seriously, I stop at every red light - albeit gangstaz paradise and all... I do prefer not to if that's any consollation... And I have no idea how to trigger the things at the robots... I weigh ~90 kg, both my bikes weigh that doubled.  I'm thinking that robots just don't like me  :-\

seriously... I've owned numerous bikes in my short biking lifetime of 10 years, and not a single one has impressed me when it comes to changing the red light to the green light, regardless of the process....

The three things you need to fix anything in the universe: duct tape, WD-40 and a hammer.  If it moves and it shouldn't, use the duct tape.  If it doesn't move and it should, use the WD-40.  Otherwise use the hammer.

was wondering about the same thing last week at a robot in "PE"
found rolling back and then forward again seems to trigger it - or it just keeps you busy long enough not to notice time passing!!!

On a similar topic..I see cetrein traffic light cameras, have been changed to record speed, but they also work with induction loops...i was just wonderring about their acuracy..for exactly the reason that they sometimes are not too acuralte with detecting objects as they are supposed to.

The induction loop at work that opens the gate does not work when it rains...as there is a bool of water over it..and this somehow hinders it's detection capabilities..

Google 'inductive loop'

Quote from: US Department of Transportation
The inductive loop sensor is a relatively simple sensor. When a vehicle reaches the loop, the metal of the vehicle disturbs the magnetic field over the loop, which causes a change in the loop's inductance. Inductance is an electrical property that is proportional to the magnetic field. (See figure 1.) This is how the loop sensor detects a vehicle.

There are a wide variety of possible causes for IL failure ?? such as damage to insulation during shipment ?? but the two most common reasons for failure are poor pavements and poor installation techniques.

read more here: http://www.tfhrc.gov/pubrds/septoct98/loop.htm

And here is an article on how to alter inductive loops so that they will detect even bicycles: http://www.humantransport.org/bicycledriving/library/signals/detection.htm (very interesting...if you want to dig up the road and do the adjustments yourself)

It seems the poor are to blame. I knew those bastards were behind it!
