Omnitrans巴士将超过100万英里处CNG英里的旅行，2013年4月

美国公共交通协会（APTA）报告，超过35％的美国公共运输车辆使用替代燃料或混合动力技术，2011年1月1日。这是一个鲜明的对比，使用替代燃料的汽车，在2010年的1.3％，根据能源情报署（EIA）的年度展望。操作上天然气的车辆都走在了前列。

“公共交通是环保高效的车辆，一路领先”，“亚太贸易协定”的总裁兼首席执行官Michael Melaniphy说。“公共交通车辆试验场的环保技术可能在某一天成为国家的汽车车队的一部分。”

“亚太贸易协定”的统计，2011年初显示，18.6％的美国公交车使用压缩天然气（CNG），液化天然气（LNG）和混合。近9％（8.8％）的公共交通巴士，混合动力车和生物柴油近8％（7.9％）的公共交通巴士使用。

“今天的现代公交车是越来越多的混合燃料是良好的环境是由”亚太贸易协定“，说：”主席花都卡斯蒂略。“公共交通行业是一个绿色产业和致力于改善环境。”

“亚太贸易协定”指出，美国使用公共交通每年节省37万吨的碳排放。此外，由于公共交通使用在美国每年可以节省470亿加仑的汽油，公共交通乘客做自己的一部分，以帮助我们的国家能源独立，根据“亚太贸易协定”。

下面列出的是CNG燃料车队在全国范围内小型，中型和大型系统的多样性的例子：

• 达拉斯，德克萨斯州 - DART的CNG新的舰队40英尺巴士车队开始服务2013年1月28到2015年将取代该机构的混合柴油和液化天然气公交车。2015年底，该机构的年度燃料成本将减少近三分之二。DART将每周五个新巴士投入服务，以取代现有的机队。
• 洛杉矶，加利福尼亚 - LA地铁经营2,200 CNG汽车在美国最大的CNG车队。洛杉矶地铁也买在美国的所有公交车的15％。
• 加利福尼亚州San Bernardino - Omnitrans所有CNG舰队将超过100万英里处，2013年4月。第一Omnitrans CNG公交车在1997年开始购买柴油，压缩天然气的过渡，并走在了前列，采用清洁燃料技术几年前区域的空气质量法规授权开关。
• 宾夕法尼亚州立学院 - 中心区交通管理局的整个舰队上运行的CNG。它是第一个在东海岸运输机构将其整个柴油车完全替代燃料运行。
• 亚利桑那州凤凰城 - 谷地铁站的巴士车队使用CNG和生物柴油燃料，以及电动混合动力公交车。
• 萨利姆，OR - 萨利姆-科泽尔运输的车队由34辆CNG公交车和30个生物柴油巴士。在2010年，过境区购买了第一气/电混合总线。

  Omnitrans buses will surpass the 100 million mile mark in CNG miles traveled, April 2013

  The American Public Transportation Association (APTA) reports more than 35 percent of U.S. public transportation buses use alternative fuels  or hybrid technology, as of January 1, 2011.  This is a striking contrast to the 1.3 percent of automobiles that used  alternative-fuels in 2010, according to the Energy Information Administration’s (EIA) Annual Outlook. Vehicles operating on natural gas are at the forefront.

  “Public  transportation is leading the way with environmentally efficient vehicles,” said APTA President and CEO Michael Melaniphy. “The public transit vehicle fleet is the proving ground for environmental technology that may some day become a part of the nation’s automobile fleet.”

  APTA statistics for early 2011 show that  18.6 percent of U.S. transit buses used compressed natural gas (CNG), liquefied natural gas (LNG) and blends.  Almost 9 percent (8.8%) of public transit buses were hybrids and nearly 8 percent (7.9%) of public transit buses used biodiesel.

  “Today’s modern public transit bus is increasingly either a hybrid or is powered by fuels that are good for the environment,” said APTA Chair Flora Castillo.  “The public transportation industry is a green industry and is committed to improving the environment.”

  APTA noted  that U.S. public transportation use saves 37 million metric tons of carbon emission every year.  Additionally, since public transit use in the United States saves 4.7 billion gallons of gasoline annually, public transit riders are doing their part to help our nation be energy independent, according to APTA.

  Listed below are examples of the diversity of CNG-fuelled bus fleets across the country in small, mid-sized, and large systems:

  • Dallas, TX – DART’s  new fleet of CNG 40-foot buses fleet began service on January 28, 2013 and will replace the agency’s mix of diesel and liquefied natural gas buses by 2015.  The agency’s annual fuel costs will be cut by nearly two-thirds by the end of 2015.  DART is putting five new buses into service every week to replace the existing fleet.
  • Los Angeles, CA – LA Metro operates the largest CNG fleet in the U.S. with 2,200 CNG vehicles.  LA Metro also buys 15% of all transit buses in the United States.
  • San Bernardino, CA – Omnitrans’ all CNG fleet will surpass the 100 million mile mark in April, 2013.  Omnitrans first started to purchase CNG buses in 1997 and was at the forefront of the transition from diesel fuel to compressed natural gas, adopting the clean fuel technology years before regional air quality regulations mandated the switch.
  • State College, PA – Centre Area Transportation Authority’s entire fleet runs on CNG.  It was the first transit agency on the East Coast to convert its entire diesel fleet to one that operates entirely on alternative fuel.
  • Phoenix, AZ – Valley Metro’s bus fleet uses CNG and biodiesel fuels, as well as electric-hybrid buses.
  • Salem, OR – Salem-Keizer Transit’s fleet is made up of 34 CNG buses and 30 biodiesel buses.  In 2010, the transit district purchased its first hybrid gas/electric bus.
