Ground vibration is one of prime interests to geotechnical and geological engineering. The main concerns of ground vibrations involve annoyance, damage, disruption of vibration sensitive operations or activities triggering of landslides. Measurement and analysis of ground vibrations is a necessary procedure to determine their effect on structures and humans. The vibrations induced from traffic loads are real and complex but are least addressed. Traffic induced ground vibrations are a result of repetitive cyclic loading and needs screening for long term basis which need to be addressed in the design stage itself. This article aims to gain knowledge on ground vibrations induced by road and rail vehicles over silty soils. Field study is carried out using vibration sensors and data recorded is analyzed for vibration characteristics and its effect on soil properties. The factors affecting vibration intensity and vibration isolation properties of different materials are also studied in this paper. When the loads enter the infrastructure during vibration monitoring, it was observed that the vibration intensity increased irrespective of compressive strength of soil. Also, the distance from the source is also an important parameter. The trend shows that the attenuation of vibration was low with distance because low frequency vibrations are produced. High speed movement, heavy vehicles and rapid urbanization increases the vibration intensity and hence this research gain importance in the future.
