State Road &Tollway Authority: State of Georgia

Summary Information

By leveraging an internationally recognized ISO standard, partnering with other states as part of the 6C Toll Operators Coalition (6C TOC) and using the OmniAir Consortium for 6C equipment certification, the State Road &Tollway Authority (SRTA) in Georgia reduced deployment costs through transponder pricing competition and common equipment testing.


The adoption of the 6C protocol greatly reduced SRTA's roadside RFID reader costs. Transponder (windshield sticker) costs were reduced from $9.20 per unit to $0.78 per unit. This unit cost savings allowed SRTA to provide transponders at no cost to tollway customers and enabled the state to transition to All Electronic Tolling with strong customer support.

With multiple installation options (windshield, bumper mount and headlight/motorcycle) SRTA was able to better accommodate a variety of customer segments and support unique vehicle windshield designs. As of February 2017, the 6C protocol has been used on over 30 million toll transactions in Georgia, collecting approximately $44 million with over 400K transponders distributed.
