We just updated the page where we are tracking the statewide traffic volumes. This month's update is rather amazing, showing that the traffic was nearly 5 percent less last month than it was in 2007, 2006 and in 2005.
We show all three of those years so you can get a sense of the trend, especially since typically Americans drive more each year, not less. We would expect a 3 percent increase in a typical year. In the first five months of 2008, we were seeing a roughly 2 percent drop in volume. But in June, driving tanked. Amazing.
But notice the chart above that shows the average monthly gas prices along with the drop in traffic volumes? The price of gas goes up, the drop in traffic volumes fall.
