Law'n'Order: Ethical Principles and Practicality

Questions to consider:
  • While motoring*, have you ever tried to scrupulously observe the speed limit, anywhere in the US, any time in, say, the past 8 years? What happened? (Bonus question: Was there bloodshed?)
  • When's the last time you saw a motorist make a complete stop at a stop sign when it wasn't mandated by cross traffic?
  • If you live in an area where cellphone use is illegal while driving, do you see people doing it anyway?
  • Are there stretches along your cycle commute where litter is really bad? (Bonus question: How many times in the past, say, month have you noticed complete fast food bags discarded?)
By now you're asking, "What's your point, Robert?" Fair enough. I've been thinking about how personal ethics are affected by being in a car. I'm wondering if the isolation that an automobile imposes, the sense of being "cut off", somehow enables the motorist to compromise his principles. Is a cyclist different because he's "out there" in the environment with little or no protection? Admittedly, I see plenty of cyclists (in the US at least) do lots of scofflaw behavior. And it's this behavior that I always consider "stupid", meaning dangerous, or ultimately impractical.

Ethics seems to be about finding the balance between the principle and the practicality of the situation. Consider the well-known "four-way test" of the Rotary Club International:
  1. Is it the TRUTH?
  2. Is it FAIR to all concerned?
  3. Will it build GOODWILL & BETTER FRIENDSHIP?
  4. Will it be BENEFICIAL to all concerned?
Notice that items 1 and 2 are about adherence to principle (truth and fairness) and 3 and 4 are about practicality (goodwill, friendship, benefits). Certainly, if an action can be said to meet all 4 questions in the affirmative, it can be said to be ethical. (See this post for more ruminations on the Rotary "4WT", including examples of situations where the principled and the practical collide.)

Traffic laws (and for that matter, littering laws) are thankfully areas where the principled and the practical coincide, or at least overlap greatly. A commenter on a previous post noted that cyclists (and pedestrians) in Denmark were scrupulously observant of traffic laws, and I've noted the same on my travels to Europe, in Germany, Switzerland, Belgium, and Sweden. (France is, well, another story.)

I'm always flummoxed when I see a bicyclist, say, commenting on a blog, defending his right to break the traffic laws. Neither principled nor practical.

*I recognize this blog is not about motoring, and it may be that many readers of this blog in fact never act as motorists. To you, I doff my helmet and bow.

BTW Day, Again

So I went to the Columbia, MD, Bike-t0-Work day yesterday. As I've said before, my feelings at these affairs are mixed at best. This year was about the same as last year, although there were more practical bikes (if not cyclists!) in attendance. I found the speakers more fatuous and self-congratulatory than I remember: at least two county officials sent their aides in their stead, who dutifully reported that "[blank] couldn't be here today because of a scheduling conflict," to which I was thinking, "Yeah, at 7:30 am, it's a conflict with bed." Mostly, there was a air of patronization, of "we say we love you for what you do, but we wouldn't be caught dead doing it ourselves."

Hm. I'm betraying a seriously bad attitude here.

(Truthfully, I did seriously appreciate the Chief of Police who is a fit looking guy and a cyclist, who got up, gave an update on Maryland traffic laws -- hey, we have a Three-foot rule now! -- and admonished the crowd that you have to be respectful of traffic laws if you want respect from motorists. Hear, here.)

The county director of transportation got up and, after talking about mostly nothing for about a minute, and never mentioning any traffic improvements for cyclists, prompted me to shout, "more bike lanes!" which (to my satisfaction) nonplussed him and gained me the bemused looks of fellow cyclists. (I was hoping for a smattering of applause.)

The problem is (as it was last year) is that no one is serious about promoting biking to work. If they were serious, they'd be showing off bike lane planning for the region (assuming same existed,) they'd be touting LCI's teaching "Road 101" classes, there would be little workshops on "what you do (and don't) need to be carrying on a commuter bike." But there's none of that. There are a couple of booths for local bike shops showing off various relevant and non-relevant bikes, there are people talking all starry eyed about how they got county officials to listen to a presentation about sharrows (but no commitments of any kind), and there are county officials waxing ecstatic about how BTWD got them to practice riding so they could show up, and guess what? It was exhilarating! Plus lots of bumper stickers and tee shirts. (Where was the League of American Bicyclists?)

Look, being serious about wanting people to bike to work equals a commitment to painting bike lanes. It really is as simple as that. The few of us who are vehicular cyclists will bike to work anyway (and be perfectly safe,) but the others need bike lanes. New York City has proved this. Studies conducted over the last couple of months show a significant increase in cyclists in New York City following their painting over 200 miles of bike paths (although there is some controversy on the exact numbers). If the powers-that-be really want to encourage practical cycling for all the reasons they say, all they need to do is get out the white traffic paint.

I shouldn't be so negative about BTWD. I was in the middle of a conversation with a county official when a fellow cyclist (fully outfitted in cycling gear) came up and said, "Hey, you're the guy that I see biking to work every day, aren't you?" It made my day.

Jan Gehl, Planner Extraordinaire

A name that I became familiar with only after reading David Byrne's Bicycle Diaries over the Thanksgiving holiday (a complete review is on its way) was that of Jan Gehl, a Danish urban planner who is largely responsible (as far as I can fathom) for making Copenhagen the world bicycling paragon that it is. I have spoken before about Copenhagen and its self-propagated images and perceptions, and frankly, I've been less than complimentary, because I think that the most vocal Danish bicycle proponents confuse cause and effect and fail to give credit where it's due (Mikael Colville-Andersen, in his talk in Washington DC, did not mention Gehl).

But if he is not personally so, Gehl appears to be close to the source itself. He's an architect and planner, and principal in Gehl Architects (who have one of the coolest Flash web front-ends I've ever seen.)

New York has a significant connection to Gehl as well. The New York City Department of Transportation hired Gehl as a consultant to survey its streets in 2007 and, by no coincidence bicycling is up in that city as well. Perhaps related to this connection, the New York Times has seen fit to recognize Gehl in its ninth annual Year in Ideas issue of the Sunday magazine.

Byrne talks about Gehl in several places in his book. He introduces him talking about Melbourne and the success they've had in making their city much more liveable. Byrne describes Gehl as
a visionary yet practical urban planner who has successfully tranformed Copenhagen into a pedestrian- and bike-friendly city.. We here in New York think that's .. all well and good for the Danes, but New Yorkers are .. independent minded, so that can't happen here. But Gehl reveals that his proposals initially met with exactly that kind of opposition over there: the locals said, "We Danes will never agree to this—Danish people won't ride bikes." [emphasis mine]
There are many reasons to be hopeful and engaged after reading Byrne's book, but I must say that I found the above paragraphs to be the most inspirational I'd read in quite a while.

Extreme Cyclist Holiday

I didn't really start out intending to have an Extreme Cyclist Holiday in Houston. I just meant to take my folder along and get some riding in, instead of spending all my time in a car, worrying about gas, parking, etc. Then things just sort of got out of hand.

Let's back up a little. At the last minute, I decided to go to the Rice University homecoming to hopefully see some old friends and hang out some with my older daughter Claire, who helps run a bookstore there. I booked a flight, and found my usual close-to-Rice hotel had some good rates, so I got a room. Then I thought, "Hey, I wonder if I can get from the airport to reasonably close to my hotel using mass transit?" Hopping on the Houston Metro website and entering a couple of addresses, I found that I could catch a bus right at the airport that took me to within a quarter-mile of my hotel with no transfers. Wow. Sixteen miles in Houston for a buck and a quarter. Double wow. (The image at right is from the Houston METRO trip planner, very convenient.)

So, that axed the rental car, which saved me about a hundred bucks, probably a hundred thirty with gas. Ka-ching. But it also meant that my in-town trips would be either by bus, by taxi, or by bike. (Now there's an easy decision.) Houston is flat, and the November weather in Houston is really perfect for riding (high 60's to mid 70's, and not terribly humid). And good weather (no rain) in the forecast.

So, to make a long story short, I spent an entire weekend (three days, Friday, Saturday, and Sunday) in Houston, Car City USA, and not once did I even get into an automobile. It didn't seem strange until early Sunday when I realized that I hadn't been in one. Of course all my old classmates thought it weird, but I caught some whiffs of envy among the incredulity, when they asked, "You're kidding! You BIKED to the party?"

Good things: Saving money, great exercise, the flatness of Houston (my little Dahon folder is great for packing, but really not much for hills), Rice University bike parking facilities (basically, good secure bike racks everywhere), not having to worry about parking a car, Daniel Boone's Cycle Shop, and great weather.

Some people complain about Houston drivers. I was told by the bus driver (friendly guy) coming into town that Houston drivers don't respect cyclists, but I had zero bad experiences over about 60 miles in 3 days. Of course I was in a university part of town, where there are quite a few cyclists, but overall, no complaints from me about Houston motorists.

Not so good things: Houston has the world's narrowest bike lanes (where they have them), and the paving in Houston is the pits. Literally. Basically, Houston is built on the flat gulf-coast plains that have a lot of clay in the soil. This "gumbo" as it is called is just hell on pavement. I found myself weaving a lot more than I wanted to be to avoid really nasty potholes and large cracks.

I even had an accident because of the bad roads! It was late at night and I was riding back to the hotel from my daughter's apartment. I hit a bad pothole (hard to see) and went right over the bars (not hard to do on a short-wheelbase, small-wheeled folding bike.) Luckily, no injuries beyond some bruised kneecaps, as I wasn't going all that fast. Not even any torn clothes.

The funny thing is, I picked myself up and dusted myself off, determined the bike was rideable (it needed the derailleur hanger bent back into proper position) and proceeded home. The next morning, I got up early and looked at bike and saw what I missed the night before: my cyclo-computer was missing. Muttering under my breath at my obliviousness the night before, I hopped on the bike and went back to the accident site (I figured if I waited, there was more chance of it getting smashed by a car) and there it was, flung up in a driveway, fully operational. I clipped it back on and went back to the hotel for breakfast.

But it's been almost 30 years since I had an over-the-bars experience! I'll probably be sore for several more days, but the only cure for that is more riding. I really wouldn't mind not ever going over the bars again, ever. Good thing I was wearing gloves. But the accident seemed to underscore the "extreme" quality of the weekend.

I have to say though, I wouldn't hesitate in the least to do a pure "bike holiday" again (except for the accident part). A little planning can yield a lot of riding, and a lot of fun.

Patch Kit Zen

I've been in some tough deadlines at work, so no posts late October. I've been enjoying riding in the cool autumn weather, enjoying the color, the wet leaf debris on the shoulder not so much, but hey, can't have it all.

Here's a bicycling koan (of uncertain provenance) that has seen a lot of coverage on the Web:

A Zen Teacher saw five of his students return from the market, riding their bicycles. When they had dismounted, the teacher asked the students, "Why are you riding your bicycles?"

The first student replied, "The bicycle is carrying this sack of potatoes. I am glad that I do not have to carry them on my back!" The teacher praised the student, saying, "You are a smart boy. When you grow old, you will not walk hunched over, as I do."

The second student replied, "I love to watch the trees and fields pass by as I roll down the path." The teacher commended the student, "Your eyes are open and you see the world."

The third student replied, "When I ride my bicycle, I am content to chant, 'nam myoho renge kyo.'" The teacher gave praise to the third student, "Your mind will roll with the ease of a newly trued wheel."

The fourth student answered, "Riding my bicycle, I live in harmony with all beings." The teacher was pleased and said, "You are riding on the golden path of non-harming."

The fifth student replied, "I ride my bicycle to ride my bicycle." The teacher went and sat at the feet of the fifth student, and said, "I am your disciple."

Why do I post this? It came to mind late last week. I had done my usual morning preparations, (made breakfast, made coffee, made and packed lunch, packed my change of clothes,) and, as I was just ready to go out the door, loading my backpack/laptop bag into the other pannier, noticed that my rear tire was flat. I cursed under my breath, because I should have seen it the first thing, but wasn't paying attention. I considered changing clothes and driving in to work for no more than 2 seconds, and then got my agitation under control and realized that what I had to do was to do the very best job of fixing that tire that I could.

So I took my time and was careful. No obvious leaks, no hissing. A slow leak. Putting it in the kitchen sink, no leaks the first pass. Added a little more air, passed it slowly through the water, and turned up the very slow leak (about 1 small bubble every three seconds.) Put a peel-n-stick on it, looked for but couldn't find any persistent hazard in the casing, aired it up, got my kit back together, made it to the office only about 20 minutes late.

The payoff? At the end of the day, ready to ride back home, the tire was still rock-hard. I just love beating a leak and (especially) not having to go back and revisit it.

Two Interesting Articles in surprising places...

Article 1: Slate, which I haven't read since the end of the election season. (I don't miss my addiction to political online writing much!) Anyway, they published a quite good article by Christopher Beam about vehicularists vs. infrastructurists. Here's a quote:
Vehicularists see the potential transformation of America into a Euro-style bike paradise not just as a far-fetched utopia but as an insult. Dedicated bike paths are an admission that the cyclist deserves pity and should be walled off from the world. Bike paths are separate but unequal—a way for motorists to get bikers out of their way. John Forester, the author and engineer known as the intellectual forebear of vehicular cycling, traces the philosophy back to a set of laws introduced in 1944 that relegated bikes to the far right of the road, prohibited cycling outside of bike lanes, and banned them from the street if bike paths were available. (These laws were part of the Uniform Vehicle Code, a national model on which states base their own traffic laws.) Since the rise of the automobile, vehicularists have seen any attempt to treat bikes differently as a civil rights violation.
Go check it out.

On a related (sort of) topic, I've been thinking about the typical legalese in the Uniform Vehicle Code adopted by most states that talks about "[bicyclists] may ride two abreast if not impeding traffic." Certainly our intuition tells us that bicycles "impede" auto traffic, but I think the truth is a little less obvious. If we think about "impeding" traffic as being the same as "congestion" (reasonable enough, I submit), then at least in theory, widespread bicycle use should produce less congestion (by using up less roadway) and therefore bicycles, while microcosmically acting as an impediment, macrocosmically reduce congestion!

Which is a sort of round-about lead-in to article 2, in the Wall Street Journal, which makes the dubious claim that traffic jams, by providing disincentives for driving, are "good" for the environment. (It's of course a rather transparent plea to avoid congestion taxes, but hey..)

Bike fitting

Bike fitting, buying and finding and adjusting a bike to work well with your body, your flexibility, your strength, and your needs, is an important topic. Today I've put together a post that covers some of the online resources for bike fitting, and also briefly discusses fitting services and systems.

On-line Guides: First I'll give a brief survey of some of the online fitting guides. At top right is a chart detailing the topics covered by these sites:

Rivendell Bikes has a nice online guide for choosing a bike. This is predominantly a guide for choosing a frame size, based predominantly on pubic bone height (AKA "inseam"). It has an interesting rule for how to determine the leaning angle of the torso. This is oriented towards comfort and not racing sizing (which really is not addressed by any of these sites.)

Bikerowave (love the name) has a pretty plainly presented (looks like a forum entry) discussion, but the information there is good.

Jim Langley's excellent site has made the posts of this blog before. He presents fitting as a troubleshooting guide. Good if the bike you already own falls within the range of what you need, not so useful as a buyer's guide. (Langley quotes from Ivan Illich -- hm, good topic in itself for some future post.)

Kirby Palm's long discourse on bike fitting is encyclopedic. Anyone who can write this much on a topic probably knows something about his subject. If not, let's hope he gets lucky. Seriously, this is arranged in a somewhat wordy narrative, but is quite comprehensive and useful.

Peter White Cycles has a page on the topic. It provides some general advice on frame fitting as well as advice on selecting the kinds of merchandise Peter sells. (I really like Peter's site and sincerely appreciate the information he provides. I would buy from him a lot more if he made it easier to do so.)

The Colorado Cyclist site has a thorough (if not particularly broad) guide. It uses a step-by-step approach that I like in this kind of guide.

Wabicycles has a frame-spec focused site that is oriented toward fixies. It information is compactly organized and not unsophisticated. Definitely the place to go if you're thinking about converting that old Raleigh from the '70s into a fixie.

Fitting Systems: Let's suppose, however, that you don't feel confident about measuring a bike (or yourself) and just want to have it done for you. There are a couple of bike-fitting hardware systems sold to bike shops whose personnel are usually certified to use them. Perhaps a shop in your area has one of these systems:

Bike Fit Kit: The "Fit Kit" sold to cycle shops to determine bicycle fit. Since they sell the kits, they don't "give away" their methods online, but visiting their site is interesting in what it says about their approach.

The Fitmaster is the all-in-one fitting machine seen in many bike shops. Shops in at least 25 states in the US have these. A nice, integrated system combined with training on how to use it. This is a good investment for any bike shop, it would seem.

Some randomly-chosen services using (probably) one of the above systems are listed below:

Ride Boutique is certified on several different fitting systems. If you live near Ann Arbor and have a couple of Benjamins to spare, this might be time (oh, yes, and money) well spent.

Papa Wheelie's bicycle shops (again, I love that name) in Boston and Portsmouth, NH also has advanced fitting services. They mention the magic word, "chondromalacia," which I suffer from.

Bicycle fitting services in Tampa, FL. Seem reasonably priced.

eBooks: Lastly, you may simply be a book person, and the comfort of the printed page (that is, if you're willing to print it yourself, as these are ebooks) is the way to go for you. (I can certainly understand this.) There are a couple of titles that come to hand, based on my Internet search:

Arnie Baker's "Bike Fit" ebook. If you're a learning-oriented, self-reliant kind of person, this may be for you. A whole lot less expensive than a fitting session, too.

Andy Pruitt's Medical Guide for Cyclists. Ebook. Combines a section on bicycle fitting with a section on injuries / prevention / care.

Across the chasm

The renowned cult author, Robert Pirsig, wrote an article for Esquire magazine in 1977 about cruise sailing wherein he observed that people who had spent years and lots of money preparing for once-in-a-lifetime cruise sailing voyages often cut them short, disappointed and disillusioned, eager to get "back to reality" from their dream cruises that had turned into nightmares.

Here are a couple of excerpts that apply, directly or indirectly, to bicycle commuting, I think:

The house-car-job complex with its nine-to-five office routine is common only to a very small percentage of the earth's population and has only been common to this percentage for the last hundred years or so. If this is reality, have the millions of years that preceded our current century all been unreal?

An alternative - and better - definition of reality can be found by naming some of its components ...air...sunlight...wind...water...the motion of waves...the patterns of clouds before a coming storm. These elements, unlike twentieth-century office routines, have been here since before life appeared on this planet and they will continue long after office routines are gone. They are understood by everyone, not just a small segment of a highly advanced society. When considered on purely logical grounds, they are more real than the extremely transitory life-styles of the modern civilization the depressed ones want to return to.
...
Now, however, with a boat of my own and some time at sea, I begin to see the learning of virtue another way. It has something to do with the way the sea and sun and wind and sky go on and on day after day, week after week, and the boat and you have to go on with it. You must take the helm and change the sails and take sights of the stars and work out their reductions and sleep and cook and eat and repair things as they break and do most of these things in stormy weather as well as fair, depressed as well as elated, because there's no choice. You get used to it; it becomes habit-forming and produces a certain change in values.
Taking responsiblity for my own transportation is such a liberating thing, and I think it's exactly what Pirsig is talking about. What the weather's going to do, how I have to dress for that, how long it's going to take to get to the office, how my legs feel and how steep the rises are, all these things are part of my "daily chores". Every hill is an opportunity to find the perfect gear to carry me. Headwinds are an opportunity to orient my direction to the cardinal points and get a better sense of my space on the map as I go home. That squeak in the chain means that I'm going to have drop it and lube it soon. My right knee is twinging a bit, better gear down. The way those clouds are moving means that the rain will be over in no more than 5 minutes.

Those cars going by me are big and hot. And heavy, really massive. They are big metal-and-glass parlors on wheels carrying large amounts of flammable liquid. Sometimes the drivers are aware of me, sometimes not. Most of the drivers don't seem too happy; a lot of them are distracted, talking on their cellphones.

As I sit here typing this post, two (count 'em) car ads have come on late night TV touting new cars with "driver-assist" technology. You know, computer-aided steering that moves you back into the land if you wanter, or senses when you're nodding off and alerts you. All this stuff is going to put just more stuff between the drivers who buy these (very expensive) cars and reality.

Pirsig is right. Dealing with reality, if made into a habit (and taken in manageable doses) is value-forming and -enhancing. Motorists have their "reality". In their world, what I do is crazy, dangerous, and even childish. (They wonder when I'll "grow up and get a car"!) In my world, what I do is entirely safe, fun, life-enhancing and (especially) real.

I do drive sometimes, when the situation demands it. (I will have to tomorrow.) So it's easier for me to understand the perspective of a motorist. But 99% of all motorists will not have my cycling experience. It's like we are on the opposite rims of a canyon.

Fashionista

Mikael Colville-Andersen (that's him at right) is a film-maker and the blog author over at Copenhagenize and Copenhagen Cycle Chic. I heard him speak at the Washington DC Planning Commission last Wednesday night. Mikael is a good public speaker and a charming and funny guy, and he is promoting a provocative idea about urban cycling and cycling policy:

We could have all the benefits of Copenhagen cycling if we just, you know, dressed a little nicer on our bikes, if we just marketed bicycling as an activity by, um, looking more like a fashion plate.

Mikael cites a lot of statistics (if, for example, you go over to Copenhagenize, you can see a running total of bicycle miles ridden in Copenhagen up to the moment) and makes a number of frankly good points about the Copenhagen environment. He talks about all the bike infrastructure that's being implemented in Denmark, and he spends no small amount of time addressing the fact that cycling is so much a part of the Danish lifestyle that people who do urban cycling in Copenhagen don't think of themselves as "cyclists". To what does Mikael attribute this great example for the rest of the world? To the fact that the Danish cyclists dress well, with a sense of style, (and that the men wear suits). Mikael asserts that bicycling's lack of status (outside of Copenhagen and -maybe- Amsterdam) is due to the fact that we just don't dress well enough.

Mikael, excuse me for saying so, but I think you have your cause and effect either reversed or at best very muddled. Your fashion premise is a fiction. An amusing fiction, and one that we might all like to imagine ourselves in the midst of, but a fiction nonetheless.

I've been pretty tough on Mikael so far this post, (and I beat up on him a little in a previous post) but I will certainly concede that in his talk he does make some interesting and (mostly) valid points about the "values inversion" of the way that cars and automobiles are marketed:
  • Which is truly more "liberating", an auto or a bicycle?
  • Which is truly more dangerous, an auto or a bicycle?
  • Which is truly sexier, driving a car or riding a bike?
  • Should automobiles have warning labels like cigarettes?
and he does a nice historical exposition of bicycle posters, to show how bicycles and bicycling (as a tourist activity) have been marketed over the 20th century. These are valid, and I appreciate all this. And Mikael's "cycle chic" (thinly disguised girl-watching, but hey, I like this as much as the next guy) is supported in this article in Sci-Am about the incidence of female cyclists.

But the promulgation of "cycle chic" is just wrong as primary policy. Why do I say this? Two reasons. One, it's an effect, not a cause. And Two, because there are bicycling advocacy groups who will buy into it because it's easy. "All we have to do is increase our marketing budget and find some good-looking models, and our urban cycling problems will diminish!" Excuse me, but this is reductionist malarkey.

Over the past couple of years, I've spent enough time in Europe, in Belgium, France, Germany, Switzerland, and Sweden, to see the truth about why urban cycling in these places is different from the US. The truth of it is, what make cycling work in Copenhagen (and Amsterdam, Basel, Berlin, Brussels, Stockholm and elsewhere) is the combination of two components:
  1. Motorists' near-universal respect for bicyclists*; and
  2. Bicyclists' near-universal respect for traffic laws.
These two complementary components, while not impossible to enable in the US, are, nonetheless, longer-term and messier than a simple marketing campaign. Making these two things happen in the US will involve "the three E's":
  • bicycle safety education (best if done in public schools from an early age);
  • enactment of laws that protect bicyclists in a reasonable way; and
  • consistent and fair enforcement of those laws.
Denmark has all these things, and that is why Copenhagen residents use bikes casually and don't need to think of themselves as cyclists. (Some of the readers of this blog have already commented on the Danes' observance of traffic laws.) And this has created the secure environment that allows them to 'dress up' when it suits them. Not the other way around.

Postscript: Am I guilty of taking Mikael too seriously when he is intending to be 100% ironic? Hm. It is a possibility. But if Mikael really wants to get the substantive good news out about Danish cycling, there is certainly a lot of it that he's bypassing. Consider this excellent report (PDF) from the English reports pages of the Danish Road Directorate. (It's from the year 2000, but is the most recent paper on this topic.) In a (partial) defense of Mikael's "marketing" position, there is this quote:
It is important to link soft policies (campaigns, instruction etc) with hard policies (infrastructure, taxation etc). The combination of hard and soft policies is necessary in order to achieve a big change in travel behaviour, both regarding transport mode choice and road safety.
Notice that the quote does mention "campaigns" but in the same breath talks about education as well as "hard policies". In fact, the report is such a good report and so well researched and balanced, and give such a good picture of the real policies that need implementing that it somewhat reinforces my picture of Mikael as being reductionist. And mind you, the source of this document is the Danish highway department. Consider how different the US would be if we had our highway departments actively researching and promoting cycling! As just one example, consider the chart below and the story it tells:
But hey, all of this doesn't mean I'm not a curmudgeon :)

*There are exceptions to this, especially in the UK which for some reason tracks the US more closely.

Euro-envy in Basel and Berlin

I was in Europe on business this past week, Sunday through Friday, and spent my time in Basel and Berlin, which are both serious cycling cities. There were crowds of cyclists out, as the weather was mild. Pictures are worth thousands of words, and I'm suffering from mild jet-lag, so I'll just post some pictures and make a few comments. I describe this kind of post as "Euro-envy".

I know I've got a worldwide readership, and those of you who live in "real" cycling cities in Europe and elsewhere may well find this to be just boring tourist shots (and not great photography at that,) and for this I apologize in advance (although there may be one or two pieces of hardware below that are interesting). But this is mainly for those of us in America for whom bicycle culture is still on the outside looking in.

Arrived in Zurich on Sunday AM and took the train to Basel, where I had a day of meetings on Monday. Basel is a beautiful city situated on a bend in the Rhine, nestled in that corner of Switzerland that is right at both the French and German borders. Basel is a quite hilly place, with its share of rough cobblestone paving, and although they have bike-rental right at the Bahnhof, the profusion of streetcar tracks and the difficult navigation of the city's medieval planning kept me at pedestrian status. There is some bike infrastructure in Basel, but really it's just the social contract—well-educated motorists who are aware of the cyclists—that makes things work.

My first image tells quite a story by itself. Family of five. Mom hauling a trailer with kid #3, kids #1 and #2 on their own bikes, with Dad sheperding them. Mind you, this is the heart of Old Basel, at one end of the Mittler Brücke ("Middle Bridge") that crosses the Rhine. Here about 5 streets come together, as well as a couple (at least) of tram lines. True enough, it's a Sunday and a beautiful one at that, but ask yourself: Where in the US could this happen? Nowhere. Pick cities 1, 2, and 3 from League of American Cyclists best cities (I think they're Portland, Davis, and Boulder.) Would you see kiddo #2 on his own bike out there? I'm thinking not.

There were many families out, but this was the largest group that I saw. Lots of couples, with Mom having the child-seat or trailer setup and Dad getting to ride solo. Kind of unfair to the moms, always having to be the ones who lug the kids, but such is life.

Monday was all in meetings inside (it was a business trip, after all) and early, early Tuesday AM I caught the EasyJet to Berlin. (I must admit that knowing what I know about the carbon footprint of flying, and having the availability of trains, I was very tempted to try and build my itinerary around nothing but trains as a mode of transportation while in Europe, but it would have added probably two days to my stay to do so, and so was hard to justify to our company accountants.) Anyway, since I didn't have my next day-long meeting until Wednesday, I had an entire day to hoof it around Berlin with my cell-phone camera at the ready.

Berlin, Brunnenstraße north of Rosenthalerplatz: saw this nifty cargo bike with outrigger "rolling kickstand". This is a Biria-make postman's bike. Just look at the beautiful sweep of that split top tube, coming up to support the rear rack! A picture of the bike in action (being piloted by a familiar figure) with the kickstand up is here. Biria also sells bikes in the US, but not, unfortunately, this lovely model.

Rosenthalerstraße: the sleek iconic quality of this bike struck me. This is a classic Euro single speed. Fixies, even in Berlin, which is a very flat, infrastructure-rich, cyclist-friendly city, have not caught on here. Of the thousands of bikes I saw in use, I saw only one fixie, and it was parked. So think of this bike as "your Fixie's grandmother". Unlike what we think of as "fixies" these standard bikes are everywhere.

Rosenthalerstraße, heading south towards Aleksanderplatz (the omnipresent "Full-screenFernsehturm" TV tower in the distance): typical group of cyclists. Two of the seven cyclists in this picture have helmets. I would say that is about a normal ratio for Berlin. The Basel ratio is slightly higher.

Hackescher Markt: Nifty all-weather pedicab. These were all over. Several different companies running them.
F
Unter den Linden ("Under the linden trees", the broad tree-lined boulevard heading west to the Brandenberg Gate): The two shots, above and below, are the same intersection a few seconds apart as the light turned from red to green. The knot of cyclists are taking up the entire lane and spread out according to their different speeds. This is just Not A Problem in European cities. Sigh.

Charité Medical School, north central Berlin: I thought these little hedged and gated bike-parking yards were very nice. Secure and sightly. They are on the east side of the Max-Planck-Institut für Infektionsbiologie and can be clearly seen on Google Maps' satellite view.

Hannoversche Straße, near the medical school: This is a fairly unusual classic German motorcycle, an AWD. I'm no motorcycle fanatic, and certainly no expert, but I was struck by the aesthetics of this one. Look at that sleek crankcase and shaft drive. What a beauty!

Hauptbahnhof on Invalidenstraße: Right outside the main train station is a group of Deutsch Bahn "CallBikes". It is the German Railway-sponsored approach to city bikes, and it's quite different from Vélib or the others, as it has no fixed stations.

For the CallBikes system, you need a cellphone and an available CallBike (they are scattered everywhere). If the lock on the bike flashes green, it is available for rent. You call the phone number printed on the CallBikes to be texted the four-digit code which enables you to open the bike lock. When you're at your destination, you lock the CallBike to a stationary object anywhere inside the core city area. When you close the lock, a four-digit receipt code appears on the bike's display. Call the number printed on the bike, text the receipt code and the location of the bike and you're done. It will be interesting to see how this system works over time. I did see some people riding them, but I saw a lot more just sitting about.

(Sorry about the blurry shot—my group was walking fast to get to a meeting, and this was taken on the run).

Elisabethenstrasse, back in Basel: The Swiss Flyer is an E-bike produced by the Swiss firm Biketec AG, who have been at the E-bike game for a while. This is a small-wheel (20") version -- they have a lot of 26" styles and even an E-tandem! Most E-bikes, I think, use hub-motors, but this one appears to have a motor integrated with the front chainwheel (and concealed by the chain-guard.) One of my hosts in Basel is shopping for an E-bike. I think sales of these things are just exploding. This shot is a night shot of a window display, so it's a little blurry.

Intersection of Stänziergasse and Birsig-Parkplatz in old central Basel: Another night shot. This is a broad intersection of streets with lots of sidewalk-cafe action going on on a Thursday night in a pretty popular section of town, and the twentysomethings are getting around on.. bikes, of course. Lots and lots of them. (These bike parking areas are also visible on Google satellite view.) The near corner and the far diagonal corner of this intersection are packed with bikes. Most of them are locked with a short, heavy cable lock, which appears to be the security system of choice, much more popular than the U-lock seen more here in the US.

To an American, the most remarkable thing about cycling in urban Europe is it's not remarkable at all.

It's a "Bike" only because it has two wheels...

Here's the "Yikebike", a Kiwi-designed transportation device that is going to get a lot of press as the successor to the Segway. In some ways, it's a worthy successor. Here's the remarkably well-produced marketing movie, replete with Europop-music, neon-green contrail, and catchy phrases.

The Yikebike is a foldable, baggable, portable, minimalistic electric transportation system. It's not an "E-bike", at least insofar as there is no way to pedal the thing when the battery runs out. It's not high-performance, as most average-to-good urban cyclists could whip it soundly over a short course of a couple of city blocks.

The "YikeBike" has been getting more coverage on gadget blogs than on cycling blogs, and this is for good reason. (It's not, after all, a bicycle as we think of it.) Here are some pertinent specs:
  • Range: 9-10 kms (5.5-6.3 miles);
  • Payload: 100 kg (220 lbs.) including baggage;
  • Charging time: 20 mins for 80% charge;
  • Charging cost: $0.15-0.20;
  • Vehicle weight: 10 kg;
  • Cost: Between $5200 and $5900.
There's a lot to like about the YikeBike concept, especially its product design. The folding design is top-notch, really well thought-out, and clever to boot (I love the "penny-farthing" iconography combined with the "Keep-on-Truckin" posture of the rider). The unit, when folded, appears to be actually compact enough to sling over a shoulder in its special bag. The steering system is compact, innovative, and (at low speeds at least appears to be) effective. The marketing (so far) is quite catchy. But as a serious alternative to bicycles (and let's be fair, it does present itself as such an alternative in its movie), it fails. The range is too short as an alternative to cycling (my daily commute is twice the YikeBike's range each way), and certainly too short as an alternative to car-commuting (which it also tries to undertake).

This raises the problematic question: if the YikeBike isn't a serious alternative to cycling or aut0-commuting, what is it an alternative to? The uncomfortable answer: walking. Walking on a very short commute, or walking to and from the bus-stop. Not even an e-bike purports to replace walking, typically they replace hill-climbing. (And that's fair enough, I suppose.) E-bikers will actually pedal on the flats, extending their range indefinitely, although too bad for them on the climbs when the juice runs out.

I say we need more walking, not less, and therefore I predict the YikeBike will join the Segway in the pantheon of vehicles for sore-footed tourists who want to do extended-range walking tours in urban settings. There are a lot of good design ideas there, though.

Postscript: what do I really, really, really like about the YikeBike movie? Check it out. The uber-cool YikeBiker is wearing Chuck Taylor All-Star Black Monos. This is the ultimate shoe in the world. It can be worn anywhere: your local skateboarding park, a cocktail party, with a tux to an opening at the Kennedy Center. It's green, recyclable, and your yoga teacher will like it, because it folds and gives your feet an opportunity to learn how to Walk Right. I own two pair (one high-top and one low) and am happy to bestow on them the Practical Cyclists' Seal of Approval. (Now if Converse only made them SPD compatible!)

Rolling Stop

This morning (monday) on my way in to work, I didn't have a particularly good set of legs (it's amazing how, when you exercise every day, you find days where you are just "sub-par", and you learn to forgive yourself.) But, I had great timing. All the way into work, 9 miles, I didn't put a foot down. Part luck, part skill, part timing. Sort of like poker.

I go through seven stop lights on the way in to work, plus an all-yield traffic circle (more on that in a future post), plus two chicanes, plus 3 smaller traffic circles, plus two stop signs. Only two, and that surprised me when I counted them. Usually I take rolling stops through them. Speaking of rolling stops, it's a topic of debate that more states should adopt Idaho's "cyclists treat stops as yield" law. Here's an interesting YouTube on the topic:



I don't know about you, but this is one of the finest examples of educational 3D animation I've seen in quite a while. Kudos to Spencer Boomhower, the animator. Clearly a pro. It's a pleasure to see good work like this.

Hazards 2: Interchanges

I was having a Saturday-morning kaffeeklatsch conversation with some ex-pats from overseas (there are a bunch of them who live out in Maryland suburbia, who work with NASA, in the diplomatic corps, and for agencies, well, let's just say they don't talk about their work very much.) One of them recognized me as a regular cyclist, because he'd seen me often on our neighborhood streets (I was so pleased), and so I gently (honest!) steered the conversation towards cycle-commuting. One of the guys was from Holland, and of course he liked to cycle "back home", but he said the hills in Maryland were too much for him. Another of the guys (an antenna designer for NASA) said that at one time he lived just 9 miles from his work, and (so he said) he would have liked to bike but there was a big highway in the way and he couldn't figure out how to get across it.

I knew the highway he was referring to, and I cross it regularly. There is an overpass about every mile along its length, but the overpasses are secondary roads, legal to cycle on, but certainly intimidating for the inexperienced. The overpasses can be particularly intimidating, and I thought it might be interesting to throw out the method I use to cross them. (Here's a link to the excellent "Infrastructurist" blog that the image at right comes from.)

Let me say right up front that this is vehicular cycling, and I've come to the realization that it's just not for everyone. I think that VC requires a commitment (and, often as not, a little bit of militancy in that commitment) to the concept that bicycles-have-full-vehicular-rights. It also requires concentration, some athletic ability, and some developed cycling skills. With all these ingredients available, VC is not dangerous, but as I say, it's not for everyone. In the America of today, though, it is the way to become carless if you don't want to wait for the powers-that-be to develop infrastructure. (This is not to take anything away from the Urban Repair Squad.)

The skills required for this apparently obvious maneuver are three:
  • The ability to ride up a gentle incline (as are most interchanges) and maintain a speed, say, in excess of 10 mph;
  • The ability to "ride a line" in traffic, to ride right on a highway stripe and not swerve even when cars bypass at speed;
  • The ability to look back in both directions without leaving your line of travel;
I say "apparently obvious" because in essence all the cyclist does when crossing an interchange is go in a straight line. I've seen experienced cyclists (although not experienced in the vehicular sense) mess this one up, always trying to be next to the curb or shoulder, and crossing too many vehicular lanes in the process. The State of Maryland "rules of the road" booklet is a little ambiguous on the practice of bicycles and turning lanes. It says:
A bicycle should be operated as close to the right side of the road as practical and safe. However, cyclists are expected to use turn lanes.
It doesn't say, however, in this context how bicyclists are supposed to use them. (I've contacted MD-DOT and will post their clarifications here when and if I receive same.)

So, anyway. Back to the topic at hand, which is the interchange. A most common interchange that one would encounter here in Maryland is the classic "cloverleaf" which I've illustrated in an adjacent image.

I've analyzed the crossing of this interchange and find that it contains seven (!) zones that have to be traversed, and each zone requires a separate response. Each zone is unique, but some are similar to others. Take a look at the illustration.

Our intrepid vehicular cyclist is crossing from bottom to top. The primary road (say an expressway) is the horizontal main road. The secondary road (typically a road with a speed limit of less than 50 mph) is the one our cyclist is on. We'll assume the secondary road has a decent rideable shoulder. (This is not necessary, but most secondary roads of this character do in fact have this, so it's a reasonable assumption.)

So, let's descibe the seven steps of getting across a highway interchange. They are:
  1. In this zone the cyclist is riding the shoulder, looking over his left for oncoming traffic that may not see him;
  2. In this zone, the cyclist is "riding the line", on high alert for motorists overtaking, not being aware of him, and crossing in front of him from left to right;
  3. In this zone, the cyclist gets a brief mental rest (on the shoulder again) and looks to his right to assess oncoming traffic from the loop;
  4. In this zone, the cyclist is again "riding the line", on high alert particularly for motorists coming off the primary road overtaking, not being aware of him, and crossing in front of him from right to left. Since there are also cars on the left, this is probably the most intimidating section;
  5. Another brief rest. This is similar to zone 3, as the cyclist should be looking right and anticipating;
  6. In zone 6, the cyclist will either "ride the line" if there is bypassing traffic on the right, or, if the road right-behind is plenty clear, make an efficient crossing to the shoulder. (I say efficient because for obvious reasons this lane is no place to dally);
  7. The last zone, the cyclist has regained the shoulder and is on his way;
So. There you have it, a quite complicated way to get from point A to point B in a straight line. Most experienced vehicular cyclists might well regard this post as both obvious and trivial. But I put it up to make explicit what the requirements are for VC. Mind you, I think the rewards are commensurate, to be sure. Freedom is a wonderful thing.

Cyclist's Log, and A Bargain

First: Mileage at the end of August: 2548. This is 463 miles this month. It would have been more, except for that little 4-day vacation to the Rhode Island shore. But I'm well on track to smash my yearly goals, so no complaints here. Especially not now that the weather is drying out and getting cool both in the morning and evening.

Let's get to a late-breaking item, though, and that is a quality bike available at a bargain—at least, if you are in the market for a practical "urban" bike (that is, I think, the new "third category", after "road" and "mountain".) I don't advertise on this blog, and this is not an ad, just a heads-up on a bike that I'd buy for myself if I needed an urban warrior.

REI has their venerable Transport Bike on sale (must be time for a hardware upgrade) for only $480. This is a bike that has won awards for the best commuter from Bicycling magazine. Internally geared 7 speed rear hub and front dyno-hub. Fenders, rack, lighting, all included. This is one of the very few bikes that I'd take nothing off of. (Well, maybe pedals.) If you're in the market for a practical bike, and especially if you have an REI store in your area (and double especially if you're already a member,) check out this bike. Heck of a deal, but good only, they say, 'til 7 September.

Cyc-Vac-Recon

Cycling vacation reconnaissance is (I suppose you could say) what I was up to the first three days of this week. My wife, younger daughter and I spent a few days on the Rhode Island shore (at Narragansett) doing some hiking, including some hiking on what is probably the number one bicycle tourism spot in the lower 48 (or at least New England). That is Block Island, RI.

Block Island is strategically located between RI and Long Island, and is served by ferries from Point Judith RI, Newport RI and Montauk NY. While there are certainly cars on the island (it has plenty of miles of paved and semi-paved roads), traffic is nonetheless very light, and the locals seem to be very cognizant of cyclists, so (I'm presuming here) automobile-bike accidents are rare.

The island is beautiful, filled with not only natural beauty (sea views and some outstanding cliff-protected beaches) but also much history, both maritime and architectural. The Southeast Lighthouse is pictured at right. It's on the National Register and the Historic American Buildings Survey. It was moved (taken down and rebuilt, I guess, brick by brick, as it's darn hard to move a brick building) back from the edge of the cliff it overlooks to prevent collapse.

Good seafood abounds, of course. The terrain can be intimidating to those once-in-a-blue-moon cyclists; climbing out of the village on Spring Street was an uninterrupted 1-1/4 mile climb. Not terrifically steep, mind you, but still a sizable challenge for a cyclist uncertain of their gears.

While there are on-island 5 bicycle rentals (one rental agency notes "Bikes with 6-27 speeds available"), it seems most on-season tourists brought their own. The ferries were packed with bikes, and they charged $6 to carry a bike, which for an hour ferry ride seemed a little steep to me. Bikes are accommodated elsewhere -- most on-island taxis, for example, have hitch-style bike racks for getting the less conditioned cyclists up those hills.

I won't go into a diatribe of the bicycling errors and risks I saw, suffice it to say that I'm sure many people go expecting a carefree day of cycling (away from those pesky cars) and find other pesky aspects of reality crawling their way into the picnic. I'd be willing to bet that flats, other minor mechanical failures, hills, and sunburn top the list. There is another non-bicycling hazard that exists on Block Island, and that is Lyme disease. BI has historically been endemic with it; however, I was told that BI has eliminated their deer population, and evidently that has had some effect. So, insect repellent is on the list of Block Island musts.

But the island looked great, even if a very touristy destination. It's for a reason. I've got vacation hours to burn at work, so I'm going back in the off-season, you can be sure.

De Pigerne Promenade...

..which is Danish for "The Girls Promenade". Which is kind of how I think of the blog Copenhagen Cycle Chic. I have to admit, it's kind of an envy thing. Let me explain.

Firstly, here's the brief on CCC:

Copenhagen Cycle Chic began its bloglife back in June 2007 when journalist, film director and photographer Mikael Colville-Andersen decided to put a growing number of photos about Copenhagen's bicycle culture into one place on the internet.

A series of social documentary photos about Copenhagen started to include a number of shots of life in the World's Cycling Capital, including fashionable Copenhageners on their bicycles. The feedback about these photos was positive and there was clearly a growing interest abroad in seeing how the bicycle was an integral part of life in the Danish capital. Specifically about how Copenhageners have demystified the bicycle and use it without any form of bicycle 'gear'. Just as the bicycle was meant to be ridden when invented.
I love that statement about "how Copenhagers have demystified the bicycle and use it without any form of bicycle 'gear'". Really? Do the good bicycling citizens of Copenhagen not have to carry locks, has bicycle theft become passé in Copenhagen? Hm. I don't think so, although supposedly "convenience theft" has decreased since Copenhagen introduced their City Bike system. Do the Danes not have to use lights after dark? I can't imagine so. And I know for a fact (by looking at some of nice photography on the site) that bike baskets and panniers are widely used. So I suspect the "bicycle gear" that Mikael Colville-Andersen is referring to is bicycle clothes. Which raises the question:

Why are functional bicycling clothes so reviled, especially in Copenhagen?

I mean, look at the Copenhagen Cycling Chic Manifesto. (Here's the desktop version and here is the blog post.) While certainly delivered with tongue firmly planted in cheek, I mean, come on.

I wear:
  • bike shorts (simple black ones, not team-livery) because they don't chafe when I'm cycling at 15-20 mph;
  • a bright fluorescent jersey to be visible in all weather conditions;
  • cycling shoes for more efficient power;
  • gloves to keep my hands from getting lacerated in a spill; and
  • a helmet for safety.
I admit this may be "geeky" (however that's defined) but this is practical cycling, and it is, after all, the name of this blog. The Copenhageners (Copenhagenites?) sniff at this, because they know they have it good, and they want to flaunt it.

Why do I say they "have it good"? I've been giving this some thought, and I've come to the conclusion that this is a "hierarchy of needs" issue. Most readers will be familiar with Abraham Maslow's "Hierarchy of Needs" often expressed as a graphic pyramid from his 1943 paper, "A Theory of Human Motivation". The original hierarchy was expressed as the following levels of need:
  • Physiological (meeting biological needs);
  • Safety (security of body, resources, property);
  • Love/Belonging (friendship, family, intimacy);
  • Esteem (self-esteem, confidence, respect);
  • Self-Actualization (morality, creativity, etc.);
Now, let's think about the environment of practical cycling. There's a hierarchy of needs here, also, if you think about it:
  • Law (I must have the legal right to be on the road!);
  • Safety (Can I make it to my destination without mishap?);
  • Living Density (How far do I have to ride to work?);
  • Physical Ability (How much strength do I need to do it?);
  • Style (Can I look good or be cool doing it?);
The beauty of Copenhagen is that the first three levels of the pyramid are taken care of. Cyclists are legally supported in Denmark, and are numerous enough that they are well respected on the road. Copenhagen, like most European capitals, is very densely settled (and flat to boot) so that rides are short and it doesn't require significant physical stamina to handle the ride. Which gives the Danes the luxury of being able to focus on Style. Good for them, I say. But, as reported earlier, I'm jealous.

Keep up the promenade, girls. And, by all means, keep looking good. But please, try to not rub our noses in it quite so hard!

Use Case for a Practical Cyclist

There are many particular "use cases" for practical cycling, but few come to mind that are any more compelling than Taking The Car To The Shop. In non-practical-cycling terms, this is one of life's little pains, right? You have to have your spouse/SO/family member take you or pick you up (and burn double the fossil fuel in doing so), or else you have to cool your heels at the auto shop for a shuttle (that's assuming they even have a shuttle), OR you have to get a taxi. Inconvenient, frustrating, and/or wasteful all the way around.

On the other hand, if you:
  • have figured out a good route to/from the shop to your home;
  • have a way to carry a bike on or in the car being serviced; and
  • want an excuse to ride your bike,
..then Taking The Car To The Shop is just a fun couple of hours (except for the repair bill, which is yet another reminder (as if I needed one) that cars are expensive and troublesome!)

Finding excuses to ride your bike (as opposed to finding excuses to avoid riding your bike) is what the Practical Cyclist's life is all about.

Cyclist's Log

Mileage as of end of July 2009: 2085.4 miles.

Considering I had a dud of a May (only 215 miles!) I think this is not too bad. July, wherein I had in excess of 440 miles, has been a great month. I'm back on track to hit my goal for the year. (And I'm starting out August strong.)

Practical Cycling Defined

I define practical cycling most succinctly as "cycling miles that displace motor vehicle miles."

A group of six (only six?) high-school counselors has done a significant bit of practical cycling by touring college campuses (in my stomping ground, in Maryland, Pennsylvania, and Delaware) to check them out for their student counselees. Twelve days, more than a dozen colleges. 400 miles. (Now that I think about it, although that's only 33 miles a day, it still would take some selling to convince most people not doing serious cycling already that they could handle that.) This is significant. Yes, it's billed as "combining a serious tour with their love of bicycling," but this is ordinary people doing a sustained tour at 1/4 to 1/3 the rate of the Tour de France.

The story in the New York Times is here.

I'm impressed, and I hope their numbers grow next year.

Tripping the Lights Fantastic

Trip it as you go On the light fantastic toe -- Milton, L'Allegro

If you do much urban riding, you've probably encountered one of the practical cyclist's banes: embedded loop sensor activated traffic signals. Which is to say, loop sensors that ignore (or rather, fail to detect) bicycles.

There's one on my daily commute home. If I'm a little late on the way home and motor-vehicle traffic is diminished, I can wait through a couple of cycles. Nothing is more frustrating.

Apparently, this is a widespread problem for cyclists. There have been some gadgeteer approaches to this problem involving gluing very strong magnets or large metal plates to the bottom of your cycling shoes. Hm. I carry a laptop in my left pannier, and I'm reluctant to expose it to strong magnets.

So what to do? I've done some research, and have some information to share. I've come to the conclusion that this is a three-stage process; Keep advancing until you find a satisfactory solution for you.

1. Optimize your placement. First and foremost, know where to put your bike on the loop. (This is where I was going wrong.) The green zones in the diagram at right are optimal. (I was using a "Dipole" position on a "Quadrupole" loop. If you are seeing a "Diagonal Quadrupole" loop, you probably live in Davis CA, Boulder CO, or Portland OR.)

2. Know when you can "Cheat". If you use optimal position as noted above, yet you pass through an entire cycle and the traffic signal fails to let you through, then the signal can be considered "defective". Most jurisdictions allow running the light in such a situation. If you do this, be doubly careful! Watch most carefully for traffic that doesn't see you!

3. Contact your local Traffic Engineers. The good news about inductive traffic loops is, they're easy to adjust. The bad news is, you may get ignored by your local traffic engineers. When I emailed my county engineers about the light I'd been having trouble with, their advice was to dismount, walk as a pedestrian across 3 traffic lanes, and actuate a pedestrian call button. I hope you have better luck when and if you have to call them.

Here are some more avenues for research, if you want to dig deeply into the physics of embedded loops:

Goodridge article, "Detection of Bicycles by Quadrupole Loops at Demand-Actuated Traffic Signals"

Tracy-Williams article, "Traffic Signals"

John Allen article, "Traffic Signal Actuators: Am I paranoid?"
