Chart of the Day: Trains, Buses and Taxis… A rough guide to estimate your travel time from city center to 40 busiest American airports

Numbers guru Nate Silver & his team over at FiveThirtyEight have done an interesting travel time analysis that deserves a gold medal.. Below is the fruit of their labor and don’t forget to read the accompanying analysis here. One thing is clear from reading this analysis – our transportation network is really messed up and there is a lot to be desired in terms of improved multimodal connectivity (involving public transportation).

An insight into the American commute — Which Cities Sleep in, and Which Get to Work Early

April 22, 2014 at 6:29 pm

My favorite numbers guy, Nate Silver at FiveThirtyEight has poured over the census data and published an intriguing article that shows how the workforce in US cities begin its work day. I’ll share Nate’s findings through the graphs he published but I highly recommend that you read the full article over at his site . This insightful analysis will be definitely useful for transportation systems operators and managers.

Here are a few data nuggets from this analysis:

  • New Yorkers are pretty relaxed and get to catch a few more winks  than many in the country. The median worker in the New York metropolitan area begins her workday at 8:24 a.m. 
  • A quarter of the workforce in Atlantic City doesn’t begin its workday until 11:26 a.m. or after (understandably because the AC workforce is dependent on a recreational economy).
  • The metro area with the earliest workday is Hinesville, Ga. The median worker there arrives at work at 7:01 a.m.

Americans Driving Less- Temporary, or Permanent? – Statistics whiz Nate Silver wonders if we are near the end of car culture

May 6, 2009 at 7:25 pm

Nate Silver, the baseball stats guy turned election predictor, takes a look at the statistics showing that Americans are driving less.

This is surely one of the signs of the apocalypse: Americans aren’t driving as much as they used to.

Graphic: Bryan Christie Design/ We are driving a lot less in this country, even less than one would have expected in a bad economy with fluctuating gas prices. The graph above charts 1) actual miles driven per capita in America during each January for the last thirty years and 2) how many miles per capita we could have been expected to drive based on my model, which accounts for changes in population, gas prices, unemployment rates, and other factors. The downward trend last year was stark. Indeed, Americans have rarely cut back on their driving so consistently for so long.

In January, according to statistics compiled by the Federal Highway Administration, Americans drove a collective 222 billion miles. That’s a lot of time spent behind the wheel — enough to make roughly eight hundred round-trips to Mars. It translates to about 727 miles traveled for every man, woman, and child in the country. But that figure was down about 4 percent from January 2008, when Americans averaged 757 miles of car travel per person. And this was no aberration: January 2009 was the fifteenth consecutive month in which the average American drove less than he had a year earlier.

The one thing that has sometimes caused Americans to put on the brakes is higher gas prices. Although driving is a relatively inelastic activity — a doubling of gas prices reduces miles traveled by only a small fraction — it has nevertheless been somewhat sensitive to changes in fuel costs. Vehicle miles traveled fell between 1981 and 1982, for instance, when the price of gas was the equivalent of three dollars in today’s prices, and between 1990 and 1991, when the Persian Gulf war triggered a temporary spike in the price at the pump.

Gas prices, of course, were exceedingly high last summer, peaking at $4.06 a gallon in July 2008; it isn’t surprising that Americans were driving less then. But prices have since fallen by more than half, and Americans have yet to pick up the pace on the roads.

How much of it is just a result of the bad economy? The unemployment rate has soared significantly since last summer; perhaps the only good thing about losing your job is that you no longer have to endure the drive to work.

Thus, the continued decrease in driving today reflects, in part, a delayed reaction to hundred-dollar-a-barrel oil. Maybe our commuter finally did get fed up and move his family to the city, but it took him until now to do so. The real test will come as the summer unfolds and Americans have had time to get “used to” lower gas prices.

Still, there is some evidence that more Americans are at least entertaining the idea of leading a more car-free existence. Between October 2004, when gas prices first hit two dollars a gallon, and December 2008, when they fell below this threshold, three cities with among the largest declines in housing prices were Las Vegas (-37 percent), Detroit (-34 percent), and Phoenix (-15 percent), each highly car-dependent cities. Conversely, the two markets with the largest gains in housing prices were Portland, Oregon (+19 percent), and Seattle (+18 percent), communities that are more friendly to alternate modes of transportation.
