Viva La Cola!

Founded in January 2009, PubliCola is a blog about Seattle written by journalists who are dedicated to non-partisan, original daily reporting that prioritizes a balanced approach to news. Started by longtime local editor and award-winning reporter Josh Feit, PubliCola is the first online-only news site in state history to get media credentials to cover the state capitol.

PubliCola was off and running. In June 2009, PubliCola hired another award-winning journalist, super-sourced Seattle city hall reporter Erica C. Barnett.

People were afraid that blogging would change journalism. Instead, we believe journalism can change blogging. Twenty-first century journalism may look and feel different, and yes Erica isn't afraid to get cranky, but we're committed to making sure online news still delivers independent, reliable, even-keeled coverage. And most of all, we're committed to making sure the coverage sparks honest civic debate.

Bringing you cola for the people, PubliCola is named after Publius Valerius PubliCola, the alias for the authors of the Federalist Papers—the original bloggers.

The first online-only news site in state history to get media credentials to cover the state capitol and Seattle city hall, PubliCola has been called a “must-read” by the Seattle Post Intelligencer and a hot “New Media Mover and Shaker” by Seattle Magazine—which also cited our own Erica C. Barnett as the city's No. 1 news nerd.

Bringing the Road Diet Debate Back to Reality

The conversation about the Nickerson “road diet” has devolved into a flawed “cars vs. bikes” debate since Mayor Mike McGinn announced the project at his Walk Bike Ride kickoff in early May.

The road diet will reduce Nickerson to two lanes with a dedicated turn lane to reduce traffic speed and accommodate safe pedestrian crossings and bike facilities.

To be clear, making Nickerson safer for bicyclists is an important component of the project. But to pretend that bikes are the sole motivation for the city’s work is to oversimplify the project and to ignore the serious pedestrian safety problems on Nickerson. The misunderstandings are in no small part due to the media coverage of the Nickerson project, which has framed it largely as a bike-safety project.  But blame also rests in opponents’ lazy, unwarranted fear of change.

A lot of that misunderstanding came to a head at Tuesday’s City Council transportation committee meeting.

Nickerson does not currently meet SDOT or federal guidelines for pedestrian crossings. Current guidelines dictate that high-speed, four-lane roads with no median cannot have uncontrolled crosswalks—which Nickerson does. Cars in the right lane will often stop for pedestrians, blocking the view of drivers in the left lane, leading to collisions with pedestrians. These safety concerns have drawn the support of pedestrian advocates and the Seattle Pedestrian Advisory Board.

SPAB Chair Tom Williams says, “We strongly support the proposal because pedestrians will certainly benefit from the engineering changes: lower speeds, shorter crossing distances, and more opportunities to cross in areas where ped traffic is generated.”

Some business interests and concerned citizens argued that the nearby, recently completed Ship Canal multi-use path eliminates the need for new bike lanes on Nickerson.

Those arguments are specious. First, the Ship Canal trail is definitely not a replacement for Nickerson. It ends at 6th Ave West, making it a path to nowhere for westbound traffic. For eastbound riders, crossing Nickerson to reach the path can be harrowing.  Unless the BNSF rail company realigns its tracks to allow completion of the trail, it won’t be a practical alternative to Nickerson.

Queen Anne resident Sharon LeVine, for example, said, “Several million dollars was recently spent to build a scenic bike road … and yet city executives want to spend 200,000 more precious dollars to reduce auto lanes on one of Seattle’s busiest arterials—$200,000 to satisfy a few bikers who won’t use the trail.”

It’s more than fair for industry interests to be worried about freight mobility. The marine industry is a strong economic presence in Seattle and they need to be able to move their goods. But leaping immediately to the rote argument that “any change will kill industry in Seattle” ignores ample evidence that road diets benefit motorized vehicles, nonmotorized vehicles, and pedestrians alike. SDOT studies of previous road diets show negligible impacts on roadway capacity. WSDOT’s preliminary traffic analysis predicts an average increase of roughly 50 cars during peak hours on Nickerson once the deep-bore tunnel opens.

Ultimately, the misguided outrage over Nickerson seems to have had little impact on the Council. Council member Tom Rasmussen says the project will move forward as planned in July. But, if Seattle continues to make its push to accommodate all modes of transportation, Nickerson will be far from the last road diet. If we’re going to make a significant environmental shift in this city, as we at least pretend we want to, we cannot afford to have progress constantly marred by unfounded protest.

    “If we’re going to make a significant environmental shift in this city, as we at least pretend we want to, we cannot afford to have progress constantly marred by unfounded protest.”

    I think this a symptom of the initiative system we have. Somehow everyone thinks they know the best way to deal with an issue and demand that they be heard. I am all for free speech and public input into projects, but at some point, the people we elect to get things done have to be allowed to just get them done. Unfortunately, everything is up for debate once it's settled. Then, once it's settled, it's up for debate again. And then this city is mired the doldrums, never living up to its potential or desires to be a world-class city.

  • I hate elliott

    Are the changes on Elliott/15th Ave a road diet? Because they suck and have created horrible traffic messes.

  • joshuadf

    It's also a safety improvement for drivers. While you're less likely to die than a pedestrian, getting hit by someone going 10+ mph over the speed limit is a serious safety problem.

  • Priscilla P

    You don't live in Magnolia. Getting from East to West requires you go either Nickerson, where the Fremont Bridge goes up an average of every fifteen minutes, or Mercer which is rightly deemed the Mercer Mess, or over the Ballard Bridge and through that labyrinth. Not to mention that Interbay and Ballard are an industrial area and this road diet will further cripple family wage businesses. To say the opponents are just lazy is such a cop out. Magnolia isn't an island but the city wants to make it so and to make it impossible for industrial business to survive in the city limits with the South Park Bridge and now this. Plus Mercer is under construction, Alaskan Way is soon to be under construction, at the very least this is the wrong plan at the wrong time. Fear of change is fear or unemployment!

  • Matt_the_Engineer

    “this road diet will further cripple family wage businesses” How so? The same amount of traffic will flow, and it'll make it easier for trucks to turn without blocking traffic.

    “Fear of change is fear or unemployment!” There's nothing wrong with fear. But fear based on false assumptions is a problem.

    “either Nickerson, where the Fremont Bridge goes up an average of every fifteen minutes” Here's some news. The diet won't make the bridge open more frequently.

  • Asdhas

    so enforce the speed limit.

    the comment that road diets are a boon to motorized vehicles is a not-too-subtle way of saying “hey all you opponents, you're stupider than shit, you're opposing something that benefits you. When will you stop being so benighted and see the light that we, the wiser environmentalists see. take our medicine, it's good for you, you are like neanderthals who believe in irrational things.”

    it's rather snobby, folks.

    Great article, Josh. I think that Road Diet advocates need to anticipate this argument and cut it off early. Road diets are not a bike/car debate. They are intended to increase flow of traffic, increase pedestrian safety and they have a side benefit of improved bike safety and they are the cheaper way of accomplishing all of this. We all win!

  • Anc

    Sometimes people are just plain wrong, and there is no way to sugarcoat it.

  • matt_the_mouseketeer

    “But leaping immediately to the rote argument that “any change will kill industry in Seattle” ignores ample evidence that road diets benefit motorized vehicles, nonmotorized vehicles, and pedestrians alike.”

    Once again, that misses the point. Making driving inconvenient in order to cut down on SOVs is a wrong-headed and misguided social engineering gone awry. This isn't about bikes or pedestrian safety (those numbers speak for themselves); this is about cars, pure and simple.

    That's fine, but making things inconvenient does so for everyone – even those driving trucks and commercial vehicles – and not just those being targeted.

    The justification document entitled Nickerson Rechannelization Facts and Answers – March 4, 2009 . includes this Q&A:

    Aren’t there are too many cars on Nickerson for this to work?

    The current average daily traffic on Nickerson is roughly 19,300 vehicles each day. National studies show that this level of traffic can be accommodated within the proposed 3-lane configuration.

    However, the actual traffic counts were as follows:

    2003 – 22,800
    2004 – blank (oddly space is there but nothing in it)
    2005 – 23,400
    2006 -19,300
    2008 – 23,700

    Now which of the above numbers doesn't fit?

    USDOT – Evaluation of Lane Reduction “Road Diet” Measures and Their Effects on Crashes and Injuries
    http://www.tfhrc.gov/safety/hsis/pubs/04082/ind…

    Surprise, surprise the break point is 20K where diets don't work so good.

    Under most average daily traffic (ADT) conditions tested, road diets have minimal effects on vehicle capacity, because left-turning vehicles are moved into a common two-way left-turn lane.(1,2) However, for road diets with ADTs above approximately 20,000 vehicles, there is a greater likelihood that traffic congestion will increase to the point of diverting traffic to alternate routes..

    I'm sure that in the follow-up study SDOT will say that volume increased from 19,300 to 21,000 (or whatever number). Now, why would SDOT pick the 2006 number that looks inaccurate even without the 2008 data?

    The link to to previous road diet studies actually links to the one Stone Way study conducted during “The Great Recession”.

  • kurisu

    What data suggests that it will inconvenience anyone? People will have an easier time with turning movements because of a center turn lane. The people who will be inconvenienced will be the ones who like to speed and swerve.

  • Matt_the_Engineer

    Good research, [morning]. I'd love to see the data behind that study, but I'm impressed that you found a credible study that helps your point.

    It's still a weak point, as I'm not sure there's a great difference between 23k and 20k, but if nothing else it does look like SDOT isn't being completely honest in their Q&A. I'm going to ask SDOT what number they actually used in their analysis and why.

  • Matt_the_Engineer

    I'd like to take back a bit of my praise, since the study you linked to doesn't seem to study traffic volumes at all (original report here), and their 20k claim is unsubstantiated and unreferenced.

  • Stoplying

    it's a complete myth that a turning lane helps people turn. people in cars are not constantly running into left turners from behind.

  • Antibitterhatred

    exactly! that's why it's so disappointing the post calls opponents lazy, wrong and chicken. Those are pretty bitter and hateful words!

  • Lanesmatter

    finally some data instead of the childish calling people lazy and chicken.

    to answer M the E's question, the reason 20 to 23K coudl be critical can be demonstrated if you take a 20 ounce glass and fill it with 23 ounces of water…..

  • Matt_the_Engineer

    “finally some data… take a 20 ounce glass and fill it with 23 ounces of water” Cute, except you're pretending to know the size of the glass. Even if that quote was backed up by data, it's an (presumably) average, and doesn't reflect an analysis of Nickerson.

    Oh, and check out the whole report. You'll find that there's great data on the side of road diets.

  • joshuadf

    I do not regard street diet opponents as stupid, but they are often misinformed. The large percentage of speeding drivers on Nickerson (and formerly Stone Way) are tiny symptoms of our national road design problem. If you make wide traffic lanes with few signals, people (including me!) will take the cue to drive fast. The US has 2-3X the death rate per mile driven as other developed countries:
    http://roomfordebate.blogs.nytimes.com/2010/05/…

    There is some sort of educational component in this. It seems obvious that a thinner road with lower speeds would be slower, right? But it's not the case, because the bottlenecks are elsewhere. It's similar to the backups on feeder arterials for I-5. You could make NE 45th St 8 lanes wide with a 45mph speed limit and the traffic would still sit there at 5pm. The two options are building a bigger freeway (at a cost of many billions), or reducing the number of vehicles (via carpooling, transit, flexible work schedules, bringing housing and jobs closer together, etc).

  • Matt_the_Engineer

    Every time a car turns in a 4-lane configuration, you have a high speed differential between vehicles. If a car comes from behind, they either have to slow down and wait, or change lanes. The problem is that the chances of an accident go up with high speed differentials and with lane changes. On top of that, the person stopped may not be turning but instead waiting for a pedestrian to cross, which puts that pedestrian in great danger when the person behind them changes lanes to keep their speed.

    And that's just on the safety side. On the traffic flow side, both the act of slowing down and waiting and the act of changing lanes slows down traffic.

    The link doesn't work. Not sure if the congestion data is found within those papers, but they clearly state that congestion becomes more of a problem at 20K – Btw, Stone Way was at 15K before slimming.

  • pro transit / pro honesty

    Let's have some reality and honesty, okay?

    You said it's unclear to you why a diff. b. 20 and 23K could make a diffrence. I explained it very well, with something called an analogy. LEt me make it more clear:

    things can fill up, so there can be something called a “ceiling” ro “threshold” in loose parlance when it comes to technical things were adding 10% more to something produces a big difference. Like, clogging up a road.

    Now, I gave only a theoretical answer. You answer by calling it cute, because you have no real answer. It's this kind of sloppy, evasive passive aggressive “discourse” on Nickerson that's hurting the credibility of the enviro types urging the road diet.

    Please just stop.

    You then complain this quote is an average so it doesn't apply to nickerson. Fail again. If a study from somewhere's else doesn't apply to nickerson because nickerson is unique, then no study applies to anything because the whole concept of using comparators or general experience is a faulty method; except it's you guys the propononets doing this by comparing to stone way.

    Again, please just stop the faulty logical and the desperate urge to simply strike out with words when you ahve no valid point to make.

    You then say there's great data for road diets. That's not the point (it also directly contradicts what you just said which is that “Avearage” can't be used to discuss nickerson). The point that has been made over and over is that a specific road diet for specifically nickerson doesn't seem supported by the ostensible reasons given, including these:

    1. bikes need it — but the bike path nearby will be finished soon and is much safer
    2. peds need it — but there's been very few injuries to peds, a traffic light solution is better or strict enforcement of speed limits
    3. teh big lie is there will be no impact on cars yet there is in fact a certain threshold on lanes filling up the other guy pointed this out by quoting the studies and expalined that they manipulated the stone way study to evade this point. And, theoretically, it makes sense. Look at it another way if one road diet doesn't hurt car traffic, why not another one? why not a road diet for I 5? You have to agree at SOME point there is a congestion impact or else you're basically intellectually….not playing fair. The most annoying part of this debate is when the enviros who loves the smell of their own farts start saying things like anyone who opposes this is lazy and stupid and calling for a return to “reality” based discussion then when someone actually goes into the data …..the proponents shut up, stay silent, and have no points to make except the non responsive responses like “oh cute” and “averages are bad” byut “go look at data in general, on average road diets are good!” Totally idiotic, thank you very much.

    The final point is there are no e w alternatives the way that stone way has dozens of n s alternatives. QA is a like a big mesa, it's hard to get around.

    The conclusion of this is that what the effete first person said is true; the folks supporting this just want to hurt car mobility to get people out of cars.

    That's your value. Why not have the balls to come out and say so? And defend it? Instead of the continual stream of lies and aspersions?

    The reference is clearly meant to be http://www.walkable.org/assets/downloads/roaddiets.pdf, which actually states:

    “The upper comfort range for
    arterial conversions appears to be between 20-25,000 ADT.
    Higher numbers have been achieved. Santa Monica officials feel
    most comfortble capping at 20,000, although they have hit 25,000.”

    Matt you wrote – “The upper comfort range for
    arterial conversions appears to be between 20-25,000 ADT.
    Higher numbers have been achieved. Santa Monica officials feel
    most comfortble capping at 20,000, although they have hit 25,000.”

    Your facts come from a paper written by the “fathers” of the road diet and even they recognize that at 20K problems with diets accelerate (see excerpt from their 1999 paper below).

    The Road Diet. “Road dieting” is a new term applied to
    “skinnying up” patients (streets) into leaner, more productive
    members of society. The ideal roadway patient is often a four-lane
    road carrying 12-18,000 auto trips per day. Other roadway patients
    may be helped through this same process. Some especially sick
    four-lane patients may be carrying 19-25,000 cars per day, but still
    qualify for diets.
    .

    Nickerson at 23K would be recognized by Burton and Lagerwey as near or over the limit and because there aren't other streets to take the load it becomes even more of problem.

    It is clear to me why SDOT used the highly questionable 19,300 volume count.

    Remember, congestion occurs at lower volume conversions. However, experts say that when the before number approaches 20,000 people move to other roads to avoid it.

    Nickerson is not a good road diet candidate for many reasons. It has too much volume. It doesn't have a high rate of collisions. It doesn't have parallel roads to take overflow. It has a high number of commercial traffic including vehicles entering and exiting.

  • morning

    Burden not Burton.

  • the side

    The woman from Feet First opened the flood gates when she boasted that this project was about “getting people out of SOVs”.

    I am all for making as many pedestrian and bicycle investments as possible, but let's build them based on their own merits and leave the social engineering behind. People will choose walking, biking, or transit as soon as it makes sense to do so, therefore we should work to make those modes as attractive as possible without creating a separate punitive condition on motorists that is worse than existing conditions.

    Advocates such as Feet First and the Cascade club, typically take things a few steps too far in the “punitive” direction. This is a shame. We need advocates in these positions to promote attractive walking and bicycling facilities in a way that does not isolate potential supporters who may also use cars, or depend on commercial vehicles.

    By immediately stating that “this is about getting people out of cars”, the main purpose for Nickerson has been lost, and the sound bite has been handed to the fearful of change groups.
