Abstract

This study focuses on the impact of visual factors on the soundscape evaluation of urban trunk roads. On-site audio-visual assessments were conducted in thirty pedestrian spaces in Tianjin, and a structural equation model (SEM) was constructed to analyse the relationships between visual factors and soundscape evaluation. The results indicated that traffic noise dominates, followed by human and other sounds, with relatively little natural sound. Rated pleasantness low (−0.79) and eventfulness high (0.71). Sound environment assessment scored low (2.99). Correlation analysis revealed that except for sky visibility and street transparency, all visual factors in this study were positively correlated with pleasantness and sound environment assessment. Only greenery diversity was negatively correlated with eventfulness. The results of the SEM indicated that natural landscape, spatial environment, and street interface positively impacted pleasantness, with the spatial environment having the greatest impact (0.217). The research results provide a scientific basis for improving urban audio-visual environment.

期刊介绍： Transportation Research Part D: Transport and Environment focuses on original research exploring the environmental impacts of transportation, policy responses to these impacts, and their implications for transportation system design, planning, and management. The journal comprehensively covers the interaction between transportation and the environment, ranging from local effects on specific geographical areas to global implications such as natural resource depletion and atmospheric pollution. We welcome research papers across all transportation modes, including maritime, air, and land transportation, assessing their environmental impacts broadly. Papers addressing both mobile aspects and transportation infrastructure are considered. The journal prioritizes empirical findings and policy responses of regulatory, planning, technical, or fiscal nature. Articles are policy-driven, accessible, and applicable to readers from diverse disciplines, emphasizing relevance and practicality. We encourage interdisciplinary submissions and welcome contributions from economically developing and advanced countries alike, reflecting our international orientation.
