HPMS_TDA

The FDOT GIS Highway Performance Monitoring System Roadways feature class provides spatial information on features used for the sample portion of the annual HPMS submittal to the Federal Highway Administration. The HPMSIDNO denotes the 12-digit number uniquely identifying the sample section. This number cannot be changed once assigned. Even if a roadway section that contains a sample is renumbered, the HPMS ID number will remain the same. Since when created, the HPMS ID uses the first eight digits of the roadway ID, the two numbers will no longer share those eight digits in common. This dataset is maintained by the Transportation Data & Analytics office (TDA). The source spatial data for this hosted feature layer was created on: 08/01/2026.
