HOV to HOT Conversion Impacts on Carpooling

The goal of this study is to better understand the impact of HOV/HOT conversions on carpools, and the potential implications for the successful implementation of regional managed lanes plans in Atlanta and other major metropolitan areas. The team will work with the Georgia Department of Transportation (GDOT) and the Georgia Department of Revenue to identify specific households that changed carpooling activity and invite these drivers by mail to participate in the mail-out/mail-back survey. The survey results will identify the most important factors affecting changes in carpooling activities in each demographic groups.
