Atlanta,Georgia,United States

Summary Information

Deteriorating performance of the high occupancy vehicle (HOV) lanes on I-85 during peak periods as a result of heavy usage provided the focus of the Atlanta congestion reduction demonstration projects. To address the performance problems, the following strategies were deployed:
  • Conversion of the existing HOV lane to high occupancy/toll (HOT) lanes, called Express Lanes on 16 miles of I-85 northeast of Atlanta
  • Addition of 12 new buses and 3 new bus routes
  • Four new or expanded park and ride facilities
  • Targeted outreach to increase the number of 3-person carpools from existing 2-person carpools and single-occupant vehicles
  • Deployment of innovative enforcement technologies on the Express Lanes
Evaluation of the deployments considered the period before and a period of one year after deployment.
