on Red Light Cameras
Since you guys are arguing over something you have no idea how it functions.
The redlight photo enfocement system gets a signal of the "yellow" and then the "red", it also has sensors to detect motion before the violation line (crosswalk or stop bar). This can be inductive loop sensors (the round things in the road) or a radar system.
IF there is motion AND the signal is yellow and is about to turn red the motion will be captured. However the systems are designed to show the rear of the car with the redlight visible and the car clearly traveling over the violation line.
It doesn't take constant video, AND portland hasn't changed from Still film to Video yet so currently it takes two pictures, one face shot IN the intersection and one rear shot showing you cross the violation bar with the light red.

I find it very discgusting that our tax dollars are spent flying around after wolves. Is it not enough that we've almost exterminated wolves completely from the country.
Now Ranchers again get priority over the natural environment.
When will we get the clue?

No the problem is all the darn people and the fact that they're all driving cars.. get on your bicycle.

The light at Marion and commercial is the one you're talking about.
The camera only takes pictures if you DON'T stop or come close to a stop.. YES a "california stop" IS illegal

Yellow light timing is based on factors such as limited visibility, grade, speed limit, amongst many other factors. Traffic engineers set this timing in the office then adjust it in the field while observing actual traffic flow.

A little something on the way signals work.. there is a "four cycle system" in place.
The light is green, the crosswalk hand is flashing red.. when the hand changes from flashing red to solid red the light is about to change to yellow, then obviously red.
So if you are aware it is EASY to know when the light is going to turn yellow.

These systems are often installed at intersections where increased traffic flow has caused a rise in congestion and led to people running redlights due to their self interest in their own schedule.

The above is great.. The city actually extended the left turn yellow at 25th and Mission to ensure that people would have time to clear this large intersection.
There is huge misunderstanding of how these systems work, they do not attempt to capture you for running a yellow light. They only get you if you are at least a car length behind the violation line when the light turns red and you keep going.
People's biggest problem is that they don't want to take responsibility for their own actions.
The accident occurance at intersections following the installation of the systems drops significantly.
These systems do NOT cost a couple of hundred thousand dollars to install but rather 50-100k.
I take exception to the call from the police officer the intersections where they choose to install these systems are intersections that have a large problem with red light runners due to the size and complexity of the intersections.
Anyway these systems are a great improvement in driver enforcement.
