The Purple Line, previously designated as the Bi-County Transitway, is a proposed 16-mile (25 km) transit line to link the Red, Green, and Orange lines of the Washington Metro transportation system in the Maryland suburbs of Washington, D.C.〔 The project is administered by the Maryland Transit Administration (MTA). On October 7, 2011 the proposed light rail line received Federal Transit Administration approval to enter the detailed engineering phase which, according to the ''Washington Post'', is "a significant step forward in its decades-long trek toward construction." ==History== The Purple Line was conceived as a rail line from New Carrollton to Silver Spring. Maryland's Glendening administration (which included John Porcari as Secretary of Transportation) removed the heavy rail option from planning discussion because it was felt that the cost was greater than the need. Robert Flanagan, the Maryland State Secretary of Transportation under Governor Robert Ehrlich, merged the Purple Line with another transportation project, Georgetown Branch Light Rail Transit (GBLRT). The GBLRT was proposed as a light rail transit line from Silver Spring westward, following the former Georgetown Branch of the Baltimore & Ohio Railroad (now a short CSX siding and the Capital Crescent Trail) to Bethesda. Both Governor Ehrlich and Secretary Flanagan introduced an alternative mode – bus rapid transit — that might have been utilized in lieu of light rail transit. To reflect this possibility, the administration changed the name of the project to the "Bi-County Transitway" in March 2003. Another reason that "the Purple Line" was discouraged by the Ehrlich administration was that its associations with the other color-oriented names of the Washington Metro system (which consists of heavy rail) might lead the public to expect a heavy rail option. The new name did not catch on, however, as several media outlets and most citizens continued to refer to the project as the Purple Line. As a result, Governor Martin O'Malley and Secretary of Transportation John Porcari opted to revert to "Purple Line" in 2007. In January 2008, the O'Malley administration allocated $100 million within a six-year capital budget to complete design documents for state approval and funding of the Purple Line. In May 2008, it was reported that the Purple Line could carry about 68,000 daily trips. A draft environmental impact study was issued on October 20, 2008. On December 22, 2008, Montgomery County planners endorsed building a light rail line rather than a bus line. On January 15, 2009, the county planning board also endorsed the light rail option, and County Executive Isiah Leggett has also expressed support. On October 21, 2009, members of the National Capital Region Transportation Planning Board voted unanimously to approve the Purple Line light rail project for inclusion into the region’s Constrained Long-Range Transportation Plan. Even though the project is overseen by the Maryland Transit Administration (MTA), it is not yet clear who would operate the Purple Line if it were constructed. MTA representative Michael Madden said that the Washington Metropolitan Area Transit Authority (WMATA) has been working with the MTA to develop the Purple Line. The future transit system could be operated by the state of Maryland, by WMATA, or by Montgomery and Prince George's counties. Regardless, planners intend to utilize existing Metrorail stations and for the Purple Line to accept WMATA's SmarTrip farecard. Metro's 2008 annual report asks readers to imagine that in 2030 the Purple Line will be integrated with WMATA's existing transit system.〔(【引用サイトリンク】title=2008 Annual Report )〕 Governor Larry Hogan, who opposed the project while campaigning in 2014, approved the Purple Line in June 2015, but cancelled its sister project, the Baltimore Red Line, citing excessive costs. Hogan reduced the state's contribution to the project from $700 million to $168 million, with the savings reallocated towards increased highway construction. The budget shortfall is expected to be covered by increased funds from Prince George's and Montgomery counties, as well as lower operational costs due to longer headways. 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「Purple Line (Maryland)」の詳細全文を読む スポンサード リンク
