FHWA Federal-Aid Divisions

The FHWA Federal-Aid Divisions dataset is as of February 05, 2025 from the Federal Highway Administration (FHWA) and is part of the U.S. Department of Transportation (USDOT)/Bureau of Transportation Statistics (BTS) National Transportation Atlas Database (NTAD). This dataset shows the geographic area of responsibility for each FHWA Federal-Aid Division Office. There is one of these offices in each U.S. State, therefore each area's boundary should match up with each state boundary. A data dictionary, or other source of attribute information, is accessible at https://doi.org/10.21949/1529301本FHWA联邦援助分区数据集（FHWA Federal-Aid Divisions dataset）的数据源为美国联邦公路管理局（Federal Highway Administration，FHWA），数据更新至2025年2月5日，隶属于美国运输部（U.S. Department of Transportation, USDOT）与运输统计局（Bureau of Transportation Statistics, BTS）的国家交通地图集数据库（National Transportation Atlas Database, NTAD）。本数据集用于展示各FHWA联邦援助分区办公室的地理责任辖区范围。美国各州均设有该类办公室，因此各分区的地理边界应与对应州的行政边界完全匹配。数据字典及其他属性信息可通过以下链接获取：https://doi.org/10.21949/1529301
