Managed lanes are char-acterized by the proactive implementation of operational strategies designed to respond to changing travel conditions. Managed lane strategies seek to optimize efficiency, per-formance and throughput by offering travel time savings and reliability through the applica-tion of vehicle occupancy and eligibility restrictions, pricing, and access control.
GDOT has taken a comprehensive approach to itsevaluation of managed lanes for Metro Atlanta. Througha multi-step analysis process, a range of alternativeshas been studied to determine the optimal solution for a

Managed lanes provide transporta-tion choice. Active management of these travel lanes results in guaran-teed travel times and reliability for users. Demand for additional gen-eral purpose lanes may eventually exceed capacity, but managed lanes can always provide a congestion-free alternative.
