	         <title>Road deaths cost world economy $540b </title>
         <description><![CDATA[<p>From Australia's ABC <a href="http://www.abc.net.au/news/stories/2009/11/20/2748245.htm?section=world">Road deaths cost world economy $540b</a></p>

<blockquote>
Road deaths cost world economy $540b
By Moscow Correspondent Scott Bevan

<p>Posted 1 hour 28 minutes ago</p>

<p>Government ministers and traffic safety campaigners from around the world are meeting in Moscow in a bid to reduce the global annual road toll.</p>

<p>It is estimated 1.3 million people die on the world's roads each year.</p>

<p>So far this year there have been 168,000 traffic accidents in Russia alone, killing 21,300 people and injuring 212,500.</p>

<p>The meeting has been billed as the first global ministerial summit on road safety, prompted by the enormous impact crashes have on lives and economies around the world.</p>

<p>Russian president Dmitry Medvedev says road crashes drain the global economy of $US500 billion ($540 billion) a year.</p>

<p>As well as sharing information, summit participants are expected to sign a declaration calling for a decade of action for road safety.</p>

<p>Australia's Federal Department of Transport delegate Joe Motha says the declaration could help focus efforts and coordinate know-how to tackle the problem.</p>

<p>"It's not an issue that's a knowledge issue, it's more an issue of implementing what's already known," he said.</p>

<p>Campaigners from the Commission for Global Road Safety estimate a decade of action could save five million lives.</p>

<p>Tags: disasters-and-accidents, accidents, road-accidents, safety, russian-federation<br />
</blockquote></p>

<p>One of the interesting aspects of this came up in CE5212 class on Wednesday, which is insurance. Traffic crash damage (including both bodily damage and property damage) costs are borne by the victims, and, in the US, a multitude of insurance companies, but traffic crash prevention are borne by the road agency. </p>

<p>No single individual or insurance company has the incentive to improve road safety. I cannot personally spend money to improve a road which is only one of many I travel on, and an insurance company will not do that if they only get a fraction of the benefits (safety improvements for their customers).</p>

<p>However, it is clear, society would benefit from improvement in road safety. How to align interests. A solution comes from Australia itself (home to this article), wherein the <a href="http://en.wikipedia.org/wiki/Transport_Accident_Commission">Transport Accident Commission</a> is the statutory insurer of third party liability in Victoria, Australia. That is, Australia has socialized car insurance, and has since at least 1986.</p>

<p>The question is, are Australia's Roads safer? Evidence would seem to suggest yes. A <a href="http://books.google.com/books?id=iY5RrUKTkeQC&pg=RA1-PA37&lpg=RA1-PA37&dq=traffic+fatality+rates+australia+united+states&source=bl&ots=vb2z2gkDEp&sig=layMu3UO8nazHB07YpZBiBMNQo0&hl=en&ei=zoAES_m4Bs3Onge2lMF2&sa=X&oi=book_result&ct=result&resnum=3&ved=0CBQQ6AEwAg#v=onepage&q=traffic%20fatality%20rates%20australia%20united%20states&f=false">study by the World Health Organization, now in Google Books (World report on road traffic injury prevention By M. M. Peden, World Health Organization)</a> (Figure 2.4)<br />
shows that while the Australia and US traffic fatalities per 100,000 population were quite simlar through the 1980s, since 1986, Australia's rate has declined faster than the US, to the point that Australia's rate is less than 2/3 of the US rate. In other words, if the US progressed as much as Australia, last year's US death toll on the roads would be less than 25,000 instead of 37,261 (US number for 2008), (<a href="http://www-nrd.nhtsa.dot.gov/Pubs/811207.PDF"> source</a>). Commercial vs. state auto insurance may not be  the only difference, but it is an important one.</p>]]></description>

	         <title>Nissan&apos;s Electric Leaf Spreads the EV Gospel</title>
         <description><![CDATA[<p>From Autopia <a href="http://www.wired.com/autopia/2009/11/nissan-leaf-national-tour/">Nissan's Electric Leaf Spreads the EV Gospel</a></p>

<blockquote>
... You'll own the car. Nissan will own the battery.

<p>Ghosn said leasing batteries -- which Nissan will produce through a joint venture with NEC -- provides several benefits. First and foremost, it keeps the cost of the car reasonable. Although automakers don't discuss what their batteries cost, they are widely believed to run $500 to $1,000 per kilowatt-hour. The Leaf sports a 24 kilowatt-hour lithium manganese battery.</p>

<p>By retaining ownership of the battery, Nissan also can update them as technology advances so consumers aren't left with "last year's model." And though Ghosn didn't mention it, leasing provides Nissan with some cover should the battery wear out prematurely because it can just replace the pack.<br />
...</p>

<p>Ghosn didn't say what the lease might cost but said Nissan is confident the cost of the lease, plus the money you'll pay for electricity, will for most consumers be no more expensive than buying gasoline. When we drove a Leaf development prototype in April, a company exec said the cost per mile is 4 cents if you figure gas is four bucks a gallon, electricity is 14 cents a kilowatt hour and you drive 15,000 miles a year. Nissan said at the time the car would cost about 90 cents to charge if you plug it in off-peak.</p>

<p>The Leaf's air-cooled battery provides enough juice to go 100 miles in city traffic.</p>

<p>...</p>

<p>Plug the car into a 110-volt socket and you'll need 14 to 16 hours to recharge it. A 220-volt 20-amp line cuts that to seven or eight hours, while a 440-volt "quick charge" station will get you to an 80 percent state of charge in 25 minutes, Dominique said.</p>

<p>The Leaf is based on a heavily modified version of the platform underpinning the Versa and the two cars bear more than a passing resemblance. </p>

<p>...</p>

<p>Nissan plans to offer the car for "between $26,000 and $33,000″ when it goes on sale in December, 2010. </p>

<p>...</p>

<p>Nissan's plant in Oppama, Japan has the capacity to crank out 50,000 Leaf cars annually, and Nissan is using a $1.6 billion federal loan to build an EV and battery plant at its North American headquarters in Smyrna, Tennessee. When the factory opens in 2012, it will be able to produce 150,000 electric cars and 200,000 battery packs annually.</p>

<p>...</p>

<p>"I think I'm being conservative saying 10 percent" of the market will be EVs by 2020, Ghosn said. ...</p>

         <description><![CDATA[<p>From NYT<a href=http://roomfordebate.blogs.nytimes.com/2009/11/03/buffetts-bet-on-trains/>Buffett's Bet on Trains</a><br />
<blockquote><br />
Warren Buffett is betting big on railroads. He started buying Burlington Northern Santa Fe in 2006 and then made investments in Union Pacific and Norfolk Southern. On Tuesday, his company, Berkshire Hathaway, announced the purchase of the 77 percent of Burlington Northern it didn't already own for about $44 billion (along with the assumption of $10 billion in debt). It is Berkshire's largest acquisition.</p>

<p>It has been a long time since railroads were central to America's booms, bubbles and busts. What does Mr. Buffett's investment in trains say about prospects for the economy? How can his role be put in historical perspective?<br />
</blockquote></p>

<p>Nice discussion ensues.<br />

	         <title>Is green U.S. mass transit a big myth?</title>
         <description><![CDATA[<p>From PG: A blogpost by Brad Templeton: <a href="http://www.templetons.com/brad/transit-myth.html">Is green U.S. mass transit a big myth?</a></p>

<blockquote>
...
These studies express transit energy efficiency in terms of BTUs per passenger-mile. The BTU is the English system unit of energy, and it's equal to 1055 joules. On pure conversion, there are 3413 BTUs in a kw/h. To turn BTUs/mile into miles per gallon, you divide into 125,000, the number of BTUs you get from burning a gallon of gas.
...
The DoE figures describe the average car as using 5500 BTUs/mile (23mpg) or 3,500 BTUs/passenger mile with an average load of 1.57 passengers. This is a "fuel to wheels" number based on burning the gasoline.

<p>Putting the car at 3,500 I was disturbed to learn that city diesel buses and electric trolley buses are both mildly worse than the car in energy efficiency. Light rail systems are also slightly worse, on average, though it varies a lot from city to city. Commuter rail and subway (heavy rail) trains tend to be a bit better, but not a lot better. (Non-hybrid cars are also better at long haul than they are short haul.)<br />
</blockquote></p>

<p>Templeton is basically right, I have seen this data before, and we make basically the same argument in <a href="http://nexus.umn.edu/Books/TTE.html">The Transportation Experience</a> (Chapter 19). (A car with 4 passengers would be much much better, since the metal per person in a car is much less than on transit, of course cars generally have less than 4 persons most of the time).</p>

	         <title>Traffic Congestion and Infant Health: Evidence from E-ZPass</title>
         <description><![CDATA[<p><a href="http://papers.nber.org/papers/w15413">Traffic Congestion and Infant Health: Evidence from E-ZPass</a> by Janet Currie and Reed Walker</p>

<p> <br />
<blockquote><br />
This paper provides evidence of the significant negative health externalities of traffic congestion. We exploit the introduction of electronic toll collection, or E-ZPass, which greatly reduced traffic congestion and emissions from motor vehicles in the vicinity of highway toll plazas. Specifically, we compare infants born to mothers living near toll plazas to infants born to mothers living near busy roadways but away from toll plazas with the idea that mothers living away from toll plazas did not experience significant reductions in local traffic congestion. We also examine differences in the health of infants born to the same mother, but who differ in terms of whether or not they were "exposed" to E-ZPass. We find that reductions in traffic congestion generated by E-ZPass reduced the incidence of prematurity and low birth weight among mothers within 2km of a toll plaza by 10.8% and 11.8% respectively. Estimates from mother fixed effects models are very similar. There were no immediate changes in the characteristics of mothers or in housing prices in the vicinity of toll plazas that could explain these changes, and the results are robust to many changes in specification. The results suggest that traffic congestion is a significant contributor to poor health in affected infants. Estimates of the costs of traffic congestion should account for these important health externalities.</blockquote><br />

	         <title>How to Get More Bicyclists on the Road</title>
         <description><![CDATA[<p>From SciAm: <a href="http://www.scientificamerican.com/article.cfm?id=getting-more-bicyclists-on-the-road">How to Get More Bicyclists on the Road</a><br />
<blockquote>To boost urban bicycling, figure out what women want ....</p>

<p>In the U.S., men's cycling trips surpass women's by at least 2:1. This ratio stands in marked contrast to cycling in European countries, where urban biking is a way of life and draws about as many women as men--sometimes more. In the Netherlands, where 27 percent of all trips are made by bike, 55 percent of all riders are women. In Germany 12 percent of all trips are on bikes, 49 percent of which are made by women.</blockquote></p>]]></description>
