Description
Abstract
The Federal Highway Administration (FHWA) has the responsibility to assure that adequate highway transportation information is available to support its functions and responsibilities, including those of the Administration and the Congress. The primary purpose of the Highway Performance Monitoring System (HPMS) is to serve these data and information needs. The HPMS provides data that reflects the extent, condition, performance, use, and operating characteristics of the nation's highways.
The HPMS by itself is not geospatial data. It is linked to another FHWA dataset, the National Highway Planning Network (NHPN), through linear referencing. The NHPN provides the geospatial component of this dataset.
Purpose
The HPMS provides data that reflects the extent, condition, performance, use, and operating characteristics of the nation's highways. It supports informed highway planning, policy making, and decision making at the national, state, and local levels.
