Noise impact assessment of mass rapid transit systems in Delhi city

257-262Noise and vibration assessments are key elements of the environmental impact assessment studies of mass transit projects. Although the technological innovations associated with operation of mass rapid transit systems (MRTS) play a vital role in improving transport facility in Delhi city, yet to gain complete acceptability among the commuters, their operation should not cause additional noise and vibration problems in immediate vicinity. The present work reviews the international noise standards proposed for transit trains noise and investigates the noise impact assessment of elevated metro rail corridor in Delhi city. The cumulative accentuated ambient noise levels due to operation of elevated metro trains in areas based on their traffic density is analyzed
