Quotes about transportation equity

February 12, 2010 / / 0 Comments

My master’s project involves a discussion about equity. Equity of bike parking distribution is the main focus of my project.

I picked up some great books at my school’s library. Here are some selected quotes (many of which I’ll use in the project’s paper).

  • “Transportation improvements distribute nonuniformly over space, implying that they affect diverse populations disproportionately” (Berechman).
  • “Geography defines the contours of the equity analysis in two important ways. First, since investment in transportation infrastructure is geographically specific, there is inherent competition and conflict between places” (Hodge).
  • The “costs and benefits of transportation policies may take place in different time periods” (Bae and Mayeres). For example, “mega projects are often built with excess capacity aimed at satisfying future needs. Such a pattern imposes inequitable intergenerational transfers, favoring the future rather than the present generations” (Berechman).
  • “Indirect benefits…represent real impacts that probably benefit some people more than others. It is exceedingly difficult, however, to trace through the benefit stream of these broad impacts” (Hodge).

And my favorite: “Transportation is an unusual public service in that it is not consumed for its own sake but, rather, as a means to another end. Thus, the value of the service depends primarily on how well it provides access to other places” (Hodge).

My professor last semester said the same thing, actually, and then we had a huge discussion trying figure out situations where this isn’t true. The only thing our class (well, the professor himself) could come up with was joyriding (driving aimlessly in a car). But is joyriding really transportation? The trip origin and destination are the same and the trip has no purpose.

I thought of the transportation system at Walt Disney World, but I eventually withdrew my support – although the goal of that system is to make it easy for guests to spend more money, the system has a legitimate role in giving access to places inside and outside the “pay area.”

Your city’s Schelling point

February 10, 2010 / / 0 Comments

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.”

Seattleites, might you meet your friend at the Central Library in Seattle, Washington? Photo by Dolan Halbrook.

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

February 2, 2010 / / 0 Comments

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

January 29, 2010 / / 0 Comments

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:

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

January 28, 2010 / / 0 Comments

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.
