TRA Elevatization (, sometimes incorrectly spelled "elevatizion") is one of the methods used for Taiwan's "three-dimensional transport program", to solve the problem of railway lines dividing urban areas into pieces and causing traffic bottlenecks due to numerous ground-level crossings. The urban section of the original ground-level railway is elevated, or new sections of the tracks are built elevated from the start. Most of the railway treated this way is part of the national railway network in long-distance passenger or commuter rail rather than the urban rail transit system.〔A. Lu and A.N. Marsh. Zen and the Art of Commuter Rail Operations: Taiwan Railway Administration's Design, Operations, and Philosophy. http://amonline.trb.org/~searchResults?searchMode=advanced&searchParam-PaperNo=11-1301〕 Other three-dimensional transport programs in addition to the "elevated" include: underground railway, constructing new highway crossings above the railroad, the construction of an outer ring railway to bypass urban areas, establishing new train stations in urban fringes as well as a series of programs to solve the problem of urban railway separation. Taiwan Railways Administration operational routes for western Taiwan urban area, to barrierions of ground railway and influence on road traffic submitted improvement projects, by elevatization method, via Ministry of Transportation Railway Reconstruction Engineering Bureau (originally named "Ministry of Transportation Taipei urban area Underground Railway Engineering Bereau") and Taiwan Railway Administration (Only office Taoyuan Railway Elevatization) to office, part of engineering has been listed in New Ten Major Construction Projects of TRA MRTizion project. ==Shortcomings== * Elevated railway cannot be completely silent, vibration disturbing nearby residents is greater than that of the Mass Transit Railway (MTR), both must have sufficient clearance or soundproof walls to insulate from the noise. * The elevated railway technology can not effectively solve the integration of both sides of the development, only to reduce the gap. * Scenic issue for some citizens. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Taiwan Railways Administration Elevatizion」の詳細全文を読む スポンサード リンク
