KurzweilAI shows the press release from Volvo: Volvo’s autonomous cars travel 124 miles in Spain in ‘road train’
[This is interesting technology, I am glad they got it to work technically. I still want and expect autonomous robot cars.]
A podcast makes today’s Linklist: Horace Dediu on The Critical Path #40: Awaiting the Big Bang:
“This week, Horace follows up on his discussion of automobiles and road infrastructure by talking about how road networks were rebuilt in European countries to accommodate cycling. That leads to hints about the challenge of re-building energy infrastructure to support new power train technologies. Finally He and Dan also analyze comments made by Tim Cook at the recent D10 conference about Apple TV and disruption of the entertainment industry.”
Colin Harris @ streets.mn: Open Streets 2012 is Back:
“Following the inaugural Open Streets Minneapolis event in June of 2011, Minneapolis residents will have another opportunity to explore and enjoy their neighborhood streets without the presence of motorized traffic on June 10th, 2012. Open Streets events (based on the Ciclovía from Bogotá, Colombia) bring together families and neighbors to bike, walk, socialize, play and shop in their communities in a safe, car-free environment.”
Recently published, and summarized in CTS Research E-News: Using accessibility to evaluate future planning scenarios:
“Understanding the interdependent relationship between transportation and land use is important for planning the future growth of cities. Recognizing how this relationship affects accessibility—the ability of people to reach the destinations that meet their needs and satisfy their wants—can help policymakers and planners make decisions that optimize a city’s efficiency, livability, and economic competitiveness.
In a study funded by the Minnesota Department of Transportation, researchers from the Department of Civil Engineering compared a set of planning scenarios for the Twin Cities metropolitan area using accessibility as a performance measure. Associate Professor David Levinson, undergraduate research assistant Paul Anderson, and graduate student Pavithra Parthasarathi used the scenarios to evaluate the accessibility of various land use and transportation network combinations.
The researchers analyzed the accessibility of 60 different scenarios, including combinations of six land-use scenarios and 10 highway and transit networks. The land-use scenarios included existing 2010 conditions, projected 2030 conditions, and various combinations of centralized and decentralized population and employment conditions.
Highway networks used in the scenarios included 2010 conditions, projected 2030 conditions, an ideal freeflow network with no congestion, and a hypothetical diamond lane network that added high-occupancy toll lanes to all freeways inside the I-494/694 beltway. Transit networks ranged from 2010 conditions to projected 2030 conditions to a ‘retro’ network that added all 1931 rapid transit streetcar routes to the 2030 network.
In terms of land use, results show that centralized employment and centralized population had the highest accessibility across all networks, resulting in more access to jobs and labor as well as shorter commute times. The researchers found that fully centralized growth produced about 20 to 25 percent more accessibility than the projected 2030 scenario, depending on the accompanying transportation network.
Of the transportation networks, the researchers found that the freeflow network had the highest accessibility—20 percent more than the projected 2030 network—followed by the diamond lane network.
At first, the researchers say, it would be easy to choose the land use and transportation network combination with the highest accessibility as the future planning goal. However, the scenario of centralized population and employment on a freeflow network—while ideal for accessibility—is not likely to be cost-effective or feasible under current conditions.
Instead, the researchers say, these study results could be used to help prioritize future investments and land-use strategies based on how accessibility-effective they are—how much accessibility they deliver per dollar of investment.
A final report on the project, Using Twin Cities Destinations and Their Accessibility as a Multimodal Planning Tool (MnDOT 2012-05), is available on the CTS website.”
Reason: Lessons From the United Fruit Company – Reason.com discusses the new book by Rich Cohen, The Fish That Ate The Whale: The Life And Times Of America’s Banana King.:
“There is the efficiency. Zemurray got started in the banana business by figuring out how to distribute ‘ripes,’ the freckled bananas that were thrown away as useless discards before Zemurray figured out the logistics of fast-moving rail distribution.”
[United Fruit was also one of the early investors in RCA, as they held key radio patents, which were crucial for banana distribution.]

Bryan Caplan @ Econlog: A Signaling Theory of Suboptimal Telecommuting, :
“A fascinating senior paper by Georgetown undergraduate Alexander Clark suggests that the answer is yes. Clark’s story: Workers physically commute for signaling reasons. Employers can monitor your productivity better when you actually come to the office. Workers who telecommute put themselves on the slow track to success – if they can even get hired in the first place. To bolster this thesis, Clark analyzes the American Time Use Survey using the employer learning-statistical discrimination (EL-SD) framework. He finds that the labor market does indeed take longer to reward telecommuters for their hard-to-observe abilities. “
[Not only does telecommuting signal sloth, there is at least one survey cited which shows telecommuters don't work as many hours per day.]

From JW: Green Car Congress: Google’s technology campaign for autonomous driving:
“Search engine giant Google is looking for partners within in the auto industry to help launch one of the most significant applications of artificial technology over the next several years, the self-driving car.
In a keynote address to the SAE 2012 World Congress on 25 April 2012, Anthony Levandowski, Business Lead for Google’s Self Driving Car Project provided an overview of Google’s autonomous vehicle program and requested that the auto industry partner with Google on the implementation. (Levandowski joined Google in 2007 to launch StreetView—Google Maps with Street View lets you explore places around the world through 360-degree street-level imagery.)
We’re not perfect; the technology is nowhere near ready. We want to set expectations low but we want to encourage dialogue on how we want to move the technology forward.
‘For some, driving is a distraction.’
—Allen Taub, former GM VP, Global R&D
Levandowski shared that 32,788 people were killed in the US last year in auto accidents and 90% of those accidents were related to human error. Multi-tasking while driving is only increasing to the extent that people view driving as the distraction. Twenty percent of the food consumed in America is eaten in cars. Google believes that a future state with having computers drive cars can ‘remove a gigantic chunk’ of the US fatalities.
Approximately 1.5 million people/year are killed in auto accidents globally. Google is involved because the company has a strong technical legacy and the company likes to take on problems where the ‘solutions have a high impact on humanity that involve challenging technical problems’.
In addition to the safety impact, Google believes your brain should be able to engage in activities other than driving.
It is a bug, not a feature, that you need to drive all of the time…What if I gave you a pill that allows you to get 10% longer life without any side effects …given how much time we spend in a car, a self driving car is that pill.
SA: Why America’s Love Affair with Cars Is No Accident: Scientific American:
“The change in American public opinion from thinking of cars as wildly dangerous vehicles to having a ‘love affair with the automobile’ was no accident. Instead, it reflected a serious push by the car industry to change people’s psychology. Automobiles had to win the battle for hearts and minds before they could take over streets where people had once swarmed.”

I know from reading your blog that you are a bit keen on anthropomorphized transportation. This week I stumbled upon an old cartoon celebrating the 50th anniversary of the Wuppertal Schwebebahn from 1951. The “Laughing Schwebebahn” is not only smiling, but it also has wings. It’s from Das Beste von der Schwebebahn in 50 Jahren (http://www.worldcat.org/title/beste-von-der-schwebebahn-in-50-jahren/oclc/8757312).
See wikipedia for more.
I am guessing this category (anthropomorphic monorails) is smaller than others, but please send in any other examples.
