  • This Quebecois traffic signal only turns green if it detects someone driving within the speed limit

    Screenshot from the Kalitec video of a car approaching the signal as it turns yellow. The sign is in French but explains that it will give a green if you travel below the speed limit.

    Sometimes and idea comes along that is so simple you can’t believe you haven’t seen it before. This prototype traffic signal in Quebec is red by default, and it will only turn green if its radar detects an approaching vehicle that is traveling at or below the speed limit.

    Signal creator Kalitec calls the signal EARL for “Educational Awareness Reward Light (in French it is called FRED for “feu de ralentissement éducatif”). The test signal has been installed near a school in Brossard, Canada, to enforce the 30 km/h (about 19 mph) speed limit there. It’s sort of serving the function of a speed hump, but without the hump.

    StreetsblogMASS reported on the signal with the headline “Steal This Idea”:

    The FRED light in Brossard is being tried out for a 90-day trial period on Rue Stravinski, a two-lane street that runs through a suburban residential area.

    Before the light was installed, Mayor [Doreen] Assaad said that Rue Stravinski had average vehicle speeds of 40 km/h (25 mph). But in the past week, average speeds have dropped to 29 km/h (18 mph). […]

    “Fines might be effective, but it’s effective after-the-fact,” says Mayor Assaad. “The beauty of FRED is we reward good behavior, and it’s immediate. It doesn’t record any private information, it just detects that the vehicle is coming and measures its speed. So it’s a carrot instead of a stick.”

  • City will add series of all-way stops to Pine Street on Capitol Hill

    Google Street View image of Pine at Boylston, which has crosswalk signs all around it as well as a green bike lane.
    All these crosswalk signs weren’t enough, so Pine is getting stop signs at Boylston and several other locations. From Google Street View.

    Here’s a somewhat unexpected note from SDOT:

    To enhance safety for people walking & rolling, we’re adding more 4-way stop signs on Pine St in the ❤️ of #CapitolHill. Crews worked in wind & rain today to add signs at Summit Ave & Boylston Ave. We’ll add one more at Belmont Ave as soon as weather allows. #VisionZero @jseattle

    SDOT has long resisted adding all-way stops, especially for situations where one street is clearly busier than the cross street. There are a number of reasons for this, some of which are legit and some of which are, well, questionable. It will be very interesting to see how stop signs function on Pine, a major connection between Capitol Hill and downtown that serves as a busy bike route and bus corridor while also traveling through one of the city’s most walkable neighborhood business districts.

    The most notable effect of stop signs is that compliance for yielding to crosswalk users should go way up. This is likely the primary reason for these signs on Pine. People driving are already required to stop for people crossing the street, but they don’t always do so. Any since there is nearly always someone trying to cross Pine, the stop signs here will hopefully lead to safer and more comfortable crossings. Stop signs should also have a traffic calming effect since people will not be able to build up speed over multiple blocks, something that is especially important on such a long downhill like westbound Pine.

    All-way stops can also be more efficient for all road users compared to traffic signals in many situations. U.S. cities have frankly gone way overboard with their use of signals, which are really only needed for the busiest or most complex intersections. For example, SDOT ran an experiment at NE 40th Street and The Ave in the U District back in 2014 and found that turning that traffic signal into an all-way blinking red light decreased delays for all users in all directions. So rather than upgrading the signal to accommodate the new two-way bike lane there, they have just left the red lights blinking ever since.

    All-way stops are very cheap to implement and give crosswalk users the right of way by default, which is a huge win for walkability compared to a traffic signal with a Don’t Walk phase. That all sounds great, so what’s the downside?

  • Driving kills salmon

    Screenshot from the news report showing an aerial shot of the roadway and the filter system, which includes a series of pipes leading to and from a dumpster.
    Watch the Q13 report.

    The dust from car tires is killing coho salmon, significantly reducing local populations of the vital fish species. This isn’t exactly news, but Q13 recently ran a story about one test for a roadway stormwater treatment concept using compost and sand that is worth a watch.

    The effort is specifically targeting a chemical in tires that is used to reduce wear called 6PPD. Cars leave this chemical on the roadway as dust whenever they drive, and it eventually washes into the waterways and combines with ozone to become a mostly unknown chemical called 6PPD-quinone. This chemical is fatally toxic to coho salmon (and surely other species as well). The focus on this one toxin is thanks to findings published in December 2020 by a team of UW and WSU researchers. Here’s their video from 2020:

  • Velo Bike Shop is closing after 55 years of business

    Photo from the Velo Bike Shop announcement on Facebook.

    Velo Bike Shop is closing after a remarkable and influential 55-year run. Founded in 1968, Velo helped supply the city’s bicycling boom in the 1970s. The shop continued to be an important source of bikes and service for decades on Capitol Hill before moving into the Via6 building when it opened in the Belltown/Denny Triangle area in 2013.

    Their last day of business is May 13, and they will have lots of stuff on sale until then.

    The Tamuras started renting bikes out of a closed gas station near the Arboretum in the 1960s and expanded to include a Lake Washington Boulevard location to support the city’s Bicycle Sunday events that started there in 1968. They then opened several bike shops around town initially named Velocipede. The Sekai bike brand was their shop brand, so if you have one you own a piece of Seattle bike history. Lloyd Tamura has been running the shops for decades both on Capitol Hill and then in the current location at 6th and Blanchard.

    They moved to Via6 to be part of the building’s larger bike focus, which included an indoor bike parking facility complete with showers that even non-residents could use if they joined the ViaBike Cycle Club.

    It’s sad to lose such a storied shop, and the departure will leave a void for people in the area looking for bike service. Velo has bailed me out several times in just the past year, including when I broke the chain on the cargo bike on the way home from preschool. But it’s a well-earned retirement for Lloyd.

    More details from Velo:

    After 55 years of business, Velo Bike Shop will be closing. Our final day of operation is Saturday, May 13th. We are no longer performing service and have adjusted hours:

    Tuesday: 10AM – 3PM
    Wednesday – Friday: 10AM – 6PM
    Saturday: 10AM – 5PM

    We urge you to stop by before our final date to say goodbye and pick up any items that you may need. Select gear and bikes are on sale.

    Thank you to all of the incredible customers that have supported Velo over the years. It has been a pleasure serving the Seattle cycling community.

  • ‘No Turn On Red’ is now the default for new or upgraded Seattle traffic signals

    Map of intersections getting turn on red restrictions in city center areas.
    The first intersection locations for new “No Turn On Red” signs. Work is underway, and 28 of these locations have already been completed.

    All new or upgraded traffic signals in Seattle will feature “No Turn On Red” restrictions by default while also retrofitting dozens of existing signals with the signs. So even though a turn on red ban did not make it through the Washington legislature this year, Seattle is not waiting for the state. In fact, perhaps Seattle’s experience will help create more momentum for a turn on red ban in the next session.

    The SDOT memo (PDF) announcing the department’s new policy notes a couple very troubling facts:

    Until 1959 the City of Seattle prohibited right turns on red. In 1975, the federal Energy Policy and Conservation Act (EPCA) required all states to permit right turns on red to reduce fuel consumption and estimated a travel time savings of 1–5 seconds for vehicles turning at signals. Studies following the 1975 EPCA showed that right turn on red crashes with people walking increased by 60 to 70 percent.

    There are times when the total disregard for basic ethics by the traffic engineering profession is truly astounding, and this is one of them. There is no amount of time savings for people driving cars that would ever be worth increasing right turn on red crashes with people walking by 60 to 70 percent. Yet U.S. federal policy essentially required all states to permit turns on red in the 1970s, and Washington was at the forefront of that movement. It shouldn’t require stating, but people’s lives are more important than drivers maybe saving a few seconds. Like, we all agree on that, right?

  • There are trees growing through the grate in the 4th Avenue bike lane buffer

    Tree saplings with buds on the branches growing out of a metal grate in a downtown street.

    There are a half dozen trees growing out of the metal grate in the buffer space protecting the 4th Avenue bike lane downtown across the street from Westlake Park. I noticed them while biking home Wednesday evening, and I had to stop.

    They are the same kind of tree as whatever is growing on the sidewalk next to the grate (perhaps a tree person can tell me what it is in the comments below?), and they seem to be growing from a ledge that is maybe a foot or so below street level. Who knew the downtown street grime was such fertile soil?

    But what I really love about these little doomed trees is that they are all in a perfect line inside the buffer space protecting the bike lane. It’s an adorable little metaphor about what’s possible when we reimagine our city space and remove cars from even a couple feet of it. Nobody would have expected this to happen, I’m sure. But as the renown chaos theory mathematician Ian Malcolm once said, “Life finds a way.” That is, so long as there is not a constant stream of cars mowing it down.
