The psychological, physiological, and material effects of ground vibrations induced from railroad were surveyed with the magnitudes of vibration sensing using questionnaire on residents living near railroad. These magnitude of vibration sensing and effects were compared as rate or percent total based on double distances from railraod. Also overall effects of railraod vibrations were compared with vibration levels measured or predicted. The about 70% of residents living within 40m from railroad sense railroad vibration, 15% of residents are influenced phychologically. But physilogical and material effects disappeared beyond 40m.
