Urbanity fails again

July 8, 2011 / / 0 Comments

Photo by my friend and UIC alum, Joshua Koonce.

I asked him about the photo’s title, “Urbanity fails again.” He replied:

I just thought it up on the fly, but you do see a lot of just these really little urban failures. Like, decayed bike lanes, weeds, potholes, gaps, sidewalk plates missing, leaky viaducts, “minor urban disasters” so to speak.

I feature Josh’s photos often on Steven Can Plan and now Grid. I also created a Flickr group for Grid where you can showcase your photos about sustainable transportation in Chicagoland.

The 3-way street

June 9, 2011 / / 0 Comments

Update June 12, 2011: Added a link to and excerpt from commentary by David Hembrow, a British blogger in the Netherlands.

How does a 3-way street work? Easy, just watch the video.

I like the term “aggressive yield” to describe the situation when a motorist does yield to pedestrians crossing the street, but in a way where they inch forward continually, slowly pushing, with a buffer or air, the people out of the way.

I really like the comment from Tuesday by Anthony Ball:

those red markers are just showing the limits of tolerable risk as established by years of system development. If the collision speeds were higher, those red circles would be far few – it’s simply a system finding its own point of stability.

If you really want to wreak havoc – try to control that system without corrective feedback (eg more rules, lights, controls, etc) and you’ll see the system kill people while it tries to find new stable relationships.

don’t forget that rules, signs, lights, etc have no direct impact on the system – they only work through the interpretation of the users.

What did David Hembrow have to say? David lives in the Netherlands and disagrees with the common sentiment that these conflicts are caused by selfish users.

I don’t see the behaviour at this junction as being about “bad habits”. What I see is simply a very badly designed junction which almost invites people to behave in the way that they do.

Dutch road junctions don’t look like and work like this – they are different for a reason: it removes the conflicts and improves safety. A long-standing theme of Dutch road design is the concept of Sustainable Safety. The concept is to remove conflict so that collisions are rare and the consequences of those which remain are relatively small. Roads are made self-explanatory so that bad behaviour is reduced and the way people behave is changed.

Reading this reminds me of the work of the students in George Aye’s class at SAIC, “Living in a Smart City.” The students attempted, through an intersection redesign, to reduce the stresses that lead to crashes.

Where are the 3-way streets in your city? Grand/Halsted/Milwaukee in Chicago comes to my mind easily. Also a lot of streets in the Loop. Oh yeah, and The Crotch, at Milwaukee/North/Damen.

Save the depot

June 3, 2011 / / 0 Comments

The last thing we did in Detroit was visit the Michigan Central Station, once the world’s tallest train station (according to contributors of Wikipedia). It’s an interesting area, with big lawns and boulevards leading up to it. There are many homeless people hanging around under the broad trees. One of them came over to ask that I don’t take her photo.

Travelers

Photo of me and the “tourist assistant” by Francesco Villa.

A guy riding his bike came over to talk to us. I asked him if he knew how to get into the train station. He did and showed us where the fence could be easily lifted (someone even tied a rope to the fence) and you could slip under. I gave him a dollar for his help (actually, he asked when I said goodbye).

Thankfully the cool station is on the National Register of Historic Places* making demolition much harder. The problem is getting the right idea and developer married to renovate the station and put it back into productive use.

Amtrak served the station until 1988. I find it odd that Amtrak, or any passenger train, came here in the first place – the station feels far from downtown Detroit. Walking is possible, along Michigan Avenue, but there’s no street activity along the way. I presume that when it was constructed in 1913, the Corktown neighborhood was a bit more hoppin’.

We walked from the train station to the Greyhound station at 1001 Howard Street, a 1.2 mile walk. We stopped for lunch at Great Wall Chinese Food. It was cheap and tasty. Another customer there told us he drives 40 minutes for this restaurant. He also said he worked the light show at the VitaminWater stage at the Movement Festival (formerly Detroit Electronic Music Festival) we spent the previous two days dancing at.

Someone has placed letters at the top of the building saying, SAVE THE DEPOT.

Detroit has so much space. What should we do with all of that room?

*The National Register website doesn’t have permalinks (stupid). So search here for reference number “75000969” or name, “Penn Central Station”. I don’t know why the NHRP calls it Penn Central Station.

A smarter marathon

May 19, 2011 / / 0 Comments

What if you could use your smartphone to identify runners in a marathon, get their stats and home country, know why they’re running and donate to their cause?

It’s another idea from the geniuses at the School of the Art Institute’s “Living in a Smart City” class with professor George Aye.

Other ideas in this project included using a new kind of tracking method that pings your spectating family and friends about your current or upcoming location so they can more easily find you. Or grouping runners into “pods” at the end so runners can meet their parties at the end of the race, saving time and eliminating the need to get to a phone.

TransportationCamp: Real-Time Pedestrian and Bike Location, Session Two

March 26, 2011 / / 0 Comments

Real-Time Pedestrian and Bike Location How can we get it? What can we do with it? How can it not be creepy?
By Eric Fischer.

My summary of the discussion

There are many existing data sources that are published or have APIs that could stand as reasonable proxies for tracking people who are walking, biking, or just ambling around the city – some of this information is given away (via Foursquare) by those who are traveling, and other information is collected in real time (buses and taxis) and after the trip (travel surveys and Flickr photos). I don’t think the group agreed on any good use for this data (knowing where people are in the city right now), nor did the group come up with ways to ensure this collection is not “creepy.”

Eric’s original question involved the location of people bicycling, but the discussion spent more time talking about pedestrians. However, some techniques in tracking and data gathering could be applied to both modes.

See final paragraph for links on “further reading” that I find relevant to this discussion.

Schedule board at TransportationCamp West on Saturday in San Francisco at Public Works SF, 161 Erie Street.

[Ideas and statements are credited where I could keep track of who said what, and if I could see your name badge.]

Eric, starting us off:
We have a lot of information about where motor vehicles (MV) are in cities.
A lot of experience of city is not about being in a MV, though.

How many bikers going through intersection that are NOT getting hurt.
Finding places where people walk and where people’ don’t.

Where do people go on foot and on bikes?
As far as I know this isn’t available

Foursquare has benefits (awards) so people are willing to give the data, but we don’t want another Please Rob Me.

In SF, there are flash mobs, sudden protests, Critical Mass

Data sources:
-buses – boarding and deboarding – you can get a flow map from this. Someone said that Seattle has this data open.
-CTPP (Census Transportation Planning Package)
-city ped count
-Eric: Where people get on/off taxis.

“CycleTracks” – sampling bias, people with iPhones
-70% of handheld devices are feature phones, not smart phones. So there’s another sampling bias.

Opt-in factor
How do you sample?

SF Planning Dept. had a little program or project ask people to plot on a map your three most common walking routes.
What is your favorite street, and where do you not like to walk?

Eric: My collection tool is Flickr. Geotags and timestamps.
flickr.com/walkingsf

Magdalena Palugh: Are there incentives for commuting by bike? There are incentives for people who vanpool.
If there is incentive, I would gladly give up my data.
Michael Schwartz (SFCTA, sp?) What is difference <> SFCTA/MTA?

-If part of this is to get at where the trouble spots are, could you have people contribute where the good/bad parts are? “This overpass really sucks.”

Tom: Can you get peds from aerial images?
-Yes, but there’re too many limitations, like shade, and tree cover. Also, aerial images may be taken at wrong time (for a while the image of Market/Castro was during festival).

Brandon Martin-Anderson: What strategies have you tried so far?
-aerial images
-Flickr/Picasa location
-Street View face blur (a lot false positives)
Anything you plot looks kind of the same.

People like to walk where other people are. For safety reasons. -Good point on real-time basis.
Eric: Not a lobbying group for peds.
Eric: Find interesting places to go.
Richard: We need exposure data.

Paris bike sharing report showed that “Cycling is faster on Wednesdays.”
Europeans more open to sharing their private details – possibly because of stricter regulation on what agencies can do with the collected data. (There was a little disagreement on this, I personally heard the opposite).

Andrew: Can we use something like Xbox Kinect to track these people?

National Bike/Ped Documentation Project – same format
Seattle – 4 different groups that do annual bike counts. UW bike planning studio.

Who pays for this?
-Transportation planners pay for this.
-Private development projects (from contractor).
-Universities, NSF, Google
-Community groups –

Notes to self

Is Census question about commuting about time or distance of “most traveled” mode?
