BETA - Highway Performance Monitoring System (HPMS) 2023

The BETA release of the BETA - Highway Performance Monitoring System (HPMS) 2023 dataset was created using the most current data as of December 31, 2023 by 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). The data represents a snapshot of extent, usage, condition, and performance as of December 31, 2023. This file geodatabase download provides HPMS data for each state as an individual feature class. It consists of the All Road Network of Linear Referenced Data (ARNOLD) geometry and the Section Data which is the attribution. ARNOLD and Sections are linked though linear referencing and are part of the HPMS data program. These data are analytical for the purpose of supporting transportation programs, funding and policy decisions at a national level. Operational applications such as navigation and routing may take advantage of HPMS with the understanding that it represents the average and not “real-time” of the system. The Highway Performance Monitoring System Field Manual contains a detailed description of each data element including coding instructions and attribute definitions. The Field Manual is available at: https://doi.org/10.21949/1519108. A data dictionary, or other source of attribute information, is accessible at https://doi.org/10.21949/mrpb-7x82本数据集为公路性能监测系统（Highway Performance Monitoring System, HPMS）2023版测试版，由美国联邦公路管理局（Federal Highway Administration, FHWA）基于截至2023年12月31日的最新数据编制，隶属于美国交通部（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）。该数据集呈现了截至2023年12月31日的路网范围、使用情况、技术状况与运行性能快照。本次发布的文件地理数据库下载资源，将全美各州的HPMS数据封装为独立要素类。数据集包含线性参考数据全路网（All Road Network of Linear Referenced Data, ARNOLD）几何数据，以及作为属性信息的路段数据（Section Data）。ARNOLD与路段数据通过线性参考机制关联，二者均为HPMS数据项目的组成部分。此类数据属于分析型数据集，用于支撑国家级交通规划、经费分配与政策制定工作。导航、路径规划等业务应用可基于HPMS开展，但需注意该数据反映的是系统平均运行状态，而非实时数据。《公路性能监测系统现场手册》（Highway Performance Monitoring System Field Manual）对每个数据元素均有详细说明，涵盖编码规则与属性定义。该手册可通过以下链接获取：https://doi.org/10.21949/1519108。数据字典或其他属性信息来源可通过以下链接获取：https://doi.org/10.21949/mrpb-7x82
