered dynamic accessibility measurement approach to assess the impact of high-altitude environments on evacuation efficiency through psychological-physiological data analysis. By analyzing evacuation data from 77 villagers, we constructed a multiple linear regression model (R<sup>2</sup> = 0.846), which revealed a significant positive correlation between age and evacuation time (regression coefficient 0.93, P = 0.006). Younger participants exhibited better physiological adaptability (mean heart rate 106.07 bpm at 50s), whereas older individuals showed a slower heart rate response (mean heart rate 74.14 bpm at 50s) and delayed recovery. Psychological stress was also significantly correlated with evacuation time (correlation coefficient 0.64, P < 0.001), with high-stress individuals evacuating in 229.33s on average, compared to 142.89s for low-stress participants. The findings indicate that psychological stress and heart rate dynamics are key factors influencing evacuation efficiency.
