At root, we can have one or the other:
- Slow streets that are sometimes annoying, or backed up and congested, and allow multiple kinds of users. Hazards are easier to see and crashes are at slow speed and therefore minor.
- Faster, wider streets that are not congested, are more zoomy, and prioritize cars and drivers. Crashes are at higher speed, are more violent, and more catastrophic and deadly.
On Thursday, City disparages safety counter-measures |
Most speed bumps are found on local streets [rather than collectors].The oppositional structure here is telling: The idea that residents who want a safer street might be freeloading, and need to have "skin in the game." This is probably at least partly an attempt, a little clumsy, to express the idea that the City wants neighborhood consensus on traffic calming, and does not want to put something in that then is criticized for making congestion or causing slow driving that is annoying. But it's also a patronizing expression that the engineers know best and "leave it to the experts." (See Strong Towns "Conversation with an Engineer.")
But that’s not the only reason speed bump installation projects are few and far between.
There are other criteria that must be met to pursue the project, according to Kevin Hottmann, the City of Salem traffic engineer.
First, at least 600 drivers must use the road per day. If residents can count about 60 cars during rush hour, between 4 p.m. and 5 p.m., that’s a good indicator that there are at least 600 vehicles passing through on a daily basis, Hottmann said.
Also, the street would typically have a speed limit of 25 mph and one half or more of the drivers would need to be traveling at or over the speed limit.
“The issue cannot simply be one or two people speeding down the roadway every day,” said Fernandez. Most importantly, the project must be spearheaded by the community.
Neighbors may agree there is a speeding problem in the neighborhood and are often worried after accidents occur, but do not pursue the project, Fernandez said. “The community has skin in the game.”
Engineering dogma insists on evaluating for through-put on every kind of street. (Congestion Relief Task Force Oct 2018) |
Why Staff chose not to support a full 4/3 safety conversion on State Street (at the Planning Commission last year) |
Here on Fairway, the call for data suggests the City might be open to change. But then the question is, why do we have to tolerate so much speeding before we identify a "real" problem.
If a neighborhood road permits "one or two people speeding down the roadway every day," that is evidence the road is designed in a way that permits, perhaps even induces, the speeding. One or more people feel comfortable speeding. The fact of this speeding reduces comfort for people who might like to walk or bike, and the cycle of autoism takes over.
All this evidence for a design problem, not merely an instance of an isolated bad actor or careless teen.
It shouldn't take hundreds of speeders on a neighborhood street, even one designated as a "collector."
But until we grapple more thoroughly with the tension in the ways we call for slow streets near our homes and zoomy streets in urban areas through which we want to pass, we will struggle with achieving safe streets.

I believe that we need to abandon the urban street hierarchy we've created. Instead of neighbourhood, collector and arterial streets, we need to separate them into two categories: purely residential and commercial/mixed use. The street are similarly designed for safety but the latter could accommodate more lanes and more traffic. But it will not be the funnel that creates congestion, high speed accidents and no go zones for people walking and biking.
ELNA went through the speed bump process. We got a street near Weathers Park approved for two speed bumps. That was 6 years ago. Still waiting for funding. That is the other reason why they are not a good idea for making streets safer.
Yeah, it seems clear that the formal functional street classification system is not working and it needs to be modified or perhaps even scrapped with a different approach. But since we moved from a gridded system to a ramified system, it may be that the problem is not so much with the naming but is with the urban form itself.
As for speed bumps, it's not at all clear they are the right solution for traffic calming, and the City may be right to push back on speed bumps specifically. But the City should be more generous about the probability that Fairway Avenue needs calming of some kind. People shouldn't dwell too much the narrow yes/no on speed bumps here.
I should have mentioned Fisher Road NE. It doesn't have continuous bike lanes - it's an older road, I think - but it has a similar two-lane section and problems with speed.
Council discussed this in late 2017, and promised stop signs and a speed radar installation. But they did not alter the structure of the street itself. A speed study showed "The 85th-percentile speed in this posted 25 mph zone was 33.2 mph southbound and 33.9 mph northbound and so the City was prepared not to recommend calming, but to recommend a higher speed limit.
This is precisely the way that current Engineering doctrine reinforces a pernicious cycle of autoism.
I drove down Fisher Road where the City has put in stop signs and speed monitoring signs. The speed is 25 mph. The traffic is so much calmer now. The stop signs are a true benefit to not only slowing cars down, but making turns safer to get to Walmart at Devonshire. They still need to add sidewalks to make the area safe for pedestrians. I'm not sure there is room for a bike lane, but since the City is now putting Fisher Road through to Market it might soon be needed. The new connection to Market will have bike lanes, of course that will extend up to Sunnyview Road.
