Traffic


I just finished my second book of 2010 - Traffic: Why We Drive the Way We Do (And What It Says About Us) by Tom Vanderbilt. Aside from the over-punctuated and heavily-worded title, it was an interesting glimpse into the genesis of traffic jams, the danger involved with driving a car, and what we can all do about it.

What makes all of this so perplexing is that cities have employed traffic specialists since the 1800s (to manage all the horses, not even to speak of their poo), and no one can nail down anything close to an accurate answer to explain much of our traffic woes.

Traffic engineers have gone to miraculous lengths to make safer, more forgiving roads only to learn later that these roads encourage drivers to try even riskier high-speed maneuvers. Some more dangerous roads actually operate more safely because drivers concentrate on driving safely. Vanderbilt interviews traffic experts (more than you would have ever thought existed) and even speaks to "one of the leading experts" in queue formation.

But there are answers.

To put it simply, the easiest way to alleviate traffic is for you to get off of the road and get out of my way so I can get to work on time.* Of course, it doesn't work, because what's good for society (or for gridlock) certainly isn't good for the individuals most affected. It's why listening to the traffic report works best when you're the only one listening to it. When the radioman says that an alternate route in Chicago is faster, it's not surprising that 30,000 people sprint to clog up the alternate route.

* From the Onion: 98% of People Favor Public Transportation for Others.

Similar is the concept of night driving. One of Vanderbilt's most ostentatious claims is that in order for night driving to be as safe as day driving, we'd all have to move at 20 mph. Of course, if you move along at that kind of a speed (or lack thereof) on a highway, you are in significantly more danger because not everyone is going to heed that advice.

Smaller, lighter cars are safer - but only if everyone drives one. If you're the only one, then your car is significantly more dangerous, at least to yourself.

This book made me think, and mostly it made me think about this: I wonder what it would take to become an expert in queue formation.
