State Highway Reliability Report - Georgia

The information below summarizes the TPM Highway Reliability performance measures, which include two highway reliability measures and one truck travel time reliability measure. Per 23 CFR 490, State Departments of Transportation (DOTs) are required to establish 2- and 4-year targets for these measures. The targets should represent the anticipated condition/performance at the mid-point and end of the 4-year performance period. State DOTs establish targets at the beginning of each 4-year performance period, and report on progress every two years. When establishing targets, State DOTs have the flexibility to use the methodology they deem most appropriate. FHWA encourages States to review data sets and trends and consider factors that may affect targets. Performance targets should be data-driven, realistic, and attainable and should align with the performance management framework and legislative intent.

The targets and discussion of basis for targets, optional adjustment of targets, progress, and planned activities were provided by the State DOT in its most recent biennial performance report. FHWA has not edited this information. It is provided to help bring context to the State DOT's performance targets and progress. The data in the tables and graphs is from the biennial performance report or HPMS data submittal as noted below each measure summary. Any questions about the information should be directed to the State DOT.

Data reported by State DOTs was collected in the previous year, representing the condition/performance at the time of collection. Thus, in the tables and graphs below, FHWA labels data with the year representing the condition/performance, rather than the year the data was reported. The same thing is done for the targets--the year represents when the corresponding actual condition/performance data will be collected, not reported. More Information.

Significant Progress Determination
FHWA determines significant progress for these measures after the mid-point and end of each performance period. 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). As provided in 23 CFR 490.107(b)(2)(ii)(A), baseline condition/performance is derived from the latest data collected through the beginning date of the performance period. FHWA will classify the assessment of progress toward the achievement of an individual 2-year or 4-year target as “progress not determined” if a State provides the extenuating circumstance information required in 23 CFR 490.109(e)(5), and FHWA accepts the information.

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.

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.

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

This table shows FHWA’s most recent determination for the Infrastructure performance measures.

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 Significant Progress Determination Results table. 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.
