The Purpose of the HPMS software is to provide data that reflects the extent, condition, performance, use, and operating characteristics of the Nation's highways. This data is used to asses the highway system performance under the Federal Highway Administration strategic planning process and for apportioning Federal-aid funds to all states. In addition, the HPMS serves the needs of the States, Metropolitan Organizations and local governments in assessing the highway condition, performance, air quality trends, and future investment requirements.
