GDOT successfully automated its manual reporting system by harnessing and consolidating big data into corridor-wide performance measures, saving hundreds of hours of development time each month.
The public-facing Automated Traffic Signal Performance Measures (ATSPM) website and dashboard allows engineers and other users to track trends at the intersection, corridor, and programmatic level as well as visualize maintenance-related problems.

GEORGIA’S IMPROVED TSMO MATURITY DRIVES A SAFER AND MORE RELIABLE COMMUTE

Summary Information

In 2017, the Georgia Department of Transportation (GDOT) and its private sector partners consolidated high resolution data from over 6,500 signals and nearly 16,000 vehicle probe miles into corridor-wide performance measures. These performance measures highlight monthly and quarterly trends for each corridor. Some of the metrics currently available on the dashboard include pedestrian delay, approach volume, and arrivals on red.  

Working with private sector partners, GDOT developed its Connected Data Platform (CDP) to begin tying disparate data sources together. In its current version, the CDP overlays crash, WAZE, ITS device, and highway patrol data in a clear and user-friendly manner. The software is envisioned to bring in even more data sources, such as traffic signal analytics, road weather, and interstate operations data. 
 
The data analytics tools that were developed or enhanced by GDOT have been made freely available to all public and private sector engineers in the state. Additionally, code behind the dashboard remains opensource for other states to use. For example, the Utah and Virginia Departments of Transportation are already using the ATSPM.  
 
Findings

  • Insights provided through various aspects of the ATSPM website have contributed to improved transportation systems management and operations (TSMO) as well as safer and more reliable commutes for roadway users.
  • GDOT has improved its TSMO maturity since its original capability maturity self-assessment in late 2016. In particular, GDOT has moved from level 2 to level 3 for "Business Processes;" from level 3 to level 4 for "Systems and Technology;" and from level 2 to level 4 for "Performance Measurement."
