found this one, worth reading. The idea of organized "civil obedience" action sounds great, we should try it :)

Many lights near me are activated by bikes - there is a bike symbol painted on the pavement that will trigger lights when you ride over it. If one of these is not present, and no cars are around to trigger the lights I have no problem running the light. What's the alternative, sit at the light for an hour waiting for a car to arrive?
Thanks for the linkpitt83

I'm working with our town council (more like they listen to me complain and will fix problems when they can) on cycling conditions and alternate transportation. I will forward the link and call for follow up.

What I'm seeing a lot of these days is an even newer technology with sensors mounted on the overhead traffic- signal supporting wires. These sensors - I belive it's a form of video, can sense a car approaching the intersection and which lane the car is in and will then trigger the appropriate traffic signal(s). These sensors do not recognize bicycles, no matter where you position yourself.

A very frustrating situation, and one that's even worse to deal with then the in-ground system. The overhead video sensors are getting more and more common as they are much easier and cheaper to install and maintain.

How can city engineers spec stuff that doesn't respond to all vehicles? Seems to me they have a liability issue here, if it's pointed out and they fail to address it. Bicycles are classified as vehicles and bicyclists are legitimate users of the roadways in all 50 states...

Just wondering, if the sensor is video based, then wouldn't motorcycles have the same problems as cyclists?

Not sure

I've never been able to trigger onewhile on a bike, but have never been alongside a motorcyle at the same intersection to witness what happens.

similar to the outdoor lights some people have in their yard or driveway. A motorcycle is a much greater heat source & is in the traffic lane rather than in the bike lane or shoulder. I've been able to trip them by riding in the traffic lane on lightly travelled roads, but not every time.

When I rode a steel frame I could sometimes trip the magnetic sensors imbedded in the road by zig-zagging over them, but that doesn't seem to work with a C-F frame. Not enough steel to be recognized, I guess. My options are 1) Ride over to the pole and push the pedestrian button (what a pain THAT is); 2) Wait for a car to come up behind (my usual thing); or 3) Run the light after stopping as long as there's no traffic (not often).
