Traffic-light weight switches?

About steel toes - I have heard about a case where the shoe/boot bent on an off and the steel toes chopped off some toes. Not telling people not to wear them.... it is highly unlikely, but just something to think about.

can happen, but I don't think its likely in an off, unless something impacts it - alot

I'm with others who (a) ride right up to the pedestrian crossing in the hopes that a car will pull up behind me and (b) after waiting through at least one full traffic light cycle have a good look around and if no other traffic I just go.

Maybe it's living in Sth Auck but I don't like the feeling of vulnerability sitting like Nigel Nofriends at a set of lights, especially at night

Thats CTOC, the Christchurch Transport Operations Centre

They sort the traffic lights.

Wellington also has a TOC, as does Auckland.

Many bikes have aluminium wheel rims and as has already been suggested aluminium is not a conductive metal. The metal side stand down generally works.
Don't forget to be in neutral.... 😉

Even if rims are steel the insulation of the tyres would prevent conductivity.

What, are you people talking about conducting?

Aluminium is definitely a conductor.

mate if you have an old dead PC hard-drive pull it apart and take the 2 strong rare earth magnets out of it / stick to bottom of frame of bike, no need to glue etc, they are strong as feck don't get your fingers inbetween 2 of them -- should do the trick and cost you nothing...

Even better stick them on the oil filter if it's low enough, or the drain plug. Kill two birds etc.

The solution would be a painted circle at the intersection with a metal plate sensor in the middle for bikes to stop inside. This will not happen due to the revenue they can get from motorcyclists who give up waiting maybe.

They do it for cyclists at a lot of intersections. Just look for the small diamonds marked on top of the loops.

There are a couple of intersections in town where I can no longer be bothered waiting 45 seconds when there is no traffic coming. If the signals were so smart they would throw a short green phase in but that is beyond the systems used here. So at a couple of places I might wait a bit and then proceed but the first thing I am going to check for is Police cars. I would rather not get caught than try to to explain my way out of committing a quite obvious offence.

So if I had known about them years ago would they have got me off the ticket I got if I was able to prove to them the lights at the interesction I was ticketed at did not trigger for bikes? The ticket I got was failing to comply with the signal as opposed to failing to stop.
Even if this could be done it would require having to take a half day off work to go and see them plus they would have to road cone the intersection while you did a demonstration with your bike. The solution would be
a painted circle at the intersection with a metal plate sensor in the middle for bikes to stop inside. This will not happen due to the revenue they can get from motorcyclists who give up waiting maybe.

OR the complaints from riders about the reduced friction coefficient of a steel surface in the rain would put the kibosh on your plan as riders came off with a lost front and slid into the cross traffic.

My post was to point out to the other poster that the rubber in tires acts as an insulater between the rim and the road. Maybe the other poster was meaning that the sensors are actually magnetic and if thats the case alloy rims or side stands will not "conduct" to use their lingo.

As has been stated MANY times in this thread, they are inductive sensors, not magnetic but along vaguely similar lines. Conductivity has nothing at all to do with their operation.
They will detect any metal, but some better than others. Also the angle of the metal with respect to their field matters.
Iron and steel are most easily detected and so extending the side stand MAY improve a bike's "detectability" as it makes the object appear larger to the field

[Bass]

It seems to me a sensor technology imrovement is required if all bikes are going to be able trigger lights like cars. Putting your stand down in "hope" just sounds nonsense to me.

It is, but as has been stated many times in this thread, if you find a problem, contact the controlling authority as they can and do adjust the sensor sensitivity

[Dave-]

That is fine in theory but not logistically possible for the reasons I pointed out in a previous post as it would require you going in and they would have to road cone the intersection while they calibrated
the sensor for your bike and for all you know this setting may not suit other bikes as has been pointed out by other posters if they have a lot of alloy and not steel in them. If controlling authorities are aware that the sensors
are not perfect for the detection of motorbikes you should be able to get any failing to comply with a signal ticket waivered where no cars are present at an intersection to trigger the signals.

It's more likely that a technician will look at the data recording for the traffic light induction system and lower the trigger threshold.

No cones, no motorbikes, no going in, no calibration, no worrying about other bikes.

[Dave-]

The problem with your theory is that if a motorbike does not trigger the sensor it will not show up in the data anyway unless you mean that they can look at the photo of your bike waiting from a red light camera if you give them your reg number. Not all lights would have cameras either.

No, but the technician will know by experience that the magnitude of a motorcycle is typically some proportion of a car (lets say 1/3rd) the magnitude of a car, he can thus set the trigger somewhere below 1/3 to know he will probably fix the issue.

If you call again he will just lower it a little further.

Actually yeah, you're right, you definitely need to take time off work and they definitely need to get out a cone and block off the lane while the technician calibrates the magnitron to your specific motorcycle. But you will need to hold your engine on exactly 4321rpm to generate enough electromagnetic torque to get a good reading. What a pain eh? You're totally right about the government gathering revenue off impatient motorcyclists running red lights too, that's got to be one of their highest earners right? Probably paid for the flag referendum. Aye?

Psst guys, what I wrote above is all bullshit, if you have trouble with lights call your city council

Fuck sakes.

It is an INDUCTANCE loop! NOT a fucking direct cunting contact!
You fucking twat!


As a demonstration.
Please go and stand next to an electrical outlet. Guess what, nothing happens.
Now, go and hold a pair of scissors, then insert it into the holes in the socket.
Please ensure the switch is on.

See the difference?

Now, hold some rubber around the scissors and re-insert into the socket.
See the difference?

Or get a bunch of them and stick them directly to all the plates on your route to/from work?
