Study: To Keep Bicyclists Outside the Door Zone, You Need a Buffer

A new study has found that bike lanes with a buffer next to the parking lane are better than conventional bike lanes at encouraging bicyclists to ride outside the door zone.

The study, recently published by the Transportation Research Board, concludes that wider but un-buffered bike lanes aren’t necessarily better than narrower lanes in encouraging bicyclists to ride outside the door zone. If there’s enough space to make a wider bike lane, the authors conclude, that extra space should be used to install a “narrower bicycle lane with a parking-side buffer,” which “provides distinct advantages over a wider bike lane with no buffer.”

Bicyclists are more likely to ride outside the door zone in a buffered bike lane than any other bike lane width studied.

Bicyclists are much more likely to ride outside the door zone in a buffered bike lane than in any other bike lane width studied.

Researchers reached their conclusions after observing thousands of cyclists using various bike lane configurations in Chicago and Cambridge, Massachusetts. On one Chicago street, for example, few bicyclists rode outside the door zone when the bike lane had no buffer, then after a two-foot buffer was striped, 40 percent rode outside the door zone.

That’s because the door zone is four feet wide, and riding in the center of a six-foot-wide bike lane still doesn’t give a cyclist enough clearance.

The on-street tests demonstrated that a six-foot-wide bike lane offers no advantage over one that’s five feet wide, or even four feet wide. Regardless of the width, bicyclists still ride in the center of the lane — within the radius of a typical car door swinging open. Dooring crashes are common in urban areas like Chicago: In 2012, the last year for which data is available, 18 percent of reported bike crashes were doorings.

African American Cyclists — And Others — Weigh in on Race and Biking

pfb logo 100x22

Michael Andersen blogs for The Green Lane Project, a PeopleForBikes program that helps U.S. cities build better bike lanes to create low-stress streets.

Yesterday I wrote about a complicated subject: the links between biking and race in the United States.

It’s the first in an ongoing series over the next three months that will finish with a report about ways that marginalized Americans are pushing for protected bike lanes and other quality infrastructure. In our first post, we looked at the fact that African Americans use bikes at a slightly lower rate than other Americans even though African American heads of household are twice as likely to live without a car.

We asked “Why don’t more African Americans ride bicycles?“, and as we hoped, we’ve received many thoughtful replies so far. Here are a few. I’ve boldfaced some of the writers’ key points.

Marven Norman, vice president of the Inland Empire Biking Alliance in central California:

Every single day, I continue to see hundreds of people of color(s) on bikes bumping along on sidewalks or hugging curbs of hostile arterials. Yet, absolutely nothing is done for bikes in those areas where they’re often most needed. For example, there’s not even so much as a ‘sharrow’ in a lot of LA south of I-10. The “MyFiguerora” project stops right by USC and the enhancements on MLK aren’t even worth talking about in the context of connecting the community further than again, USC. The same trend is repeated in other cities all throughout SoCal and is a pattern I’m sure any community activist in other parts of the country can relate to as well: black/brown communities lack bike accommodations.

Then there’s the issue of the metric being used. The fallacy of measuring bike demand/usage solely by ‘commute trips‘ rears its ugly head highest when we’re discussing the segment of the population that has higher unemployment than the population at large. As it is, people are more apt to jump on their bike for a ride to a shop maybe 2 miles away than to ride 10 to get to work. (Yes, I’m aware that of plenty people actually do ride farther than that, myself being one of them on occasion.) Yet, measuring only commutes, especially given the aforementioned biases, continues to result in in the conclusion that there’s no reason to build anything.

San Jose Mayor or City Council candidates Sam Liccardo, Raul Peralez, and Don Gagliardi all made appearances at last Friday’s San Jose Bike Party, pitching improvements to bicycling conditions on the city’s streets as integral to public safety. An estimated 2,500 Bike Partiers rolled out from Arena Green Park in downtown San Jose on the 18-mile, patriotically-themed “Stars & Stripes Ride” through the city’s East Side.

The June 3 primary election narrowed the field of 30 candidates down to eight candidates, competing for four seats on San Jose’s City Council: Mayor and Districts 1, 3, and, 7. Council races for Districts 5 and 9 were determined on June 3: Challenger Magdalenda Carrasco received 53 percent of the votes cast in District 5 (eastern San Jose), and incumbent Donald Rocha won 74 percent of the votes cast in District 9 (south San Jose), each above the 50 percent threshold to avoid a runoff election on November 4.

“I look forward to bringing back our public services that we’ve lost over the years — bring back our public safety,” announced Peralez, the District 3 Council candidate who finished first in the June 3 primary with 28 percent of the votes cast. Peralez touted his position as a San Jose police officer, and his work “with our youth at Juvenile Hall to try to help better them.”

Open House Tomorrow Examines Protected Bikeway Along the Embarcadero

The SFMTA and other city agencies will hold an open house tomorrow to kick off planning for a protected bikeway on the Embarcadero.

No specific proposals have been put forth yet, but a report [PDF] on the SFMTA website promises that the agency will “develop a conceptual design and cost estimate” for a “a bicycle facility that is physically separated from moving or parked vehicles and pedestrians.” Options for the project are expected to include a two-way protected bikeway on the north side of the street, and a pair of one-way protected bike lanes on either side of the street.

“What we’re hearing and observing everyday — hearing from the port, primarily — is that the status quo is no longer sustainable,” SFMTA Senior Transportation Planner Patrick Golier told SFBay.

Port Planning Director Diane Oshima praised the idea of “allocating space and increasing predictability, so that people start to adopt a culture of understanding [of] what acceptable behaviors are,” SFBay reported.

The effort comes nearly a year after a wildly popular temporary protected bikeway was tested along a short stretch of the Embarcadero, to encourage visitors to bike to the America’s Cup yacht races. Last July, the SFMTA added green paint to the existing bike lanes, making them more visible to drivers and discouraging them from blocking the lanes. Despite the paint, the street remains both one of the city’s most fearsome, and yet most popular, bicycle routes.

As SFBC community organizer Janice Li wrote in a recent blog post: “Even with the bike lane, the fast-moving traffic and lack of physical protection or separation makes it an unwelcoming ride for even the experienced. Vehicles regularly park in the bike lane, forcing bicycles into fast-moving traffic.”

People are allowed to bike on the Embarcadero’s northern sidewalk, but it’s typically crowded and can be difficult to share.

“These conditions have led to some collisions, many close calls, and detract from the comfort of all users,” the SFMTA’s report says.

Pedestrian and bike safety was the theme of the half-hour show, during which Jennings interviewed SFMTA Director Ed Reiskin; the family of Dylan Mitchell, who was killed on his bike by a truck driver in the Mission; SFPD Traffic Company Commander Mikail Ali; and Cheryl Brinkman, vice chair of the SFMTA Board of Directors. Jennings also spoke with Caltrain spokesperson Christine Dunn, who addressed the issue of deaths at railroad crossings.

The show begins with a segment featuring Walk SF Executive Director Nicole Schneider, who explains why streets like Van Ness Avenue are so dangerous. It’s a great overview of street safety in SF, especially for folks just getting introduced to the issues.

“If we don’t do something different,” Reiskin said, people will continue to die while getting around on SF’s streets. “We’re absolutely committed to doing something different, to redesigning our streets.”

Protected Bike Lanes Grow in CA as Cities Face Down Old Concerns

More and more California cities are looking to bring protected bike lanes to their streets, and a growing body of research showing the benefits they provide are giving city leaders a stronger case in the face of opposition to change.

The demand to make streets better for walking and biking is clear: local jurisdictions in California applied for more than $1 billion in funds from the state’s Active Transportation Program to build bike and pedestrian projects, triple the amount of funding available for the program.

Protected bike lanes, also known as protected bikeways or “cycletracks,” are lanes set aside for people on bikes, separated from motor traffic by physical barriers such as curbs, planters, or parked cars.

A bill currently in the California legislature, A.B, 1193, would remove some state-imposed barriers to building protected bike lanes by requiring Caltrans to establish design guidelines for them, which currently don’t exist. But even without Caltrans guidance, several cities are already building protected lanes, including Long Beach, San Francisco, San Jose, Los Angeles, and even smaller cities like Alameda and Temple City.

To earn approval from Caltrans, some of these projects have been legally categorized as “experiments,” built with easily-removable materials. This has also given planners some leeway when faced with objections from people who fear the street design changes.

A year after Long Beach installed protected bike lanes on the one-way couplet of Broadway and Third Streets, the city published a study [PDF] that found numerous benefits from the project. Crash rates decreased for all street users, bicycling and walking increased, and vehicle traffic slowed down. There was no increase in congestion, even with the removal of a traffic lane.

These findings are in line with a recent landmark study of protected bike lanes around the country, which provided new statistics showing that wherever they are implemented, they make nearly everyone on bikes and on foot feel safer and increase bicycling. In San Francisco, protected bike lanes on Market and Fell streets contributed to big jumps in bicycling; cyclist counts were up 43 percent and 50 percent on those streets, respectively, in the year after the lanes went in.

But since protected bikeways often remove a traffic lane and/or parking, cities still meet resistance from residents and merchants who fear that removing parking will hurt businesses, and that removing a traffic lane will worsen car congestion.

Sheriffs Blame Cyclist Victim in OC Road Rage Bottle-Throwing Incident

Screen capture showing Gatorade bottle thrown at cyclist. Source: Youtube

On May 31st, 2014, Bryan Larsen was bicycling on a crowded stretch of Pacific Coast Highway in south Orange County. He began to notice a pattern of harassment by the occupants of a large white 4×4 Ram Truck, with Texas license plate 65-500. When passing cyclists, the truck would spew thick black coal-rolling exhaust.

Larsen got out his phone and began to record video. He then captured this road rage incident.  The truck swerved out of the car lane toward the cyclist in the bike lane. The truck slowed and its passenger threw a bottle full of Gatorade at the cyclist. When Larsen held his phone up and shouted that he had captured the incident on video, the truck blasted more exhaust and drove away.

In a television interview, Larsen describes the incident:

I was in a lot of fear. They came into the bike lane. The tires were as big as I was and I thought they were going to run me over.

Larsen posted the video online and reported the incident, submitting the evidence to the Orange County Sheriffs Department.

OCSD responded that they were investigating, but stated that there really was nothing law enforcement could do, because, even thought it was caught on video, no sheriff had actually been present to eye-witness to the incident.

Meanwhile, the video went viral. The incident was reported in local media. Larsen approached Arizona-based advocacy organization Look! Save A Life which produced an annotated version of the video, slowing down and clarifying what occurred. Just over a month passed with no response from OCSD.

Safety in Bike-Share: Why Do Public Bikes Reduce Risk for All Cyclists?

Injuries to all cyclists declined after the launch of bike-share systems in Boston and other cities. Photo: Kelly Kline/Flickr

What if Yankees legend Yogi Berra had followed a season with 24 homers and 144 hits with one featuring 27 homers and 189 hits? Would the baseball scribes have declared “Yogi Power Shortage” because only one in seven hits was a homer instead of one in six? Duh, no. The headlines would have read, “Yogi Boosts Production Across the Board.” The fact that a greater share of base hits was singles and doubles would have been incidental to the fact that Yogi’s base hits and homers were both up.

So how is it that a study that documented drops of 14 percent in the number of cyclist head injuries and 28 percent in total cyclist injuries in U.S. cities with bike-share programs got this headline in the Washington Post last month?

wapo_hed

To be sure, those figures were buried in the study. They saw the light of day, thanks to two posts last month by Streetsblog’s Angie Schmitt. So readers know that the Post’s headline should have been: “Cities with bike-share programs see marked decrease in cyclist injuries.”

Simple enough, right? Except that to run the story straight up like that would have required the Post to set aside the unholy trinity atop Americans’ ingrained misperception of cycling safety: the beliefs that helmetless cycling is criminally dangerous; that cycling is inherently risky; and that cyclists, far more than drivers, make it so.

To see why, let’s look further into the research data that made its way into the Post story. The team of researchers, two of whom work at the Harborview Injury and Research Center in Seattle, compared five bike-share cities with five cities that did not implement bike-share programs. The bike-share cities had a total drop in reported cyclist injuries of 28 percent, versus a 2 percent increase in the control cities. The effective difference of 30 percentage points is huge.

The safety improvement in bike-share cities is all the more impressive, since those places likely saw a rise in overall cycling activity that one would expect to lead to an increase in cyclist injuries. But the expected increase in injuries is small when you take into account the safety-in-numbers phenomenon that one of us (Jacobsen) has documented for a decade and counting: You’re safer riding a bike in a community where more people ride bicycles.

Let’s train the safety-in-numbers lens on that 28 percent drop in cyclist injuries in bike-share cities and consider why the injury risk fell instead of increasing:

Watch: D10 Supervisor Candidates Weigh in on Muni, Parking, and Bike Lanes

The candidates running for District 10 supervisor this November gave some telling responses to transportation questions last week. The first debate of the D10 race was held at the Potrero Hill Democratic Club and moderated by SF Chronicle reporter Marisa Lagos, who asked some pointed questions on issues around Muni, parking, and bike lanes in SF’s eastern and southeast neighborhoods.

The five candidates, as seen seated from left to right in the video above, included Ed Donaldson, Marlene Tran, incumbent Malia Cohen, Tony Kelly (the close runner-up in the most recent election), and Shawn Richard. The video was provided by Kelly’s campaign.

Here’s a summary of highlights from the transportation section:

  • 38:00: Lagos tested candidates on some transit fundamentals by asking them each to write down all of the Muni lines that serve Potrero Hill, then show their answers to the crowd. The responses, which acted as a score card of sorts, weren’t exactly uniform.
  • 40:30: Lagos also drew some differing responses with her follow-up question: ”What would you do to improve Muni service to the hill?” Notably, Donaldson was the only one to mention bringing back Sunday parking metering for Muni funding, and was met with hisses from the audience.
  • 43:00: Lagos asked, “Should private buses be allowed to stop at public bus stops?” The consensus from candidates is a resounding “no.”
  • 44:35: Candidates were asked whether they “agree with the current ratio of residential units to parking spaces in new developments.” All candidates except Kelly said they felt current parking maximums were too low. (On parking, it’s worth noting that Kelly pushed the idea of allowing nearby residents to park at new meters for free.)

What a Great Pilot Bike Lane Project Looks Like: 3 Best Practices

Cheap and flexible: A pilot protected lane project on Multnomah Street in Portland. Photo: Green Lane Project

pfb logo 100x22

Michael Andersen blogs for The Green Lane Project, a PeopleForBikes program that helps U.S. cities build better bike lanes to create low-stress streets.

From Calgary to Seattle to Memphis, the one-year pilot project is becoming the protected bike lane trend of 2014.

Street designers looking to use the design have been putting down their digital renderings and picking up plastic posts and barrels of paint, city staffers from around the country said in interviews this week.

“I think there’s been sort of this realization that we don’t have to be so theoretical in our work and we don’t have to be so tied to the process,” said Kyle Wagenschutz, pedestrian and bicycle coordinator for the City of Memphis. “By doing a pilot project you’re able to very quickly put a substantial change on the ground in your city.” The point isn’t to avoid public dialogue, Wagenschutz argues. Just the opposite.

Because a pilot project lets ordinary people see a new street design in action, rather than “spending three to five years talking about renderings and sketch models,” Wagenschutz said, “you’re changing the starting point for your input. You’re changing the point by which people begin to communicate. … The dialogue is based on this new experience that they’re having rather than a dialogue about what might be.”

It’s not unlike the philosophy of many software startups, Wagenschutz said: “Ready, fire, aim.”

But that doesn’t prevent some pilot protected bike lane projects from misfiring. So we talked to a few creators of successful ones to get their advice.
