I'm going back to clause 15(b). It states, and I quote:
15.(b) respecting the tolls, fees and other charges that may be imposed by owners or operators of international bridges or tunnels for their use, to ensure the efficient flow of traffic;
As you said a bit earlier, the purpose of this paragraph is to ensure the efficient flow of traffic. Would it be possible for you to make a recommendation, or a requirement, that the toll collection system be modified to ensure more efficient traffic flow? In fact, there could be various collection methods, such as manual methods or more efficient methods, such as visual detection methods.
