Perhaps this device, "The Red Light Changer" could be an urban cyclist's dream come true when playing with the big boys on wheels on urban streets, that seem to have been designed for those lugging around a couple tons of metal.
The makers of this product claim that it creates the illusion to the the traffic sensor loops that you are a big car, even if you are on a 20 pound non-magnetic, light weight bicycle, or motorcycle.
If this works, it would be a boom to bicycling on streets with the magnetic loop traffic sensing devices, including the intersections with right hand turning lanes with their seperate detectors.
Here is what they say on their website:
The end to excessive waiting at Red LightsFor more info check out their website: www.bikerhiway.com
The RLC-40 Red Light Changer sends out a strong magnetic flux field, causing the sensor to "see" your motorcycle as if you were a large steel vehicle, inducing a signal in the pavement sensor loops, thereby triggering the traffic light to turn green.
How does it work?
The RLC-40 is a specially designed device which uses an extremely strong, patented Neodymium-Boron-Iron magnet to make a motorcycle visible to the traffic-sensor loops imbedded in the pavement at most traffic light intersections. These wire loops act like metal detectors and are designed to sense the metallic mass in an approaching vehicle, and to signal the traffic light to change from red to green, after a short delay. Unfortunately, most motorcycles don't have enough metal to set off the sensors, so the light doesn't "see" the motorcycle waiting at the red light. Mounted at the bottom of the motorcycle, the RLC-40, sends out a strong magnetic flux field, causing the sensor to "see" the motorcycle as a large steel vehicle, inducing a signal in the pavement sensor loops, thereby triggering the traffic light to turn green.
