National Transportation Atlas Database (NTAD): Alternative Fuel Corridors 2021-Present [dataset]

The Alternative Fuel Corridors 2021-Present dataset is from the Federal Highway Administration (FHWA), and is part of the U.S. Department of Transportation (USDOT)/Bureau of Transportation Statistics’s (BTS's) National Transportation Atlas Database (NTAD). The dataset is a highway layer of corridors, primarily along the NHS, that are designated as Corridor Ready or Corridor Pending. It includes designations of five types of alternative fuels, Electric Vehicle Charging (EV), Compressed Natural Gas (CNG), Liquefied Natural Gas (LNG), Propane (LPG), and Hydrogen. Corridor-ready segments currently contain a sufficient number of fueling facilities to allow for corridor travel with the designated alternative fuel, and to qualify for highway signage. Corridors that do not have sufficient alternative fuel facilities to support alternative fuel vehicle travel are designated as corridor pending.

《2021年至今替代燃料走廊》数据集源自美国联邦公路管理局（Federal Highway Administration, FHWA），隶属于美国运输部（U.S. Department of Transportation, USDOT）/运输统计局（Bureau of Transportation Statistics, BTS）旗下的国家交通地图集数据库（National Transportation Atlas Database, NTAD）。该数据集为走廊类公路图层，主要沿美国国家公路系统（National Highway System, NHS）布设，被划分为「走廊就绪（Corridor Ready）」与「走廊待审（Corridor Pending）」两类。数据集涵盖五类替代燃料的标注信息，分别为电动汽车充电（Electric Vehicle Charging, EV）、压缩天然气（Compressed Natural Gas, CNG）、液化天然气（Liquefied Natural Gas, LNG）、丙烷（Propane, LPG）以及氢能。其中，标注为走廊就绪的路段已配备足够数量的配套加注设施，可满足对应替代燃料车辆的跨走廊通行需求，且符合公路标识布设的认证标准；尚未配备足够替代燃料加注设施以支撑替代燃料车辆通行的走廊，则被归类为走廊待审。
