'[OT]: Automobile traffic light trigger device'

From anothher list I read, someone asked the question if there exists a way to
trigger the lane sensor used to indicated to traffic control systems that a
vehivle is in a given lane.  I ride a motorcycle and don't always trigger these
sensors.  Is there some device that can be mounted on a motorcycle to provide
this service?

Thanks,
Kevin

As a motorcyclist and bicyclist, I've found that the best bet is to do either
or both of:

* treat the sensor as broken (which it is if it doesn't sense you), and do
the legal thing: stop and wait till it's clear. In other words, treat the
light as a flashing red light or a stop sign. This is what the law says to do.

* then, tell the road department that they have a broken sensor. Modern
sensors can easily be adjusted to sense a motorcycle or even most bicycles.

Usually the loop sensor buried in the concrete can be seen. My bicycle is
almost all aluminum. The chain and chain rings are steel. So what I do is
lean my bike way over right on top of the ring. Works every time!

I've heard of others taking advantage of their steel cleats and stepping
on one of the rings. So maybe if you have some steel-toed shoes you can
try that out.

Firmly mount a car to your motorcycle. That ought to be enough mass to
trigger the loop.

As a child I found that simply riding your bike ALONG the sensor usually
triggered it (which in my case was a security gate, I loved causing it to
open like that!). TTYL.

Is that to the front or back of the motorcycle? can you suggest an
adhesive?

Depends on your brakes. If they're bad, you'll end up attaching it to the
front. If they're too good, it'll end up attaching to you in the back.

>can you suggest an adhesive?

I believe it'll be a friction-fit either way.

I once had a really comical experience with these traffic loops.  I stopped
my bicycle on the loop, and a big cement truck pulled up 25 feet behind me,
Too far away to trigger the sensor.  I kept motioning for the guy to move
up, through two red/green cycles during which we never got a green light.  I
finally got off my bike, traced the sensor wire on the corcrete with my
hands, and pantomimed driving a truck over it.  All the while he was
shrugging his shoulders and looking confused.  Finally he pulled up ten
feet, and we got the green.  I don't think he ever figgered out why.  He
must've thought I was just another street Mime.

Next time I'll try laying my bicycle on the coil.

There's always the bad way...
I would like to see someone make one of these with a PIC...but be carefull, I doubt the police like this sort of thing...

I got this out of
    Communications of The New Order
               Issue #1
             Summer, 1993

which can be found at
http://www.attrition.org/~modify/texts/zines/CoTNo/cotno01.txt

This version is the one that I know is used in most cities, thats why this is the only one I posted...There are others in the txt file...such as sound activated and manual...

Light Activated Devices: (This is the one that d00d talked about in Phrack)
This type of traffic controll device is activated by a Pulseating, High-
Intensity Stobe light that sends a signal to a detector located at each major
intersection. This dector holds the light green...if it happends to be green
when your going through it, or speeds up the normal cycle to green in the
direction of travel...(note: This means there is a RED light on three sides
and GREEN only on yours). There is an indicating light located next to the
light detector, assuring the driver that the traffic signal is in controll
by the stobe light.

Ok...The name of the stobe light system is called an OPTICOM. The key word in
the upper paragraph was "HIGH-INTENSITY"...normal car do not have high
intensity lights...even when you put your brights on. The OPTICOM flashes at
over 14 times a second...it almost looks like a regular solid light..but nope.
If you guys don't know what i'm talking about...next time you see a Fire Truck
running with lights and siren...look at the top of the engine and you'll see
it flashing away...actually..I think it's the most noticable thing....

Note: Police cars do not have these on them....and only some Ambulances.
The reason Cops don't have them is because they have a car that is easier to
manuver through other cars and intersections. But a fire enigine..with alot
of water and very heavy can't turn on a dime...you'll be screwed in a second!
So thats why Fire trucks have them and cops don't. SOme ambulances do...so
keep an EYE out for it.

Kevin, I used to have this problem on my 250
bike, it was small and light with very little
steel, ie alloy frame, alloy wheels, etc.

One thing that often works it to pull up on
the coil at the side of the lane, directly
over the long side of the coil, there should
be enough steel in your motor etc to trigger
it there.
