I mean come on. Who thinks it is "right" or even legal to roll through a red light on any type of vehicle...? That's a shame on the riders, no?
(Not to say they should be hit in the first place and there can always be more of a reduction in cars on the street, etc. etc.)
The article literally doesn't mention red light jumping once; bit odd to immediately jump to this much overused straw man topic isn't it?
The video that was provide in the article showed individuals running red lights. That was the basis of my comment.
Ah OK fair enough, apologies. I am a Luddite when it comes to video in news articles and rarely watch them
I'll start with I do not ride a bike, and I did not know this. Thinking locally with how US lights work, this makes sense as you are not heavy enough to trigger most lights' weight sensors.
Sounds like road planning needs to address this failure.
It's magnetic induction sensors I believe, you need magnetic materials.
Most bikes are built mostly out of aluminium (or carbon) now, so don't trigger them.
Not sure who started that myth, but the inductive loops detect any conductive material, like aluminum or carbon fiber, there is no magnetism involved.
They oscillate in a resonant mode oscillator at high frequencies causing eddy currents in ANY nearby conductive material. The eddy currents in the conductive material produce opposing magnetic fields that will reduce the inductnace of the inductive loop, which in turn changes the resonance of the oscillator. The detector senses this change in frequency.
The trick with bikes is to place the bike right above one side of the loop, not stop in the middle of the rectangle.
There were older designs that did use magnets, but like 40 years ago. Civil engineers were well aware of the bike issue.
Wikipedia link for those interested.
Thanks for that, it makes sense when I think about it. It's been a while since physics class!
I can sometimes get them to trigger by going over the return line to the pavement. Still a big problem for carbon bikes though!
Lights don't use weight sensors, they use inductive loops that detect any conductive metal. You just need to park the bike right on the lines visible on the road.
oh, you have never been a member of a cycling advocacy group. The answer is the ginger guy in dreadlocks.
I'd say about 1/3 of cyclists going by the traffic light in front of my house.
