Changes in German traffic law loosen restrictions on cyclists

The German Cycling Federation (ADFC) has posted a page describing changes which remove some restrictions on cyclists. I have prepared a translation of the page.

Please keep in mind that translations do not necessarily reflect my own opinions.

I also have posted translations of other documents about German traffic law and cycling conditions.

Cars declare war?

I’m commenting here on an article in the Washington, DC City Paper blog,

R. Crumb's history of America

R. Crumb’s history of America

There is No War on Cars.”

Excerpt:

“Except that there was a car war. It was just in reverse: Cars were declaring war on cities across the country.”

And a commenter on an e-mail list adds:

I’d add “and people” after “cities”.

Cars are machines and cannot declare war. Mischaracterizing the degradation of street use as a war makes it harder to understand. It is a tragedy of the commons — misuse and degradation of a resource held in common, where individuals reap the benefits but society at large is burdened with the costs. Sometimes the very residents who once walked the street now drive and park cars in it — but also outsiders do, as cars are mobile. On local streets, this typically occurs slowly, by degrees. The classic cartoon by R. Crumb describes the situation well enough. (Click to enlarge).

Hmm, not the first time I’ve said something like this.

The transition occurred in US cities in the early and mid 20th century, but I’ve witnessed a more recent example: over the years, where I go on vacation, more and more people have built cottages farther away around the lake. These people are more hurried, and they and have little investment in the safety of children crossing the street in the middle of town to get to the lakefront. War? The change is hardly noticeable from one year to the next, but it is dramatic now compared with 60 years ago.

On the other hand, political battles — between people — do occur over destruction of neighborhoods to construct highways or widen streets, and over reclaiming streets.

I often see similar anthropomorphizing of machines in descriptions of traffic incidents e.g., “the car didn’t see me”. That wording may become more appropriate with self-driving cars but Heaven help us if cars are programmed also to be able to declare war!

Right-turn lane as dual-destination lane?

I’ve had criticism from an unusual side about the video below. The complaint, from another cyclist, was essentially that I was not following the rules of the road, not operating as the driver of a vehicle, by riding straight through in a right-turn lane. Most criticism about my cycling, and my cycling advice, comes from people who would rather that cyclists not have to ride on roads at all!

Allston to Cambridge by Bicycle via River Street Bridge from John Allen on Vimeo.

To answer this criticism, let me first provide some background.

Anyone who uses the roads in the Boston area, whether as a cyclist, motorist or pedestrian, soon discovers that the street markings often contradict the requirements of normal traffic movement. Of course this is what knowledgeable cyclists complain about as it applies to bike lanes — emphatically so in the Boston urban core, where there is rarely room for bike lanes outside the door zone. Door-zone bike lanes have been installed anyway ever since the Cambridge bicycle coordinator introduced them in the mid-1990s. (Now she has moved on to X-merges, bicycle sidewalks, jughandle left turns and bowling-alley bus stops, and the City of Boston is working to play catch-up.)

We don’t only have bike lanes in the door zone here, we have bike lanes in the taillight zone — like this one on Massachusetts Avenue in Cambridge.

Bike lane in taillight zone, Cambridge, Massachusetts

Bike lane in taillight zone, Cambridge, Massachusetts

When I had the opportunity to ride in Albuquerque, New Mexico a couple of years ago, I had a real eye opener: I saw and rode on bike lanes which are mostly functional rather than dysfunctional. They are on streets without parking; motorists merge across them to turn right. I realized that bike lanes in the Boston area give others a bad name.

The Boston area has a terrible reputation for bad driving compared with other cities. In my opinion. strongly backed up by statistics, this reflects cultural differences rather than reality. There is somewhat of a chip-on-the-shoulder, butt-into-line attitude among many Boston drivers. It probably goes back as far as the Blueblood vs. Irish struggles for political power of a century and more ago. Some drivers feel a sense of entitlement and an emotional need for self-assertion. But the rudeness also at times reflects the practical need to get going. A Boston driver more often has blindly to inch out into the path of a vehicle which has the legal right of way, simply to get into the stream of traffic, than in most other American cities. A cyclist who doesn’t understand this will feel continually abused and endangered; a cyclist who understands the need to assert lane position and right of way finds Boston a very easy and safe place to ride. I describe how to be that cyclist, here.

There aren’t good statistics on bicycling, but Boston has the lowest rate of pedestrian fatalities of any of 52 major US cities. Boston drivers may be rude, but also they are clearly more attentive than elsewhere. They have to be. They know that they have to keep their eyes open, and that the street design and street markings have to be taken with a grain of salt.

The conflict between markings and traffic movements here in the Boston area didn’t begin with, and isn’t restricted to, bike lanes. It results in the first instance from an attempt to impose standard road markings and channelization on streets which are too narrow to accommodate them, or on multi-way intersections which are too complicated.

In order to accommodate parking, there are quite a few travel lanes too narrow even to fit a conventional dual-track motor vehicle. Here’s an example.

Narrow travel lane next to parking, Franklin Street, Framingham, Massachusetts.

Narrow travel lane next to parking, Franklin Street, Framingham, Massachusetts.

There are also multi-way signalized intersections where traffic engineers threw up their hands and let traffic enter from more than one leg at a time and merge inside the intersection.

And now, zeroing in on the topic of this post, there are numerous situations where an empty right-turn lane parallels a congested through lane, and neither lane is wide enough for side-by-side lane sharing. Often there is also a receiving lane or shoulder after the intersection — as in the example shown in the video.

I completely agree that it is foolish and hazardous for cyclists to ride near the right side of a right-turn lane when headed straight across the intersection. That is the “coffin corner” situation that we lament when it kills a naive cyclist. But, on the other hand, I consider treating an empty right turn lane with a receiving lane or shoulder after the intersection as a dual-destination lane, and riding in its center or toward its left side, only to be a variation on the decades-old advice to choose lane position according to the rules of motion, and ignore the bike-lane stripe. I’m not alone in this, not at all. Installations formalizing this treatment have been made in a number of places in the USA. It is accepted under the Manual on Uniform Traffic Control Devices if shared-lane markings are used, though state laws generally still do not allow it. It is still in the experimental phase if a through bike lane is to be installed inside a right turn lane. That is documented on this page on the FHWA site.

Most importantly though, treating a right-turn lane as a dual-destination lane when it is empty, or lightly-used, or carrying slow traffic while the through lane is blocked, and riding at its center or left side does not violate the rule of destination positioning and does not lead the cyclist into a conflict. I yield when entering the lane (if there is any vehicle to yield to) and I never place myself to the right of right-turning traffic. I have never gotten into a hazardous situation by doing this. I must anticipate that a driver waiting in line in the through lane to the left may decide instead to turn right and enter the right-turn lane late. This is the same concern as when overtaking any line of stopped traffic, and the countermeasure is the same; stay far enough away from the stopped traffic to be able to avoid a merging vehicle.

In my opinion, the assertion that a cyclist should never ride centered or left in a right-turn lane when preceding straight across an intersection is rigid, legalistic, and impractical. But on the other hand, it doesn’t make sense everywhere, either as an informal practice or a standard treatment. That is why, in my opinion, a standard is needed to establish where it may be formalized, and education is needed, as always, so cyclists will be able to judge when it is advisable or inadvisable.

Further information: I’ve had the same issue raised about my advice on riding the 9th Avenue sidepath in Manhattan, and you may read about it in the documents, photo captions and video linked under the 9th Avenue heading here.

Specialized S-Works tandem: Shafted, but Shifted

A California bicycle shop posted the photo below of a tandem made by Specialized S-Works — the part of the company which produces high-end, innovative bicycles.

Specialized S-works tandem

Specialized S-works tandem

This is a show bicycle and concept bicycle, “must be better because it’s got a carbon-fiber frame and has (wow), shaft drive.” However, drive from the rear crankset to the rear wheel reverts to chain drive, which allows of multiple drive ratios.

A reader where the photo was posted on Facebook remarked that “formula one racing motorcycles all use a chain drive. With that shaft drive the power has to change 90° twice. Minimum 5% power loss compared to chain drive.” As only the power from the captain (front rider) passes along the shaft, power loss on this tandem might be somewhat less.

The frame has to be heavier to resist the torque produced by the shaft. A tubular shaft could probably be as light as a chain.

With no seat tubes, the frame may provide a greater suspension effect, but at the cost of greater weight due to lack of triangulation. In a tandem, there is a major requirement for torsional stiffness around a longitudinal (front-to-rear) axis, and computer analysis may have shown that the structure necessary to achieve this also optimizes strength and vertical stiffness/suspension without seat tubes.

The saddles and seatposts are integrated and non-adjustable. Saddle height can only be changed by replacing a saddle. Handlebars can only be adjusted by replacing the entire front end assembly. This bicycle, then, is effectively limited to use by the same pair or riders. If not for the inefficiency of the shaft drive, I’d say that it might be suitable for pro racers, for whom cost is no object. But is there any tandem racing at that level?

Useful new ideas sometimes spin off the design an impractical concept bicycle — but in this case, in my opinion, they would relate the ride quality and durability of the unusual frame, rather than to the shaft drive.

A vision for the future?

I recently received a membership solicitation from the Boston Cyclists’ Union — the new kid on the block in Boston Area bicycling advocacy. The image of a family happily enjoying travel by bicycle is printed on the envelope:

Here’s the image. How, uh — sweet.

Boston cyclist Union picture of happy family.

Boston cyclist Union picture of happy family.

The child is in a front-mounted child carrier, which I find distressing in itself. it can impair pedaling and steering, and if the bicycle has a head-on collision or something stops the front wheel, the kid can vault over the wheel and go down headfirst. I know that this kind of child seat sees some use in Europe, but on the other hand, the more modern and safer approach is to use a cargo bicycle or tricycle (“bakfiets”) with the child in a low compartment ahead of the adult rider — or a bicycle trailer. Even a rear-mounted child seat is less risky, despite the instability it causes.

Well, yes, they are all wearing helmets — though both Mom’s and Dad’s are tilted back on their heads like sunbonnets.

But also, Mom is riding on the bicycle’s rear rack. Consider the effect on stability, or her getting a foot into the spokes of the rear wheel. For good reason, it’s illegal to ride on the rear rack. This is from Massachusetts General Laws, Chapter 11, Section 11B, the bicycle section, and is typical of law all around the USA:

(2)(i) The operator shall ride only upon or astride a permanent and regular seat attached to the bicycle; a passenger shall ride only upon or astride a permanent and regular seat attached to the bicycle or to a trailer towed by the bicycle.

Why doesn’t Mom for crying out loud have her own bicycle? Or maybe they could get a tandem?

Why does Boston Cyclists’ Union try to recruit members by showing anything so stupid, hazardous, and illegal?

I could comment on the quality of the artwork as well, but I’ll demur on that.

This letter is one for the circular file.

Play Streets — another point of view

I’m writing about a Web page on a Web site of the British organization Sustrans (“Sustainable Transportation”),The title of the page is “How children lost out to cars in the battle for space on our streets”. Here are two photos from that page, comparing conditions on the same street in 1982 and more recently:

Victoria Crescent, Newport [Wales], 1982

Victoria Crescent, Newport [Wales], 1982

Victoria Crescent in the Present Day

Victoria Crescent in the Present Day

That’s quite a change — but was there a battle?

I am moved to state a different opinion. Sure, it’s OK for some streets to be play streets. A street hockey goal often resides in the dead-end street where I live, and that’s fine. Inline skates wouldn’t roll on grass, and the puck wouldn’t slide, either. On the other hand, the collector street that leads down a hill out of my neighborhood isn’t an appropriate place for children to play, and never was.

The Sustrans article doesn’t make that kind of distinction.

Try cycling on any popular rail trail and I hope you’ll notice that bicycle speeds which optimize travel times and provide exercise for fitness are not safe where children wander. My bicycle is not a toy for play in the street, it is a tool for transportation, exercise, sightseeing and riding in the company of friends. For that I need streets where rules of the road apply. Turning a blind eye to the problem with bicycling on play streets is one of the more annoying aberrations of populist bicycle advocacy. To me, it is one more aspect of the fabled toy bike syndrome, and also would go so far as to make motoring more difficult by putting children in the way of motor vehicles.

Certainly, the issue is a bit different in Europe, where urban streets were laid out hundreds of years ago, many are narrow and lack sidewalks, and urban residential areas lack play space. There, streets must more often double as play space. In most North American cities, there is less desire for play streets because there is more space for children to play, without playing in the street.

Characterizing the assignment of street usage as a battle strikes me as skewed, because, at least on local streets like the one in the photo, we would then be talking about residents’ doing battle with themselves. Some of the children who played in the street 20 years ago are the adults who park cars there now. The change in use of the street occurs incrementally — one car parked on the street, then two, etc. The resulting reduction in the quality of street life is slow decay, not a battle.

It’s different, or course, on main streets where the decay is due to through traffic which turns a formerly quiet street into a “traffic sewer”, or where neighborhoods are gutted put a highway through. In that case, residents often do battle with non-residents.

This bears repeating.

I downloaded the following message from an e-mail list. I can’t vouch for every detail, but I am in general agreement.

***************

Frank [Krygowski] posted the comment below an hour or so ago [on March 20, 2013] at the blog article about John Allen and vehicular cyclists.

http://dc.streetsblog.org/2013/03/19/will-vehicular-cyclists-and-the-right-to-park-trump-safer-streets-in-boston/

Might want to go there and vote it up so it will get more attention…

Serge [Issakov]
———————————————————————————————

To me, this article is a poisonous pie-in-the-sky attack on those who actually understand traffic dynamics. From what I can see, John Allen’s objections are logical and specific: Heavy crossing traffic (into driveways and intersections) is very dangerous to cycletrack riders, because motorists can’t see them behind parked vehicles until too late. Fast downhill speeds make that much worse. Snow plowing won’t happen after the slightest budget crunch. Door zone bike lanes kill bicyclists. Riders avoiding those dangers by riding the road will be hassled.

So what do you give in rebuttal? “Vehicular cyclists stop progress” and pretty pictures of a street that’s magically become almost free of traffic.

Let’s look at what’s happened where cycletracks and other weirdness has been installed. Contrary to the promises, Washington DC’s “innovative” bike facilities have greatly increased crash rates, with up to six times the number of car-bike crashes per month. (See “Bicycle Facility Evaluation” at tinyurl.com/DC-innovation ) And many years ago, one of the first American-style cycletracks was installed in Columbus, Ohio near OSU. It was ripped out in about a year, due to the increases in crashes. The fact is, traffic “innovation” generally breeds confusion and surprises. And surprises on the streets are deadly.

This does not mean all special bike infrastructure is bad. But it does mean that each design must be logically evaluated based on actual traffic movements, and on real-life expectations and reactions of motorists and bicyclists. Deceptive and biased promotion like Teschke’s cherry-picked street analysis, or “gee whiz” Netherlands copying, can’t take the place of detailed hazard analysis.

Unfortunately, competent hazard analysis seems to require the input of traffic-competent cyclists. Traffic engineers who travel only by car can’t appreciate things like blind spots and pavement problems a bicyclist must deal with. Dreamers who never ride their bike except on park bike paths are no better, and gazing at a watercolor concept drawings (with almost no cars!) won’t educate them.

Yet isn’t it odd that the really competent cyclists, the ones who know the hazards of doors popping open and crossing conflicts, are attacked by the dreamers’ blogs! Is there another field in which you think expertise should be disparaged, and those with the least knowledge should be praised and respected?

How not to restripe

Gordon Renkes has produced a video showing conditions following restriping at Tamarack Circle in Columbus, Ohio, USA. Here’s a Google overhead view of this rather unusual circular street. Click away the caption balloon to get a better view. You may enlarge this view, or go to the full-featured Google page by clicking on “View Larger Map under the image.

The teardrop pointer is at the location of the Google Street View below, of Tamarack Circle before the restriping. (I downloaded the image instead of embedding the Google image, in case Google redoes the Street View).

Google Street view of Tamarack Circle before restriping

Before the restriping, with the very wide right lane, motorists probably parked most of the way to the corner, and many cyclists probably rode in the door zone.

Here’s the video showing condition following the restriping:

The design does encourage cyclists to ride outside the door zone of parked cars. But, as the video shows, the striping confuses motorists. Among other things, the striping instructs them to right-hook cyclists. In the video, one motorist even right-hooks another. Ohio law says:

“Approach for a right turn and a right turn shall be made as close as practicable to the right-hand curb or edge of the roadway.”

Striping which incites violations of the law risks liability claims.

Creating right-turn pockets to resolve the problems would require removal of a few parking spaces before each entering street.

If parking were on the left at the inside of the curve, sight lines at intersections with streets at the outside would be better (though worse at driveways at the inside, and for drivers exiting parking spaces, due to the curve). A combined bike lane/right turn lane (still “experimental”) would be needed due to width limitations.

Linking to some useful information about bicycle headlights

Joshua Putnam has published some well-crafted commentary on how the brightness of LED bicycle headlamps requires a controlled beam pattern to prevent blinding other users of roads and paths. This relatively new problem deserves attention, and is related to the issue of possible triggering of epileptic seizures by flashing headlights, which I discussed in an earlier post on this blog and which Joshua also discusses.

Support for the Allies in WWII, wrapped around a bicycle sprocket

I wrote to Sturmey-Archer’s European office a few months ago concerning the Swiss-made Vibo three-speed hub described on the Sturmey-Archer Heritage Web site. The Web page about this hub indicates that a scrap of paper which enclosed the sprocket in the shipping box shows German troops marching into Paris. It doesn’t. The page hasn’t been corrected, so I’ll make a correction here.

Here’s the scrap of paper. You can click on the image to enlarge it, and read the caption if you happen to read French.

Here’s translation from the French on the scrap of paper.

Underground mobilization
in the Paris sewers and catacombs

(continued from no. 29)

A city full of passion and hope

Since the start of the invasion, German illustrated newspapers have ostentatiously been publishing images of Paris which the propaganda agencies accompany with strange commentaries. Here is an example: it is supposed to prove that Paris is hostile to the Anglo-Saxon invaders and that it openly supports the acts and cause of its oppressors. While the tank battle rages in Normandy, German power is being asserted in the French capital through the organization of large demonstrations by reserve troops along the avenues and boulevards. The Germans do not seem to be troubled by the developments alongside and below them, appearing to be content to drown out the muffled rumblings of the partisan army in the underground city with the sound of boots on the Champs Elysées. The Germans are surrounded by large crowds which “applaud spontaneously, clap their hands and throw flowers.” But who, then, has checked whether these are Parisians? There are two hundred thousand German civilians in Paris, to whom might be added, as in any large city, a certain number of women of easy virtue. Let us recall 1870 and the well-known heroines of Maupassant’s stories. There is nothing mysterious about this image. The Champs-Elysées? Yes. But Paris? No!

This establishes a few things:

  • The hub was shipped no earlier than the weeks in 1944 after the D-Day invasion but before the liberation of Paris — not when “German troops were marching into Paris,” as indicated on the Sturmey-Archer Web page.
  • Therefore, any lawsuit to stop production of this apparently unauthroized copy of the Sturmey-Archer AW hub did not succeed till after that time (and I suspect, wouldn’t get much attention while the war was raging).
  • As Switzerland was neutral, the hub could have been exported to Germany or a German-dominated country — including French-speaking countries — and so the message might have been chosen intentionally as an indication of support for the Allies against Nazi Germany. Note how neatly the paper is torn to preserve the image and caption!

It is also understandable that a Swiss company would take up manufacture of a copy of a Sturmey-Archer hub during the war. There was no way to get the real thing in Switzerland, which was surrounded by Axis and Axis-dominated countries. Also, production of bicycle components — especially for export — in both Allied and Axis nations was limited by the war. The threat of a lawsuit from England would be much less of a concern than action — legal and diplomatic — by the neighboring Germans; the Swiss manufacturer and/or employees clearly were more sympathetic to the Allied cause, and might also expect customers to be. Therefore, a copy of a British hub would probably be better received than a copy of a German one, even though illegal.
