A standardized regulatory impact assessment conducted by Caltrans.
California, United States
Summary Information
In California, regulatory changes in 2016 supported a transition from the Title 21 (T21) hard-cased electronic toll collection (ETC) protocol commonly used across the United States, to a newer and cheaper transponder sticker technology identified in ISO Standard 18000-63, also known as the 6C protocol.
Although toll agencies were initially expected to incur additional costs to purchase 6C transponders and related equipment, retrofit ETC systems, and dispose of old equipment, these costs were found to be minimal when compared to the overall savings and benefits of using the new system, and realized savings from the transition were anticipated within one year.
The baseline scenario for the economic analysis is highlighted below:
