A traffic barricade〔(【引用サイトリンク】url=http://www.sourcesecurity.com/products-search-results/barricades.html )〕 is a type of barricade fitted with flashing lights and used to block excavations or road construction or other safety-related purposes. Formerly made of wood, or wood and steel, many now have structural members made wholly of plastic or composite materials. * The ''A-frame barricade'' or ''parade barricade'' resembles a sawhorse with a brightly painted top rail. * The ''Type I (or II) barricade'' also known as a ''waffle-board barricade'' resembles a sawhorse that can be folded flat. Type I indicates sheeting on top; Type II has sheeting on top and bottom. * The ''Type III barricade'' has multiple rails supported by two end posts with feet. One large multi-state company providing traffic barricade services was Houston-based, Highway Technologies, Inc., a US construction company that maintained offices in 33 cities.〔(Traffic-barrier company closes its doors day before Colfax Marathon ), 18 May 2013, ''Denver Post''.〕 It filed for bankruptcy in May 2013, laying off 740 of its 825 employees.〔(Construction supply company closes doors, lays off 740 ), 28 May 2013, ''Houston Chronicle''.〕 The company was founded in approximately 1983.〔(Highway Technologies Lays off 180 Employees ), KDAF Dallas nightcap, 29 May 2013.〕 ==References== 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「traffic barricade」の詳細全文を読む スポンサード リンク
