Is Traffic Congestion Growing Three Times As Fast As Economy? 187

cartechboy writes "Math watch time: For many traffic analysts, INRIX is considered the gold-standard. This week the company says traffic congestion surged in 2013 and grew over three times as fast as the American economy. The bad news: If true, this reverses two consecutive years of traffic declines with a six percent increase in 2013. (GDP, by comparison, grew 1.9 percent last year.) The analysts then theorize links between economic growth and traffic congestion, which makes sense on the surface. (As the economy improves, more jobs are created, so more commuters on the roads) But INRIX's theory creates as many questions as it answers. For example, the U.S. GDP has been steadily growing since 2009. So why did congestion decline in 2011 and 2012?"

    So why did congestion decline in 2011 and 2012?

    The false equivalence between GDP and labor (and therefore commuting.)

    We're shedding workers. The labor participation rate is declining. GDP, like inflation, the unemployment rate, cost-of-living, etc. are political fictions derived from politically derived formulae.

      For the most part, numbers like GDP, inflation and unemployment are useful to social scientists and policymakers who know their limitations and not necessarily super useful to the public. The methodologies aren't designed to be misleading, but they are designed to capture certain details that are useful and exclude certain things that the public might thing should be included for "common sense" reasons.

The Bureau of Labor Statistics calls or visit a randomly selected sample of Americans, ask them if they are employed, and if they are not, are they looking for a job. While they ask some other questions, those are the basic ones used to determine the widely-publicized unemployment rate. This is not a complicated statistical formula here, subject to all sorts of evil manipulation.

      I know this is going sound like an attack, but congestion is due to a number of factors. In my area the congestion has increased rapidly. One factor I have seen is that there are once again many trucks and SUVs on the road. In 2010, with gas prices usually around $4, I saw a decrease in the number of these large vehicles. Now gas is back down to around 3.50, which is what is was back in 2007. Cheaper gas not only means people can afford to drive more, it means they can afford less efficient cars.

Besides raising the cost of housing, laws such as minimum parking requirements and prohibitions against accessory dwelling units reduce property rights and restrict economic mobility, all in the name of keeping the riffraff (i.e. the poor and minorities) out.

    But INRIX's theory creates as many questions as it answers. For example, the U.S. GDP has been steadily growing since 2009. So why did congestion decline in 2011 and 2012?"

    I know in my area, transit has become decidedly less desirable in the past year or so as it's become more crowded. A few years ago I could almost always get a seat and commute in relative comfort. Now the trains are so full that some days it skips my stop (or even if it stops to let someone off, there's not enough room to squeeze on). Biking is an option for me, so I've been biking regularly, but if that wasn't an option, I'd probably drive rather than take an unreliable train that's uncomfortably full. Equipment purchases are large capital expenses that can take years or evena decade to plan, fund, and complete, so public transit lags demand.

    According to INRIX, traffic in the U.S. reversed two consecutive years of declines with a six percent increase in 2013. The country's GDP, by comparison, grew 1.9 percent last year. INRIX suggests that continued economic growth will result in more traffic congestion, longer commutes, and more productivity losses.

    INRIX is getting their conclusion from one data point: last year. Even though previous years do not support their conclusion, multiple data points. As a result, their conclusion that traffic increases at 3 times GDP growth is not convincing. They need to put a lot more effort into this study. Even the article author pointed that out,

    Bottom line: roadways are complex ecosystems, and congestion results from jobs, commuters, road work, mass transit, and countless other factors. While it's encouraging to see traffic jams as symbolic of economic growth, that's not an accurate or complete picture.

    In a complex environment like this, data needs a control point and a link from cause to effect. All I see here is a very loose correlation in one year of data. Hence, this is FUD.

  • The increase in congestion due to increased economic activity and reduced unemployment isn't just a factor of more people on the road. When the economy improves, people get offered better piles of money to take jobs farther from their homes. People drive farther in a good economy. Then add in all the ancillary travel from increased economic prosperity, eating out more, buying more stuff, going more fun places.

    If you look at places like San Francisco and the way wealth is pooling there, it's easy to understand why traffic congestion is growing faster than the economy.

    If you put a bunch of rich-ass people together in one highly-concentrated place, even if all of them are working from home or taking Google busses to work, they're going to need services. Grocery stores, plumbers, babysitters, teachers, restaurant workers, you name it. Many of those sorts of jobs are not ones which are compatible with telecommuting--if my garbage man starts working from home, I'm going to be pissed!--and most of them are not of an income level which would allow a comfortable residence within the city where the job is. If you're making $30,000 a year as a teacher, spending $2,000 a month on a 400 sq ft studio apartment so you can walk or bike to work doesn't leave much left over for food and the like.

    So inevitably, thousands upon thousands of workers need to commute various distances to keep their jobs and live in some level of comfort.

    I realize that SF, as a peninsula, is a fairly unique scenario: it provides a high-value destination with severely constrained access points. Maybe not the actual logical conclusion of all similar circumstances, but a useful indicator of how things might play out in areas where money is aggregated into smaller and smaller groups who then take over relatively small and very desirable locations.

That mostly has to do with the fact that the area has one of the worst transit systems I have seen in my life.

Mind you, this is Germany, where there are better and more roads per capita, far less speed limits and people actually know how to drive. 4.7 fucking billion man hours per year. Let that sink in for a minute. And that's like 80% of the monetary income generating population wasting that sort of time (I won't say working population, for obvious reasons).

    With that time wasted, we could send every person in the workincome population on a paid 3 week vacation each year and still have money to spare.

    Cars are an anomally, only around today for mostly historical reasons, with no sensible reason at all. Sort of like the PC keyboard or MS Windows. Only with far more negative impact on overall quality of living and the environment.

    Most populations and societies would be better of if we banned private cars alltogether and switched to e-bikes and public transport entirely. With taxis and cargo taxis for the special occasions. Would be cheaper for all, faster for all, better for the environment and we'd all be happier for it. I'd bet money on that.

    If I were a billionaire I'd pay some bankrupt German cities to ban cars alltogether and then heavyly invest in them and then sit back and watch the local economy and quality of living skyrocket.
