May 2019 Luncheon: National Toll Interoperability

By Steve Crouch, P.E. | T&DI Secretary

The Transportation & Development Institute (T&DI) held its first 2019 Lunch Program on May 7 at the University Club at UCI with speakers from the Transportation Corridor Agency (TCA). Rick Carrier, TCA’s Director of Tolling and Customer Information Systems, introduced us to the “New Era of Tolling”, in which 6C tolling technology will allow to us to replace those bulky transponders with “stickers.” Samuel Johnson, TCA’s Chief Toll Operations Officer, discussed the ability to achieve interoperability through this 6C tolling technology. Using this technology, drivers throughout the western states will be able to use the same tolling devices for 33 facilities in 6 states. Thank you to our lunch sponsor WKE. As the event was well attended, it was a great kick-off for the re-start of the T&DI.

From L to R: Adrian Anderson, Steve Crouch, Juliet Su, Samuel Johnson, Kelsie Anderson, Rick Carrier,  Matt Dennerline, Alahesh Thurairajah, Alan Su, and Clint Isa.
