I should have just searched on the internet. And, yes, some of the suggestions I find using a quick search include standing up straight, and waving your arms... I guess it's worth a try?

Quote:To maximize your probability of detection, stop your bike in the center [sic] of the travel lane where other vehicles ordinarily stop when waiting for the signal. Turn your body toward the camera to appear as large as possible. Video camera technology potentially allows a wider variety of vehicles to be detected than with inductive loop sensors, but the camera must be properly installed and adjusted for this to work. If such a system does not detect you, report the defective signal to your local traffic engineering department.I'm blaming myself for not approaching this thing correctly, until I at least give it a concerted effort to try to get it to notice me. But I never would have thought about this if it weren't for this forum: at this intersection (on a designated cycling route), others ride onto the sidewalk because they don't know about the detection technology, or it's not sensitive for someone on a bike to be detected (at least not without effort, it's not).
