How could anyone there ever be prosecuted for running a red light, when the system clearly is dysfunctional ? , you wouldn't even need a lawyer to argue this one in court
I'm not boasting, but where I live, my aluminium push bike will trigger the traffic lights, and the only steel is in the hubs and crank bearings.
Clearly there is a technical problem with the red light sensors there, probably not enough loops or the signal processing sucks, how hard is it to detect a change in inductance thru a coil ? Even a cheap FM radio does it accurately with no problem. (by detecting the change in frequency patterns).
Problem here in the US is inconsistency. The US is very large and has 50 individual states. Each state has it's own guidelines for everything and their own road crews. Not just state, but also city, county, township level. Some intersections are triggered by movement, some older ones by weight displacement and some by magnetic force and then there are timers. I believe at least where I live they only use the newer style which detects movement. I don't know how all the intersections near me detect my bike, but I know I don't usually have a problem. I like most here would proceed through the light if I had to wait an extended period of time with no change.
