Highway Performance Monitoring System [HPMS]

Description / purpose

HPMS is a national highway information system that includes data on the extent, condition, performance, use, and operating characteristics of the Nation's highways. While every effort has been made to ensure accuracy and completeness of the data, users should carefully evaluate its accuracy, currency, completeness, and relevance for their purposes. In 2014, a Linear Referencing System (LRS), which links the HPMS attributes to geospatial data for all public roads, was created to meet the Federal Highway Administration (FHWA)’s All Road Network of Linear Referenced Data (ARNOLD) requirement. Caltrans monitors and collects GIS information about highways including traffic volumes, truck volume, bridges, HOV lanes, vistas, rest areas, bottlenecks, express lanes, park and ride lots, etc.
