It is simple to understand the idea: the time we spend stuck in traffic takes an economic toll (lost wages, lost sales, etc). Those expenses, in turn, are part of a broader cost to society that we all bear as a result of gridlock (lost productivity, air pollution and its associated medical costs, etc). A recent study by AAA, however, puts forward a, perhaps, more startling idea: that the societal cost of auto accidents is far higher than that of mere congestion.
As outlined in a recent article from The Oregonian, the study put the overall “cost to society” of traffic congestion at $958 million per year for the Portland-Beaverton-Vancouver metro area. An eye-popping figure, to be sure. Using the same data, however, it concluded that “the annual societal cost of traffic crashes… is $2.74 billion.” The analysis was based on 2009 data (the newspaper article, accessed through the link below, includes, in turn, a link to the original report in pdf form).
The article goes on to note that these Oregon car crash figures are roughly in line with national averages. On a national basis the spread between the true cost of vehicle crashes versus the true cost of congestion is $300 billion versus $97.7 billion, making the ratio roughly 3-to-1 at both the state and the national level.
