Abstract: This study selected the bicycle path of the Taiyuan Riverside Greenway as a case study. Using questionnaire data covering four dimensions—acoustic environment satisfaction, sound source perception, soundscape affective quality assessment, and visual evaluation—we examined differences in soundscape evaluation and their underlying mechanisms between cycling and resting behaviors. Key findings revealed: (1) Significant differences in acoustic environment satisfaction between cycling and resting scenarios; (2) Marked variations in the perceived intensity of wind, conversation, and footsteps among sound sources; (3) Minimal differences in soundscape affective qualities and visual evaluations; (4) Correlation analysis showed that, in cycling contexts, acoustic satisfaction was collectively influenced by soundscape perception (i.e., sound source identification and affective assessment) and visual evaluation, whereas in resting contexts, soundscape perception was the dominant factor and visual evaluation exerted negligible influence. This study addresses the neglect of behavioral differences among urban greenway users and proposes a “dynamic–static zoned design” strategy to optimize ecological and experiential environments. The findings provide empirical evidence for soundscape design in high-density urban greenways.
