A very eclectic mix of things I find interesting. Mostly about urbanism, with a slight focus on street art, transportation and bike issues. But I also sometimes post other random stuff.

Woah. 3D printing took on a whole new level of coolness for me: 3D-printed titanium bike parts. (And there’s a pretty sick video to go with it too)

Saudi bicycle ban lifted: Women can now bike, with certain restrictions
“Saudi women can now legally bike in public, under certain conditions. On Monday, Saudi Arabia’s Commission for the Promotion of Virtue and the Prevention of Vice overturned a previous ban on cycling and motorbiking for women. The ruling stipulates that women must wear a full-body abaya, be accompanied by a male relative, and stay within certain areas. They are allowed to bike for recreational purposes only, not as a primary mode of transportation.”

Actor Wendell Pierce Opens Grocery Stores in New Orleans Food Deserts
The stores offer fresh and healthy food, and offer rides home if you spend more than $50.
I’m not sure how I missed this awesome Kickstarter until now (granted, it’s only 10 days old, but apparently it’s been featured all over online): it’s a GPS tracker for your bicycle, with an open API, tamper detection and automatic crash reporting. “The BikeSpike is backed by the world’s smallest GPS chipset with a built-in antenna, an on-board accelerometer, and a connection to a global cellular network.” What this means is that you can digitally “lock” your bike (geofencing) and get notified if your bike moves from its spot, monitor its location on a map using a computer or phone (native iOS and android app included) and share said location with law enforcement or friends - a feature you can also do use for fun, when racing etc, or to monitor your children and get notified when they ride out of their safe zone.
But here’s the best part: it’s going to have an open API!
This solves about half a dozen bike problems I’ve brainstormed with others at various hackathons and unconferences, like RHoK and TransportationCamp. The collision detection system & police report creation (I wonder how folks like Bike Safe Boston and Bike Safe Nation could leverage this), being able to share your bike’s location (oh, the possibilities! Like social bike commuting apps for bike trains. Or initiatives like Cycle Atlanta or CycleTracks in San Francisco and a bunch of other cities), road quality reporting, fitness apps (although, aren’t there already plenty enough of those?) etc etc.
Only thing I’m wondering, regarding the bike theft & recover aspect of the product: I know they say it’s got tamper detection, but it seems like it wouldn’t be that difficult to remove the device from the bike when you’re stealing it… right? Especially if you’re already stealing a bike anyway.
NPR story about kids’ need to exercise ends up being about biking, traffic, and urban planning
Today NPR’s Morning Edition had another installment in their series On the Run: How Families Struggle to Eat Well and Exercise,
What I found really interesting is that this story, which was supposed to be about how parents struggle to make sure their kids get enough exercise, ended up being about biking, traffic, and urban planning. One mother talked about how she spends her afternoons in Los Angeles traffic, ferrying her two boys from one sporting activity to another. She explained that her eldest can’t really just bike around in her neighborhood because it’s not bike-friendly enough. The story also profiled two other moms, both in Portland, and I especially loved how both talked about the choices we make for ourselves, for our families, for our cities (emphasis is mine)
Fahrner and her family bike, walk or take public transportation everywhere. For them, exercise is something that happens as they live their daily lives, not something they schedule. Fahrner doesn’t even own a car.
“We basically mapped out where the schools are, where hospitals are, where places to shop are, and so we very conscientiously picked a neighborhood where we can walk to all these things,” she says
So when Fahrner is scheduling activities for her 10-year-old son, she looks at what’s available in her neighborhood, choosing sports at local parks and community centers.
She and her husband used to work 70-hour weeks in the high-tech industry in California, but when their son was born they decided to simplify their lives and moved to Portland.
“It’s a choice you have to make, and, yes, it’s hard obviously,” she says. “You need to look where your job is. But if you cut down your commute from two hours to one hour, you are much happier because you have more time for yourself … and your kids.”
Janelle McAvoy and her family are making the same kind of choices. She bikes to the grocery store with her 4-year-old daughter, Clover, in a trailer and sons Jack, 6, and Everett, 8, on their bikes.
[…]
And while she acknowledges that Portland is particularly pedestrian- and biker-friendly, McAvoy believes it’s because of the choices people here are making.
“If people drive more, there’s going to be the bigger parking lot and more space on the roads. If people walk more and ride their bikes more, [there will be] more bike racks because that’s what the people want,” she says.
Wow. When I saw this, at first I was like, beautiful visualization & animation. Then I was like, cool, I can segment the data by gun, victim’s ethnicity, gender, age, location etc. And then I accidentally hovered over a line and I was like, WOAH, each line provides details for each of the nearly 10,000 people killed by guns in 2010 in the US, including their age, gender, race, relationship to killer, and more.
Two thoughts:
- Filter the data for women and hover over the lines. Almost all of them were shot by their husband, boyfriend, or exes. I’ve heard the stats about how violence against women is almost always perpetrated by someone the victim knows, but to see it like this, and to this extent… just, wow. Seriously, can we talk/do something more about domestic violence pls?
- According to my inbox, I first heard and starred an email about visual.ly 18 months ago, when it opened for public beta. Man, I really need to get better at getting around to those emails, bookmarkets etc. How have I not checked this out more by now?? Also, thanks to this visualization, I also found out about Periscopic, a “socially-conscious data visualization firm that helps companies and organizations promote information transparency and public awareness.” With all the reading I do on Upworthy, how had I not heard about these guys yet?? Or have I but I wasn’t paying attention? Either way, *swoon*
tl;dr: Check out the visualization above, filter by women, hover over the lines. Check out visual.ly and Periscopic.
3 events this Thursday of interest to nerds about cities, and Atlanta in particular
That would be Thursday, February 7th, 2013:
- First Atlanta Studies Meet Up. These quarterly meetings will showcase 2 Atlanta focused projects and bring together a group of folks interested in our city.
Hannah Palmer will present a mapping project created from her research on places destroyed by Atlanta’s airport. Her book, “I’m From Here,” is about going home again, or what’s left of it. Many of the locations explored and documented in the book have been nearly erased from existence, so she created a map. An Atlanta native, Hannah Palmer is an artist and writer who is interested in the intersection of southern stories and urban landscapes.
Michael Page and Randy Gue will present on a project at Emory’s Digital Scholarship Commons (DiSC) to create an application similar to Google Maps for Atlanta from the late 1920s through the early 1950s. Users will ultimately be able to add layers and tag attributes to a series of addresses in the historic city. This combination of GIS technology and unique datasets will change the way Jim Crow Atlanta is studied by allowing researchers to visualize social changes over time.
Over the next few years, Atlanta’s Ponce De Leon Avenue is slated for several road improvement projects which will enhance roadway efficiency and expand mobility options for pedestrians, cyclists and vehicles on the facility. Proposed improvements include roadway resurfacing, lane reconfiguration, ADA accessibility upgrades, connectivity to the Beltline and improved access to existing public transportation service. Improvements will be concentrated between Juniper Street and Briarcliff Road/Moreland Ave with street resurfacing extending beyond this scope. The City of Atlanta and Atlanta BeltLine are partnering with the Georgia Department of Transportation to coordinate these projects.
- BeltLine Run Club (happen about once/month - the February run will mark the one year anniversary of the run club!)
Join us for a 4 mile run as we head down the Eastside trail toward Irwin Street and back towards Park Tavern for some light appetizers, beer and fun! The Run/Walk will leave at 6:30pm and we will be meeting in the meadow behind Park Tavern.
ATL Urbanist: Visualizing data from CycleAtlanta app
Poster dedwards8 shared some excellent maps of cycle routes via Reddit. According to the post, these are maps that are created from “data entered by people using the CycleAtlanta app.”
The maps are a product of the “Transit Day Hack-a-Thon at Georgia Tech last week.”
