When the marketing department plays traffic engineer

The photo shows “Cycle Lane” raised barriers, from the company Traffic Logix, on Long Island, New York, USA.

Traffic Logix Cycle Lane raised barrier

Traffic Logix Cycle Lane raised barrier

Here’s a quote from a page on the company’s Web site promoting  the barriers.

CycleLane is a smart, safe solution that provides a visual separation between vehicle and bicycle lanes. It ensures clear separation of traffic, with a unique sloped profile to prevent vehicles from entering the bike lane. The side adjacent to the vehicle lane has a high profile while the side parallel to the bike lane has a lower profile to divert bicyclists away from traffic and back into the bike lane.

Whoever wrote this evidently is not familiar with the physical concepts of center of mass or coefficient of friction. This device is a tripping hazard. A bicyclist who strays into it will not divert away from traffic, but instead will topple over into the next lane. There also is the possibility of a stopping-type incident with over-the-handlebars ejection when a bicyclist’s front wheel strikes the end of one of these barriers.

The barriers also are shown so tightly spaced that a bicyclist cannot merge into or out of the bike lane.

For these reasons, the US Manual on Uniform Traffic Control Devices, section 9C.02 says the following:

10 Posts or raised pavement markers should not be used to separate bicycle lanes from adjacent travel lanes.

Support:

11 Using raised devices creates a collision potential for bicyclists by placing fixed objects immediately adjacent to the travel path of the bicyclist. In addition, raised devices can prevent vehicles turning right from merging with the bicycle lane, which is the preferred method for making the right turn. Raised devices used to define a bicycle lane can also cause problems in cleaning and maintaining the bicycle lane.

The product is almost beyond belief; its design leaves the manufacturer wide open to liability lawsuits when bicyclists are injured or killed. The promotion could place frosting on that ugly cake, with claims of false advertising.

Still, this is only the most extreme example I’ve seen of ill-conceived, or at best, untested and unproven, marketing-driven purported safety measures targeted toward bicyclists. Some, like this one, are products, but others are design treatments which create the perception of safety without necessarily increasing actual safety.

Enough.

Electric bicycle legal hodgepdge

A task force under the auspices of the National Committee on Uniform Traffic Control Devices (NCUTCD) is currently reviewing parts of the Uniform Vehicle Code (UVC), the national model traffic law in the USA. The NCUTCD has taken on this task because the National Committee for Uniform Traffic Laws and Ordinances (NCUTLO), which maintained the Uniform Vehicle Code, unfortunately ceased operations about 10 years ago.

I am the bicyclist representative on the NCUTCD task force. Electrically-assisted bicycles are one of the hot-button issues I will have to address.

Due to the novelty of electrically-assisted bicycles, the lack of guidance in the UVC and the lack of a user constituency — bicycling advocacy organizations having largely ignored or disparaged this increasing trend — electrically-assisted bicycles are not being addressed in a consistent or logical way under the law. In some places, electrically-assisted bicycles fall under laws that apply to gasoline-powered motorized bicycles; in others, not. We are seeing a tug of war between manufacturers’ self-interest and well-intentioned but poorly-thought-out restrictions imposed by legislators concerned about safety — as with Segways, but a bigger problem than with Segways, which have never been very common.

In my opinion, vehicles defined as electrically-assisted bicycles should be permitted wherever bicycles are permitted, but should not be capable of more than 20 mph under motor power. They shouldn’t be hard-limited to that speed, because higher speed is often possible downhill — for bicycles without electrical assist too — and is advantageous to the rider, and because speed limits are reasonably imposed locally based on conditions rather than globally based on vehicle type. These opinions are consistent with the product definition and regulation promulgated by the U.S. Consumer Product Safety Commission.

The situation with state laws is more confused. I live in Massachusetts, so let’s take the Massachusetts laws as an example. They are a mess:

Definitions:

Link to Massachusetts General Laws, Chapter 90, Section1: Definitions

The definition for “motorized scooter” in Massachusetts law includes gasoline OR electrically-powered ones, stand-up or sit-down, including those also propelled by human power. An electrically-assisted bicycle, then, is identified as a “motorized scooter”. The definition for “motorized bicycle”, on the other hand, applies only to those with a gasoline motor. The definitions overlap awkwardly.

Motorized-bicycle driving rules:

Link to Massachusetts General Laws, Chapter 90, Section1b: Motorized-bicycle driving rules

These rules apply only with a gasoline motor: 25 mph max speed, 16 year minimum age, driver’s license required (obsolete — now this is the minimum age for a learner’s permit) , carte blanche to overtake on the right, somehow requiring drivers turning and crossing from the left to have X-ray vision to see through other motor vehicles, same as in Massachusetts’s rather unique bicycle laws (!!!!)  Motorized bicycles are permitted in bike lanes, but prohibited on paths: that is sensible because of the noise, pollution and typically higher speed than with bicycles. A helmet is required.

Motorized-scooter driving rules:

Link to Massachusetts General Laws, Chapter 90, Section1e: Motorized-scooter driving rules

Maximum speed 20 mph (regardless of power source –gasoline, electric, human). This law requires “keeping to the right side of the road” — which unreasonably, means not going left of center of the road or crossing a marked centerline to overtake, but can easily be misinterpreted as requiring overtaking on the right. There is no mention of use on paths or bike lanes, despite noise and pollution of gasoline-powered motorized scooters which makes them inappropriate on paths, where electrically-powered ones are more acceptable. A license or learner’s permit is required, as for motorized bicycles, but there is no mention of age; a learner’s permit can be obtained at 16 years of age. There is a totally unreasonable prohibition on use at night. A helmet is required.

The motorized scooter law was passed in a rushed, knee-jerk reaction to the fad of “mini-motorcycles” a couple of years ago.

Summary

Placing electrically-assisted bicycles in the same category with gasoline-powered mini-motorcycles and standup scooters doesn’t make much sense from the point of view of where their use would be appropriate. Prohibiting the use of electrically-assisted bicycles at night writes them off as useful transportation.

We need to do better than this. I hope and expect that the Uniform Vehicle code revision will come up with sensible laws to cover this increasingly popular vehicle type, and that Massachusetts will revise its law.

Also please see my post on this blog about electrically-assisted bicycle types and trends.

Confusion at crosswalks on multi-use paths

The crosswalk on a multi-use path has a mixed identity, unless the crossing is signalized. Motorists must yield to pedestrians in the crosswalk, but on the other hand, a stop sign facing the path normally means that cyclists yield to traffic on the road. It is certainly crucial for cyclists to slow, sometimes even stop, to check for cross traffic, and for motorists to yield to cyclists already in the crosswalk, but, again, the stop sign would normally indicate that the cyclists must yield. Confusion arises when a cyclist stops and intends to yield, then a motorist also stops — “you go first.” “No, you go first.” This causes unnecessary delay for both when the cyclist intended to cross behind the motorist, but now must wait until the motorist stops. Danger arises in addition when a motorist in a more distant lane does not stop. That motorist’s vehicle may be concealed from the cyclist by the one stopped in the closer lane — leading to the classic and ineptly-named “multiple-threat” collision. (Two crossing vehicles are involved, but the one in the nearer lane is stopped and does not pose a threat.) There would potentially be legal confusion as well in case of a collision, as both the motorist and the cyclist might claim that the other should have yielded!

Dr. Furth’s and his students’ plan for South Brookline

On March 14, 2011, I attended a meeting in Brookline, Massachusetts, a suburb of Boston. At that meeting, Dr. Peter Furth of Northeastern University, and some of his students, gave a presentation on proposals for street reconstruction and bikeways in the southern part of Brookline.

Proposed treatment for West Roxbury Parkway

Proposed replacement of two two-lane one-way roadways with shoulders by a narrowed two-way roadway without shoulders and an adjacent multi-use path; Newton Street (up the embankment at the left) to provide local access only.

Most of the streets in the project area are fine for reasonably competent adult and teen cyclists to share with motorists, though one street, Hammond Street, is much less so, with its heavy traffic, four narrow lanes and no shoulders. I do agree with a premise of the presentation, that bicycling conditions could be improved, but I suggest different treatments, such as conversion from four lanes to three, with a center turn lane which becomes a median at crosswalks, also freeing up room at the sides of the roadway for motorists to overtake bicyclists.

Please read through this introduction before looking through the photo album I have posted with images from the meeting presentation, and drawings which were taped up in the meeting room.

My Concerns with the Proposal

Generally, I am concerned with the hazards and delays — and in winter, complete lack of service — which the proposal introduces for bicyclists, and with the blockages and longer trips it introduces for motorists, resulting in delay and in increased fuel use and air pollution. Some specifics:

  • The proposed system of narrow two-lane streets and segregation of bicyclists onto parallel paths makes no provision for the foreseeable increasing diversity of vehicle types and speeds as fuel prices rise. This trend can only be managed efficiently and flexibly with streets that are wide enough to allow overtaking.
  • Proposed paths are on the opposite side of the street from most trip generators, and many movements would require bicyclists to travel in crosswalks, imposing delay, inconvenience and risk for bicycle travel on the proposed route and on others which cross it. Small children would not safely be able to use the proposed routes unless accompanied by an adult, same as at present.
  • The proposal would further degrade or eliminate bicycle access in winter, because of the proposed 22-foot roadway width, and because the proposed parallel paths could not be kept ice-free even if they are plowed.
  • Though intersections are key to maintaining traffic flow, the proposal puts forward an incomplete design for most intersections and no design for some of them.
  • The narrowed streets provide no accommodation for a vehicle which must stop while preparing to turn left into a driveway, or to make a delivery, or to pick up or discharge passengers, for bicyclists who must travel in the street to reach a destination on the side opposite the path, or for bicyclists who wish to travel faster than the path allows.
  • The proposal includes no discussion of improvements to public transportation, which would be key to reductions in congestion and fossil fuel use. There are no bus turnouts, although Clyde and Lee Streets are on an MBTA bus line, school buses use the streets in the project area, and additional bus routes are foreseeable.
  • The proposal includes a 12-foot-wide service road along Clyde and Lee Street, part of which is to carry two-way motor traffic along with bicycle and pedestrian traffic. At times of heavy use, 12 feet on the Minuteman Bikeway in Boston’s northwestern suburbs is inadequate with only pedestrian and bicycle traffic. 12 feet is not wide enough to allow one motor vehicle to pass another. Larger service vehicles (moving vans, garbage trucks etc.) could access parts of this service road only by backing in, or by driving up a curb and across landscaped areas. These vehicles would completely block other motorized traffic on the service road.
  • The proposal is expensive because it requires tearing up every one of the streets in order to narrow it, not only construction of a parallel path.

Confusion in the Presentation

There also was confusion in the presentation:

  • North is confused with south, or east with west in the captions to several photos. Due to the confusion, some photos show a path on the opposite side of the street from where the plan drawings place it.
  • Some items in the illustrations are out of proportion. In one illustration (the one near the top in this post), a two-lane arterial street is only 10 feet wide, based on the height of a Segway rider on an adjacent path, or else the Segway rider is 12 feet tall, riding a giant Segway.
  • Other details are inconsistent, for example, showing a sidewalk in a plan drawing, but no sidewalk in an image illustrating the same location.
  • There is confusion about location of some of the photos. Some cross-section drawings are shown without identification of the location in the plans. The location of one cross section is misidentified.
  • The proposal makes unsupportable claims about safety.

There also is an ethical issue: in their presentation, the students have appropriated a number of Google Street View images without attribution — a violation of copyright and of academic ethics. (Furth’s students also plagiarized photos from my own Web site for a different presentation, but I digress.)

Overview and Conclusions

The proposal generally attempts to make bicycle travel a safe option for children and for people who are new to bicycling. It fails to accomplish that, due to problems with access across streets to the proposed pathways. It also adds complication and delay for motorists and for the majority of existing and foreseeable bicycle users. It degrades and sometimes eliminates bicycling as an option in the winter months, and it pays no attention whatever to public transportation.

I have no objection to construction of a path in the parkland adjacent to the streets in the project area, but the proposal also works to enforce the use of the path by reducing the utility of the road network for bicyclists as well as for other users.

I do think that street improvements are desirable, and on one street (Hammond Street) a high priority to improve bicycling conditions, but these improvements can be achieved mostly through restriping, without the massive reconstruction, or rather, deconstruction, that has been proposed.  This narrowing the roadways is intended to increase greenspace, and also  apparently to reduce speeding, but the proposal goes way overboard in reducing capacity, convenience and flexibility. There are other options to reduce speeding, most notably enforcement and traffic-calming measures which affect speed without decreasing capacity.

The large multi-way rotary intersection of  Hammond, Lagrange and Newton Streets, West Roxbury Parkway and Hammond Pond Parkway is the one place where I consider reconstruction to be a high priority.

Education also is an essential element of any attempt to make bicycling safer and a more practical option.

Larger Contextual Issues

Long-run issues of energy cost and availability raise questions about the viability of sprawled suburbs whose residents are dependent on private motor-vehicle travel.

South Brookline is more fortunate. It is a medium-density residential area of single-family homes, only about 5 miles from the Boston city center and also only a few miles from the Route 128 corridor, a major employment concentrator. Schools, places of worship, parklands and shopping are closer than that. Bicycling can and should have a role here, but for many people and many trips, it is not an option, due to age, infirmity, distance, and the need to transport passengers and goods.

South Brookline could benefit from a comprehensive transportation plan, including strengthening of public-transportation options and maintaining arterial roads with capacity for varied existing,  foreseeable and unforeseen uses.

Developing such a plan requires skills, resources and time beyond what I can muster, and so I’ll not attempt that here.

Now, please move onto the photo album.

Manufacturing traffic jams on Grand Street, Manhattan

Someone has watched my video of Grand Street, in Manhattan, and commented:

John, I watched the Grand Street video (which was kind of fun) but I couldn’t help but notice you are passing a lot of cars, which makes your average speed seem reasonable for the environment.

That average speed, including waits for traffic lights, was 5.5 miles per hour, half my usual. Yes, I do wait for the lights, though many New York bicyclists aren’t so patient.

Please have a look at the video so you can evaluate the rest of this post. Note especially the bus stopped in the street near the start of the video, because that will play in my comments.

A ride on Grand Street, Manhattan, Take 2 from John Allen on Vimeo.

Why were my riding companion John Schubert and I passing a lot of cars — and not only parked cars? The others were stopped cars. Even at 5.5 mph, you can pass stopped cars.

Grand Street is one block north of a major arterial, Canal Street, and carries overflow traffic arriving from New Jersey via the Holland Tunnel. In case you want more detail, I’ve posted photo gallery with maps online. I thank John Ciccarelli, John Schubert and Steve Faust, my companions in exploring Grand Street, for the commentary and photos which they contributed.

Here’s one photo, as an example — and you may click on it to see it in the photo gallery. That’s Steve Faust, in the yellow parka.

Trucks blocking the Grand Street bikeway

Trucks blocking the Grand Street bikeway

Grand Street passes through Manhattan’s Chinatown — accounting for the street vendors standing and walking in the bikeway near the end of the video. Grand Street also is where the infamous Chinatown intercity buses pick up and discharge passengers, to avoid paying to use the Port Authority terminal uptown.

Grand Street now has only one travel lane. A second lane was removed to create the bikeway. Whenever a bus stops — or any other vehicle stops in the travel lane — all other traffic stops and waits behind it. Traffic backs up for several blocks.

The bus drivers park the buses diagonally to prevent motorists from sneaking past and colliding with bus passengers, though this does not prevent bicyclists from sneaking past and colliding with bus passengers. You can see one of the buses parked diagonally near the start of my video.

The traffic backups, then, illustrate the law of unintended consequences. The backups result from the redesign that created the bikeway. Possibly, the designers thought that they would calm traffic by reducing Grand Street from two travel lanes to one, in the hope that the traffic from New Jersey would go elsewhere. It didn’t work. To calm traffic, you have to reduce the actual traffic, rather than to try to cram the same traffic onto a street which can’t accommodate it. Instead of calming traffic, the designers created traffic jams, increasing fuel consumption and air pollution.

My observation about traffic flow before the redesign is confirmed by an early, prototypical pre-Streetfilms video. The video stars Mark Gorton, the money man behind Streetfilms, and shows conditions on Grand Street before the redesign. Motor traffic flowed smoothly. Gorton shows vehicles stopped to load and unload, but they don’t block the street, with a second lane available for overtaking.

Gorton’s main concern is with width of the sidewalks, a valid concern in my opinion, though the sidewalks are in fact only narrow in some blocks, and Gorton takes his advocacy to the opposite extreme. He shows a Photoshopped example of how we need to “return control of the street to the communities that live here and the people that live here” by converting part of the roadway into an open-air restaurant — placing restaurant patrons elbow-to-rear-view mirror with moving motor vehicles, where the diners can enjoy a fine mix of food aromas and exhaust stench. This treatment reflects the influence of the “shared space” designs of British architect Benjamin Hamilton-Baillie. These treatments turn the entire street into pedestrian space, and tame motorists, because they can now safely travel only at pedestrian speed without killing pedestrians.

Tellingly, Mr. Gorton never mentions bicycling. Evidently, he had not yet discovered it.

Grand Street 2005 from STREETFILMS on Vimeo.

“Return to the people” is code language for “take away space from motorized uses.” That is, to take control away from people who use motor vehicles and give it to “the people,” who all agree perfectly with the point of view expressed in the video. If that sounds vaguely Leninist to you, well, yes, I think so too. Ah, New York, where a wealthy hedge fund manager sounds off with Leninist rhetoric!

Real-world, American-style political pressures came to bear, and we now see the outcome. It’s rather clear that the community, some community — some people — residents, or business people, probably both, and for better or worse — wanted parking for motor vehicles, because there’s still nearly as much as before. On the other hand, Grand Street now has restricted loading zones — and not enough to meet demand. The business community either didn’t understand what would happen, or had too little political clout to demand more space.

Part of the street’s width was, however, “returned to the people” as a bikeway which is, in reality, a sidewalk extension, an outcome so predictable that I would have to laugh if the street hadn’t become such a traffic tangle, and if I weren’t required by law to ride on that sidewalk extension.

Bicyclists didn’t come out very well in this political exercise, and neither did motorists. Pedestrians came out best. They got their wider sidewalk, even if it is supposed to be a bikeway.

OK, now I’ve complained, so it’s my duty to offer a positive alternative.

Are you expecting a screed now on the joys of bicycling in Manhattan traffic on streets without any special treatment for bicyclists? Sorry to disappoint you, I’m not going to claim that Grand Street was a great street to ride on before the bikeway was constructed.

In my opinion, the Grand Street design is not thoroughgoing enough — not radical enough in one sense and not conservative enough in another. To make the street safe and attractive to bicyclists, including younger and less skillful ones, it would be necessary to displace through motor traffic to another street, and to get bicyclists out of the pedestrian zone. A way to accomplish that would be to traffic-calm Grand Street (or maybe another nearby parallel street) using barriers and diverters, more or less like the ones in Berkeley, California — so the street carries only light, local traffic.

In other words, transform the street into a neighborhood street, whose main purpose is local transportation at neighborhood-friendly speeds, like the bicycle boulevards in Berkeley — not a segregated mess, and not a pedestrian playground like upper Broadway in Manhattan. Many crosstown streets in Manhattan look promising for the treatment I propose, and are quite easy to ride now, even without intentional traffic calming.

If the volume of motor traffic were much lower, we might also consider widening the sidewalks where needed.

You may notice my heresy, from the point of view of segregationist bicycling advocates: some motor traffic must remain, as on the Berkeley streets, so the entire street doesn’t become a shared-space ped zone where pedestrians walk with abandon, and bicyclists have to play dodg’em.

John Schubert and I shot another video on Grand Street the same day. At the end of the video, you may view how motorists harassed us on a section without the bikeway, but while on the part with the bikeway, we waited over a minute for a Chinatown bus to unload, had to ride very slowly at one point behind a man with a food vending cart, and had to ride in the travel lane for several blocks where the bikeway was obstructed.

I volunteered at the Boston Marathon

I participated in the Boston Marathon this year, though I have never run it…

Amateur radio volunteer at the Marathon, photo by Bud Morton

When I first moved to the Boston area in 1971, I fancied that I might take up running and run the Marathon, because I liked getting physical exercise, and so I Could Say I Had Done It. Well, I tried running! — but I found that I didn’t enjoy it. I expanded my cycling horizons instead, riding increasing distances in the Boston area for transportation, then taking up bicycle touring. I briefly tried training for bicycle racing, but I came to the same conclusion as I had about running: I prefer to exercise at a brisk but moderate pace, rather than to push myself past the pain threshold in the pursuit of a trophy or Personal Goal.

Certainly,  I have enjoyed watching the Marathon. It is a wonderful and beautiful spectacle, and increasingly so over the years, as it is no longer only one race, but several races run at the same time. I tip my bicycle helmet to all the participants, with special thanks to Kathrine Switzer, whose example opened the race to women; to Bill Warner,  handcycle pioneer, who unofficially participated in the race during my early days in Boston; and to the many other competitors in the men’s, women’s, wheelchair and handcycle divisions, some racing for trophies, others only to complete the race. To the Kenyans, Ethiopians and other champion runners who build national pride and invest their prize money at home. To the marathon as a meeting place of people from around the world…

This year I became a Marathon participant, as a volunteer amateur radio operator. I wish I’d started doing this years ago. I got up early on Marathon morning, cycled over to the volunteers’ pre-event meeting, got my instructions and rode on to my post at a water stop in Wellesley, a little more than halfway through the course.  Mostly, things went quietly there. I even lay down and took a nap for a while, asking the volunteer in charge to wake me up if my services were needed. (As I said, I had gotten up early…) Later, I got to make an emergency call when a young girl spectator took ill.

I shot quite a number of video clips, and I may get around to posting them online one of these days.

The communications coordinator for the Marathon saw me arrive at the pre-event meeting on my bicycle and suggested that I might be assigned to ride the course next year. That would indeed be interesting, and I look forward to it. I’m ready — I already have an antenna for my bicycle, made by wiring up the pole of a safety flag…

Six categories of bicyclist/motorist interaction

Let me propose six different categories of cyclist and motorist interaction. This is a first try, so it’s open to modification.

1) Vehicular — to quote John Forester, who developed the concept of vehicular cycling, “bicyclists fare best when they act and are treated as drivers of vehicles.” In vehicular interactions, bicyclists and motorists alike use lane positions as described in the traffic law for vehicles, and reach those positions by merging. Purely vehicular operation  is, however,  to an extent a red herring category, because nobody, Forester included, has ever claimed that bicyclists can merge across heavy, high speed motor traffic.

2) Mostly vehicular, but with greater recognition that high-speed motoring is more compatible with bicycling if there is width for motorists to overtake without having to merge, and that bicyclists (including operators of motorized bicycles and mopeds) can’t manage to merge on roadways with high speeds and heavy traffic, making special treatments appropriate in some cases.

3) Motorists may merge across designated bike lanes. Bicyclists travel these lanes, stop for traffic lights and stop signs, but are  are (in theory) not required to merge into or across motor traffic.  In theory, because double-parked vehicles, people getting out of parked cars, slower bicyclists etc. often require bicyclists to merge out of a bike lane anyway.

4)  Neither bicyclists nor motorists merge. They only cross each other’s paths by making crossing and turning movements at designated locations. Essentially, bicyclists are treated as pedestrians. Motorists must yield to bicyclists as they do to pedestrians, and bicyclists must slow and stop as needed so motorists have time to yield. This is the typical treatment where a designated multi-use path crosses a road.

5)  Motorists must drive at pedestrian speed or come to a complete stop to avoid collisions with bicyclists they can not see, but there are special signs or markings to make motorists “aware of bicyclists”. — meaning, “aware that there might be a bicyclist.” Examples: bike lanes to the right of right turn lanes, bike boxes, blind entrances from driveways where conflict zones are indicated by colored paint, signs etc.

6) ) Motorists are required to drive at pedestrian speed or come to a complete stop to avoid collisions with bicyclists they can not see, but there are no special signs or markings to make motorists “aware of bicyclists”. Example: “shared space” plazas where direction of travel is not defined by curbs or lane lines, and traffic may travel in any direction.

These categories are in order of decreasing demands placed on bicyclists until we get to the last two, where the demands placed on motorists become excessive and so bicyclists must anticipate more motorist mistakes.

These categories also are in order of decreased efficiency of use of roadway space and of increased travel time.

As to safety, that depends on behavior, but  there is a tradeoff of safety against efficiency with all of these.

Seville: bikeway color choice by popular poll

Please excuse the Spanish in the illustration below — though really, the content is self-evident. English resumes after the illustration.

City of Seville, Spain poll for citizens to choose bikeway color

City of Seville, Spain poll for citizens to choose bikeway color

This post is a follow-up to the earlier one, “what color is your bike lane?”, which made the points, among others, that different pavement colors have specific, defined meanings, and some colors show up better than others under streetlights. These technical issues might not come to mind for José Average Citizen.

How did the city government of Seville, Spain address these issues? With the public polling form shown above.

A local cycling advocate has described the process on a Web page. A translation of the first lines reads:

The Seville authorities, who are going to spend 156 million Euros increasing danger for cyclists with a network of 77 km of segregated bikeways, most of them bidirectional — (Yes, bidirectional like these) has conducted a poll so that Sevillans can choose the color.

Very modern, participatory and democratic, yes sir!

The text continues:

Well, the first thing that is clear is that there is no way to select “none”. They’re going to screw you one way or the other, cyclist, whether you like it or not, with one or another color. So, choose, kid!

The page includes a parody catalog of colors — Brussels model: lilac, to attract women to cycling; Amsterdam model: phosphorescent green, promoting environmental consciousness; Copenhagen model: blood red, to reduce the visual impact of crashes, etc. Here’s the London model (click on it to enlarge it).

Translation: "London Model: disco laser blue. Excellent to provide good nighttime visibility. Will attract the younger set, danceaholics and night-owls to the bikeways. Use your bicycle 24 hours per day!"

Translation: London Model: disco laser blue. Excellent to provide good nighttime visibility. Will attract the younger set, danceaholics and night-owls to the bikeways. Use your bicycle 24 hours per day!

In fairness, the colors shown are not necessarily the ones used in those cities — the red for Denmark and laser-blue for England are reversed and a couple of the other colors are, well, imaginative — but, on the other hand, the quote from a safety study cited along with each proposed color is genuine.

Here’s a link to the cycling advocate’s page:

http://bicilibre.livejournal.com/2006/09/17/

What did Seville get as a result of its advanced bicycle program? Among other things, it got to be the site of the 2011 Velo-City conference, where Euro bicycle program planners meet, greet and trade ideas. More about Seville will follow — stay tuned.

Report from Seville

A Spanish advocate of integrated cycling about conditions in Seville:

Disastrous: officially (according to the Seville City Council), some 120 km of segregated cycle lanes (most of them bidirectional) have been built at an official cost of 30 million Euros. (I say “officially” and “official” because I wouldn’t trust the Seville City Council to tell me the time of the day); there is also a bit of gossiping around (plausible enough, although there is no way to verify it) saying that a sizable part of that sum has been put not into the actual building of the structures, but into the political and social marketing campaign to sell the “Seville model of bicycle promotion”; one of the most visible elements of this marketing campaign has been this year’s Velo-City conference, held recently in Seville (http://www.velo-city2011.com/), conveniently, just a few weeks before the upcoming local elections.

The mantra of the Seville City Council’s campaign is something to the effect that “the cycling mode share in Seville has risen from 0.2% to 7% as a result of our commitment to segregated structures”. The numbers used change from time to time (essentially, they say different things to different publics at different moments: a couple years ago it got as high as 8%; now the most-repeated mark is 6.6%), with another often repeated line being that “Cycling in Seville has increased ten-fold in five years (as a result of our commitment blah blah blah…)”.

If you read Spanish, you can read an analysis debunking some aspects of the Seville City Council’s bull**** in this blog post by a member of the growing community of Spanish vehicular (or integrated, as we often like to call ourselves) cyclists:

I commented on this issue in this comments thread in an English-language blog you may know, when the blog’s author repeated a bit mindlessly the official crap:

http://quickrelease.tv/?p=1476#disqus_thread

The outcome is thoroughly disastrous at several levels: not only are the segregated structures senseless and completely substandard (I am using “substandard” in the British sense here, not implying that I accept any standard at all); the city is a showcase of lost opportunities to improve real cycling conditions placed right next to the segregated crap; the local dominant cycling culture has become one of passive-aggressive cyclestrians riding on sidewalks even in trivial streets; the social status of the cyclists AND PEDESTRIANS has deteriorated (the level of conflict between pedestrians and cyclists is appalling; you can feel the increased hostility of car drivers if you ride on the roadway in a street with a cycle lane, although I have to admit, much less so than I expected); the number of cars has not decreased at all; Seville is indeed becoming an example for other clueless cities to imitate; the segregated chaos is prompting a host of Kafkaeske local ordinances to regulate the behavior of the cyclestrians… but on the other hand, the number of cyclists who don’t buy into the crap any longer is growing (http://ciudadciclista.org), and even the fact that Seville has been so extreme and reckless in following the segregationist madness is in some ways acting to our advantage: Seville has wanted to become an amazing example: some of our efforts are now directed at turning it into a horrible warning.

I also asked about crash statistics:

Regarding your question about crash stats: the situation in Seville is that of a complete information blackout. As far as I know, there is just no data publicly available. Just to give you an idea of how things are around here: over one year ago there was an article in the local press stating that “according to the conclusions of a study soon to be made public, the cycle lanes are safe for cyclists”. As you can guess, no study has been published since. Fun, uh?

The article, and the parody of it I wrote are here:

Los accidentes mortales de ciclistas crecen en carretera

The contrast with Barcelona (one of the other, if less maddened, bikelaneist black holes in Spain) is stark: In Barcelona, a report is published yearly, and the news was for two years straight that the bicycle accidents were rising significantly, although it appears that they are lately down again (haven’t paid much attention to the issue).
