Grid Bits: Englewood railroad yard; Metra asks passengers to watch conductors

In Grid Bits for Tuesday, September 20, 2011, Metra wants customers to report on customers and conductors who miss fares; Evanston wants to build an infill Yellow Line station; additional automobile crash analysis; Chicago police are looking for a hit-and-run driver; a railroad plans to expand by buying and demolishing homes in Englewood. There are 6 stories in this post.

Uninsured drivers and other tales

[flickr]photo:625959597[/flickr]

Yesterday I posted this statement about automobile crashes on my Facebook wall:

‎36.9% of all automobile crashes (including the ones involving pedestrians and bicyclists) in 2010 were labeled “hit and run” by IDOT.

I pulled this information from the crash data I’ll be analyzing and visualizing with three other people.

The first comment I received asked if that number was related to the number of uninsured motorists in Chicago. I found a report published by the Insurance Research Council (IRC; funded by property casualty insurance companies) that estimated, for 2009, 15% of drivers in Illinois do not have insurance. The estimates were “based on the ratio of uninsured motorist insurance claim frequency to bodily injury claim frequency.” I don’t know if this is a good, or the best measurement technique, but it’s one way that we can compare annual data. It seems this method will not include crashes where neither driver has insurance (driver or medical), or when no claim is made against the uninsured driver.

Then today I was at MicroCenter in Logan Square shopping for a computer hard drive. Someone else was standing next to me looking at some of the same products. He got a phone call. It went something like this. (Note: I did not hear anything the caller said – I’m making it up based on his responses.)

  • Caller: What are you doing?
  • Man: Shopping for hard drives.
  • Caller: How’d you get there?
  • Man: I’m borrowing this person’s car.
  • Caller: Let’s go somewhere.
  • Man: No, I don’t care, I’m not taking you on a joy ride. I haven’t had a license for three years. If I get pulled over, I’m going to jail.

What the heck does one do in this situation? Do you call the police and report that a driving crime is about to happen?

Simply because he has no license doesn’t make him a bad driver, but his tone and his message to the caller indicated, to me, that his license to drive was taken from him. But that was a little deterrent. He calculated his risk and concluded it was low enough to borrow someone’s car and drive to the store to buy a hard drive, but that driving any further (taking the caller on a joy ride) was too risky. There’s probably some correlation that the longer distance one drives, or the more time one drives, the more likely they will be pulled over. But for there to be that correlation, police officers would have to be 1) randomly distributed across the region where this person is driving, and 2) paying attention to driver infractions.

As long as the man avoids making errors and ensures the borrowed car meets legal requirements to drive (lights, registration, etc…), then he will avoid being pulled over. Since the IRC estimates that 15% of drivers in Illinois have no insurance, it may be prudent for the police to randomly pull over a certain percentage of drivers each year simply to check for valid insurance. When there’s a crash with an uninsured driver, that infraction of driving without insurance is just as important to public safety as the action that caused the crash. Not every insured driver carries uninsured motorist insurance to protect themselves, monetarily, from this situation.

I searched Flickr for “uninsured driver” and this was one of the photos that appeared. The driver of the white car hit the dark car in the foreground. The photo was posted by one of the people in the dark car and says that the driver of the white car did not have driving insurance. Photo by vikisuzan in Kent, Washington. 

Highlights from MBAC, and room for improvement

Alderman Laurino, 39th Ward, talks about her proposed ordinance that would ban texting and other tasks while bicycling. See “More topics” below. 

These are the highlights from the Mayor’s Bicycle Advisory Council (MBAC) meeting last Wednesday, September 13, 2011. The next meeting is Wednesday, December 14, 2011, at City Hall, 121 N LaSalle Street.

New protected bike lanes

These two protected bike lanes (PBL) will be installed in 2011. These were announced by Chicago Bicycle Program Bikeways Engineer David Gleason and Bikeways Planner Mike Amsden. Continue reading Highlights from MBAC, and room for improvement

“The subway is the place where denizens of the great metropolis are now forced to face each other. The wealthy, and the poor rub more than elbows here. Often the pot in which we are all supposed to be melting cracks and boils over.” -New York City-based photographer, Dave Beckerman.

How hydrogen cars work

I wrote this summary to further inform readers who have questions about the Hyundai Tucson Fuel Cell Electric Vehicle and the article John wrote about its visit to The Drake hotel in Chicago.

Under the hood of Hyundai’s Tucson Fuel Cell Electric Vehicle. 

What’s in the car?

Inside the car are fuel cells, devices that convert the chemical energy of hydrogen (or another chemical) to electricity. Hydrogen is used because of its simplicity: “An atom of hydrogen consists of a single electron and a single proton.” With the hydrogen,

The fuel cell generates electricity by stripping the electrons from the protons and using the electrons to create a pure stream of electricity. The ionized hydrogen atoms then combine with oxygen to form water. The other byproduct of this process is heat, so this water generally takes the form of steam. (HowStuffWorks)

Also inside the car are hydrogen tanks; the Hyundai Tucscon has one tank holding 12.3 pounds of hydrogen. With the electricity from the fuel cells, a 134 horsepower motor drives the car.

Where does the hydrogen come from?

Hydrogen is extracted from hydrocarbons, mainly natural gas, a fossil fuel. In 2010, the United States produced 89.4% of the natural gas it consumed, importing the remainder from Canada, Trinidad, Egypt, Qatar, and Nigeria (top 5 by imported volume).

How is the hydrogen obtained?

There are two methods, and most hydrogen in the United States (95%) is obtained with steam-methane reforming. When natural gas is used to extract hydrogen*, the methane in natural gas reacts with steam  at a temperature of 1,292°F (700°C) to 1,832°F (1,000°C), in the presence of a nickel-based catalyst, and produces hydrogen, carbon monoxide, and a relatively small amount of carbon dioxide.

In the second process, called water-gas shift reaction, “the carbon monoxide and steam are reacted using a catalyst to produce carbon dioxide and more hydrogen” (U.S. DOE). In the final process, called pressure-swing adsorption, the carbon monoxide and carbon dioxide are removed, leaving the hydrogen.

*Alternatives to natural gas as a source for hydrogen include methanol, ethanol, propane, or gasoline (U.S. DOE).

Sources are linked and comprise HowStuffWorks, United States Energy Information Administration (EIA), and the United States Department of Energy (DOE), Haldor Topsoe (a catalyst research company), and Car & Driver. 

Is there such a thing as a “green” car?

When Zoe Stathopoulos, an ad exec from Ruder Finn, contacted Steven and me to invite us to the Chicago stop of Hyundai’s Drive 4 Hope event promoting the Tucson Fuel Cell Electric Vehicle (FCEV), a hydrogen-powered car, it raised our eyebrows.

“I think this is right up your alley given your interest in sustainable transportation in Chicago,” she wrote. “As those who are interested in green/clean energy and the environment know, nothing in the automotive industry holds more promise for the health of the planet than fuel cell technology.” Continue reading Is there such a thing as a “green” car?
