Study on the Influence of Urban Residential Street Space Environment on Population Stress Reduction: A Case Study of Tuanjiehu Street in Beijing

To explore the physiological and psychological effects of urban residential street space environments on stress recovery, this study takes Beijing Tuanjiehu Street as an example. Using the EAPRS environmental evaluation method, it identifies three key environmental features — green visibility rate, shading rate, and color richness, and then utilizes Kubios HRV and Photoshop for quantitative analysis. Physiological signals of subjects were measured in real time with wearable devices. Combined with subjective stress evaluations of sample streets, the study investigates the impact of residential urban street space on stress relief. Through quantitative analysis of indoor stress recovery perception experiments, the study obtains the potential factors that effectively relieved stress and the factors' relationships with street environment features. The results show that: 1) Green visibility rate, shading rate, and color richness are the environmental features that have a relatively significant impact on people's stress relief in residential urban streets. 2) The average heart rate is very significantly negatively correlated with green view rate, significantly negatively correlated with shading rate, and the diastolic blood pressure is very significantly negatively correlated with green view rate. 3) The Mean RR of heart rate variability is very significantly positively correlated with green view rate and significantly correlated with shading rate, and the SDNN of heart rate variability is significantly negatively correlated with color richness. 4) The scores of renewed PRS, including distance, extensiveness, attractiveness, and compatibility, are all significantly related to green view rate. 5) The higher the street shading rate, the higher the scores in the three aspects of distance, extensiveness, and compatibility, and the better the pressure relief benefits for residents; 6) The higher the richness of street colors, the higher the score for street attractiveness, and the higher the attraction of the street to residents. This study confirms that the street environment has an impact on the recovery of people's stress. Results are instructive for the design and construction of urban residential streets.
