Morning Links: Homeowner opposition to Westwood bike lanes may be a lie, and the CHP gets it wrong again

As I write this, the LA City Planning Commission is just hours away from a vote that could lead to the removal of Westwood Blvd and Central Ave from the city’s Mobility Plan, over the strenuous objections of virtually everyone who rides a bike on those streets.

Westwood resident Calla Wiemer has written a detailed, insightful and highly persuasive letter to the Commission arguing for keeping Westwood in the plan, which she has kindly agreed to let me share with you.

Regardless of how the commission votes, you should forward this to your councilmember before the city council takes up the matter in a few weeks.

Especially since only 42 of the roughly 3,000 homeowners in the area were concerned enough to oppose removing parking or traffic lanes to make room for bike lanes.

But those 42 are the only ones Paul Koretz seems to care about.

Dear LA CPC,

The proposed amendment to remove Westwood Blvd from the Mobility 2035 Plan and to replace it with a Gayley-Midvale route is ill-conceived. The argument in favor of such a change to the plan was articulated in a 6/22 email “Blast” from the Westwood South of Santa Monica (WSSM) Homeowners Association. The flaws in the case presented in this email Blast, however, are numerous. First, the claim that the alternative route “both maintains and respects the connectivity of the Bicycle Enhanced Network” is false. Westwood Blvd provides a through connection directly from UCLA to Westwood Station on the Expo Line and on to points south. Midvale, by contrast, truncates with a T-intersection at Santa Monica Blvd from which point riders moving in a north-south direction would need to make their way to or from Westwood Blvd to continue on course.

Second, the suggestion that a “growing presence of bicycle commuters on Westwood”, which will “slow traffic” and “create added conflicts”, can be averted by designating an inconvenient alternative route is a fantasy. A growing presence of bicycle riders on Westwood Blvd is the reality. Bike riders choose Westwood Blvd because it’s the most direct route to their destinations – destinations which are often located on Westwood Blvd for the many who shop, work, or live there. As much as non-cyclists might wish to impose an alternative route on those who ride, they simply do not have the authority to do so. The best way to avoid the conflicts the WSSM leadership is so concerned about is to provide accommodation for bike riders.

Third, the premise that “Most local residents do not feel comfortable riding through Westwood Village on Westwood Blvd” is true enough but serves better as an argument for bike lanes than against them. Westwood Blvd in its present form is a dangerous and scary place to ride a bike. Making it safer will raise the comfort level of local residents. Consider as well that most local residents similarly do not feel comfortable riding a bike on Midvale or Gayley as those streets are currently constituted. The concept in designating these alternative streets as bike routes would be to make them more inviting for bike riding. But we are better off applying such effort to Westwood Blvd which already has the cycling presence to justify it.

Fourth, continuing to speak for “most local residents” the WSSM leadership’s presumption that our ranks “have looked to our City’s planning and transportation experts to fashion” a biking alternative to Westwood Blvd is not borne out by the Association’s own survey research. The survey was conducted in June of 2014 and garnered 135 responses from the roughly 3000 homeowners in the neighborhood. Asked to express opposition to or support for “Removal of traffic or parking lanes on busy arterials for dedicated bike lanes”, only 42 respondents ticked opposition to the degree of “important” or “very important”. The number in support of removal was 18 while 59 declined to respond to such a broadly worded question and 16 others who opposed removal did not see the issue as “important” or “very important”. A more telling manifestation of local opinion on bike lanes for Westwood Blvd has been the consistently large turnout of advocates at public hearings conducted by government and civic organizations over the last few years. Of particular note, the Westwood Village Improvement Association (BID) held a series of three public hearings drawing packed houses of supporters and only a few opponents. As a result of that consultation with the community, the BID submitted a request to the city government and Councilmember Koretz that a study be conducted of bike lane designs for Westwood Blvd.

What in truth can be said about most local residents is that we are exasperated by the traffic, and yes, we look to the city’s planning and transportation experts to come up with strategies to mitigate it and to improve safety. Please let us not exclude Westwood Blvd from that process. If any street is in need of a re-envisioning, it is Westwood Blvd. Do let us keep it in the Bicycle Enhanced Network so that the planners can give us a vision of a street that works for people and businesses, not just one that is clogged with motor vehicles.

Respectfully,

Calla Wiemer

Once again, the CHP gets bike law wrong when a San Luis Obispo driver asks for advice on whether to cross the yellow line or slow down to obey the three foot passing law, forgetting that drivers are allowed to pass closer than three feet as long as they slow down and pass safely.

And despite the officer’s assertions, there is no requirement under California law that cyclists have to ride single file — especially not in a bike lane.

Nor are they required to ride to the right in a bike lane under any circumstances, ever.

Not surprisingly, the Kalamazoo driver who ran down nine bicyclists has been charged with five counts of causing death while operating a motor vehicle under the influence, as well as four counts of causing serious injury while intoxicated; blood tests showed he was under the influence of an undisclosed substance.

Weekend Links: Witnesses wanted in El Segundo death, Westwood votes for bike lanes, and more Valley CicLAvia

You’d think the life of a bike rider would be worth more than a single paragraph in the local paper.

Not to mention running it a month late — and incorrectly, at that.

The Daily Breeze has finally gotten around to mentioning that 25-year old Ricky Montoya was killed while riding in El Segundo on February 21st. And even then, only in the context that the police are looking for witnesses.

Never mind that Montoya was killed as he rode on Aviation at night, not 11 am as the paper reports.

Anyone with information is urged to call Officer Jeff Darringer at 310-524-2296 or email darringer@elsegundo.org.

Meanwhile, I’m told the El Segundo police have been conducting braking tests using what appears to be the same PT Cruiser the driver was in when he hit Montoya; you can see one of the tests below.

The same source tells me she overheard an officer tell a bystander the driver had to have been doing at least 60 mph in the 40 mph zone when he hit Montoya.

Note to the El Segundo Police Department: If you’d bothered to return my call asking for more information last month, it’s just possible we might have been able to find a witness already.

I’m just saying.

Westwood bike advocate Calla Wiemer provided a short update on Thursday’s meeting of the Westwood Business Improvement District, which considered the much-needed bike lanes on Westwood Blvd.

Here is a quick rundown on what happened at the Westwood Village BID meeting yesterday morning.

  • The board voted unanimously to request an LADOT engineering study of bike lane options for Westwood Blvd through the Village, and the message to Councilmember Koretz’s deputies was that they want it expedited and they want to make a decision quickly to endorse a plan once they get a report.
  • They ruled out requesting study of any alternatives to Westwood Blvd in order to laser focus city resources on the street that most needs improvement.
  • They took a straw poll to gauge sentiment on endorsing protected bike lanes – the more ambitious of two proposals put forth in Ryan Snyder’s “Remove Nothing Plan”, and five of ten board members indicated support even without the engineering study; the others want to see results of the study

A large number of bike lane advocates turned out, but the opposition was represented too. The results of the LADOT study will get careful scrutiny.

A rider who prefers to remain anonymous emailed to report stumbling upon a new semi-separated and, apparently, mostly useless bike lane on Los Angeles Street in DTLA.

Don’t remember hearing/reading anything about new bollards & armadillos on Los Angeles St between First & Temple, but there they were! At first, I didn’t see them, because a texter in an SUV had pulled over to the curb (in his defense, he had his emergency blinkers on). I passed on his left, and swung back into the bike lane with enough time to swerve to the right of the bollards. There are several bollards, then several intact armadillos, then a couple smashed armadillos, then more cars parked in the bike lane which forced me back out into the “car lane.” Fun ride! I stopped in the middle of the bike lane to take pictures, ’cause you’re supposed to stop right there in the bike lane, that’s what it’s for.

I’m just gonna take the lane from now on.

Bobby Close emailed to report that a member of his cycling club barely avoided a dangerous crash when some teenagers buzzed him, in clear violation of the three-foot passing law, as he rode on PCH. And that one reached out to smack the rider on the ass.

While the kids no doubt thought it was a pretty funny a prank, they actually committed an assault, which could have left them subject to prosecution.

Unfortunately, he wasn’t able to get the car’s license, which is almost impossible to do when a riders is struggling to maintain control of his or her bike.

And it probably wouldn’t matter anyway; unless there was an independent witness, police would consider it a matter of he said/she said, except in the unlikely event the kids admitted what they did.

Close’s suggestion is that cyclists should use a bike cam to record such situations; he recommends the FLY6 and FLY12 bike lights that also incorporate an HD cam, including audio.

Making the case for desperately needed bike lanes on embattled Westwood Blvd

Maybe.

Just maybe, we may finally be seeing progress in getting desperately needed bike lanes on Westwood Boulevard, after earlier plans were summarily canceled by CD5 Councilmember Paul Koretz at the urging of a local homeowner’s group.

Now local traffic planner Ryan Snyder has come up with a new plan that won’t result in the loss of a single traffic lane or parking space.

Westwood homeowner and bike advocate Calla Weimer has once again offered a detailed and insightful analysis of the plan and why it’s needed, this time in the form of a presentation to the Transportation Committee of the Westwood Village Improvement Association.

I’m posting it below with her permission.

She also notes there will be another meeting to discuss the plan at the WVIA Town Hall at 5 pm on February 23rd, at 10880 Wilshire Blvd.

Given the rampant objections to bike lanes on Westwood, there’s still a lot of opposition to the plan, even though it won’t affect anything.

Except to improve traffic flow and make a dangerous street safer for the bike riders who will arrive in droves once the Expo Line opens on the Westside.

So support from cyclists will be vital to get it approved.

Note: I initially used the term NIMBYism to describe opposition to bike lanes on Westwood Blvd. While I feel the term aptly describes many residents in the area, where even dancing is banned in Westwood Village at the insistence of local homeowners, it does not further the conversation in this instance. Terming people who object to bike lanes as NIMBYs and those who want bike lanes as activists merely results in talking past one another, and failing to engage in a genuine conversation between people with differing concerns, making consensus difficult, if not impossible. As a result, I have rewritten this piece to remove the term.

Bike Infrastructure for Westwood Boulevard

Remarks Submitted to the Westwood Village Improvement Association

4 February 2015

Calla Wiemer*

The challenge of transitioning from a car centric streetscape to one that is bike and pedestrian friendly is nowhere more pressing than on Westwood Boulevard. This heavily biked corridor exhibits an alarmingly high incidence of car-bike collision and cyclist injury. With the Westwood station of the Expo light rail line slated to open later in 2015, interest in biking the boulevard can be expected to ramp up sharply, compounding the conflict between bike and car.

This submission to the Westwood Village Business Improvement Association makes three points:

1) The incidence of car-bike collision and cyclist injury on Westwood Boulevard is unacceptably high.

2) Bike infrastructure should be developed as a network and integrated with rail transit. The Ryan Snyder “Remove Nothing Plan” jump starts the conversation on this for Westwood Boulevard.

3) Mayor Garcetti’s “Great Streets” designation for Westwood Boulevard calls on us to aspire to more than just removing nothing.

 

Collision & Injury

First, a few summary statistics on collision and injury for the whole of Westwood Boulevard will be presented. Following that, conditions will be analyzed and collision counts reported segment by segment for the length of the boulevard. Data on collision and injury are drawn from the Transportation Injury Mapping System of the University of California, Berkeley. Case identification numbers for the collisions along with explanatory notes are provided in an appendix.

  • The five year period 2009-2013 saw 36 collisions reported between bikes and motor vehicles along the 2.7 mile length of Westwood Boulevard.
  • Four of the cases were felony hit and runs.
  • The cyclist was at fault in only three cases, the motorist in 26, with no fault assigned in the 
remaining seven.
  • The cyclist was injured in all 36 cases; no motorist was injured.

Collision incidence varies along the length of Westwood Boulevard commensurate with discernible differences in conditions. The table that follows distinguishes four segments, presenting collision counts and distance in miles for each. It should be borne in mind that ridership decreases appreciably from north 
to south. Counts taken during the peak hours of 7:00-9:00 am and 4:00-6:00 pm on November 6, 2013 tallied 256 riders at LeConte Avenue, 157 at Santa Monica Boulevard, 116 at LaGrange Avenue, and 110 at Ashby Avenue (source here).

Along the most northerly segment of Westwood Boulevard through the Village, motorized traffic moves very slowly. The large number of pedestrians crossing at intersections helps to animate driver attention. Only five of the 36 collisions occurred in the half mile stretch between LeConte Avenue and Wellworth Avenue (inclusive of cross streets at both ends). This is despite the much higher ridership at the north end of the boulevard.

Bike lanes begin at Wellworth Avenue and extend to just north of Santa Monica Boulevard. These bike lanes, however, are narrow and pass through the door zone of parked cars that line both sides of the street. The lanes are often obstructed by double parked cars or cars in the process of parking or exiting parking. Motorized traffic along this stretch can move at high rates of speed. Ten of the 36 collisions occurred along this 0.6 mile stretch.

By far the most treacherous segment lies between Santa Monica Boulevard and Pico Boulevard. Motor vehicle travel lanes are too narrow to allow the three feet of passing space required for overtaking cyclists. On the northbound side, street parking is suspended during peak hours with two lanes then allocated for travel. During these hours, most cyclists cling timidly to the curb, enticing motorists to try to squeeze by within the same lane in disregard of the three-foot law. On the southbound side where parking is
permitted at all times, most cyclists cleave to the door zone, again tempting motorists to pass within the same lane. Fully half of the 36 collisions took place on this 0.8 mile stretch. This high incidence of collision occurred despite a much lower ridership than further north.

The most southerly segment from Pico Boulevard to National Boulevard carries much lighter traffic than parts north. A dedicated left turn lane is little used for the purpose since cross streets are few and lightly traveled. Thus northbound, where there is only one travel lane, motor vehicles overtaking cyclists tend to move into the center lane to afford comfortable passing space. By contrast, with two travel lanes southbound, conflict between cyclists and motorists in the rightmost lane is a problem. Still, only three of the 36 collisions occurred along this 0.8 mile stretch.

To put these numbers into perspective, consider that car-bike collisions on Westwood Boulevard occurred at a rate of 2.7 per mile per year during the period 2009-2013. For the segment between Santa Monica and Pico Boulevards, the rate was 4.5 per mile per year. By contrast, for Los Angeles County as a whole in 2011, the rate was 0.24 per mile. The rates on Westwood Boulevard are thus higher by more than an order of magnitude than for the county generally. This calls for community action to meet a reasonable standard of street safety.

 

The “Remove Nothing Plan”

The “Remove Nothing Plan” by Ryan Snyder takes as its premise that no motor vehicle travel lane or parking space should be given up. Even under this severe restriction, the plan finds scope for bike safety enhancements for each and every diverse segment of Westwood Boulevard. The plan provides a fine point of departure for discussion. By addressing Westwood Boulevard as a comprehensive whole, it stands up to a political process that has in the past treated the street in fragments affording any neighborhood association or influential local figure veto power against change. But a transportation system must function as a citywide network. It cannot be patched together at intervals counted in blocks. And with rail lines going in and interest in cycling surging in the city of Los Angeles, Westwood Boulevard cannot stand apart.

If any portion of Westwood Boulevard is dangerous for biking, the corridor itself is dangerous. Safe passage must be afforded from end to end to create a viable transportation link. For the most dangerous stretch of the boulevard between Santa Monica and Pico, the “Remove Nothing Plan” proposes sharrows (arrows painted on the pavement to indicate bikes and cars must share the lane) and signage. This would constitute a significant improvement over the status quo. When the lane is too narrow for cars to overtake bikes legally, the safest behavior for a cyclist is to take the lane. This forces motorists to move to the adjacent lane in order to pass. Cyclists who are bold enough to take the lane now on Westwood Boulevard are often met with honking and shouting. Many are too intimidated to hold their ground. Sharrows and signage would help check threatening behavior by motorists and encourage cyclists to claim a safe space.

The dangers on the Santa Monica to Pico stretch of Westwood Boulevard are of such magnitude, and the proposed mitigation measures of such ease, that the measures should be implemented without further delay. The conversation should then move on to the larger issue of how the community can best make use of its limited street space. Perhaps this discussion will be catalyzed when motorists find cyclists claiming their shared lane at a rate of one every minute or two during peak hours, especially when that means a given motorist must often overtake the same cyclist repeatedly as they leapfrog along together through stoplights. So, what other approaches might there be to not only accommodate existing cyclists, but motivate people in greater numbers to get out of their cars and take to their bikes? On this note, the discussion should turn to the mayor’s “Great Streets” initiative.

 

Westwood Boulevard as a Great Street

Mayor Garcetti has invited us to re-envision Westwood Boulevard as a “Great Street”. His designation applies specifically to the stretch that runs through Westwood Village, but the community has every opportunity to expand on that. For a street to merit the label “great”, it should act as a safe and welcoming public space. It should accommodate pedestrians and bicyclists, and not allow human life to be crowded out by motorized traffic and parked cars. It should be graced with sidewalk rest spots and beautiful landscaping and should support thriving businesses.

To achieve such a vision will involve change. Street space on Westwood Boulevard is now given over almost entirely to motor vehicles, many of which sit empty. Street parking should be on the table for discussion. Parking can be provided off street – and indeed is overwhelmingly provided off street already – whereas mobility in its various guises cannot be. Along the dangerous stretch of Westwood Boulevard between Santa Monica and Pico, more than 90 percent of parking is currently provided off street (source here). The less than 10 percent of parking that is on street unquestionably yields benefits to some individuals. But whether this is the best use of a public resource under today’s changing circumstances is a discussion the community ought to have.

People in increasing numbers do not wish to be encased in steel and glass and powered by fossil fuels for their every move about town; not when the alternative is the exhilaration of riding a bicycle. This change in lifestyle could be a great thing for public health, for the environment, and for street life. It could be a great thing for Westwood Boulevard.

Cases were selected only if Westwood Boulevard was reported as the primary street. This means collisions that occurred in an intersection with Westwood Boulevard given as the secondary street were not selected.

Data for 2013 are provisional and incomplete.

Morning Links: CD5’s Paul Koretz’ credibility questioned; CABO president calls bike lane advocates Uncle Toms

Westside councilmember Paul Koretz seems to be catching it from all sides lately.

Just days after many bicyclists — yours truly included — reacted negatively to his call for slashing greenhouse gases after killing bike lanes on Westwood Blvd, the UCLA Bicycling Academy falls just short of calling the councilmember a liar.

Consulting Economist Calla Wiemer writes that Koretz appeared before the Westwood South of Santa Monica Homeowners Association recently to explain his decision to kill the bike lanes, after promising the same group last year that the city would study them.

The Councilmember offered two justifications for the cancellation. One was that he realized that incorporating bike lanes into Westwood Boulevard would only make the situation more dangerous. The other was that he recognized an “overwhelming consensus of the community” in opposition. In light of these considerations, he determined that regardless of any LADOT findings, he would not approve bike lanes for Westwood Boulevard. There was thus no point wasting time with a study.

Yet as Wiemer explains, the bike lanes would have improved safety on one of the city’s most dangerous streets for bike riders, while moving riders out of the way of impatient motorists.

In fact, I’m told the safety portion of the study Koretz cancelled was virtually complete when he pulled the plug, and would have shown that the proposal would have no negative impact on safety — something he undoubtedly knew, despite proclaiming just the opposite as a justification for killing the project.

Which could explain his timing in killing the study last year before the results could be released.

As for his other excuse,

Koretz’s second justification for canceling the LADOT study was an ostensible “overwhelming consensus of the community” in opposition. The hundreds of riders who brave Westwood Boulevard daily on bikes would surely be surprised to discover the ease with which their interests can be overwhelmed in the view of the Councilmember. Moreover, those in favor of bike lanes extend well beyond the cycling community, or even the would-be cycling community taken to encompass those who would like to ride Westwood Boulevard but are deterred by present conditions. All who drive Westwood Boulevard regularly have the experience of getting stuck behind cyclists and wishing them out of the way. For motorists too, then, bike lanes are the answer….

With support of bike lanes for Westwood Boulevard so much in evidence, an “overwhelming consensus” in opposition would require a counterforce of a scale difficult to imagine. UCLA is, after all, the largest employer in Los Angeles after government and contributes $12.7 billion a year to the local economy. To understand the influences at work on the Councilmember, a group of UCLA students filed a public records request for all communications of the District 5 Council office pertaining to bike lanes. Covering the period February 24, 2010 to November 22, 2013, the file runs to 1035 pages. It is tough to read through all this material let alone infer any consensus from it. Views are presented on both sides of the issue with a relatively small number of people dominating the input. The most vocal opposition comes from the leadership of the Westwood South of Santa Monica Homeowners Association.

One problem with this whole scenario is that the few who run the WSSM HOA carry such disproportionate weight in the Councilmember’s assessment of public opinion. Another problem is that a group constituted on the basis of homeownership in a diverse neighborhood of single family homes and condominiums, young and old, cyclists and non-cyclists would take such a strident position on bike lanes. As a member of this homeowners association myself, I am an indication of the range of opinion that exists in the neighborhood with regard to bike lanes.

It should be deeply troubling to anyone that a single councilmember can, let alone would, derail the democratic process to satisfy an unelected homeowner’s group — not even the Neighborhood Council elected to represent all those who live, work and shop in the area, rather than just the privileged few who can afford homes in the area.

The late Dale Carnegie once wrote that there are two reasons for anything a person says or does — a reason that sounds good, and the real reason.

Koretz has given us two reasons that sound good, but don’t stand up to even the most basic scrutiny.

Which leaves us to wonder just what his real reason is.

………

Recently we discussed CABO’s opposition to AB 1193, a popular bill before the state legislature that would legalize protected bike lanes in California, which are currently prohibited under restrictive state law.

Jim Baross, president of the California Association of Bicycling Organizations, wrote in response that the group didn’t oppose the lanes, but simply wanted to maintain standards that he said would ensure their safety.

Yet the following comment from Baross, left on the Cycling in the South Bay blog in response to a story about harassment from motorists on PCH, doesn’t sound like someone who supports bike lanes, protected or otherwise.

It is so similar it’s difficult not to menton (sic) the similarity to racists’ treatment of those they consider not to belong – though nothing nearly as pervasive or violent; bicyclists are not lynched, but we are certainly being discouraged from exercising our rights – equal or less than equal. Disturbing to me is the Uncle-Tom response seeking, in effect, separate and usually inferior facilities – the back of the bus may be safer and using shoulder space may be more comfortable, bit (sic) it shouldn’t be forced on anyone by harrasment (sic) or misapplication of laws.

He’s got a valid point that no one’s choice of where to ride should be forced on them at the end of a bumper.

But to call anyone who wants safe infrastructure that doesn’t require us to share the lane with motorists an Uncle Tom couldn’t be more offensive.

Whether to bicycling advocates who disagree with his apparent opposition to anything but the same vehicular cycling approach that has stymied the growth of bicycling for the past 40 years, or to those who have suffered from real racism for the last 300.

Jim, you’ve got some serious explaining to do.

Thanks to Bike SD’sSam Ollinger for finding the comment.

Making the perfect case for Westwood bike lanes

This is how you win the fight for bikes on the streets.

For the past year, I’ve been following the fight over bike lanes on Westwood Boulevard.

Particularly since attending the single most unpleasant bike meeting in my experience earlier this year, as a group of Westside home and business owners railed against the loss of a single parking space to improve safety for those on two wheels.

Even though the upcoming Expo Line extension promises to vastly increase the number of riders on the street, as countless students, professors and other employees will take the train to the planned Westwood stop. Then bike the last couple miles from and from the station and the UCLA campus.

And even though the current proposal for a floating bike lane avoids the elimination of a single traffic lane or parking space.

I was impressed when I was forwarded a document written by Calla Wilmer last May to other members of the Westwood South of Santa Monica Homeowners’ Association laying out all the arguments in favor of accommodating bike riders on the boulevard.

And even more impressed this last week when I received a brilliantly researched follow-up document she’d written, offering the clearest, most detailed argument I’ve seen yet on why these lanes must be built.

Or any other bike project, for that matter.

With footnotes, no less.

So I asked for permission to reprint her email here, and she graciously agreed.

Wiemer has addressed every argument against the lanes, and made the case for them as strongly as I’ve ever seen. In light of this, if anyone can still oppose them, they’re going to have some serious explaining to do.

It’s not a quick read. But definitely worth your time.

And a perfect example of how to lay out an irrefutable argument in favor of bicycling infrastructure.

Cyclist Endangerment on Westwood Blvd II:

A Response to Critics and Skeptics

Calla Wiemer*

Westwood Blvd has been designated a backbone of the LA 2010 Bike Plan and targeted for the extension of now segmented bike lanes.  The leadership of the Westwood South of Santa Monica Homeowners’ Association has opposed bike lanes for the stretch of Westwood Blvd that runs through the WSSM neighborhood between Santa Monica and Pico.  The case in favor of bike lanes rests on a desire to mitigate the dangers that now confront cyclists on Westwood Blvd.  I presented analysis of the safety issues (along with a design proposal for bike lanes and a discussion of the parking situation) in a previous report submitted to the WSSM Bike Committee, hereafter referred to as “Cyclist Endangerment I”.[1]  The report generated much discussion and criticism.  This follow-up report offers a response to points raised by critics and skeptics.

Both reports are motivated by a desire to help inform stakeholders as to just how dangerous cycling is along the WSSM stretch of Westwood Blvd and to encourage the WSSM HOA leadership to reach out to HOA members with information on the situation.

This report begins with a recap of highlights from the WSSM HOA’s history related to bike lanes.  It then takes up a number of topics that have proven controversial in an effort to bring greater clarity to the discussion.  Finally, it concludes with a safety based argument in favor of bike lanes for Westwood Blvd.

WSSM HOA Bike Lane Activity

In recognition of the complexity of the bike lane issue, the WSSM HOA formed a Bike Committee which held a series of meetings.  Committee members, as appointed by the President, are:  Margaret Healey (co-chair); Craig Rich (co-chair); Marilyn Cohon; Randy Garrou; Janet Garstang; and Calla Wiemer.

A timeline of main activities is as follows:

  • 5 March 2013    WSSM Board discusses Bike Committee formation
  • 22 April 2013     first meeting of the Committee
  • 15 May 2013      Wiemer’s “Cyclist Endangerment I” submitted to the Committee
  • 9 July 2013          last meeting of the Committee (to date)

Other than my “Cyclist Endangerment I”, no written documents have been prepared by members of the WSSM Bike Committee.

The WSSM leadership has disseminated a number of e-mail communications expressing opposition to bike lanes for Westwood Blvd.  The most recent communication on this subject, dated 15 October 2013, objected even to the LA Department of Transportation undertaking study of a design proposal for bike lanes.  The only mention of safety in this communication appeared in the statement:   “The safety of pedestrians, cyclists and drivers is a critical goal.”

Discussion of Cyclist Endangerment on Westwood Blvd

My further input on five aspects of the safety discussion follows.

1)  Safety of cyclists the focus.  The WSSM e-mail of 15 October 2013 lumps together the safety of pedestrians, cyclists, and drivers.  Drivers are encased in steel and glass, and further protected by air bags that inflate on impact.  Their safety is not at serious risk at speeds characteristic of Westwood Blvd.  Cyclists and pedestrians, by contrast, are exposed bodily in spaces shared with motor vehicles.  Bike lanes have been proposed to address the problem of danger to cyclists specifically.  The three-year period 2009-2011 saw 12 reported collisions involving cyclists on the WSSM stretch of Westwood Blvd and none involving pedestrians.[2]  By absorbing cyclists into the broader grouping of “pedestrians, cyclists and drivers” the critical problem faced by cyclists is diluted.  The dangers faced by cyclists call for specific attention in connection with the debate on bike lanes. 

2)  Significance of cyclist collision data.  “Cyclist Endangerment I” reported data on the number of collisions involving cyclists by year for the WSSM stretch of Westwood Blvd.  In 2011, six collisions resulted in police reports for this six block stretch of roadway.  A WSSM Board member responded to this information as follows (8 Oct 2013, e-mail):

“I personally think the raw number isn’t very meaningful. Some may see it as low, some may see it as high. I don’t think there’s enough context to interpret the value …”

Let us develop the context.

  • One way to provide context is to compare the rate of cyclist-involved collisions per mile for the WSSM stretch of Westwood Blvd with the rate for a broader geography.  At six collisions in 0.8 miles, the per mile rate was 7.5 for WSSM Westwood.  For the county of Los Angeles in the same year, the number of collisions involving cyclists was 2219.  The number of non-freeway road miles in LA County is 20,245.[3]  That makes for a cyclist-involved collision rate countywide of 0.24 per mile.  Thus the per mile rate of cyclist-involved collisions for the WSSM stretch of Westwood Blvd in 2011 was nearly 32 times that exhibited on LA County roads in general.
  • Another way of providing context is to examine the ratio of cyclist-involved collisions relative to all collisions for Westwood Blvd versus the same ratio for the county overall.  Conceivably, Westwood Blvd is so congested and treacherous that collision rates are high for all modes of transport, with cyclists just getting caught up in that broader milieu.  As it turns out, however, for WSSM Westwood, 43 percent of all collisions in 2011 involved cyclists while for LA County as a whole the ratio was only 9.0 percent.  This means collisions involving cyclists as a share of total collisions were 4.7 times higher for the WSSM stretch of Westwood Blvd than for LA County generally.

Skeptics might still counter that the six collisions in 2011 were a statistical aberration.  Such a short stretch of roadway is subject to a high degree of variability in collision rates from year to year, after all.  But even if we take the average number of cyclist collisions over the three year period 2009-2011 to represent the statistically expected number of collisions in 2011, the count still comes to four.  On a per mile basis, that number yields cyclist collisions for the WSSM stretch of Westwood Blvd at a rate 21 times higher than for LA County as a whole and a share of cyclist collisions relative to all collisions at a rate 3.2 times higher.

Bottom line, it is hard to imagine a standard by which six collisions involving cyclists (or even four) in six blocks in one year may be seen as low.

3)  Impact of bike lanes on safety.  The above statement from the WSSM Board member continues:

“… nor is it clear what will happen to that value in the future should the lane proposal succeed or fail.”

A 2012 academic study is instructive in this regard.[4]  The authors estimate the likelihood of cyclist injury associated with different infrastructure configurations using an inventive methodology to control for cyclist and environmental characteristics.  The most dangerous configuration for cyclists is identified as “major street with parked cars and no bike infrastructure”.  Other configurations are benchmarked against this standard.  The risk measure for cyclist injury was found to be lower by nearly 50 percent for “major streets with parked cars and bike lanes”.   Although interpretation of the statistical results is complicated,[5] the authors were heartened to discover that their results conformed closely with cyclist perceptions of the relative dangers of different infrastructure configurations.

Ultimately, if bike lanes are installed on Westwood Blvd, there will be no way of knowing just how much bloodshed is avoided.  Nor can we know exactly how many people will take to riding bikes on Westwood Blvd who would otherwise have been deterred.  But as Teschke and co-authors ascertained, danger is palpable when you’re in it on a bike.  Anyone who is out riding Westwood Blvd regularly can attest to how scary it is and to the difference bike lanes would make.

Among the six cyclists involved in collisions on WSSM Westwood in 2011, five were male, only one female.  This is consistent with gender proportions tabulated by the LA County Bicycle Coalition in its biennial counts of cyclists on LA roadways.  LACBC analysis of the data has revealed, however, that when bike lanes are present the share of female riders more than doubles.[6]  The interpretation offered is that females are typically more risk averse in their cycling choices than males, and that given safer conditions they are prepared to take advantage of the opportunities.  The upshot is that installing bike lanes on Westwood Blvd would make it a more inclusive biking environment for women.

4)  Complaints about cyclist behavior.  My reporting of collision figures at the June WSSM board meeting met with outcries over the perceived recklessness of cyclists.  There may be many reasons why cyclists do not consistently adhere to rules of the road as designed for motor vehicles:  attempt to avoid conflict; laziness; haste; capability to maneuver in ways that cars cannot.  There may also be many reasons why motorists violate the right-of-way of cyclists:  distraction; haste; didn’t “see” cyclist; “couldn’t help it”.  Fault is to be found on both sides.  Solutions are nevertheless more likely to be achieved through creating safer spaces for cyclists and motorists to coexist than through changing human nature.

For the six cyclist-involved collisions reported on WSSM Westwood in 2011, case reports show the motorist at fault in four and no party assigned fault in the other two.  In all six cases, the cyclist was injured while the motorist escaped unharmed.  To state the obvious, the contest between cyclists and cars is highly unequal.

5)  Collisions involving cyclists on an upswing.  Collisions involving cyclists have trended sharply upward in Los Angeles since the mid-2000s.  Between 2007 and 2011, the number rose citywide by nearly 70 percent.  Westwood Blvd has similarly seen a dramatic increase from only two cyclist-involved collisions between 2002 and 2007 to 15 between 2008 and 2011.  For the period since 2011, we do not yet have full collision data but we do have numbers on cyclist fatalities culled from news accounts, and these show an alarming leap.  The number of cyclist fatalities in LA County for all of 2012 was 22; for the first ten months of 2013 the count had already reached 32.[7]

BikeWestwoodII-chartBy contrast the incidence of collisions of all types has been declining, as has that for collisions involving pedestrians, as the accompanying figure shows.  A major factor in the increase in cyclist-involved collisions is presumably an increase in the number of cyclists on the road.  The LACBC bike counts show ridership trending strongly upward for Los Angeles generally.  A pattern of ever more cyclists on the road incurring ever more injuries is at the heart of the case for better cycling infrastructure.

Assessment

Current conditions on Westwood Blvd are extremely dangerous for cyclists.  This is a problem for two reasons.  One is that cyclists now braving these dangers are being injured in significant numbers.  The other is that people who would like to travel the corridor by bike are afraid to do so.

Westwood Blvd would present a very different atmosphere if bike lanes were installed and people in numbers gave up their cars to cycle.  For those getting around by bike, local shopping and dining would be more convenient without the stress of having to park a car.  No time would be wasted in transit as the time spent would double as exercise.  But even those traveling by car would be better off if freed of the frustration of getting trapped behind slow moving cyclists.  Cars and bikes would have their own spaces to move at their own speeds.

The problem of cyclists impeding motorists will only get worse with the opening of the Westwood Blvd Expo Line station.  This station will not offer parking for cars.  Cyclists and pedestrians will be its mainstay.  Many who now drive to UCLA or Westwood Village will find the combination of rail and bike an attractive alternative.  We need to prepare for this.

The decision whether to install bike lanes on Westwood Blvd, or even to study proposed designs, will be made by District 5 Councilmember Paul Koretz.  In reaching a verdict, he will take into account input from neighborhood stakeholders.  As a community, we must hope that the input he receives is well informed.

[5] The reduction in the risk measure does not translate directly into an equivalent reduction in the probability of cyclist injuries, and the study does not present results in such a form.  The statistical significance of the results is sensitive to the confidence interval chosen.  Stronger significance in risk reduction is associated with a road configuration involving bike lanes and no parked cars than with bike lanes and the existence of parked cars.
