ABSTRACT: Managing vehicle speeds and ensuring road safety in residential neighborhoods have led to the widespread adoption of various traffic calming strategies, with speed humps being among the most implemented solutions. However, their implementation has raised significant concerns regarding secondary environmental impacts, particularly noise and vibration generation that can adversely affect residential communities during sensitive nighttime hours. This study addresses a critical gap in understanding the temporal dynamics of noise and vibration pollution induced by speed humps during nighttime periods in Japanese residential neighborhoods. Statistical analysis of LAeq measurements revealed significant temporal patterns: immediate increase (+2.71 dB, p p p
