Your city’s Schelling point

Not a selling point, but a Thomas Schelling point. Also known as focal point, a segment of game theory. Without communicating, how will two people make the same choice?

To illustrate (based on Thomas Schelling’s own example, and Yuri Artibise, who inspired this post), I ask you this question:

If I called you and asked you to meet me in downtown [your city] in an hour and then my phone’s battery died, where would we meet?

Yuri said “According to Adam [Greenfield], most cities have Schelling points, because, without effective communication between people (i.e., cell phones), meeting places ultimately converge on a couple of high visibility—and usually iconic—destinations.”

It seems for New Yorkers, the traditional answer has been at the information booth in the Grand Central Station main hall. Yuri suggests that “there is nothing inherent about Grand Central Station that makes a particularly desirable meeting place.”

Schelling’s theory explains why people might pick the same location. Contributors to the “focal point” article on Wikipedia write this:

Consider a simple example: two people unable to communicate with each other are each shown a panel of four squares and asked to select one; if and only if they both select the sameone, they will each receive a prize. Three of the squares are blue and one is red. Assuming they each know nothing about the other player, but that they each do want to win the prize, then they will, reasonably, both choose the red square. Of course, the red square is not in a sense a better square; they could win by both choosing any square. And it is the “right” square to select only if a player can be sure that the other player has selected it; but by hypothesis neither can. It is the most salient, the most notable square, though, and lacking any other one most people will choose it, and this will in fact (often) work.

The destination choice should change with context. If you were to meet a classmate on campus, you might meet in the building where the class you share meets.

Benefits of bike parking

I’m working on my master’s project about bike parking distribution and equity in Chicago and while working on a section in the paper, I decided to get some help from readers. Many transportation projects are measured on predicted changes like trip travel time savings or trip cost savings (I give two examples below the photo).

My question is this: What are a bike parking installation’s measurable benefits to a traveler or a community?

To figure equity (fairness) for these project types, you measure these impacts for different groups (often high, medium, and low income), either in the alternatives analysis, or project selection phases. So, converting a lane on a highway to charge tolls for the lane’s users will have a certain benefit for many trips: a lower trip time. A new bus route may be convenient enough for some travelers to switch from driving to taking the bus, possibly reducing their trip cost.

High-speed rail wrap-up

So let’s recap the week of high-speed rail announcements.

On Wednesday (1/27), President Obama in his State of the Union speech talks about how $8 billion in funding for high-speed intercity passenger rail (HSR) will be a major jobs creator.

Photo: Tri-Rail is a commuter rail service between Miami, Fort Lauderdale, and Palm Beach. In five years, a high-speed train will whisk travelers between Tampa and Orlando. The hope is that a second link between Orlando and Miami will come afterwards.

The next day, in Tampa, Florida, he announced the winners of the $8 billion dollars of funding. Actually, the White House Press Office “leaked” the press releases the night before.

So what did I do for “high-speed rail week”?

I wrote a few articles and created a couple summaries:

Simple & successful bike parking

Not every concept, skill or tool can be further and further simplified. Does anything really take just 3 steps?

  1. Set it
  2. Forget it
  3. No third step! (This article is about bike parking, not Ron Popeil’s Showtime Rotisserie!)

I believe I can simplify bike parking. Here are my two rules to have successful and well-used bike parking:

1. Put bike parking as close to the front door as physically possible. I can’t tell you how many times I’ve seen bicycle riders use a substandard sign pole or tree instead of a high-quality bike rack because the bike rack was an additional 20 feet from the front door.

UPDATE: As Dave Reid points out in the comments below, close parking increases security. Additionally, I’ve now written about the phenomenon where people lock to inadequate fixtures when high-quality bike parking is nearby, what I call “Bike Parking Phenomenon A” or the “50 feet rule.” Every foot makes a difference!

Kuma's Corner
The bike parking in this photo sits only 20 feet away from the front door to a popular Chicago, Illinois, restaurant called Kuma’s Corner.
Bike parking phenomenon A (50 Feet Rule)

The bike parking in this photo is too far away from the Whole Foods store entrance for bicyclists to consider using it.

2. Choose the right bike rack. How do you know? Give bicycle riders a bike rack that’s easy to use and secure (i.e. don’t let the bike rack be the weak point in the bicycle’s security).

The U-rack (also known as inverted U-rack, staple rack, and Sheffield stand) is the best design out there. Some variations, like the one at the top of the post, are acceptable. Square tubing is preferred because it cannot be cut by a $5 pipe cutter.

Kuma's Corner

Six u-racks (also known as inverted-u, or staple racks) line the sidewalk in front of Kuma’s Corner in Chicago, Illinois.

If these two tips aren’t good enough, read through the online brochure, Bicycles at Rest, from the Capital Bike & Walk Society, in Victoria, British Columbia, Canada.

Rep. Mica of Florida is confused about how best to support high-speed rail

From Associated Press writer Joan Lowy’s article, “White House doles out $8 billion for fast trains,”

Rep. John Mica of Florida, the senior Republican on the House transportation committee, complained that the Midwest lines awarded grants will achieve top speeds of only 110 mph and were “selected more for political reasons than for high-speed service.”

No, John, the Midwest was selected because it had a comprehensive plan with a regional approach, and with all Midwest states on board a collaborative effort to make Chicago the hub of an expansive network of fast trains that go to many, desirable destinations.

The Midwest was also selected because many of the Amtrak routes showed increased ridership over the past three years (2006-2009), and the ones that received a higher state subsidy or targeted improvements (with funding from the states) that reduced travel time and increased reliability showed an especially high increase in ridership.

And excuse me, Florida received a lot of money for a high-speed train between Tampa, Orlando, and Miami.
