Some perspective on Perspective…

Here’s what I think is really important about this video in itself and as an example: it applies modern promotional and media techniques to put across the message of cyclist integration into the normal traffic mix. We who advocate that need to do a lot more like this. The paint and path crowd regularly uses those techniques — and goes further, using thought-terminating clichés, pandering to popular misconceptions and twisting the meanings of words, while we too often get tied up with technical details.

On the other hand, I think that it is possible and useful to expose the intellectual bankruptcy of the PnP promotions — I’m thinking particularly of some bike box promotions I’ve seen. Oh, how I especially savor the one with Legos from Calgary which intones “same rights, same rules” while showing different rights and different rules…how Orwellian…or the one from Tallahassee with a green box sliding along a sidewalk, and a sound track repeating the incantation “bike box” so as to drum that expression into the mind of the public…

A reply to comments on my previous post…

In a comment on my previous post, Khal Spencer asked whether the extension of a bike lane in a bike box is in fact a lane, or whether on the other hand, the bike box is more like a crosswalk. Let’s have a closer look at that issue.

If we consider the bike box to be like a crosswalk, rather than the part which continues the bike lane to be a lane, then pedestrian rules should in theory apply. In section 11-502 of the Uniform Vehicle code, I read:

(b) No pedestrian shall suddenly leave a curb or other place of safety and walk or run into the path of a vehicle which is so close as
to constitute an immediate hazard.

Massachusetts state law establishes rules for motorists at crosswalks but doesn’t have a rule for pedestrians — one of the many gaps in our law, which was never conformed to the Uniform Vehicle Code. Code of Massachusetts Regulations 720, established by the Highway Department (now part of MassDOT) fills in the omission, but only applies to state highways. I can just imagine the officials at the Highway Department taking a look at the state law, maybe proposing revisions which the legislature didn’t pass, and then promulgating this regulation, with the intent, “not on our watch!”

9.09 (4) Pedestrian Crossings and Use of Roadways.

(a) No pedestrian shall suddenly leave a sidewalk or safety island and walk or run into the path of a vehicle which is so close that it is impossible for the driver to yield the right of way.

On the other hand, in case we don’t consider the bike box to be a crosswalk, the regulations state

9.09 (5)

Crossing at Non-Signalized Locations. Every pedestrian crossing a roadway in an urban area at any point other than within a marked crosswalk shall yield the right of way to all vehicles upon the roadway. At a point where a pedestrian tunnel or overpass has been provided, pedestrians shall cross the roadway only by the proper use of the tunnel or overpass.

These rules for pedestrians are the closest Massachusetts has to a law which applies to the bike box. There is no law which applies specifically to the bicyclist’s swerving into a bike box, People who promote bike boxes in the USA don’t concern themselves with establishing a legal framework for them. In any context affecting public safety and which draws appropriate intellectual scrutiny, this would be regarded as wanton recklessness, but bicycling doesn’t draw that scrutiny. The law, to the degree these people concern themselves with it at all, is a problem. “The law is for cars,” — most usually, an excuse for noncompliance by individuals, extended to a license for installations which also pay no regard to law. We aren’t talking about the honored tradition of civil disobedience here, we are talking about opportunistic bicycle operation, sometimes in reasonable ways, such as failing to come to a foot-down stop at a stop sign, sometimes in more important and perilous ways, such as overtaking unsafely on the right. Thsi opportunism expands its scope into disregard for the law by government itself. The installations come first, and changes in the law can wait till later once the installations are a fait accompli. I have discussed this same issue before, in connection with some “Yield to Bikes” signs which Cambridge has installed. Laws to accommodate unsafe movements will consist of reduced burdens of proof and increased penalties for motorists, for colliding with defenseless cyclists — in installations which have rendered the cyclists defenseless, where only the motorist can prevent a collision — and can only prevent it using extreme caution.

Boston Globe: Reality Check Time

The caption with the picture below in the Starts and Stops column of the Metro section of the June 17, 2012 Boston Globe reads:

Cyclists stopped for a red light in the “bike box” on Commonwealth Avenue in the Back Bay. They provide the cyclist a safe space to wait ahead of cars at traffic signals.

Photo which appeared in the Boston Globe Metro section, June 9, 2012

Photo which appeared in the Boston Globe Metro section, June 9, 2012

(The Globe story may be behind a paywall, but you can probably access it through a public library’s Web site using your library card number.)

The smiling cyclists show that this is a posed photo; the photographer evidently only thought of the large puddle in the foreground as an artistic touch. How about the car encroaching into the bike box in the background?

Well, yes, OK, waiting in the bike box might be safe — drivers are unlikely to encroach on a cyclist who is already waiting in the bike box. The problem is with getting into the bike box. The Globe columnist, Eric Moskowitz, never considered that bicyclists approaching the bike box on a red light are encouraged to swerve sharply left across multiple lanes of motor vehicles, with no way to know when the light will turn green. A waiting motorist will not see the swerving cyclist if looking to the left for traffic at the wrong moment. A tall vehicle in one lane will conceal the cyclist from a driver waiting in the next lane.

Portland, Oregon has hosted a study of bike boxes, which found that this is actually a rare problem in Portland, because cyclists are smart enough not to swerve into the bike box. Instead, if the light is red, they wait at the right curb, blocking other cyclists behind them. I saw the same thing on Commonwealth Avenue. As I said before, the Globe photo is posed.

But on the green light, there’s another problem. Bike boxes and the bike lanes which lead to them invite cyclists to overtake waiting motor vehicles on the right, risking getting struck by a right-turning vehicle. A bicyclist was right-hooked and killed in Portland, Oregon, on May 16, 2012 but apparently that news didn’t reach the Globe’s columnist, or didn’t make an impression on him. Now a letter from the City of Portland is conceding that car-bike crashes have increased at some of the intersections where bike boxes were installed. So much for the Globe’s assertion of safety.

Conscientious bicycling advocates have been warning about the “right hook” problem for decades, based on the difficulty which motorists have in looking into their right rear blindspot, while also checking the intersection ahead.

Swerving across is illegal too: here’s the Massachusetts law, in Chapter 89, Section 4A. It applies to bicyclists, the same as other drivers. Every state has a similar law.

When any way has been divided into lanes, the driver of a vehicle shall so drive that the vehicle shall be entirely within a single lane, and he shall not move from the lane in which he is driving until he has first ascertained if such movement can be made with safety.

Bicycling advocates, planners and government officials who promote bike boxes have simply chosen to pretend that this traffic law doesn’t exist, or can be ignored. Same for the limits of human abilities.

Now, I wouldn’t be fair in making this criticism if I didn’t suggest alternatives.

The one I favor is for cyclists to merge before reaching the intersection. That can be facilitated by signal timing at the previous intersection to allow cyclists to merge across when motor traffic is stopped, and a clear lane into which to merge.

Other suggestions have been to prohibit right turns, or to install special signals to warn cyclists that the light is about to change. Denver’s retired bicycle coordinator, James Mackay, has described some of the measures used in European cities.

These measures will, however, result in more delay, for both cyclists and motorists.

It may be more practical just to designate another street as the one for through bicycle traffic, My favorite suggestion at this Back Bay location would be Newbury street, configured as a two-way bicycle boulevard with a bridge over the Muddy River to connect it with the Fenway area.

North-south, east-west: is that best?

The Facebook Cyclists are Drivers group carries a report of a cyclist who was rear-ended by a motorist who was blinded by the setting sun. And, here’s an urban planning issue I bet that you haven’t heard about (unless you have read my Facebook comment on that report). The solution to this problem is, well, blindingly clear, but also, completely overlooked.

Why do street grids have to go north-south and east-west, guaranteeing that the east-west streets will have blinding sun for a week or two, twice a year, early morning and evening peak commute time, and that the south side of those streets will only get sun in the late spring and early summer, early and late in the day?

If the street grids go northeast-southwest and southwest-northeast, then both sides of every street get sunlight every day of the year, and are more conducive to snow melting and plantings thriving. There is never blinding sun along any street (though there can be when turning at intersections — this issue, to be sure, deserves further study).

This approach works except at far northern and southern latitudes, where the sun rises and sets far north or south of the east-west line in midsummer and midwinter.

One city which in fact has a northeast-southwest and northwest-southeast street grid is Montreal, because the long axis of the Montreal island runs northeast-southwest. That’s one more reason, though not the main one, to discredit the Lusk et al. study of Montreal bikeways 😉

In the USA, the east-west-north-south blinding glare problem was given a major boost by the Homestead Act of 1862, which laid out most of the Midwest and Great Plans, both urban and rural, as far west as the Rocky mountains, in north-south-east-west grids.

The late Prof. John Finley Scott, a staunch advocate of integrated cycling, proposed “wrecking ball therapy” as a way to cure the problems with aging urban infrastructure, and perhaps this is an improvement to keep in mind in that context.

Cycle track mania on the slippery slope in Somerville, Massachusetts

My attention recently was drawn to a proposed project for Beacon Street in Somerville Massachusetts, a couple of towns away from where I live..

A presentation from a public meeting is online here:

https://docs.google.com/file/d/0B1Y_jIpLYtpycEZNOUVTNUYxQVU/edit

(I was unfortunately not able to attend the public meeting last night (November 13), so I can’t provide any comments about it.)

This project would narrow the roadway between Oxford Street and the Cambridge city line, removing parking on one side of the street and installing cycle tracks in the some sections, and reinstalling bike lanes in others. The proposal would narrow the street by moving curbs, making it expensive to install and expensive to revise or remove.

There has been pushback from a residents’ association on the issue of parking removal, though without any discussion of bicycling issues, here:

http://beaconstreetsomerville.org/reconstruction-project-resources/beacon-street-parking-study/

As a bicycling advocate, I support the removal of parking (probably requiring substitute parking though to bring residents on board with the project), but I want to see a bicycling treatment that works.

The proposed cycle tracks, at sidewalk level, are seriously inappropriate here on a sloping segment with heavy bicycle commuter traffic and crossed by dozens of driveways, in a residential area where there is heavy pedestrian traffic and where children will wander around and play. The usual arguments about making bicycling attractive to women and children have been put forward, but the proposed reconstruction is best described as creating an attractive nuisance. Bicycle commuters are not going to slow down to a safe 8 miles per hour riding down the hill on Beacon Street, and that is going to be a problem. On the uphill side, where parking will remain, bicyclists will have been moved from the door zone on the street side to the door zone and walk-to-car crossing zone on the sidewalk side. Bicyclists will be subject to harassment for riding on the narrowed roadway.

Snow and ice removal will be a problem in winter — the cycle track will be where snow gets dumped from the street, creating a barrier and preventing water from draining.

The proposal for the segment with bike lanes is just as bizarre, failing to take advantage of the removal of parking to move bike lanes out of the door zone — but instead narrowing the roadway so that bike lanes can be reinstalled in the door zone.

Beacon Street isn’t wide enough for parking on both sides, while comfortably accommodating bidirectional motor traffic and bidirectional bicycle traffic, Removing parking on one side could resolve that issue. My preference for the entire length of the project would be to take advantage of removal of parking to accommodate bicyclists outside the door zone on the roadway, and throw in a bit of traffic calming to slow motorists..

I note that a rail-with-trail in the Fitchburg line corridor, which is nearby and nearly parallel, also has been proposed, and would offer an option for bicyclists who are not comfortable riding on an arterial street.

Also see this later post which I wrote after attending a public meeting and which describes details of the city’s plans, with illustrations.

The slow race

I have my antennas tuned to the signals coming from the paint and path, anti-car, transportation reform segment of bicycling advocacy. I have no access to the messages which advocates of this stripe send to one another. But when I hear the same suggestions coming from multiple sources, I must conclude that there is communication among them.

Here’s the latest party line: bicycling will be better for us when we all ride very slowly. And we should not bother with helmets, because bicycling will become safer if we don’t.

I read it yesterday on an urban planning e-mail list in the following words: “The question … is one of helmets for all versus just riding a bicycle safely…I prefer seeing women, men and kids riding in safe environments en-mass [sic] which will then slow speeds and make bicycling in the city what we see in Amsterdam and Copenhagen and what we still see in China in many locations.”

I heard it again today on Robin Young’s Here and Now radio show on NPR. At the beginning of the show, host Young announced that a topic would be “is it possible that not wearing helmets makes bicycling safer?” The helmet segment consisted entirely of an interview with a guest Elizabeth Rosenthal, a public-health advocate. Here’s a link to the show segment: http://hereandnow.wbur.org/2012/10/02/lose-bike-helmets

The claim which underlies the party-line argument against helmet use is that if people don’t have to wear a helmet, then more people will ride bicycles, motorists will become more attentive, bicyclists will have to go slower (because there will be so many getting in each other’s way on narrow bicycle paths, also part of the plan, though that isn’t mentioned). Voilà, bicycling will be safer. There also is a health claim.

Let’s consider a parallel example: “is it possible that not wearing a lifejacket makes canoeing safer?” And here is the supposed logic, as applied to canoeing: if people aren’t encumbered with having to purchase and wear a lifejacket, then masses of people will take up canoeing, people in powerboats will be more attentive about avoiding collisions with canoes, and the rivers will be clogged, forcing slowdowns — and so canoeing will become safer. Also, the health benefits of canoeing to society at large will outweigh the losses through drowning, even if (also never mentioned) most people never canoe far enough or paddle hard enough to get a meaningful fitness benefit.

The argument as it applies to bicycling has some traction because it rests on a nearly universal, distorted perception of risk — fearmongering turned inside out. I took canoeing as an example because it is well-known that most canoeing incidents do not involve powerboats: a canoe simply capsizes, or someone falls overboard. Less well-known is that over 70% of injury-producing bicycle crashes do not involve a motor vehicle. Also in incidents which do involve a motor vehicle, a helmet often prevents or mitigates injury.

What underlies the anti-helmet drive is social engineering by the bicycle industry, environmentalists, transportation reform interests and public-health advocates like Young’s guest Rosenthal, to recruit more people to ride bicycles — and mitigation of risk to the individual bicyclist be damned. We prime the pump for increased bicycle use by shoving that issue under the rug, and if we have a few fatalities and disabling injuries (actually, many thousands –) which could have been avoided, well, these are sacrifices that must be accepted in the interest of the Greater Good.

The anti-helmet argument gains more support thanks to the advent of municipal bike-share systems, which at the same time make access to a bicycle easier and use of a helmet more inconvenient.

Also, the story on Here and Now confused the issue of mandatory helmet laws with the issue of personal choice as to whether to wear a helmet. Let me make it clear: I don’t support mandatory helmet laws, which aren’t enforced, yet which can impose a presumption of negligence on a bicyclist who doesn’t wear a helmet — as in “yes, the driver ran the stop sign, but you weren’t wearing a helmet, so you don’t collect on the driver’s insurance.” That kind of blaming the victim is despicable, but it happens. On the other hand, because I care about my own well-being and that of my family, I wear a helmet. I recommend that other bicyclists make the same choice.

“It’s more like walking than riding a bicycle. You’re more like a pedestrian,” said Rosenthal of ideal urban cycling as she envisions it. “The kind of crashes in which people fall off bikes and hurt their heads are really, really, really rare because you’re riding around at 5 miles per hour. It’s more like walking,” said Rosenthal. Great. That’ll get me home in two hours. And who will point out the bicycling is several times as efficient as walking? Taking Rosenthal’s argument to its logical conclusion, I’d benefit more from walking, and then it would only take me four hours to get home. Canoeing upstream on the meandering Charles River from Boston to my home would be even better, and swimming, better yet.

Let me also point out that the speed at which the head strikes the ground depends on head height, not forward speed — and that slow-speed crashes are often caused by collisions while in crowds of bicyclists.

At the end of the radio segment, host Robin Young quoted someone as saying about a helmet wearer, “you’re a racer. Get off city streets.” A competent and fit urban cyclist is by definition a racer? A bicyclist is going too fast, not even as fast as a motor scooter rider, and so should get off the street? Serious confusion reigned.

Bicycling advocacy has always been subject to push and pull from various non-bicycling interests. Now, more than ever, it is being taken over by people, whether with the best of intentions, intent only on personal gain, or who consider themselves to be doing well by doing good — for whom bicyclists are only a mass, a population — as described in one of the quotes at the start of this article. After the US Civil War, there was a name for such people: carpetbaggers. People who might not be familiar with the legacy these people left both for the Southerners whose lot they claimed to advance and those whose tradition they attempted to overthrow might read this: http://en.wikipedia.org/wiki/Carpetbagger.

Danish story, video and comments on the Albertslund-Copenhagen “bicycle superhighway”

A reader pointed me to a news story on the politiken.dk blog about the Copenhagen/Albertslund “bicycle superhighway” which is getting attention and publicity. The reader’s comments on my previous post read:

Yeah, its kind of joke, but to be fair they are not called superhighways in Danish but Super bicycle tracks, and even then most agree that they are not really that super. There is a video of the entire route here if you scroll down a bit [Note: the video is no longer embedded in the Politiker story, but it is online in a Huffington Post story].

http://politiken.dk/debat/skrivdebat/ECE1615543/er-koebenhavns-nye-cykelsti-virkeligsuper/

[New URL for article.]

The two next ones which will open are another story though, as they mostly have their own right of way, and use viaducts or bridges to cross streets.

So, better things may be on their way, but…I ran the article through the Google translator, and it appears in the link below in (sort of) English. The page used to include includes the sped-up video of the entire route.

http://translate.google.com/translate?sl=auto&tl=en&js=n&prev=_t&hl=en&ie=UTF-8&layout=2&eotf=1&u=http%3A%2F%2Fpolitiken.dk%2Fdebat%2Fskrivdebat%2FECE1615543%2Fer-koebenhavns-nye-cykelsti-virkelig-super%2F&act=url

[Again, I link to the article with the video, which I had previously embedded here.]

The one unifying factor of this route is an orange line painted lengthwise to identify it. The first part of the route is relatively tame. Barriers, unprotected intersections and other hazards pile up near the end.

Some representative quotes (I’ve translated from Googlish to English, thanks to an online dictionary and my knowledge of the neighbor language, German.):

From the article:

“I did not expect that I just had to detour on ordinary roads in residential neighborhoods. I did not see much of the green wave that is supposed to be in town. I do not think you can call it a super bike path,” the [politiken dk test rider] concluded.

From comments on the article:

– The section of tunnel under Motorring 3 is dark and miserably lighted. There are many riding schools (which, incidentally, should be forced to close and move out into a rural area!). The tunnel is usually filled with horse s***, and because you can not see in these tunnels due to poor lighting, you can only hope that you do not ride through any of it.

*****

– In the westbound direction, at the pitch-dark tunnels, you have to negotiate two sets of barriers. The point of these, other than to impede traffic, I do not know. But when you have to use all your mental energy to get through these, they constitute more of a hazard than a safety precaution.

*****

I have commuted between Roskilde and the northwest part of Copenhagen 2-3 times a week on a recumbent trike with an electric assist motor for 6 months (https://ing.dk/blogs/pedalbilen). When I used the “super path” the trip was about 3 km and 15 minutes longer. Especially the part of the route in Albertslund is very indirect and inconvenient. There are detours, barriers and ramps in most places, and it will for example not be possible to ride in a velomobile, as far as I can judge. The new route is comfortable and free of exhaust, but as commuter route it gets a failing grade compared with Roskildevej [a parallel, 4-lane divided but not limited-access highway with one-way sidepaths].

*****

– I didn’t see anything which shows that cyclists have priority over the other traffic. Unfortunately, the only thing new that I see is approximately 100 meters of new asphalt in two places near Rødovre, so that it is easy going. There are simply no real improvements for cyclists in relation to other road users! You can still find barriers, sharp turns, bumps and traffic lights. Why is there no new cycle path, e.g. along the western forest road, so you do not have to drive through neighborhoods with pedestrians and children playing? Why are barriers not turned 90 degrees, so users of the route have right of way?

Even if there were brand new asphalt on the entire route, it would never merit the title “super”. Only when a route enables more or less continuous travel at high average speed (which motorists know from motorways) does it, in my opinion, deserve the massive marketing it is currently getting.

*****

…Bus passengers cross the bikeway. It seems quite unreasonable that there are no islands at bus stops where passengers have to wait when they get on and off. Thus cyclists must stop, and so, so much for the “super bike path”.

Copenhagen “bicycle superhighways” have traffic lights, driveway crossings…

A story ran on the program NPR (National Public Radio) Weekend Edition Saturday on September 1, 2012 about “bicycle superhighways” being constructed between Copenhagen and its suburbs. The NPR piece, with comments, is online as text with photos, here:

http://www.npr.org/2012/09/01/160386904/in-bike-friendly-copenhagen-highways-for-cyclists.

Audio is online, linked from the Web page.

As a bicycling advocate, I am looking for useful answers as to what works for bicyclists, based on accurate descriptions. In this NPR report, as in many others, the new bicycle routes between Copenhagen’s suburbs and the city are described as “bicycle superhighways”. But — the article tripped over itself when the reporter described waiting at traffic lights. Superhighways don’t have traffic lights, they have interchanges with grade separations.

NPR reporter Eleanor Beardsley holds a handrail on what is described as a “bicycle superhighway.” in Copenhagen, Denmark.

The caption to this photo on the NPR site reads:

NPR reporter Eleanor Beardsley rides in one of the new bike lanes in Copenhagen. The city is building more than two dozen lanes from the suburbs into the city. They cater to cyclists by including such things as rails and footrests at stoplights.

The photo and caption add even more confusion. This is no bicycle superhighway. Not only is it clear that there must be a stoplight, but the photo shows a lane shared with motor vehicles. Ms. Beardsley evidently doesn’t know the difference between a bike lane and a shared lane.

Another photo with the online article shows a stretch of a separate bikeway in an urban setting:

A bikeway in Copenhagen described as “high-speed” — from the NPR article.

This is a stock photo, credited:

Slim Allagui/AFP/Getty Images

The caption to this photo on the NPR site reads:

Many Copenhagen residents already travel by bike, and now the city is building high-speed routes designed to encourage commuters even in the outlying suburbs.

This is a wide bikeway, but several features suggest that high speed isn’t the norm here. Two of the three cyclists are pedaling on the arches of their feet. There is a pedestrian standing in the bikeway. Bicycles are parked along its side where the cyclists would have to get off and walk along or across it to reach any useful destination.

On the other hand, a map of the Copenhagen suburb of Albertslund, mentioned as the terminus of the first “bicycle superhighway” constructed, shows a rail corridor which might support a bikeway with few street crossings. In the Google map below, the rail line runs from west to east into Copenhagen.


View Larger Map

A close look at the railroad corridor in Google’s Street View shows no bikeway, but on the other hand, the major east-west highway has one-way bicycle (and motor scooter) sidepaths, as shown below:


View Larger Map

The Google map and photo probably predate the new installation, though.

A New York Times article,

http://www.nytimes.com/2012/07/18/world/europe/in-denmark-pedaling-to-work-on-a-superhighway.html?pagewanted=all

is somewhat more informative than the NPR story, indicating that the bikeway is really more a bicycle path than a superhighway, and that it has relatively few intersections with roads. So, we’re still trying to find it.

A story from the Danish authorities is even more informative:

http://www.cycling-embassy.dk/2012/06/06/cycle-super-highways-to-generate-more-cyclists-in-greater-copenhagen-area/

The Treehugger blog even has a very small map (and a link to a video which is unfortunately no longer available available in a Huffington Post article:

http://www.treehugger.com/bikes/what-its-ride-denmarks-bicycle-superhighway-video.html

A Danish government site makes it clear that this route and others like it were assembled mostly by stringing together and upgrading existing bicycle routes.

http://www.cykelsuperstier.dk/concept

The most informative set of pictures is here:

http://www.demotix.com/news/1353441/bicycle-superhighways-and-green-bicycle-path-systems-copenhagen#slide-1

[Archived page is available but photos appear not to be.]

I would like to check out these bikeways so I could know more, but based on the stories, I might ask:

  • How do these “superhighways” differ from what we call bicycle paths, or shared roadways, here in the USA?
  • What is the effect of the traffic lights on travel time?
  • Are there intersections where conflicts with cross traffic are not signal-controlled?
  • What is the carrying capacity?
  • How well is the wide range of level-ground speeds of bicyclists (8 mph to 25 mph) accommodated so the slower ones don’t hold back the faster? (At least, the Copenhagen region is very flat, so speed issues due to terrain aren’t much of an issue.)

All in all, based on what information I can glean from the news reports, the Danish “bicycle superhighway” doesn’t appear to me to be either as direct or as consistent in quality as many American shared-use paths!

This post is a revised and expanded version of comments I posted on the NPR Web site. I do thank NPR for the opportunity to comment, and for the clarification — even if only tangential — about whether the new bike routes are really superhighways .

The other stories provide all too little information. The “superhighway” description, the one I have heard everywhere, is hype, as all too usual with promotion of bicycle facilities, and the Danish Web page shows that the hype in this case originated with the Danish government. This has been a post about that issue, but also about quality of reporting and the lamentable difficulty of obtaining good, useful information about bicycling infrastructure projects..

Some observations about bike-share bikes

I recently spent several hours riding in Montreal with a companion who was using the Bixi bike-share bicycles. These are similar if not identical to others being deployed in North American cities. I have some experience riding a Hubway bicycle in Boston, too.

These bicycles are designed to meet different requirements, compared with a rider-owned bicycle. A few observations:

  • The user is relieved of the burden of servicing the bicycles. That is advantageous– there are no worries about flat tires or other mechanical problems. If a bicycle becomes unrideable, you walk it to the nearest rental stand and trade it for another. A related advantage, especially for city dwellers, is that there is no need to store or secure one’s own bicycle.
  • The bicycles are rugged, and so they are heavy.
  • The three-speed hubs are not overgeared, like those on classic three-speed bicycles. The top gear is about right for level-ground cruising. These bicycles climb better than the classic three-speed in the lower gears, but still, the limited gear range and weight of the bicycle make it unsuitable for steep climbs except when using the “two-foot gear” (that is: get off and walk). My companion found one Bixi bicycle with a Shimano 7-speed hub, which he used for part of our ride, but never found another despite looking for one among several dozens waiting at rental stands.
  • The bicycles have fenders, integral lights powered by a generator in the front hub, and a (front) baggage rack, all features necessary for practical transportation use. Additional baggage capacity would be nice but would require a rear rack.
  • The very low step-through frames and skirt guards either side of the rear wheel allow a person to straddle one of these bicycles even if hardly able to left a foot off the ground, and to ride in an ankle-length skirt.
  • The skirt guards carry advertising logos — a reminder that the bike-share (actually, bike-rental) program doesn’t pay for itself.
  • Many features of the bicycles are designed specifically to prevent vandalism and theft. Wheels are not removable using conventional tools, tire valves are not accessible, the seatpost cannot be pulled all the way out etc. Some of the anti-theft features come at the expense of performance…
  • My companion found that the seatposts on most of these bicycles could not be extended far enough for full leg extension, though he is a full 5’7″ (170
    cm) tall.
  • All the bicycles have flat pedals. If you prefer clip-in pedals or toe clips and straps, you’ll have to ride your own bicycle.
  • The street-tread MTB tires are inflated rock-hard. Evidently, protecting the rims rates higher than rider comfort.
  • Hub brakes — Shimano Rollerbrakes front and rear — allow rims to be out of alignment without affecting braking, but these brakes are weak. The front brake appears to have a power limiter, or else it is mismatched to the brake lever. Braking appears to reach a limit which does not increase, no matter how hard the lever is pulled. (I hope to do a braking distance test soon).
  • The black, padded saddles get uncomfortably hot sitting in the sun on a summer day.
  • The system recommends helmet use but doesn’t supply helmets. Boston is, as I understand, working on an automated helmet dispenser.
  • In both Boston and Montreal, rental stands are consistently placed in the street with the rear of the bicycle facing out into the street. Some are on busy streets. You must walk in the street and back the bicycle out into the street to disengage it from its dock. In many cases, the rental stand is on a one-way street or a street with a median, so the user must walk in the street or ride opposite the legal direction of traffic to get to the through street or bikeway which it services. Usually, one-way streets lead away from the serviced street, and so the travel opposite traffic is almost always at the start of the trip.
  • A user has to to walk to and from rental stands, same as bus stops. The bicycles don’t come with locks except to lock them to the rental stands. If you stop in mid-trip to have lunch or so shopping, you must bring your own lock, and the rental clock keeps running.
  • The Montreal system offers a 24-hour pass, but extra charges accrue for any bicycle that is kept in use for more than 1/2 hour. At cycle-track speeds while obeying traffic signals, that was good for 4 miles (6 km) or less. My companion would note where a rental stand was at the right distance to switch bicycles just short of the half-hour limit. The system made him wait two minutes before he could release another bicycle at the same rental stand. Even one minute over the 1/2 hour adds a charge of $1.75 for the next half-hour. The payment plan, then, provides a strong economic disincentive against longer trips.
  • Walk time seriously increases trip time beyond what it would be with the user’s own bicycle. On average, depending on distance of the start and end of the trip from the rental stand, the time overhead for a ride on one’s own bicycle is less even if it involves donning/removing special bicycling shoes, bicycle gloves and a helmet. There also is some uncertainty whether a bicycle will be available to start a trip, and whether there will be an empty space for docking at the end of a trip. Nonetheless, the program is popular.

I note that the on-street separated bikeways in Montreal have a speed limit of 20 km/h (12 mph). That is more or less what these bicycles are designed for. People riding their own bicycles commonly go faster. The design of the bike-share bicycles goes very much in the opposite direction from the racing spec hype that dominates the recreational cycling market.

All in all: when you ride one of these bicycles, you have been recruited into the bike mode share increase army. It’s like eating army food, which will fill your stomach but which is missing some of the nicer qualities of fancy cuisine or good home cooking. Or like sleeping in an army cot, which doesn’t quite compare with a bed in a fancy hotel, or your own bed at home. But then, an army provides for its soldiers, with a couple of tradeoffs, to be sure — the cost borne by the public at large, and the risk factor for soldiers.

Bike-share programs are structured as a public utility, as a form of public transit. The bicycles are requisitioned outside the usual stream of commerce of the bicycle retail industry. Whether the general sentiment in that industry is “a riding tide lifts all bikes” or that the competition is unfair, I don’t know. I did address that issue in an article I wrote for the sheldonbrown.com Web site on April 1, 2012 — please take note of that date when evaluating my article.

The Photoshop School of Traffic Engineering strikes again!

The Photoshop School of Traffic Engineering strikes again, this time in Minneapolis.

For background, please read the Minneapolis blog post: http://www.ouruptown.com/2012/08/potential-cycle-track-coming-to-36th-street

Also please read John Schubert’s comment on that post.

I’ve added a comment too — still in moderation as I write this, and I repeat the comment here, slightly edited and with this introduction.

The location described in the blog post, 36th Street at Dupont Avenue, is shown in the Google map below. If the full image doesn’t appear, clicking to refresh the page will probably fix that. The image is zoomable and draggable, but by clicking on “View Larger Map”, you may enlarge it, look down from different overhead angles, and switch in and out of Google Street View.

36th Street is part of a grid system. Smaller, lightly-traveled 35th Street is one of several that could instead be configured as a bicycle boulevard (also called neighborhood greenway) like those in Berkeley, Eugene, Portland and Seattle, so bicyclists use the street as a through route while only slow, local motor traffic uses it. That is popular with residents and avoids the problems with sight lines which John Schubert has described.

Now for some comments on the pictures in the Minneapolis blog post. They are examples of of what I call the “Photoshop School of Traffic Engineering”, Or the “Anything Goes” school. Well, anything goes in a Photoshopped picture but not necessarily in reality.

Here’s the first picture from the blog post:

The caption for this photo in the blog post reads “[a] possible cycle track is being considered for 36th Street in Minneapolis.” As we’ll see though, the rendering in the picture is hardly possible.

In the picture, there’s already a sidewalk on both sides but now also a special lane so pedestrians can walk in the street. To make room for this and the bikeway, the blue car in the right-hand travel lane is squished to about 3 feet wide and that lane is about 8 feet wide. The text describes the bikeway as 10 feet wide, but it measures as about 12 feet wide based on the size of the bicycle wheels. 36th Street has a cross street every 300 feet, also entrances to back alleys and driveways in almost every block, but the picture shows maybe one intersection (note crosswalk lines) in the distant background. That is unreal. There’s some need for people to get in and out of all those cross streets, alleys and driveways.

Now, the other picture:

The caption in the blog post reads “[a] rendering of how a cycle track on 36th Street could look east of Dupont Avenue in Minneapolis.” Again, no, it couldn’t.

The bikeway is shown at a more realistic width. I’m not sure though how three travel lanes, a parking lane, 3-foot buffer and 10-foot-wide bikeway fit into a street which now has only two travel lanes and two parking lanes. Also note the car about to turn right across a lane of traffic and then across the bikeway at the one intersection shown. The lane with the closest car in it is shown as a lane of traffic, not a parking lane, or there would be signs and markings to indicate that. Assuming though that it is a parking lane and the turning car isn’t cutting off the closer one, then the closer one is still hiding approaching bicyclists from the turning one, whose driver must look to the right rear to see them as they get closer — remember, they may be traveling at speeds up to 25 miles per hour. The bikeway is outside the field of view of the turning driver’s right-hand rear view mirror. Some vehicles have no windows behind the front seat, and so the bikeway would be in a complete blind spot. I just got back from Montreal where I rode bikeways like this and it’s hair-raising with heavy two-way bicycle traffic in such a narrow space. I also had repeated conflicts with motorists turning across my path, using intimidation to try to make a gap for themselves in the stream of bicyclists. It’s safer to ride on 36th street just as it is now, and a bicycle boulevard would be better choice yet, especially for slower and more timid bicyclists. As John Schubert says in his comment on the blog post, there are better ways to make bicycling inviting.

The proposed design isn’t about improving traffic conditions, for bicyclists or anyone else. It’s about a social agenda: creating the appearance of safety for naive bicyclists to increase bicycle mode share, and making motoring more difficult. Actually, motorists would instead use the smaller parallel streets. Elimination of parking on one side of the street to create the bikeway is unlikely to be popular with residents. Snow clearance also is difficult with barrier posts and parked cars in the middle of the street.

The Montreal bikeways are the subject of a widely-publicized research study claiming a safety advantage, but the study has been demolished, see http://john-s-allen.com/reports/montreal-kary.htm
