Public Character #10: Kimberly, who Plants and Waters the Traffic Circle at Charles and Albert


[Kimberly clearing leaves, planting plants in the early spring, before the blooming.]

Fun fact: I live and bike on Charles Avenue, one of the few bicycle boulevards in the Twin Cities that isn't a dud. Last spring, I happened across a woman who was weeding and planting plants on one of my favorite traffic circles  on the street. There aren't enough traffic circles on Charles because the city did a half-assed job with this street, but that makes the ones that do exist all the more precious to me. And it's great to see people in the neighborhood spending a bit of time making them look nice. 

Anyway, Kimberly was nice enough to chat with me and tell me about why she cares about this bit of public space. Here you go!

[Interview starts.]

Twin City Sidewalks [TCS]: So they install them and then they sort of let them go, the city… And then it’s up to neighbors to make them nice??


Kimberly [K]: Well when it was… so, this one specifically, it was installed probably 16 years ago, if not 17. And the reason was, at that time, I had a very young child. People could come speeding down here and go straight to Walmart. And so they wouldn’t stop here at all, and within two years there were lots of accidents. And this is ridiculous! My then husband, we petitioned the city for a stop sign. And they literally said “stop signs don’t work, but you can put in a traffic circle.” And, OK, sure. We had to go around and get all the signatures and everything. I think we needed 75% of the people…


TCS: … of every block, or just the corner? 


K: No, this block, this block. [points] Just these blocks. And then they gave us money to plant in the beginning, but I became the official garden steward.


TCS: How official?


K: Right, well, I’m not paid for it. I just volunteer. I just go head and buy the plants, and Thomas helps and Joann here always helps as well. And many neighbors. If I had put it out on our little neighbors site [they might be helping], but today was when I had time. So I’m like, I’m just gonna go out and work on it now. 


But I try to buy plants, annuals, to plant here. I just see that as my volunteer contribution for the neighborhood. But watering? We used to… we could get a permit from the city and go to the hydrant, but it just gotten to be a pain in the tush. And so Thomas and Joann will let us water with their hose, so that’s their contribution, so there’s a cost to that too.


TCS: Yeah cool. What are you just clearing leaves right now? 


K: Yeah, I’m clearing everything out. And I’m gonna actually rearrange a little bit this year and plant a few annuals and I’ll get some mulch and we attempt to water and weed throughout the season. Last year was a little rough; we didn’t get to as much. But each year is hopeful. 


TCS: Well, thanks for your labor, in this under appreciated venture.


K: Well, it’s surprising. You know, there are some people that don’t like traffic circles. And there’’s blowback about it. But for the most part people are kind, and when I’m out here people will just roll down their window when they’re driving past and say thank you. So overall I think they’re appreciated. 


TCS: I appreciate them. They slow people down. On a bike, speeding is really my issue. 


K: And that was the big thing, was the speeding and the accidents. This is supposed to be a neighborhood. Slow down people! 


TCS: Thanks!

Time For Minneapolis to Phase Out Deadly One-Way Streets


[Image from the Star Tribune.]
Last week, another young Minneapolis bicyclist, Jessica Hanson, was hit and killed by a car driver speeding late at night through the city. The story is tragic, and the second fatality this year in the city. The details of the crash, a hit-and-run driver who wasn't using lights, might make it tempting to Jess' death senseless and random.

But unfortunately, a bicycle death on 28th Street is no accident. The Star Tribune article on the killing lists a few quotes from neighbors about 28th:
Jeff Carlson, a neighbor of Hanson’s, told other neighbors gathered Friday night that he was organizing a petition to bring to the City Council and Mayor R.T. Rybak to improve sight lines and make other safety improvements at the intersection where Hanson was killed.
Carlson said drivers as well as pedestrians on Pleasant and Pillsbury Avenue S., which is one block east, often have trouble seeing cross traffic on E. 28th Street, which is one-way eastbound, because parked cars on E. 28th Street block their view. That forces them to edge forward, nearly into traffic, before crossing the street or turning into the traffic.
Magalli Aguilar Ramirez, who has lived on the corner for 13 years, said that even without watching, the accidents she has seen there have been “too many to count.”
To me, neither of these comments reaches the root of the problem. 28th Street is one of Minneapolis's obsolete one-way death traps.

These streets have long troubled me. Back in 2009, I blogged about the danger of the city's one-way street pairs, again following the bicyclist killed in Dinkytown last year, and the issue has come up many times during Streets.mn's discussion of Park and Portland Avenues.

More alarmingly, 28th Street is the exact place that was identified as Minneapolis's most dangerous spot for bikes in the city's excellent crash report released earlier this year. 28th was almost off the chart of bike accidents:


Just six months ago, I wrote this about the report:
As you can see, the city's old one-way street pairings (26th and 28th Streets in South Minneapolis) have a terrible rate of crashes per cyclist mile traveled. (I'd wager that this information could serve as a proxy for pedestrian accidents, as well.) If the city wanted to increase safety overnight, they'd begin converting these street parings (as well as 35th and 36th, University and SE 4th) into proper two-way streets right away. This is something I've suggested before. High-speed one-way streets simply should not be running through dense residential urban areas.
Jessica Hanson's death was depressingly predictable. Minneapolis' one-way residential streets encourage drivers to speed recklessly in areas filled with people, and should have been phased out long ago.


History of Minneapolis' One-Way Pairs

As anyone knows who uses them, one-way streets have advantages and disadvantages. On the plus side: they reduce the number of potential collision points by half, and they simplify signal timing to make travel more efficient. On the other side, they're confusing, and they often make trips longer as drivers circle blocks to reach their destinations. There's a debate in urban planning circles about whether these two sides cancel each other out, whether efficiency gains are outweighed by the increased trip lengths. For this reason, cities like Cedar Rapids, Iowa, are thinking of wholesale converting their one-way streets back into two-way streets. For better or worse, lots of cities have one-way streets in the downtown cores.

Minneapolis is unusual because of the large number of one-way streets that run through residential neighborhoods far from the downtown core: 26th and 28th, 35th and 36th, Park and Portland, and Blaisdell (and 1st) in South Minneapolis; 4th and University in Southeast; and Fremont and Emerson Avenue in North Minneapolis. (They're often classified as "B Minor" collectors by the Minneapolis Public Works, in the city's Orwellian classification code.)

[Detail from the Minneapolis Comprehensive Plan showing 26th and 28th.]

Some years ago, I asked the late Minneapolis Planning Commission Chair Judith Martin about this odd bit of street design. She explained to me that these streets were legacies of the freeway construction era in Minneapolis. During the 60s, before 35 and 94 were built, these streets were attempts to increase traffic flows during the construction period. Once the interstates were completed, they just stayed around. It's hard to put an egg back into its shell.



Everyday Violence v. A Few Seconds of Travel Time

The problem is that Minneapolis' residential one-ways encourage drivers to speed at 40+ miles per hour with few stops through dense neighborhoods. Most high-speed streets have wide medians, shoulders, or boulevards separating high-speed traffic from people and houses. Not so here.  Many homes along these streets are literally shoulder to shoulder with an endless stream of cars traveling at dangerous speeds. To experience this for yourself, go stand on the corner of 28th and Bloomington where cars speed through a neighborhood filled with children, or walk down SE University Avenue where cars speed next to an unprotected bike lane and frat houses filled with college students... 

The problem with high-speed roads in residential neighborhoods is that cars become exponentially more deadly when they begin to exceed 25 miles per hour, and by the time they're moving at 40 or higher, traffic accidents are almost always fatal. These streets create atmospheres of "everyday violence" along houses and neighborhoods through which they run. Parents don't let their children play in the yard, people shut their windows, shops stay vacant, fewer people walk or bike to get around.

One-way pairs force deadly traffic speeds through neighborhoods filled with people, yards, bicycles, homes, and otherwise calm residential streets. Any time you have 40 mile per hour traffic ten feet from someone's yard, it's a recipe for disaster. These streets trade a minute or two of travel time for degraded safety and quality of life city neighborhoods. Is it worth it? How many "accidents" do you have to have before saving two minutes on your trip to the freeway on-ramp isn't worth it any more?




Fixing the Problem

[1st Avenue South used to be a one-way; now it's safe.]
There are two options to fix these obsolete streets. The simplest solution is to simply turn them back into two-ways. This would immediately lower average speeds down to safer levels, and simply navigation for everyone (including bicycles). About ten years ago, former Councilmember Dean Zimmerman successfully lobbied the city to convert 1st Avenue South back into a two-way street, and today its a pleasant, safe street for everyone. 

(On the other hand, Blaisdell Avenue, its "pair", remains a one-way "collector" street. Despite the bike lane, in my opinion its a dangerous place that degrades quality of life in the neighborhood.)

Likewise, in the downtown core, both Hennepin and 1st Avenues were converted from one- to two-way streets. Most would agree that they're safer today.
[Portland Avenue S: still one-way, but calmed and far safer.]

Another solution for one-way streets is lowering speeds through traffic calming. This is basically what Hennepin County did last year on Portland and Park Avenues, removing a traffic lane and striping a wide, buffered bike lane. Further down the line, the Minneapolis Bicycle Coalition has called for adding pedestrian bump-outs and an actual concrete (planted) buffer between the cars and people. Doing all this will make these streets safe again, and last years change was a big step in the right direction.

Fixing Minneapolis' deadly legacy should be a mix of these approaches. In my opinion, larger one-way pairs, like SE University and SE 4th, should receive thorough traffic calming: bumpouts, buffered cycle tracks, medians. We need to do anything we can to reduce average speeds below the fatality threshold, while retaining the efficiencies that come with one-way directionality.

For narrower, more residential one-way streets, the city should simply get rid of them. There's no reason for 28th and 26th, 35th and 36th, or Fremont and Emerson to be dangerous one-way streets in the 21st Century. They're unsafe for families, children, pedestrians, bicyclists, and even car drivers who are bound to speed unsafely through these dense, residential neighborhoods. The city should have gotten rid of these death traps years ago. Let's let this latest tragedy be the last.


Update:

I just learned that Blaisdell is slated for a sealcoating this summer. The city could take this opportunity to re-paint the street similar to Park and Portland. Still, in my opinion, the best solution for making a street like Blaisdell safe again is to convert it back into a two-way.

Real World Urban Design Experiment #2: University LRT Traffic Calming

It’s notoriously difficult to do proper “scientific” studies of cities. You can’t run controlled experiments! Cities are too large, too complex, and filled with persnickety humans. You don’t have a “control group,” and I guarantee you that the Institutional Review Board would never approve.

That’s why urban planning relies on models, hypothetical theory, and inductive reasoning. Pretty much the only thing that planners and civic engineers can reliably study are the movement of cars, crime, and the taxable value of real estate. (Data for anything else, such as people moving on foot or happiness is almost impossibly tricky.) That’s no small reason why car volumes and real estate values become the main emphases for city policy.

But have no fear. All that can change thanks to these easy to follow Real Life Planning Experiments. There are a few places in the Twin Cities where you can experience two sets of scenarios right here, on these very streets. These are places where you have a “control group” (Test Case #A) and an “experimental group” (Urban Street Subject 5.2-C5). These are places where the conditions are similar enough that you can come to some preliminary conclusions about different urban designs, different treatments, different planning approaches.

Following these easy steps, you can conduct your own Real World Experiment. Walk, bike, and drive through the city. Find out for yourself whether urban design really makes a difference. The world is your laboratory.



Experiment #2: LRT Traffic Calming on University




Research Background:  University Avenue is the main East-West route between Saint Paul and Minneapolis, running about 10 miles between the two downtowns through the University of Minnesota-Minneapolis campus. It’s a wide street with 8’ sidewalks (on average) lined with commercial, residential, and industrial buildings of various densities and setbacks. The City, County, State, and Federal governments have spent the last few years constructing tracks for a light rail train (LRT) running down the middle of the street.

Though the train itself will not run down the tracks for another nine months, the tracks and streetscape modifications are already in place.


[University Avenue pre-existing conditions.]


[University Avenue: the before picture.]
Existing Conditions: To conduct this experiment, you have to compare University Avenue today to University Avenue before the construction. Two years ago, University had a wide right of way (ROW) devoted to car traffic. There were few street trees. Cars traveled unimpeded.


Working Hypothesis: Even without the LRT operating, the streetscape and traffic calming effects of the LRT dramatically change the experience of University Avenue, slowing down traffic and improving the experience of people on foot.


[University Avenue: the after picture.]


Methodology: Imagine that there will be no train, that the tracks are simply an elaborate design for traffic calming. Choose an interesting segment of University Avenue and go for a walk.

Think back to the street as it was before construction. How does it compare today? Is it a more or less pleasant experience? How fast do cars seem to be moving? Can you cross the street? Can you comfortably carry on a conversation with a friend or stranger?

Repeat this experiment while driving a car, or on a bicycle (with caution).
