The Highway Performance Monitoring System (HPMS) provides data that reflects the extent, use, condition, and performance of the public roads in the United States. It consists of the All Road Network of Linear Referenced Data (ARNOLD) and Section Data which is the attribution. ARNOLD and Sections are linked though linear referencing. This data is analytical for the purpose of supporting transportation program, 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.</div></div>
