Weekly Reading: Be Sure to Bring a Helmet to the Bike Helmet Debate

Posted June 7th, 2013 by

Maybe it was the recent roll out of Citibike in New York. Or perhaps it was fall out from the excellent and exhaustive article in Bicycling Magazine by Bainbridge Island writer Bruce Barcott about how most of today’s helmets do very little to protect riders from concussions. (PDF of the article is available here, from Barcott’s blog) Or the Bike Helmet Safety Institute’s rebuttal. But whatever the reason, the debate about bike helmets seems to have intensified during the last week.

Everyone from fashion bloggers (warning: slightly off-color headline, but good article), to writers at The Stranger (both con and pro), to the Washington Post, to Atlantic Cities have been unpacking the data over whether helmets make people safer while riding.

Holding down the anti-helmet end of the debate is Mikael Colville-Andersen of Copenhagenize. Passionate, funny and articulate, Mikael has argued against mandated helmet laws. His great frustration is that he believes that these mandates–whether intentionally or not–are stifling cycling culture in favor of a culture of fear. He looks at the data and attempts to erode the strength of the evidence evidence used by policy makers backing mandatory helmet laws.

No one can make the case better than Mikael himself, so please check out his TED talk below.

This week Mikael’s case may have been bolstered by those who have been his most trusted debaters: the public health community. Thanks in part to the Washington Area Bicyclist Association, the federal government has withdrawn it’s long-standing claim that bike helmets are 85% effective. As WABA report:

In 1989, a study in Seattle estimated that helmets prevent 85% of head injuries. Efforts to replicate those results during the 1990s confirmed that helmets reduce injuries, but not nearly as much as the Seattle study suggested.

So the wall for anti-helmet advocates just got a bit smaller, but why should we care?

Here’s why: everyone wants cycling to be safe and convenient. These two camps diverge on how to achieve those goals. The advocates against mandatory helmet laws take the stance that empirically-proven measures like safe, separated infrastructure and a critical mass of riders make riding in the city safer. Pro-helmet advocates don’t discount those arguments or dispute the data. However, they make the case that, at least in the US, we don’t have either of those elements yet, making helmets a prudent addition to the urban cyclist’s attire.

Enter Tom Fucoloro at Seattle Bike Blog, reflecting on the new data and taking a nuanced stance regarding helmets and the launch of Puget Sound Bike Share in 2014, which will be one of the first bike share operations to have rental helmets due our mandatory helmet law. Tom writes:

There are serious concerns that King County’s all-ages helmet law could have a negative impact on use of the upcoming Puget Sound Bike Share system. Bike share is dependent on people choosing spontaneously to use the system for a short trip here or there. But it is very unlikely that many potential users will carry a helmet with them at all times. PSBS and vendor-operator Alta Bike Share have plans for a helmet vending solution, but this has not yet been successfully implemented anywhere in the world and will add cost to the system and individual users. This cost and reduced ridership due to the helmet law was factored into the system’s plan.

I do not actually care a whole lot about the helmet debate outside of the context of bike share. I choose to wear a helmet, and while I am not a supporter of helmet laws, it’s really not that hard to keep a helmet with your personal bike. There are much more important bike safety issues facing Seattle, like investing in safe bike facilities and encouraging the use of bike lights at night.

But bike share could revolutionize the way Seattle gets around. Our city is perfectly set up for it, with express transit routes moving people into urban centers where people are often dropped off within a short bike ride to their destinations.

That’s why the city/county should modify the bike helmet law for adults (not children). There is very little political will to repeal the law, but there is room for a compromise: Make it a secondary offense (or maybe even make it a secondary offense for bike share users only). Adults who are biking safely and obeying all traffic laws are not a public safety hazard, either to themselves or others. The city should support the success and safety of bike share by doing what they can to encourage the highest use of the system possible. Again: Safety in numbers is 100 percent certain to lower the collision rate for people on bikes.

The compromise here is that people who are not obeying traffic laws and are biking dangerously would get double-ticketed if they do so without a helmet on. So this law change would put an extra emphasis on lawful, safe riding while also allowing bike share to flourish. That’s a politically-palatable win-win that I think most people can agree on.

Coda

Despite 70 percent support among New Yorkers, when Citibike rolled out there were still loud howls amongst certain quarters against the program. The most prominent of these detractors was the Wall Street Journal’s editorial board, particularly the Pulitzer-prize winning Dorothy Rabinowitz, who, now infamously, observed that “The bike lobby is an all-powerful enterprise.”

Twitter responded, of course, with it’s newest handle: @BicycleLobby.

Weekly Reading: Making the Bikeable City

Posted May 24th, 2013 by

What makes a bikeable community? Is it bikeable for some, or bikeable for all? What are the structures–social, infrastructural, economic–that promote cycling?

Safety First

Thank goodness for New York. Mayor Bloomberg and Janette Sadik-Kahn have used their outsized media-shed to demonstrate to Americans around the country the profound influence cities can have in making great, liveable, bikeable communities. Through strategic interventions, data-backed policies and a fearless implementation approach, they have transformed New York’s infrastructure. In doing so, they have also provided a powerful lessons for other cities looking to create safe cycling infrastructure. Covering a newly released report regarding the impact of NYC’s new cycletracks, Portland-based Elly Blue writes:

True to form, this bike infrastructure did more than make cycling safer: The study found a 35% decrease in traffic crash related injuries to all street users on the 8th Ave path, and a whopping 58% on its 9th Ave counterpart.

What’s so exciting about this data is that it has a real impact on opinion leaders and skeptics around the country. For example, one of the Seattle Times’ editorial board writers, Jonathan Martin, recently penned an opinion piece advocating for the implementation of cycletracks in various locations throughout the city.

If You Build It…

 

Cities are recognizing the many benefits of cycling and are at various stages of transforming their public works approaches to support cycling infrastructure. But does new infrastructure result in new riders? Yes according to a new report released by the League of American Bicyclists:

From 2000 to 2011, the bicycle commuting rate has risen 80% in the largest Bicycle Friendly Communities — far above the average growth of 47% nationwide and more than double the rate of 32% in the cities not designated as bicycle-friendly.

In some Bicycle Friendly Communities, bicycle commuting rates have skyrocketed by more than 400% since 1990, including cities as diverse as Portland, Ore., and Lexington, Ky. Meanwhile, cities like Washington, D.C., Philadelphia, and Denver have more than doubled their bike commuter share since 2000.

All About the Benjamins

In Elly’s blog post from above, she also discusses the economic impacts of installing the cycletracks, and notes some astonishing findings.

…retail sales income in locally-based businesses along the 9th Ave lane went up as much as 50%. Yep, half again what they were before 2007. And this was during a recession. In the same period, borough-wide retail sales only increased 3%.

Those numbers are remarkable, but they’re not necessarily uncommon. Momentum Mag reports on a group of community activists in Memphis who looked to bikes as they searched for ways to transform their deteriorating neighborhood.

They painted temporary bike lanes and crosswalks and invited the community to “A New Face for an Old Broad,” a celebration, complete with live music, street vendors and a kids’ bike parade down the freshly striped cycle track.

“Until then, the area had been doing art walks once a year and, at best, those were bringing in 1,000 people,” Brown said. “Our goal for this day-and-a-half event, where the street itself would be a sort of theatrical performance, was maybe 5,000 people. We had 15,000 show up. The energy level was incredible. It was a huge tipping point for us – it changed the trajectory of the revitalization efforts.”

The energy didn’t wane once the event was over and bicyclists started taking advantage of the temporary lanes. Since then, the promise of permanent facilities has drawn more than $6 million in private investment. More than 15 new businesses have opened and nearly 30 properties have been renovated. Traffic has slowed, new customers are arriving on two wheels and, suddenly the rock-bottom neighborhood is one of the hottest spots in town.

Covering another economic angle, Oregon recently released a report about the economic impact of cycling on its tourism industry. Fast Company picked up the story, noting:

The Oregon study, by Dean Runyan Associates, measures the impact of bike tourism. Based on a survey of about 5,000 people, it finds that vacationing bikers spent $400 million last year, or $1.2 million a day. Of that, $175 million went on accommodation and food, $54 million on groceries, and $28 million on bike repairs, clothing, and gear. Bike tourism also secured 4,600 jobs, the report says, and $18 million in tax receipts.

A Culture of Cycle-Acceptance

As important as safety and economics are, so too is a culture of cycling. And on that front, here’s the good news: we don’t live in Saudi Arabia where the kingdom is just now set to end its ban on women cyclists.

At the same time, we should be open to the possibility that many of our institutional structures and programs may have hidden biases against certain demographics. For example, a recent report from the American Journal of Public Health:

“finds that highly influential transportation engineers relied on shoddy research to defend policies that discourage the development of protected bike lanes in the U.S. In their paper, the researchers point out that male-dominated engineering panels have repeatedly torpedoed street designs that have greater appeal to female cyclists,” according to Streetsblog.

Kids, too, are impacted by this lack of separated facility. As Susie Strachan, a mother quoted in a recent Guardian article, observes when asked whether she’d let her seven year old cycle to school, “”It’s too dangerous at this age. I don’t know anyone who does it but I think a lot of us would consider it if there were segregated bike lanes.”

Henry Grabar, writing at Atlantic Cities, argues that this separated infrastructure may also re-frame the enforcement debate. In his thought-provoking piece he argues that we should never fine cyclists for traffic infractions, asking:

Why should people riding 20-pound bicycles obey laws designed to regulate the conduct of 4,000-pound cars, to say nothing of accepting the same penalties? In terms of the damage we can cause and sustain in an accident, cyclists have more in common with pedestrians than cars and should be treated accordingly.

He continues:

It will be separated bike lanes, not the threat of fines, that reduce our incentive to jump ahead of fast-moving traffic, hop up onto sidewalks, and pedal up one-way streets. That infrastructure will also provide structural enforcement of group behavior (the first people in line decide how the rest will act) and the social pressure of group riding, which veers towards the sensible and the safe. Among the cyclists I join each morning on my way to work, there is a palpable sense of group-regulated conduct. We all make the same decisions at each light. Some of them are illegal, but all of them are safe.

The Ideal Cyclists we all strive to be

Finally, for some tongue-in-cheek fun, check out the Greater Greater Washington description of the Ideal Cyclist. It is Swiftian perfection. An excerpt:

The Ideal Cyclist stops at all traffic lights and all stop signs. He stops at all lights period, red or otherwise. You can render the Ideal Cyclist immobile with a flashlight. An octagon of any sort is paralytic.

How High Point Works in Japanese

Posted May 7th, 2013 by

We’ve rolled out yet another translation of our How High Point Works diagram, thanks this time to our illustrious civil engineer Sakaru Tsuchiya. Some green infrastructure elements, such as pervious pavements are fairly common in Japan, yet others such as bioretention systems are much less common, according to Mr. Tsuchiya. While undoubtedly the extremely dense development in many areas of the country creates a challenge for the use of green stormwater infrastructure, we hope that this translation can help explain techniques that we have used in the US and inspire new and innovative solutions abroad.

Other translations of the graphic include Spanish and Danish, as well as the original in English of course.

Weekly Reading: Cycling to Fight Climate Change and Obesity

Posted May 3rd, 2013 by

What a week it’s been. On the downside, scientists reported that the atmosphere is reaching the tipping point toward registering 400 parts per million (ppm) of carbon dioxide. For years, scientists and activists have been arguing that we need to maintain an atmospheric balance of 350 ppm if we are going to avert catastrophic climate change. Now we’re veering into an irreversible climate spiral.

Ok, that’s the bad news. Stop. Cleansing breathe.

On the upside, Wednesday saw the start of the Bike to Work Month Commute Challenge, which was kicked into high gear at the Bike to Work Breakfast yesterday. With nearly 1,000 attendees, it was a powerful convergence of bike advocates and bike-friendly community leaders. Speakers made a powerful case for cycling as an important climate mitigation strategy. Mayor McGinn noted, in introducing Governor Inslee, that, “I know you support technology to fight climate change; bikes are awesome tech to fight climate change.” Seizing the challenge, Governor Inslee went a step further, challenging the audience to put: “more carbon in our frames and less carbon in our atmosphere.”

And both men had facts to support them. For example, we know that carbon emissions from cycling are significantly less than other modes of transport, and yet cyclists make up just a fraction of commuters on the street in most American cities. And even though Washington State was ranked the most bike-friendly state in the country, we didn’t even crack the top 20 bike-friendly cities internationally, according to the good folks over at Copenhagenize. (In fact, only one city in North America did; can you guess which one?)

Of course climate benefits are just one reason why cycling is a net positive for society. A recent American Public Health Association report documented not just the GHG reductions, but also the health co-benefits from cycling in the Bay Area, concluding, in the obtuse language of academia:

[Integrated Transport and Health Impacts Model] demonstrated that active transport has the potential to substantially lower both the burden of disease and carbon emissions and can be used to complement other modeling strategies in the transportation sector. By combining a modal shift in favor of active transport with [low-carbon driving] technologies, the Bay Area and other locales will be better able to achieve carbon reduction goals.

Or, as Dr. Tom Frieden, the Director of the Centers for Disease Control put it this week: “Physical activity is closest thing to wonder drug.” Then he laments, that only 1 in 5 adults get the recommended amount of physical activity. We can, and must, do better.

So here’s the challenge: May is Bike to Work Month. The weather is beautiful. The weekend looks amazing. Hop on your bike for yourself, for your kids, for our climate. If you need help, Cascade Bicycle Club Education Foundation and other organizations offer amazing classes to get you comfortable on a bike, on the street, with a kid on the back. It’s quite the ride and maybe by the end of the weekend, you’ll decide to sign up for the Commute Challenge.

Happy riding!

 

Weekly Reading: Trees in the Urban Landscape

Posted April 26th, 2013 by

tree tags

Exploring Portland during a weekend trip, we came across these tree “price tags” along the South Park Blocks near PSU. A phenomenal public outreach campaign, they also reminded us of the multiple benefits of the urban forest that continue to be uncovered by researchers.

For example, DesignBuild Source reminds us about the importance of software like i-Tree in quantifying the value of our urban forest canopy (and perhaps more importantly, provides the nifty graphic below). It also suggests that Portland may have been low-balling their trees’ value.

ACTrees runs down the latest research about how the urban forest affects carbon storage and sequestration, which refines previous research papers. The research found:

Total tree carbon storage in U.S. urban areas (c. 2005) is estimated at 643 million tonnes ($50.5 billion value; 95% CI = 597 million and 690 million tonnes) and annual sequestration is estimated at 25.6 million tonnes ($2.0 billion value; 95% CI = 23.7 million to 27.4 million tonnes).

Download the full research paper here.

“Perhaps we should start thinking of trees as part of our public-health infrastructure,” says this fascinating article from Scientific American about how the presence of trees in your neighborhood serves as a predictor of your public health. Studying an area of Michigan where there was a large die off of trees due to the emerald ash borer, the researchers found:

“According to their mathematical model, the presence of the borer, and the subsequent loss of trees, was associated with 6.8 additional deaths per year from respiratory causes and 16.7 additional deaths per year from cardiovascular causes per 100,000 adults. That’s more than 21,000 deaths in total.”

Fast Company brings us the story of South African photographer Dillon Marsh who studies the “peculiar nature” of cell phone towers dotting the urban landscape, disguised as trees. Some examples of his work is below but be sure to also check out his website.

Growing an Urban Forest at Bell Street Park

Posted April 26th, 2013 by

With construction beginning on the first of four blocks of Bell Street Park (between 1st and 2nd Avenues), one of the most dramatic changes to date has been the removal of the existing hedge maple (Acer campestre) trees. The decision to remove the existing trees on Bell Street was given a great deal of thought, taking into consideration safety (i.e. eyes on the street), ambient light, utility conflicts, location of the trees in relation to the existing buildings and the proposed street and sidewalk alignment, as well as tree health and life expectancy. While we could have worked around some of the trees through construction, the long-term damage would have limited their overall lifespan and would have conflicted with other community desires like an enlarged pedestrian realm and a greater diversity of tree species.

That said, we know that trees in the urban setting provide many benefits including wildlife habitat, traffic calming, shade, stormwater management and pollution removal. With urban trees in the right-of-way—especially in this case since Bell Street is a major utility corridor—it is a challenge to locate trees so that they will have enough soil volume and adequate clearance from utilities to ensure their long-term success.

For Bell Street Park, the team initially looked at Silva Cells—a system that we used at Winslow Way to suspend the pavement around the tree pits to provide additional uncompacted soil volumes—for the large trees located in the smaller planting beds. In addition to providing uncompacted soil for the trees, the soil in the Silva Cells can also help to intercept and manage stormwater runoff. Due to budget constraints and concerns by Seattle Public Utilities about the placement of Silva Cells around existing utilities, the project instead specified a structural soil mix, CU-Structural Soil, to support surrounding pavements while providing increased rooting area for trees beyond the planters.

Nyssa sylvatica and Amelanchier x grandiflora ‘Autumn Brilliance’

In just a few short months, Bell Street Park will be home to a diverse mix of large and small deciduous trees–tulip poplars, tupelos, amelanchier and a variety of colorful maples–as well as a number of shore pines to provide evergreen interest and performance. We look forward to Bell Street becoming a great street park with a generous tree canopy for generations to come!
