• Abstract:
  GDOT partnered with the Utah Department of Transportation to leverage their experience deploying ATSPM. GDOT's ATSPM deployment follows the same basic architecture used in Utah and features a public-facing website (https://traffic.dot.ga.gov/ATSPM/) to make data and analysis readily available. Data collected by the ATSPM system allows GDOT to better manage the operations and maintenance of signals. GDOT's traffic engineers can use data visualizations from the ATSPM system to answer questions like, are green times appropriate, or did a retiming project completed by a consultant team produce a benefit to the system. GDOT also uses ATSPM data when developing alternate routing plans for events and emergencies. For example, ATSPM tools helped to develop routing and adjust signal timing to address the 2017 I-85 bridge collapse in Atlanta.
