Re: Issues With Automated Traffic
"6) If the system doesn't see the speed limit change because a tree limb blocked the camera(s), who pays the ticket?"
Why rely on optical imaging which is, lets be honest, buggy in all its forms. Either require the local planning agency to post the speed limits for road sections so that the onboard systems can update accordingly, or use RFID in speed sign gates as a direct instruction to the system.
Hell, to avoid someone playing stupid games like swapping speed signs around, do both. That way you inject a form of error correction into the whole thing.
