State Highway Reliability Report - Georgia
In the line graphs below, FHWA has shifted the "Year" label in the x-axis back by one year, from Data Reporting Year to Data Collection Year. More information
The information displayed is provided by the State in their 2018 Baseline Performance Period Report (BPP) and has not been edited by FHWA. Any questions about individual State reports should be directed to the respective State DOT
Please note: FHWA posted baseline data from State BPP reports to help bring context to their performance targets. This data may result in some discrepancies among published DOT performance data due to data sources and reporting years used when establishing the performance targets.

Basis for Non-Interstate National Highway System (NHS) Reliable Person-Miles Traveled:
This target was based on a review of the Highway Performance Monitoring System (HPMS) data with a comparison to current and historical funding levels. Historically, Georgia DOT (GDOT) has used its Computerized Pavement Condition Evaluation System (CoPACES) to perform pavement condition assessment. CoPACES is an annual visual inspection that identifies pavement distresses that the Department has used successfully for over thirty (30) years. The CoPACES inspection assists with route selection for rehabilitation and preservation treatments, and is performed on a sample of the network.
In 2018, GDOT moved to a fully automated process with 3D detection and evaluation. This process will not only provide a comprehensive analysis of the Department’s network, but will also accomplish this work much more safely, as the visual inspection required by the legacy CoPACES will no longer be necessary. The data collected by this automated system includes additional information, such as transverse profile, rutting, faulting, cracking, and International Roughness Index (IRI). It is expected that pavement scores will change with the move to automated data collection.
A conservative target was selected to account for this variability in pavement scores, for predicted trends in the network with current funding, and for the uncertainty in the current TAMP process and how it might be managed by FHWA.
