Transportation Performance Management

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 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.

  Using the monthly interstate reliability measures from January 2016 to December 2017, a linear trend line analysis was conducted. Adopting a conservative approach, the lower end of the projected 2-year and 4-year range is selected as targets for this measure.

  A detailed report was prepared by Georgia Department of Transportation (GDOT) that provides an overview of the “National Performance Management Measures for Assessing Performance of the National Highway System, Freight Movement on the Interstate System, and Congestion Mitigation and Air Quality Improvement Program (CMAQ) Final Rule”, the methodology to calculate the measures included in the rule, target setting process as well as the recommended 2 and 4-year performance targets.

  Using the monthly interstate reliability measures from January 2018 to December 2019, the 2-year condition was compared to the 2-year target. The 2-year condition at 80.8% is higher than the 2-year target at 73.0%, which demonstrates that the target is being met.

  N/A

  GDOT is making major investments in the State’s transportation network to deliver projects that will meet a community need and deliver positive benefits to drivers. Major Mobility Investment Program (MMIP) projects were pinpointed that will create additional capacity, improve freight movement, provide transportation improvements and efficiencies, enhance safety, and decrease travel times. The program includes Major Interchange Projects, Major Express Lanes Projects, Major Interstate Widening Projects, Commercial Vehicle Lane Project, and I-285 Advanced Improvement Projects. During the remainder of the performance period, GDOT plans to complete the State Route 400/Interstate-285 Interchange Construction project which will enhance the on/off ramps at this vital corridor, and will perform groundbreaking of the State Route 400 Express Lanes which will improve traffic flow to the north of Georgia, as well as introduce high-capacity transit in the Bus Rapid Transit system that will be jointly constructed with the project.

  N/A

  Georgia DOT plans to finish the widening of I-85 from I-985 to State Route 53 in 2020, while also completing the I-285/State Route 400 Interchange improvements in 2021. Additionally, the truck bottleneck at I-75/I-16 will see improvements as GDOT plans to complete Phase I improvements at this location in 2021. Additionally, GDOT will continue to fund its Regional Traffic Operations Program and Towing and Recovery Incentives Program to keep highway operations within the performance measures.

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).
