Austin's Vulnerable Law

The city of Austin, Texas (my old burg) has decided to right the wrongs of the emperor governor of its state and has enacted a three-foot vehicle clearance law to bicyclists and pedestrians. You can read more about it and see a local telecast on this topic here. (Even better, commercial vehicles must maintain a 6-foot clearance.) This is great news, and not just because Governor Rick Perry has to obey this law to get to work (although there is some delicious irony going on here).

When I was in the Austin area around Thanksgiving, I paid a visit to some friends (I will call them Mr. and Mrs. J) who live in the suburbs outside town. We had a great visit, and it was good to see them. And the suburb in which they live is beautifully planned, with linear parks and bike paths. The visit pointed out to me the distance between people who see bicycles as recreational devices and those who see them as transportation. I mean, I recognize the value of hike-and-bike trails, particularly for people who aren't ready to undertake a 10- to 20-mile commute.

While my friends and I were visiting, Mrs. J expressed to me her exasperation about the "social engineering" that the Austin City Council was undertaking in the new bike ordinance and (not knowing that I had a blog where I write about Practical Cycling) opined that bicyclists belong on the paths and not on the road. I judiciously held my tongue (and since Mr. J. was aware of the situation, there was no need to rock the boat). Mrs. J. did bring up an interesting point about the law, expressed as an objection to scofflaw cyclists (she and I are on the same page there) and asked rhetorically, "What happens if I'm stopped at a light and a cyclist comes up right next to me? Am I breaking the law?"

I thought it was a fair question, and looked up the wording of the ordinance. You can download a copy here. It's supposedly identical to the wording of the law that the Texas Legislature passed virtually unanimously and that Rick Perry vetoed (you can't fault the Austin City Council for failing to take advantage of other legislators' work.)

It's well written. It does the following:
  • Defines a class of "Vulnerable Road User" ("VRUs" include cyclists);
  • Directs that motorists shall vacate a lane used by a VRU if there are two or more lanes going in a direction;
  • Directs that motorists shall pass the VRU at a safe distance otherwise;
  • Defines "safe distance" (3 feet for a private vehicle, 6 feet for a truck or commercial vehicle);
  • Directs that motorists shall yield ROW to VRUs when making left turns;
  • Directs that motorists may not overtake and turn right in front of VRUs unsafely;
  • Directs that motorists may not use their vehicles to threaten or intimidate a VRU;
Hm. It goes quite a bit beyond clearances, it really succinctly tries to address the major hazard facing bicyclists. Although it's concisely written, it's a straightforward, good law, and Mrs. J's concerns for "motorists' rights" (as if they needed additional ones!) are ungrounded. Good for you, Austin.

Plan B for Cold Weather

..and when I say, "Plan B", I'm not talking about not riding! Today it's about 20 degrees (F.) out, but clear. A good day for cycling, if you dress right. However, flatting a tire in really cold weather can be a royal pain. In order to fix that tire, you have to pull of those nice warm gloves, and I can guarantee that adhesives just don't work the same in extremely cold weather. (Hm, this seems to be a self-referential kind of post.)

If you flat, it won't be a problem to fix it once you get to your destination; you'll have your patch kit, tools, and access to soap and water for a clean up. But on a cold, blustery day, it sucks to do this outside. I think the best solution is to have a Plan B. The only two Plan Bs that I can come to reasonably are:
  • Calling a (good) friend on your cell; and
  • Public Transit
The first one being self-explanatory (let's hope your friend doesn't drive a Mini), let's concentrate on the second. It's not necessary for a cycle-commuter to cycle along bus routes in cold weather, but it's good to know where they are relative to your ride. (The graphic is an overlay done in Vectorworks of a GoogleMap screencapture of my route over the PDF of the Howard County transit routes. The HCT routes are abstracted enough that this exercise is of but limited value, but you get the idea.)

So in very cold weather, try not to flat. But if you do, have that Plan B in the back of your head. Know where the transit routes are relative to your route, and head to a bus-stop if you flat. (Have the correct change for that fare ready!)

Weather Wuss

A weather wuss is what I am. When the rain is coming down solidly, I still go for the car. Look at that map. We're socked in from Tropical Storm Ida. I still just can't find the motivation to go out when it's really raining. A light drizzle, sure, no problem. But real rain, man. It's just hard to gear up to go out into a situation where the visibility is poorer, the road surfaces are worse, and the drivers are ultimately more dangerous to me.

I'd really like to hear from commuters out there who manage to go out in inclement weather. I'm really just talking rain (not sleet, snow, or ice) here, and rain that is coming down, not just drizzling (like Seattle rain, which I've also enjoyed riding in.) How do you do it? What has made the difference for you?

Blighters Rock

No, it's not really writer's block, I've just been, ah, busy. We're in busy season at Nemetschek, meeting our design deadlines for the next great version of Vectorworks, and I've had my head down.

I've had my head down cycling, also. As I knew would happen, I "made my year" and met my goal of 3300 miles last week. In retrospect, it seems kind of ho-hum. We'll see how many miles I make by the end of the year and I'll try and do some kind of estimation of what percentage of work days I rode to work. I have to say, though, my utilization has got to be really high, if you deduct for business trips. I think I use my car to get to work no more than 2 days per month, at least for the past 3 or 4 months. Good weather (that is to say, reasonably clear weather) helps.

When it comes to understanding urban cycling, there's nothing like statistics. The city of Fort Collins, CO has just released a compilation of statistics about cycle-auto accidents over a 30 month period and I'm working on some analysis of that as well as accident stats from elsewhere. But the news item I've read recently that has I think the most significance is new bicycle usage stats from New York City. Since 2007, the ridership is up 66%. (That is to say, cycling levels in 2009 are 166% of what they were in 2007.) Wow. Check out that chart. (That is a zero-based chart!)

What can account for this? It's pretty simple, really. There's a serious commitment by the NYC DOT to get people bicycling. The city has substantive programs in:
  • Bicycle education and safety;
  • Bicycle parking;
  • Bicycle/Mass Transit interface; and
  • Bike street infrastructure.
The city has created 200 miles of bike lanes in 3 years and is committed to 50 miles of lanes per year until it completes its bike network. Check out the main NYC-DOT page on cycling and drool. For anyone outside of NYC, it is just enviable, to live in a city that has resources and uses them to Make Things Better.

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..)

Impeach Rick Perry

Rick Perry, the governor of the State of Texas, is a lying tyrant and should be impeached.

There might be people who think that statement is just a wee bit strong. But you know, I just don't know how to put it more plainly and simply than that. I'm sure that most readers of this blog know the basics of the story by now, but just in case, let's review them:

The Legislature of the State of Texas soundly passed a bill, SB 488, "Relating to the operation of a motor vehicle in the vicinity of a vulnerable road user; providing penalties," intending to protect (among others) bicyclists in the state of Texas. It was passed out of committee by a vote of 7-2. The bill was passed by a vote of 142-0 (with 2 abstentions) in the Texas House of Representatives last June 2, and on June 3 by 26-5 in the Texas Senate (so I trust there will be no challenge to the word "soundly".) The bill was certified by the conference committee to have no negative fiscal impact on either the State of Texas nor the communities of Texas.

A web page for the bill, from which the text can be downloaded, is here.

The bill would have required motorists to give cyclists and others categorized as "vulnerable road users" at least 3 feet of clearance when passing on most highways. The "vulnerable road users" category would have included pedestrians, highway construction and maintenance workers, tow truck operators, stranded motorists or passengers, people on horseback, bicyclists, motorcyclists, moped riders, and other similar road users.

Texas Governor Rick Perry, in an action surprising to some observers, vetoed the bill last June 19th. (The Texas state Constitution gives the Governor ten days after receiving a bill to either sign it or veto it, I don't understand why this bill could have been vetoed after 16 days. But that's for more expert Texas legal minds to ponder.)

Perry, a mountain-biker who recently broke his collarbone in an accident, said that many road users in this category already have operation regulations and restrictions in state law. He stated,

“While I am in favor of measures that make our roads safer for everyone, this bill contradicts much of the current statute and places the liability and responsibility on the operator of a motor vehicle when encountering one of these vulnerable road users.”

Perry is plainly lying when he says that he is "in favor of measures that make [Texas'] roads safer for everyone." This statement can be explained no other way. (It's not merely a lie, it's a bald-faced lie, one that is so obvious and blatant that it dares to you call it such, and I choose to do so.) So now let's address the "Tyrant" part of my earlier epithet.

Perry as governor of Texas doesn't have a lot of power, really. The real power is in the Legislature (the "Lege" as it was referred to by the late great muckraker and humorist Molly Ivins.) The only real power the Governor has is the veto. Perry has misused this power: In the four legislative sessions completed while he was governor, Perry has vetoed 203 bills – more than any other governor of Texas. He is also the longest-serving governor in Texas history. (What are you Texans out there thinking, anyway? If you elected a fire-hydrant to the office of Governor, at least it would do less harm than Perry!) This petulant and corrupt over-use of the veto authority is taking power out of the hands of the legislature and the people they represent, hence my use of the "Tyrant" epithet.

The state of Texas has a provision for the legislature overriding governor vetoes, but according to this article, there are procedural issues that make overrides difficult. So the Texas Legislature has written a bill providing for a Constitutional amendment to allow the Legislature to call a special session to deal specifically with veto overrides. However, according to Texas Senator Jeff Wentworth (R), Perry and Lieutenant Governor David Dewhurst are conspiring to prevent the constitutional amendment from making the floor of the Senate.

All of this would be moot if the state of Texas enforced the laws on its books (you know, those laws that Perry says suffice.) But they don't. If you're a cyclist in Texas, you have very little protection. Consider the tragic case of Gregory and Alexandra Bruehler. The San Antonio couple were riding a tandem on the shoulder of Highway 16 north of Helotes, TX when a truck struck them from behind. They were both killed and leave behind a 7-year-old daughter. (Heart-rending images of the daughter abound in the blogosphere, and I won't reproduce them here.) Local news reports that “investigators say there are no charges on the driver. They believe this was an 'accident' and that somehow the driver lost control of his truck.” Even though the driver was reportedly exceeding the speed limit. That, dear friends, is the state of law enforcement in Texas (and, to be fair, in other states.)

You might think that, given this (admitted) diatribe, I don't care for Texas. But that's not true. I lived for almost 30 years in Texas, and I love that state, and I love Austin, where I married and had kids. I love Texas, but I've had enough of lame-brained Texas politics. Just like another stupid mountain-biking governor of Texas, this one should be impeached.

Memo to Texas Legislature: Grow a pair.

Memo to State's Attorneys across the State of Texas: start doing the job you were elected to and enforce the laws that are on the books.

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.

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.

This doesn't bode well...

...for justice in Asheville. An (unnamed) judge reduced Charles Diez' bail from $500,000 to $200,000 so he could get out of jail. Still no word on if he's still being paid. I have some problems with a culture that looks the other way and allows people to render mayhem with guns on the public at large just because they are "public servants". As alleged, this is a serious crime, and (according to news accounts at least) the facts of the matter do not seem to be much at issue.

Throw the book at this guy. He's proved that he's a menace.

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:

Bike Comics

Bike comic strips and comic books, that is. No stand-up here. Let's visit a couple of modern-day heroes, and one very special superhero from the 70's.

Frazz by Jef Mallet

Frazz, aka Edwin Frazier, is a man for our times. Obviously educated, he is nonetheless underemployed (intentionally, for his backstory is, he's a songwriter who has made it big but can't give up the interactions of his "day job" as a middle-school janitor.) His interests? Education, philosophy, music, the impertinence of youth, and (to no small degree) physical activity, which includes a good deal of bicycling. To his credit, when Frazz is on a bike, he always wears a helmet. If you're lucky enough to have a daily newspaper that carries Frazz, don't pass him by.

I really like Mallet's graphic style. While it is very disciplined, it looks loose and sketchy, almost at times like Bill Watterson. His characterizations (both visual and dialogue-based) are great. I especially like Ms. Olson, who (no doubt unfairly) reminds me of countless teachers of my youth.

Yehuda Moon and the Kickstand Cyclery by Rick Smith

Yehuda Moon, like Frazz, is full of attitude (what practical cyclist isn't?) Yehuda is in the trenches, however. He works in a bike shop (the Kickstand Cyclery) and is a year-round commuter. He lives to ride, and will use any excuse to get on his bike to "run an errand". He seems to lack Frazz's lofty philosophical point of view, though, and the day-to-day of the world gets to him quite a bit more than Frazz. Sometimes the 'tude manifests itself as antipathy to heedless drivers (as in the example above) and sometimes it's just pure stubbornness, as in Yehuda's refusal to wear a bike helmet.

Yehuda Moon is an online-only strip and is subscription supported. Judging from the amount of comments on a strip on any given day, he has a strong readership (and I hope that is reflected in the subscription ranks.) There are a lot of cyclist "insider" jokes in this strip, and casual recreational cyclists might not get all of them. But you know, I've known guys (especially in Austin, Texas, where I used to live) who worked in bike shops who were just like Yehuda Moon.

Sprocketman by Louis Saekow

Sprocketman is a superhero with a single purpose, to see that people are safe on their bikes. He originally appeared in the mid-t0-late 1970's in a comic book that was published and distributed as a joint project of the (California) Department of Public Safety and a nonprofit organization called the Urban Bikeway Design Collaborative. The comic book was drawn by a pre-med student at Stanford named Louis Saekow. It turned out to be a bit of a game-changer for Saekow, as he had so much fun drawing the comic book (his first) that he changed his major from medicine to graphic design!

In late 2002, Stanford University Transportation Services commissioned Saekow to do some more Sprocketman promotions. I'm not sure if they ever intended to do a complete comic book, but if it happened, I haven't been able to locate it. I think I may still have some original Sprockeman comics out in the garage — I used it in a bike commuting class that I taught 'way back in 1979. If you want to see the original Sprocketman comic book, you can download a PDF of it here.

Sprocketman also puts in an appearance in a very quirky website called "Pisser," which stands for "Public Information & Safety Superhero Education Rangers".

Bike to Work [Fill in the Blank]

I attended in mid-May the "Bike to Work Day" held along my morning commute in Columbia, Maryland. It was frankly frustrating, and as probably the only regular cycle commuter in attendance, I felt, frankly, out of place. Who were all these people in colored Spandex, and where did they come from? Unlike last year, when it was a downpour, the weather cooperated, and there was a pretty good crowd of people, I'd say 50 or so. A smattering of the attendees are described below:
  • An older middle-aged woman who steadfastly refused to be convinced that riding with the traffic was safer for her;
  • A group of cyclists who had a 10+ mile commute for which they hadn't figured out the route;
  • A group of bicycle cops, off at a small remove, looking like they didn't belong, and no other cyclists were going over to talk;
  • The usual group of recreational club cyclists waddling around on their racing cleats;
  • Maybe (maybe!) one other person who was outfitted for practical cycling (this was the only other bike with fenders, for God's sake.)
I went off to talk with the cops. They were nice enough guys, if a little clueless about what "bike to work" was all about. I asked them about their training, and they said they had received certification from the International Police Mountain Biking Association, which trains and certifies policemen, EMS, and security people. I asked about the coursework, and they emphasizd the low-speed, crowd-oriented part of the training. (I've since followed up on it, and to me, the PDF coursework summary offered by the IPMBA looks pretty good for a 3 day course.) As usual, I would say, the cops were a little too focused on the hardware. They kept looking at me a little strangely, maybe because I was wearing my "Eclectic Shock" T-shirt (image at right.)

But, getting back to the point. What is the purpose of Bike to Work Day? Is it
  1. To convince people that they can physically manage the ride to and from their place of work? Maybe it does that, but I also suspect that there are enough mishaps (from flat tires, sunburn, and being late to work from simply getting lost) that there is a significant risk that the opposite effect may be achieved.
  2. To allow local politicians to conspicuously ride a bike and thus try and capture the bike riding community as supporters? I suspect that this plays no small role in the planning. For sure, I didn't hear anyone talking about serious new bikeway planning or sharrow painting. (Unlike lucky Boris, see previous post.)
  3. To educate people about safety? There were State of Maryland DOT brochures out about "Bike safety" competent enough I suppose in their content, but they featured a little girl in pigtails on a banana-seated bike as their protagonist, thus perpetuating the image of bicycling as a children's activity.
  4. To ecucate people about what they really need to know about how to commute successfully? In this respect it failed miserably. Success as a cycle commuter requires planning and motivation. Resources promoting either of these were nowhere in evidence.
I suspect the real answer is 2, and so I've become more than a little jaded about bike to work day. I've joined the ranks of Bike Snob NYC who put out a PSA on Bike to Work month. (More and more, I like Bike Snob, even if he does leave me rather breathless.)

Think about it -- even the name is wrong. What does "Bike to Work Day" mean? It should be "Bike to Work Unless It's Bad Weather", or "Bike to Work Year Around". I've come to terms with the fanatical streak that keeps me on my bike and I enjoy the side-benefits, but I must admit I don't have the least practical idea about how to convince others to become regular practical cyclists. That "regular" part is pretty important -- how do you make bike commuting a habit?

Freak Incident for London Mayor

The mayor of London, Boris Johnson, was nearly caught in a totally freaky accident while testing out likely bike routes for infrastructural upgrading. Johnson and an entourage of about 10 cyclists were properly riding on the left edge of the pavement along a street where parked cars were on the right, and an overtaking truck had a rear hatch swing open, catch a parked car, and fling it (!!!) across the road, nearly taking out (in a major way) several of the cyclists. Luckily, no one was injured, but boy howdy, this could have been messy.

The Wharf account of the incident can be read here; The New York Times also has an account here which includes a video taken from a security camera. One of the riders in the group, also has a couple of Flickr photos here.

This incident is such a freaky one that it's difficult to draw "lessons" from it, but here at least are a few observations (feel free to chime in if you have others):
  • The danger here is by no means confined to cyclists; pedestrians or motorists would have been equally at risk;
  • The truck driver was clearly negligent (in not buttoning-up his truck at the very least) and deserves a healthy fine;
  • The system of sidewalk/curb/bike lane/parking lane/driving lane would have greatly ameliorated (if not eliminated) the risk here;
  • Boris Johnson is one lucky guy, as are his fellow riders;
Freaky Friday, indeed.

Bicycle as Fetish

My dictionary defines it thus:
fet•ish |ˈfeti sh |
noun
•an inanimate object worshiped for its supposed magical powers or because it is considered to be inhabited by a spirit.
Now, bear that definition in mind as you read and view this article from the Style (of course!) section of the New York Times, a photo layout of high-fashion models draped over Dutch and high-end American street bicycles. After reading (with no small amount of amusement) this article, I have come to the inescapable conclusion that bicycles are now a fetish in urban America. Since it is defined as bestowing powers, what can we say is the power it might bestow? I submit that the power (in today's America) is coolness.

Bikes have become cool. Partly as a result of Lance, partly as a result of the skinny young bike couriers, partly as a result of the ecological movement, partly as a result of last year's gasoline price bubble, bicycles have arrived.

The fashion models bear witness to this. I mean, really! The set of individuals who would not only bike to work but who would insist on being a fashion plate is very, very small. This is not for societal reasons, it's for practical ones. Let's examine a quote from the Times article:
Can the bicycle, the urban answer to the wild mustang, slow down and put fenders on? Can the urban cyclist, he of the ragtag renegade clothes or shiny spandex, grow up and put on a tie?
I think what's interesting is the way this quote (and the article as a whole) presents this as an either-or. Either spandex or worsted. Either wild or staid. Either adolescent or grown-up. While the either-or is effective as a literary device, I think it's a bit overwrought in this particular case. Let's look at some facts:

"Real" cycle-commuters have to deal with the weather. Even sitting upright on a Dutch bike, in New York City there are probably only about six weeks out of the year (three in spring, three in fall) where you could ride to work a distance of greater than 3 miles and not get either grossly lathered up or pretty darn cold. Fashion cycling is a very limited activity, and people who cycle because they are motivated by fashion-good-looks won't be doing so for very much of the year.

"Real" cycle-commuters have to deal with safety. The Times article states, "Dutch bikes are ridden upright, not hunched over, and you move at a safe, slow gait". Please! Moving at a "slow gait" on the streets of Manhattan is safe? Riding a bike to work, preoccupied with how I'm going to keep my two-thousand dollar Marc Jacobs suit from getting stained or ripped is safe? Not wearing a helmet because "..riding a bike should be normal, and you shouldn’t have to wear a funny Styrofoam hat” is safe?

"Real" cycle-commuters in the City have to deal with New York. The article pays lip service to the ever-present everyday problems of the commuter: the traffic, the fear of theft, the lack of secure bike parking. None of these are made any easier by being dressed fashionably. (Lugging and lifting bikes is a great way to rip tight-fitting pretty-boy suits. I think the look on the face of the model in this picture, dealing with the folding bike, says it all.)

The Times article, in the end, is kind of a mish-mash (or "mashup," the more popular contemporary term). It flits around, and touches on a wide variety of very valid and interesting issues, but doesn't stay with any of them long enough to make sense. Of course, that's not its point. Its point is to sell fashion, which it does admirably with its slide show.

This isn't the first recent intersection of bicycling and fashion that comes to mind. There are the $3000 cycling suits by Rapha, fresh from Savile Row, and the seriously sartorial Dashing Tweeds get-up that bike manufacturer Gary Fisher (right) recently was fitted for in London. The Dashing Tweeds suit is made of Lumatwill, a fabric whose pinstripes are reflective for night riding. Like Gore-tex it's a Teflon laminated fabric, so it's both breathable and waterproof. To me, this is a true bespoke ("custom" for those of you who don't speak the King's English) suit for a cyclist. It's truly forward-looking and (assuming as I must that it's cut for freedom of movement) represents something that could be seriously used by a commuter on those days when he just has to wear a suit.

David Colman of the Times has put up a visually interesting article, but ultimately it's about the conventional fashion trade. It seems ironic to me that there's a true story going on about cycling and cycle-clothing, however, and they're missing it.

PS: Hey, NYTimes, where are the female models? Is it just too hard to reconcile the way that real female cyclists look with the current uber-anorexic female fashion model?

Sharrows

Let's continue on the topic of street marking.

Wanting to know more about sharrows, I went to Wikipedia and read about shared lane marking. (I had to read about a district in Sheffield, England first.) I was a little unclear on the topic, I suppose, as I had thought that sharrows were rather vague in their application. Nothing could be further from the truth, as there appears to be a small if well defined body of traffic standards that apply to shared lane markings.

If you've (like me) not been paying close attention to the sharrows issue, here's a brief definition: Sharrows are "bicycle use" road markings that are installed where complete bike lanes cannot be installed for various reasons including:
  • Not enough cyclists to justify bike lanes;
  • Too expensive to install bike lanes;
  • Use of bike lanes would require loss of parking; and/or
  • Use of bike lanes would require road widening;
The city of San Francisco did a study on sharrows in 2004 that they have published in PDF form. The study's stated goals for sharrows is the following:
  • Improve positioning of both cyclists and motorists on streets without bike lanes;
  • Reduce aggressive motorist behavior;
  • Prevent wrong-way bicycling;
  • Prevent bicycling on sidewalks;
San Francisco additionally studied two different forms of sharrow marking, the "bike in house" design and the "chevron" design. Their study logged 140 hours of videotaping of before-and-after activity on six different streets in SF, three of which were two-lane and three of which were four-lane. Even though this study is not exactly "new news", I must say that I'm impressed with the size, thoroughness and rigor of this study. San Francisco has got a bunch of wonks that know what they're doing, statistically.

So, what happened? Well, the city of San Francisco (CSF) videotaped and analyzed a lot of traffic behavior. In 6 street locations, and before painting the streets, they taped cyclists' positions on the street, motorists' locations, and clearances afforded cyclists by motorists. (They did this for 1100 cyclists.) Then they painted the sharrows with the center of the figure 11'-0" out from the curb. And they ran the video study again. The results of the study are as summarized in the graphic at right.

I don't know about you, but I think these are pretty significant results. Cyclists are clearly less crowded towards parked cars, and motorists are clearly making better affordances for them.

One of the interesting things that the CSF found was that while the "chevron" design eliminated wrong-way cycling where it was used, the "bike-in-house" design appeared to have no effect in this area. For this reason (and the slightly better affordances noted above), the CSF approved the "chevron" design for use on CSF streets.

Because the markings were applied to the streets with no preceding public education program (the CSF evidently felt this might have skewed the results,) cyclists and motorists were then surveyed as to their perception and understanding of the markings. I won't go into the results of this survey in detail, (you can peruse the PDF if you like, as it's all there,) but will hit on some highlights:
  • Most cyclists felt that the markings indicated a bike route;
  • 60% of the cyclists felt an increased sense of safety;
  • 33% of the cyclists felt that the markings caused them to "take the lane" more;
  • 35% of the cyclists felt that the markings improved motorists' behavior;
After reading and reflecting on this excellent study, I feel that I have a much more positive feeling about sharrows than I had before. First and foremost, they are effective; they work to improve cyclist/ motorist interactions. Secondly, they have a "skills improvement" component, that of helping the cyclist attain proper position on the road. Finally, their ambiguity (which had put me off a little before I read the study) may prove to be one of their strong points: while a cyclist may feel he is "unprotected" if he ventures outside a fully-marked bike lane, no such boundary exists or is even implied with a sharrow, and this is probably a good thing.

The Urban Repair Squad

There's an interesting group of urban cyclists in Toronto who are practicing a form of "street art". They call themselves the "Urban Repair Squad", and a website showcasing their work can be found here. The manifesto of the URS goes something like this:

MISSION:

To encourage bicycling as an antidote
to the poison that is car culture.

To invert the status structure of the commons,
returning priority to pedestrians and bicyclists over cars.

To create an infrastructure
that promotes polite sharing of the roadway.

To employ the concept of Critical Mass,
encouraging cyclists to bond together
and more safely take back their rightful place
on the public roadways.

To encourage citizens to reclaim
ownership and stewardship of their public space.

To actively construct a positive future
of what urban transporation could be
by installing it NOW.

Your city is broken.
Don't wait for the bureaucrats to fix it.
DO IT YOURSELF.
So, what doe the Urban Repair Squad do, exactly? They surreptitiously paint bike lanes and sharrows. This is usually done under cover of darkness ("rush hour bike lanes.") Tom Vanderbilt, in his blog, notes that they do this while "disguised as municipal workers." This is an interesting and amusing (if true) twist on the term "street theatre", entertainment not only in the street but in fact changing it. Vanderbilt notes that they have painted over 6kms of bike lanes in Toronto.

If you download and read the URS manual, it outlines (sometime in amusing hand-drawn comics) the process and results of this urban guerrilla activity. I think that, as long as the bike lanes are well-chosen and well-executed, this is a laudable activity, although it raises some potentially difficult questions, e.g. what happens if a cyclist is struck by a motorist while in a guerrilla bike lane? Is the liability of the motorist somehow reduced because of the illegality of this urban infrastructure? (I'm reading a book on the legalties of cycling, which I will post on in the near future, that will hopefully point the way to some answers on this.)

PS. The URS website linked above is claimed to be not an "official" web site. It is maintained by a photographer named Martin Reis who claims to be only a "fan" and documenter of the URS activities and not a participant (sure, Martin, sure! :)

Lawfulness & Licensing (Survey)

Once again, the NY Times has a well-written screed about urban cycling. It's here. I have to say that the sentiments of the author, Robert Sullivan, pretty much mirror mine. Riding in an urban environment carries inescapable risks, and it's simply imperative to avoid the risks we can by obeying the rules of the road. As one of the article commenters (from Davis, CA) responds, "same roads, same rights, same rules".

Sullivan, in the concluding paragraphs of his article, makes four suggestions for "better Bike PR":
  • Stop at intersections;
  • Don't ride on sidewalks;
  • Don't ride against traffic (especially on one-way streets); and
  • Signal your turns;
This is all pretty basic stuff, and I agree that universally doing these things will improve the lives of all urban cyclists (practical and otherwise!) but lately, I've been thinking further afield, deeper about this problem, venturing into what I'm pretty sure will be unpopular territory.

Simply put, the question is this:
If bicycles are vehicles, prone to the rules of the road like cars, and fundamentally unlike pedestrians, should bicycle riders who use public rights-of-way be licensed to operate their vehicles?
With no small amount of trepidation, I'm coming round more and more to the conclusion that we should be licensed. I think this solves two fundamental problems that otherwise show no clear way of being solved. These problems are:
  • Lack of Skills Training: Many, many cyclists on the road are woefully unprepared, both physically and mentally, for dealing with traffic issues. They don't know how to recognize dangerous situations and how to avoid them. Any licensing program would have to have a concomitant skills development and testing program to justify the awarding of licenses.
  • Lack of Moral Hazard: If I'm a driver, and I behave irresponsibly, then my license can be revoked, and I have to cease driving (at least if I want to obey the law). This threat of "points" has a strong effect of keeping my more animal impulses in check.
I look at "outlaw" cyclists, the heedless or reckless ones, and see people who are behaving as though under the influence of a drug. (See this post over at the Momentum website for yet another essay / perspective on this by Deb Greco.) Certainly cycling as an experience can convey a sense of euphoria, and it is the dangerous aspects of this euphoria in a public sphere that vehicular laws are intended to regulate.

The question is, should bicyclists play offense or defense? There are those, uh, "colorful cyclist personalities" who insist on the right to play offense. They assert that in Europe cyclists are treated with far greater deference by motorists, and that's the way it should be here, dammit. I'm a pragmatist, and I believe in defense. Cars are big, hot, massive, dangerous. To assert that it "should be otherwise" is all very well, but it is what it is. Much as I like Europe, much as I've enjoyed cycling over there, the US is different. I say that for me, for here, defense is the game.

So, time for an informal, non-scientific survey. The Blogger system doesn't (at least as far as I have discovered) allow for a formalized survey system, so let's do an informal one. If you have read this far, please do me the favor of commenting on this blog post with a letter signifying one of the following survey preferences. Honor code, here; don't be casting multiple votes (I'm pretty sure I can delete multiple votes after the fact, anyway.) As I've implied above, this is primarily aimed as the US, so if you're voting from overseas, it would be helpful for you to say where you're located. Feel free to comment further, but start out your comment with one of the letters A through D:

Question: Should bicycle riders who use public rights-of-way be licensed to operate their vehicles?
  • A. Yes; time to get serious; Particularly as the number of cyclists grow, it will make the roads safer for all of us.
  • B. Partly; Require licensing for bicyclists using roads that have speed limits >= 30 mph. This will allow "family use" in suburban 25 mph zones.
  • C. No; If we provide bike lanes, the safety problem will go away, except for those idiots who want to take crazy risks with their own necks.
  • D. Hell, No; I demand the right to do as I please on a bike; I'm not a car and I shouldn't have to behave like one. We need the government out of our lives.

Bike Safety Tips...

...from The Onion, from 2001. Here. This post is definitely showing its age (I mean, a lot of trends have come and gone in eight years!) but I love the Onion. It's a guilty pleasure. I especially like the advice,
Bike safety can never be stressed enough. If you doubt this, try stressing it as much as you possibly can. It won't be enough–guaranteed.
Go for a quick laugh.

Hazards 1: Traffic Calming: Chicanes

Anyone who's done cycling in an urban environment has encountered traffic calming devices. On my modest 9-mile commute in Columbia, MD, I experience speed bumps, rumble strips, chicanes, and traffic circles. Sometimes these devices don't work entirely as intended; they can be abused by drivers, or can be confusing to drivers who don't know how to manage multiple inputs (Bicyclist ahead! Traffic calming ahead!) in a way that reconciles everything.

Sometimes, as a Practical Cyclist, you've got to help that driver Do The Right Thing.

Today we'll talk about chicanes, "pinch points" that are intended to slow down traffic. A two-way chicane is illustrated at right. Notice that I've illustrated a chicane that preserves the shoulder / bike lane. Not all of them do.

So, what's the problem here? Well, the simple problem is that most drivers dislike (sometimes intensely) traffic calming and therefore feel entitled to "cheat" it. ("Let's see if I can get through this chicane without slowing down. Wheee!") And sometimes they tend to ignore little things like, oh say, that cyclist up ahead. I've heard other city cyclists complain about this bitterly, and yet I've not had a bad problem with this. Maybe 1 in 100 times, I'll have a jerk motorist squeeze by me, but it's rare.

What's my secret? The magic of Eye Contact. I'll be the first to say that I don't know why eye contact works, but it definitely does. What I do is, when I'm approaching a chicane and I hear a motorist behind me, I'll turn and fix an eyeball on him when he's about 3 or so car-lengths back. In (as I say) 99 out of 100 cases, it works like a charm, and that hundredth case, well, I take evasive action (and usually holler something.)

Try this the next time you come upon a pinch point (and 3-way traffic circles are analogous to chicanes in this context). You'll be surprised how effective it is.
