Free high resolution maps of Chicago on which to draw

November 28, 2012 / / 0 Comments

For a Grid Chicago article I was writing, I wanted to draw on a map to demonstrate to readers where people were commuting and not commuting. I wanted the map to show CTA lines. I didn’t want to use a Google Maps screenshot because it would have been low resolution, and I didn’t think the styling would be appropriate.

I opened up TileMill and whipped up my own maps! I already had the base layers set up for the Chicago Bike Map app, so I duplicated that project and then added the Chicago Transit Authority and Metra train lines with data and styles prepared by OpenPlans (created for its Chicago bike sharing Shareabouts installation; download the data and styles here). Highways, the most common geographic reference point in cities, are also included on the map.

Data comes from OpenStreetMap contributors and the styling is OSM-Bright.

Go grab them on Flickr. Use them as needed but please provide attribution to “Steven Vance, OpenPlans, and OpenStreetMap contributors”.

New Honda commercial tells people it’s okay to drive their car while sleepy

October 31, 2012 / / 10 Comments

Eff you, Honda.

Partial transcript:

We know you.

[Shows guy yawning.]

We know you have to rise early and work late.

[Shows someone drinking coffee. Shows “Lane Departure Warning” signal and an obscured person driving on a rural road driving their Honda Accord in the opposite direction lane, then swerving back into the correct lane.]

With not enough sleep in between.

[Shows hands of driver moving the steering wheel to maneuver the car back into the correct lane with driver’s shoulders moving dramatically to either show that the steering wheel had to be yanked or that he’s shrugging off the moment.]

The rest of the commercial shows different features and makes stupid comments about your needs and desires.

It’s not okay to drive in that condition.

Is there a member of the ITE who will stand up against bad road designs?

October 1, 2012 / / 25 Comments

Sharing the road is one place to start. Why should one on a two-wheeled, muscle-powered device pedal along side a garbage truck with blind spots? Wait, why does an automobile even have blind spots? This enormous right-turn lane is one example of “dangerous by design”. 

Update October 5, 2012: For a great example on why I cannot – and why you should not – support bad road designs is this story of a fatal bike crash on a major biking “commuterway” in Chicago. We must stop building narrow bike lanes to the left of parked cars and we can be done with this type of crash for good.

The infrastructure as we have it in Chicago and many other American cities cannot support any increases in bicycling. The operation and design of our infrastructure creates a finite limit for the number of people who will bicycle on it. I’m not talking about how many people can use it, but how many people want to use it.

We’ve seen infinitesimal growth in the bicycle’s mode share for commuting to work, so small that the growth might not actually be growth at all because all the reported increases are within the range of error (the Census Bureau being the collector and distributor of the data). Our infrastructure is not safe, and that is what inhibits an increase in bicycling riders and trips that the City of Chicago, its mayor, its council, its officially adopted plans, and its people, desire. Until our roads are made safe, the cycle growth will remain minuscule or non-existent. The only other significant factor in promoting cycling is high gasoline prices, but even as they remain high, the cycle growth (or spike, seen in 2008) hasn’t returned.

It’s a small group of people who are designing and maintaining our roads. And they are the first group of people we listen to when we say we want safe roads. Instead of the people who’ve actually built safe roads.

The ITE is the Institute of Transportation Engineers, and, like many organizations, has a code of ethics. In their Canons of Ethics document (.pdf), there are at least two sections that require members to stand against bad road designs.

Section 1: The member will have due regard for the safety, health and welfare of the public in the performance of professional duties.

Section 11: The member will guard against conditions that are dangerous or threatening to life, limb, or property on work for which the member is responsible, or, if not responsible, will promptly call such conditions to the attention of those who are responsible.

A study in Portland, Oregon, found that 60% of residents wanted to bike, but had concerns about safety.

These residents are curious about bicycling. They are hearing messages from a wide variety of sources about how easy it is to ride a bicycle in Portland, about how bicycling is booming in the city, about “bicycle culture” in Portland, about Portland being a “bicycle-friendly” city, and about the need for people to lead more active lives. They like riding a bicycle, remembering back to their youths, or to the ride they took last summer on the Springwater, or in the BridgePedal, or at Sun River, and they would like to ride more. But, they are afraid to ride. They don’t like the cars speeding down their streets. They get nervous thinking about what would happen to them on a bicycle when a driver runs a red light, or guns their cars around them, or passes too closely and too fast.

American roads are dangerous by design. It’s time to fire the people who design them that way.

Year after year, roads in Chicago are ripped up, repaved, and restriped in exactly the same way that existed before. Miles of missed opportunities for safer roads. This essay says nothing of the lack of police enforcement of traffic rules, for which there is little empirical evidence. The essay may be updated from time to time, but I won’t be noting each change.

An example of a better design: the buses and bikes don’t mix, and automobiles turning left cannot be passed by through-automobiles. Bicyclists are safer. 

The United States uses way too much text for regulatory traffic signs

September 19, 2012 / / 21 Comments

Look at these two signs in Berlin (right outside the American embassy). They’re universal across the European Union – and probably in adjacent non-EU countries. The upper one means “yield” and the lower one with the white arrow means “compulsory right turn”. In the United States, there are several signs that mean the same thing. The simplest one we have comes in two forms: symbol and text. That makes two different signs, but there’s a third one. It’s also a text sign but has extra words!

American symbol sign (actually a symbol with text): The sign has an arrow pointing in an upward curve toward the right and the word “only”. Photo by Joseph Dennis. 

Yet there is no need to mix a symbol and a word, as both parts of the message (“right turn” and “only maneuver you can make here”) can be communicated with symbols. In the EU, the right turn sign has two states, both depicted by symbols: off and on. Off meaning you cannot turn right there and is depicted with an arrow pointing right, on a white background, circumscribed with a red circle. The “on” version means you must turn right there and is depicted with an arrow pointing right, on a blue background. (It would be pointless to have a sign saying you can turn right somewhere.)

The next sign is the text-only version of the “right turn only” sign.

And then there’s the most ridiculous one, “right lane must turn right”. In many places, Chicago included, bikes and buses are excepted.

A group of people protest the stupidity of this sign design. I mean, a bunch of Tea Partiers protest our socialist road system. Or something. Photo by Susan Adams. 

All of the signs depicted above mean the same thing! Why have we developed four unique ways to communicate a single meaning?

While I’m on the subject of right turns, here’re two signs in San Francisco, on Market Street at Octavia Boulevard. Octavia is the end of the Central Freeway, so people driving here are in the mindset of fast highway driving. Cars cannot be turned right here and bicyclists are warned to look out for people making illegal right turns. In other words, “Beware car drivers who break the law”.

Brief history of suburbs and sprawl, according to Taras Grescoe’s “Straphanger”

June 29, 2012 / / 0 Comments

The Metra station in Riverside, Illinois, a version 1.0 streetcar suburb designed by Frederick Law Olmsted and Calvert Vaux. 

I’m reading another book a publisher sent to me. It seems pretty biased, and it’s biased in the direction I already feel, so it’s really easy reading. But it seems that people like me are its only audience and that it assumes I’m already pro-cities, anti-suburbs and maybe even anti-car. Definitely not a book that’s going to espouse the benefits of transit to those who don’t use it, don’t want to use it, or are on the fence for either situation.

If I could get my father or brother to read this book, that would be an accomplishment just short of a miracle.

The book is Straphanger: Saving our cities and ourselves from the automobile, by Taras Grescoe. I really like the section I just finished reading, a “condensed history of sprawl”. I had recently “argued” with my father about the development of the subdivision he lives in, east of Phoenix. He posited that suburbs were the result of consumer desires. Grescoe writes to the contrary. Here we go:

The origin of the Anglo-American suburb has been traced to Clapham, five miles south of London, where, in the 1790s, Evangelical Christians eager to remove their families from the evils of the city began living in what had formerly been their weekend villas, and commuting to the City by private carriage. In the United States, [author Kenneth] Jackson dates the beginning of the process to 1815, when regular steam ferry service to Manhattan made Brooklyn Heights the nation’s first true commuter suburb. (page 89)

American suburb version 1.0

  • When: 1853 onward
  • What it was: picturesque, full of green space, near central cities, attached by rail line
  • Who lived there: As mortgages didn’t exist, only those who could afford to buy a home outright
  • Examples: Llewellyn Park, NJ; Riverside, IL.
  • Note: Ebenezer Howard’s “Garden City” design is related.

American suburb version 2.0

  • When: Post World War II
  • What it was: cheap, small housing on vast land tracts; pre-assembled homes
  • Who lived there: Families with soldiers that expanded quickly so new homes were needed fast.
  • Examples: Levittown, Long Island; Lakewood, Los Angeles.
  • Note: “The prevailing myth”, writes Kenneth Jackson, “is that the postwar suburbs blossomed because of the preference of consumers who made free choices in an open environment. Actually, most postwar families were not free to choose among several residential alternatives. Because of public policies favoring the suburbs, only one possibility was economically feasible”.

American suburb version 3.0

  • When: Late 1980s, 1990s to now
  • What it was: Found near office parks, also known as “edge cities”, “common interest communities” (gated and homeowners associations)
  • Who lived there: Single races (self-segregating), people who lean conservative
  • Examples: Silicon Valley, Nevada, Florida
  • Note: Under the George W. Bush administration, Fannie Mae and Freddie Mac offered easy credit and homeownership rate rose to 69% by 2004. “(By 2012, it is expected to drop to 62%, the lowest level since 1960.)”

American suburb version 4.0

  • When: 2008, easy credit crisis, underwater mortgages
  • What it is: Least glamorous, the clichéd image of the inner city has moved to the suburbs. Arizona has highest rate of property crime. Nevada and Florida, the most suburbanized states, have highest rates of violent crime (Florida also has highest rate of pedestrian and bicycle fatalities).
  • Who lives there: A diverse group of people.
  • Examples: See “What it is”
  • Note: “Humans are social animals. I [Kenneth Jackson] think the biggest fake ever perpetrated is that children like, and need, big yards. What children like are other children. I think we move children to the suburbs to control the children, not to respond to something the children want. In the city, the kids might see somebody urinate in public, but they’re much more at risk in the suburbs, where they tend to die in cars.”

What are those public policies as described in American suburb version 2.0?

The federal government had carrots and sticks. Carrots were subsidies for homeownership (could be deducted from income taxes) and no down payment required for returning soldiers. Sticks included redlining (racial segregation), propagated by the Federal Housing Administration and banks. Zoning was another stick, which dictated what could go where.

Another carrot was the federally-funded highway system, the “greatest public subside to private real estate in the history of the world”.
