PM3 TARGET SETTING AND MID-PERFORMANCE PERIOD UPDATE

CLIENT: Georgia Department of Transportation

Purpose of Project

The Mid-Performance Period report builds on the Baseline Performance Period report, reflecting the actual 2-year performance measure results and reviewing the 4-year performance measure targets for continuation. This report captures the Georgia Department of Transportation’s (GDOT) response to changes in the performance measures in accordance with the requirements set by the U.S. Department of Transportation (USDOT) rules associated with the Fixing America’s Surface Transportation Act (FAST Act), as established by the Moving Ahead for Progress in the 21st Century Act (MAP-21).

The System Performance, Freight, and CMAQ (PM3) report evaluates six performance measures required for evaluation, which are as follows:

  • Percent of person-miles traveled on the Interstate that are reliable;

  • Percent of person-miles traveled on the non-Interstate National Highway System (NHS) that are reliable;

  • Truck Travel Time Reliability (TTTR) Index;

  • Annual Hours of Peak Hour Excessive Delay (PHED) Per Capita;

  • Percent of Non-Single Occupancy Vehicle (SOV) Travel; and 

  • CMAQ Emissions Reduction

Our Role on the Project

As part of the General Planning Support Services on-call contract, Modern Mobility Partners (MMP) lead the effort to retrieve the reliability values from the National Performance Management Research Data Set (NPMRDS) and calculate the reliability and PHED measures for the most recent two years of data, 2018 and 2019. Additionally, MMP lead the effort to calculate the SOV and CMAQ emissions reduction values using U.S. Census Bureau and CMAQ Public Access Database data, respectively.

Upon retrieving the data, MMP worked with GDOT to clean the datasets, identify outliers, and determine which 4-year targets, if any, would need to be updated to reflect the most recent data changes. Upon completion of the analysis, MMP prepared a report documenting the findings for the performance measures. Additionally, MMP prepared two reports for the CMAQ emissions reductions to cover the projects being undertaken by the Atlanta Regional Commission (ARC) (Atlanta Metropolitan Planning Organization (MPO)) and the Cartersville-Bartow MPO.
