Red Light Cameras could be trouble for Bicyclists
from the Cedar Rapids (Iowa) Gazette letters to the editor:
There might be a big problem for bicycle riders in Cedar Rapids with the red light/radar cameras now being installed. As a bicycle wheel rotates on a bike that is moving forward at 20 mph: A. The part of the wheel touching the ground is moving forward at 0 mph. B. The center of the wheel and the bike itself with rider is moving foward at 20 mph. C. But, the spokes at the top of the weheel are moving forward at 40 mph. This is just simple mathematics for a rotating wheel. If the red light/radar detects the spokes at the top of the wheel instead of the bike itself, I will get at ticket for travelign 40 mph wihile I'm only traveling 20 mph. I see a potential problem for bicycle riders in Cedar Rapids. author name snipped |

My attorneys just got one dismissed as the camera clearly showed I had indeed not run the light. Red light violations are epidemic, and dangerous, but not every accused is guilty either. -- Andrew Muzi www.yellowjersey.org/ Open every day since 1 April, 1971 |

Besides, in all likelihood, the radar will pick up the strongest reflection, which will be the rider's body (except velomobiles). Not losing sleep over this one yet. -- Tom Sherman in CR |

Although I'm not sure how a red light camera, or the logic described, applies to a bike in the first place, because- #1: If you're actually stopped at the red light, your speed is going to read zero, no matter where on the wheel it's measured from. #2: If you're moving through an intersection against a red light, your speed is irrelevant... any speed above zero is illegal. #3: The biggest mass on a bicycle is the rider, and that's what the camera is going to spot. Not some tiny point on a wheel. The camera isn't going to be looking for something that's specifically rotating. #4: They have no way to identify you to mail you the ticket. --Mike Jacoubowsky Chain Reaction Bicycles www.ChainReaction.com Redwood City & Los Altos, CA USA |

Per Rick:
If the red light/radar detects the spokes at the top of the wheel instead of the bike itself, I will get at ticket for travelign 40 mph wihile I'm only traveling 20 mph. I see a potential problem for bicycle riders in Cedar Rapids. As long at the bike does not have a license plate, it seems like they would be hard-pressed to ID you... or are we talking a cop manning the camera on the spot with a chase car? -- PeteCresswell |
