Arc Express was a project to build new rapid transit lines in île-de-France, France. It was designed to satisfy the need for increased travel among the suburbs of Paris and to relieve the saturation of a number of radial lines, such as Métro Line 13 and RER Line A. Previous proposals for an orbital metro line, dating back to the early 1980s, never came to fruition. Official studies of the Arc Express were launched by the president of Île-de-France region in December 2007.〔(20 Minutes : Feu vert pour le projet de rocade ferrée )〕 The project was superseded by the Grand Paris Express project. ==Projected Schedule== The projected schedule included the following steps over approximately ten years:〔(Site officiel d'Arc Express )〕 * December 2007: concept validation; * 2008 - 2009: preliminary studies; * Spring 2009: consultation with local officials; * July 2009: Referral to the National Commission on Public Debate (CNDP); * September 30, 2010 to January 31, 2011: public debate;〔(Communiqué des décisions de la CNDP du 2 juin 2010, § II - Débats décidés - Point 4 Projet Arc Express, p.3 )〕 * Early 2011: Decision on the implementation of the project; * Spring 2011: route plan; * 2011: Public inquiry; * 2012: Draft; * 2012-2019: Construction; * 2019: Public opening of the southern arc.〔"La durée des travaux (y compris déviation des réseaux concessionnaires) pour l’arc proche,serait donc de 6 ans, suivis de 6 mois d’essais et marche à blanc pour une mise en service 6 ans et demi après le début des travaux" (dossier des études STIF - Arc Express) http://www.debatpublic-arcexpress.org/docs/etudes/etudes-insertion-traces-setec-ingerop-xelis/3-arc-sud/3-0_memoire-specifique/memoire-arc-sud.pdf〕 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「Arc Express」の詳細全文を読む スポンサード リンク
