TransCore Facilitates Nationwide Toll Interoperability

TransCore, a leader in comprehensive tolling solutions, announced today the publication of the Super eGo® (SeGo) protocol specifications to simplify the adoption of multi-protocol readers and transponders.  The specifications are available without restrictions at

“As agencies advance national interoperability, we are reiterating that the SeGo protocol is an open technology and we remain committed to facilitating this transition,” said TransCore President Tracy Marks.  “Because multi-protocol technology already exists and has been in operation for over 20 years, we believe this solution is the least disruptive for the traveling public and significantly reduces agency costs in attaining national interoperability.”

Nearly 45 percent of customers who access toll roads today use a transponder with the SeGo protocol.    By adding the SeGo technology to multi-protocol readers where it is currently not supported, these customers will be able to travel seamlessly across the country.  This protocol integration model can be replicated in other areas so 100 percent of customers can rapidly access all U.S. toll roads with one transponder.

“Regional toll interoperability is already being successfully achieved by enhancing our systems to incorporate the protocols in use by toll agencies across the U.S.,” said James Hofmann, Assistant Executive Director of Operations, North Texas Tollway Authority.  “The use of multi-protocol readers will ultimately help expedite the goal of nationwide interoperability by providing customers the ability to travel seamlessly across various toll systems without the need to change transponders or open new accounts.”
