HPMS 汇集了关于公路路网规模、使用情况、状况及性能的数据。该系统由一个具备地理空间功能的数据库构成，用于生成报告并提供数据分析工具。HPMS 数据被美国交通部（U.S. DOT）、行政机构、国会以及交通运输界众多利益相关方所使用。

HPMS compiles data on highway network extent, use, condition, and performance. The system consists of a geospatially-enabled database that is used to generate reports and provides tools for data analysis. Information from HPMS is used by many stakeholders across the US DOT, the Administration, Congress, and the transportation community.
