Transportation Performance Management

 

State Highway Infrastructure Report - Georgia

In the line graphs below, FHWA uses Data Collection Year instead of Data Reporting Year to represent snapshot condition/performance at the time the data was collected. More information

The information displayed is provided by the State Department of Transportation (DOT) in their 2018 Baseline Performance Report, 2019 Highway Performance Monitoring System (HPMS) data submittal, and 2020 Mid Performance Period (MPP) Progress Report and has not been edited by FHWA. Any questions about individual State reports should be directed to the respective State DOT.

Please note: FHWA has posted data from State DOT reports to help bring context to their performance targets. This data may result in some discrepancies among published State DOT performance data due to data sources and reporting years used when establishing the performance targets.

Significant Progress Determination

Using data from the 2020 MPP Progress Report, FHWA has determined whether a State DOT has made significant progress toward achieving its individual targets for five National Highway Performance Program (NHPP) measures and one National Highway Freight Program (NHFP) measure, as described in 23 CFR 490.109.

  • Interstate Pavement in Good Condition

    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.

    Georgia elected to set a target based on full distresses +IRI. The target was set at 40%. FHWA calculated value is 46.5%. Georgia has met and exceeded its target for this performance period. The target for the 4-year period is not being changed at this time. This conservative target is being used to account for the variability in pavement scores between the FHWA calculated values and Georgia's calculated values, predicted trends in pavement deterioration, and continued uncertainty in how the TAMP process is to be managed by FHWA.

    N/A
    Georgia DOT continues deployment of a 3D automated pavement evaluation process. The Department has also deployed a new pavement management system. The Department is using this system to help evaluate where to best prioritize its limited resources. The Department continues to fund the Capital Maintenance program at a level that should continue to meet this target.

    Target -- -- 50.0 -- 60.0

  • National Highway System (NHS) Bridges in Good Condition

    Currently the percent of bridge deck area in good condition is 47.3 percent. The Department has set a two-year target of 50 percent. This target was set using the current list of projects that will be let and completed by the end of the 2019 deadline.

    The Department has set a 4-year target of 60 percent. This target was set using projects that are currently being developed and what we envision the bridge management program to assist in developing. Factors affecting the achievement of this target include funding and accuracy of the bridge asset management program.

    Significant progress has been made with the completion of several preservation, rehabilitation, and replacement projects such that the Department has achieved and surpassed the 2-year target. The 2-year target was 50 percent of the bridges on the NHS would be classified as Good condition. The percent of NHS bridges classified as Good is 68.0 as of March 2020.

    N/A
    With the updated management system (AASHTOware - BrM), more accurate degradation curves and additional element data will enable the Department to provide a more accurate predication of which bridges might fall into the good and poor classifications moving forward. With this management system, the Department is more capable of developing a preservation, rehabilitation, and replacement program to maintain the 4-year target. The current target is still applicable to account for predicted trends in the network with current funding, to account for the uncertainty in moving to an updated data management system, and to account for the uncertainty in the current TAMP process and how it might be managed by FHWA.

  • National Highway System (NHS) Bridges in Poor Condition

    This target was based on a review of the National Bridge Inventory (NBI) condition data with a comparison to current and historical funding levels. Historically, Georgia DOT has used a data management system that stored only a limited amount of condition data and is no longer sufficient due to the recent updates of the federal requirements. The Department follows the Recording and Coding Guide for the Structural Inventory and Appraisal of the Nation’s Bridges federal bridge guidelines.

    With an updated management system, more accurate degradation curves will enable the Department to provide a more accurate target of which bridges might fall into the good and poor classifications. A conservative target was selected to account for predicted trends in the network with current funding, to account for the uncertainty in moving to an updated data management system, and to account for the uncertainty in the current TAMP process and how it might be managed by FHWA.

Significant Progress Determination

PLEASE NOTE: Each State’s performance target assessment is based on its own State-specific target methodology and program philosophy. Therefore, conclusions should not be drawn based only on the information in the 2020 Mid Performance Period Significant Progress Determination Results table. For example, the State may have set aggressive targets, and not met those targets, while another State may have set more easily attainable targets, and met those targets. FHWA understands that each State’s program is unique and therefore does not prescribe a methodology for States to set targets. States have the flexibility to use the methodology they deem most appropriate when setting their performance targets.

A State has met or made significant progress toward target achievement if “actual” condition/performance is equal to or better than the established two-year target or “actual” condition/performance is better than baseline performance 23 CFR 490.109 (e).
