1. Objective

ㅇ To apply environmental impact reduction technology and develop noise map technology for low noise railroad implemention.

2. Contents and Range

ㅇ To develop railroad noise map considered the human auditory sense.

ㅇ To research break noise reduction method and curve section skill noise of rail cars.

ㅇ To develop optimization/commercialization techlonogy as a measurement of turnel micro pressure wave reduction.

ㅇ To develop technology to maintain and advance pollution treatment in the land around the railroad.

3. Result

ㅇ To develop a sound source/analysis module of a program that makes noise map considered human auditory sense.

ㅇ To secure high speed railroad brake noise reduction technology and suggest a curve part skill noise reduction measurement.

ㅇ To develop practical technology of tunnel exit/enterance/inner structure for tunnel micro pressure wave reduction in highway.

ㅇ To establish eco-friendly low-cost railroad pollution maintenance basis based on economics/environmental evaluation and to secure applicability through advancing polluted source treating technology in land of railroad.
