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.

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?

What is difference <> SFCTA/SFMTA?

Design a promotional message

February 10, 2011 / / 0 Comments

If you were asked to design a poster, postcard, flyer, or what have you, to promote bicycling, what would you create?

A photo of my sister riding a bicycle in Chicago alongside the text, “I want to get in shape, waste less time, and save money.” Similar to Mikael’s “The bike, think about it.”

No one asked me to design the poster above. Mikael Colville-Anderson of Copenhagenize and Copenhagen Cycle Chic (who I met in January 2011) is constantly reimagining car advertisements and plastering cheeky messages on photos. I created this to expand my creativity, use computer software I rarely try out, as well as promote one of the answers to a lot of problems, be they personal, environmental, or social.

I don’t think there’re enough positive messages about bicycling being spread in media or in our media-filled physical environment – we see the opposite. If you watched the Super Bowl commercials on Sunday (or online today), you’d have seen Audi’s “Green Police” arresting people for not recycling or for driving something other than their “clean diesel” car. Audi advertised the same “clean diesel” car in a different commercial that suggested bicycling was difficult and degrading, and probably only done while it’s raining.

To promote bicycling as the cure to what ails us, Mikael designed this poster of a patch kit and the text, “The bicycle. Fixing broken cities. You’re welcome.”

Mikael and I posing for a shot next to hand and foot rail for cyclists after riding our bikes around Copenhagen after sipping some beer and eating expensive, but tasty, hamburgers.

Promoting bicycling doesn’t always need a narrative message, though. This poster for the great people of San Francisco identifies each neighborhood by a kind of bicycle. The funniest one is the exercise (stationary) bike for Castro. Think about the neighborhoods in your city – which one would a fixie represent and which one would get the cargo bike?

One of my favorite messages is apparently quite old: Put some fun between your legs.

Italian train network looks modern and decrepit simultaneously

February 1, 2011 / / 0 Comments

Italian trains and stations look modern and decrepit simultaneously. One of a thousand observations on my trip to Europe in December and January.

MODERN: Roma Termini (main station) has at least 50 automatic ticket vending machines that accept credit and debit cards and display text in multiple languages.

DECREPIT: Many train cars have copious graffiti. This train appeared as if it hadn’t moved in weeks, like the one on the right in this photo.

MODERN: But then Italy has something the United States will not have for several more years (go Florida!): a high-speed train. This one travels up to 300 KM/H (186 M/H). I caught my train going 247 KM/H from Roma to Milano.

In Chicago, I think there’s more of a balance to the train state of affairs: not so modern, but not so decrepit either. New stations opened on the Brown Line but without the fancy glass ceilings from the early renderings (had to cut costs). Train cars are 40 years old (new ones in testing). Subway stations have dismal lighting (coupled with the dirty windows it’s hard to tell the difference between the platform and the tunnel areas). Metra just started accepting credit cards at the downtown stations in 2010.

Thanking your city’s bicycle riders

January 13, 2011 / / 0 Comments

A bike counter outside of City Hall in central Copenhagen on the westbound side of Hans Christian Andersen Boulevard.

A nice way of saying, “Hey, the city values you for riding your bike.”

It’s currently 1°C at 9:21 in the morning of Monday, January 10, 2011. So far today, 2,142 people have biked past this counter (and only in this direction, westbound). 43,504 have biked past in 2011 (again, westbound only) and it’s only the 10th day of the year.

What’s the best your city can do? I’m a little embarrassed to say Chicago can only throw 3,100 cyclists in the ring, in warm weather, and in two directions on Milwaukee Avenue at Grand Avenue.

UPDATE: One thing this sign might say if it had some intelligence and a voicebox, “Hey cyclist, you’re one of 4,000 people to have ridden on this street today. Good job, and thank you for not contributing to our growing car traffic congestion problem as well as pollution emission!”
