Review Study on Method of Valuation Basis on Selction for Envioronment - Friendly Railway Alignment by AHP(Analytic Hierarchy Process)

환경 친화적인 철도 노선선정 정량화 기법 사례의 검토

The energy efficiency and environment-friendly aspect of the railway system would be superior to other on-land transportation systems. In a preliminary feasibility study stage, the energy efficiency and problems related with environment are usually not considered. Selection of optimal railway line is taken into consideration include of the purpose of railway, geographical features and facility of management. The railway Alignment which could be reasons of environmental problems are focused and studied in this paper. This study performed opinions of specialists, checking of industrial environment, analysis of bid guideline to select the optimal line and executed AHP method to make quality model and choose weight factors. The investment for railway systems could be encouraged by the considering of main environmental elements evaluated with the modified noise and vibration standard for environment-friendly railway construction.
