TransCore releases SeGo protocol to accelerate USA’s nationwide toll interoperability


One of the leading developers of next-generation open road tolling (ORT) and traffic management systems, TransCore, has taken the next step toward the USA’s ambition of facilitating nationwide toll interoperability with the release of crucial software specifications.

TransCore has announced the publication of the Super eGo (SeGo) protocol specifications to simplify the adoption of multi-protocol readers and transponders across the USA. Nearly 45% of customers who currently access the country’s toll roads use a RFID (radio frequency identification) transponder with the SeGo protocol.

By adding the SeGo technology to multi-protocol readers where it is currently not supported, these customers will now be able to travel seamlessly across the country. This protocol integration model can be replicated in other areas so 100% of customers can rapidly access all US toll roads with one transponder.

“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’s 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.”

James Hofmann, assistant executive director of operations for the North Texas Tollway Authority, commented, “Regional toll interoperability is already being successfully achieved by enhancing our systems to incorporate the protocols in use by toll agencies across the USA.

“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.”
