Instead of riding into that "coffin corner," I'll usually just take my place in line with the motor vehicles.

Cyclist dead after being hit by garbage truck in west Ottawa
Right, no seeum.
Driving the lowly Ford van, the right side will hide a 10x20' area. Big deal ? well, if you're occupied with ahead and left vision decisions the yes a big deal. Pulling a trailer with http://www.ritchiewiki.com/wiki/file...CK_TRACTOR.jpg 20'x30' ? I have TV. Which is the answer. not expensive, 1 $70, 1 $50. One side right with screen under the instrument panel lip and one mounted hi on rear covering rear and rear left. Motorhome people have TV. Other some drivers find this annoying as I can see the road and so drive it. video express: http://www.bhphotovideo.com/c/buy/Ve...2/N/3880127373 BH sells dummy cameras for Xmass gifts if you have a dummy on the list. |

Not done. if you go, keep a thumb on the horn pad maybe flick lights at night. The dead caught under a semi...truck rights as well as law rights. As I wrote abt the kid under the boo truck like its just not done. |

No stripe or green paint offers real protection. Instead of riding into that "coffin corner," I'll usually just take my place in line with the motor vehicles. The trouble is more often that the cyclist is already there when the truck comes up alongside, and of course, once the truck driver has their front bumper (fender) ahead of the cyclist, the cyclist ceases to exist as far as the driver is concerned. This is the rationale behind advanced stop lines/boxes - it gives the cyclists somewhere to wait in front of the traffic, where they are directly in the drivers' line of sight. Designed and used sensibly, they work. But there are more bad designs than good ones, and very little education on how to use them properly. It seems to me the education part should start first, since the problem exists with or without bike boxes. It exists even without bike lanes, although bike lanes usually exacerbate it, by actively luring cyclists into that dangerous move or dangerous spot. (Yes, SR, some things one can do on a bike _are_ dangerous.) When I was first learning this stuff, I was told that if a cyclist is matching the speed of motorized traffic, there's no reason to be off to the side; he should therefore be at lane center. And when all traffic is stopped for a stop sign or traffic light, the cyclists are matching the speed of motorized traffic; so they should be at lane center. That's almost always where I am in that situation. Yes, filtering forward is sometimes valuable. But cyclists need to learn that it's a non-standard and potentially hazardous tactic. They need to know exactly why, and they need to balance the benefits against the potential detriments. If the line is so long that I know I'll miss the eventual green, I may carefully ride up along the cars, but stop just behind the first car - the one that might turn right. That way I'm visible to the driver of the second car. (But to me, that feels like jumping a line for theater tickets, so I rarely do it.) It's at least as reasonable as motorists jumping the queue to pass a cyclist on faster roads. Probably more so, since the cyclists aren't the ones responsible for the congestion. There's some logic in that attitude. But again, I try to balance potential benefits vs. detriments. Usually, filtering forward would save me only a very few seconds of travel time, since I'll make it through the green light anyway; so I don't bother. As with the motorists who impatiently pass a cyclist, I don't plan on getting rich or saving the world with those few seconds. I have done some fairly serious filtering in big cities, but it's been because of long lines or traffic jams that would have delayed me several minutes. But I suppose even that delay would have been negligible in the context of a lifetime. -- - Frank Krygowski |

I have done some fairly serious filtering in big cities, but it's been because of long lines or traffic jams that would have delayed me several minutes. But I suppose even that delay would have been negligible in the context of a lifetime. That rather shows the difference in local traffic conditions. Here, we don't regard a line of traffic at a red light as a real queue unless it extends beyond a single cycle of the traffic lights. If you get through on the first green, it's just "getting caught at the lights". Queueing is a normal part of commuting by car into most larger towns or cities in the UK. Short queues are only a few hundred yards, but some go on for miles on end, particularly into the larger cities like London, Glasgow, Birmingham, Leeds, or Manchester. And they are normal, everyday traffic. Chuck a lane closure or two in, or a traffic collision, and it can get quite badly congested, delaying traffic for anything up to a couple of extra hours. This is one of the biggest reasons for cycle commuting here - it's faster than driving, for (each way) distances up to between 10 and 40 miles, depending on the size of the city you are commuting to. So giving up filtering means giving up one of the main advantages you have over the cars. Cycle commuting times, even when they are a little longer than those by car, are far more predictable. But for many cycle commuters in the UK, filtering saves them 30 minutes per day, every day, and more if something has messed up the traffic. That is very significant, even in the context of a lifetime. It's the equivalent of having your work paid vacation allowance doubled.
