The NIOP ( National Interoperability Program) to standardize toll facilities throughout the country began when Frank McCartney, then president of the International Bridge, Tunnel, and Turnpike Association (IBTTA), talked the US House Transportation Committee into committing the toll industry to delivering IOP and offering up the mid-2016 deadline that subsequently was written into federal law.
Three toll industry heavyweights the E-ZPass Interagency Group (IAG), the Alliance for Toll Interoperability and IBTTA have come together and have begun working toward the goal of national toll interoperability.
While the timeline for selecting and testing of a national protocol is progressing, IBTTA must also address back office technical approaches, marketing, and governance in order to support interoperability.
Ultimately, many issues still require resolution before NIOP can be adopted. We study the current status of the NIOP legislation (MAP21), discuss the role and activities of the major players, the technology issues and political inertia impacting the initiativeʼs progress.
