Travel on all roads and streets changed by 0.3% (0.9 billion vehicle miles) for October 2012 as compared with October 2011. The 12-month moving average of miles driven increased only 0.51% from October a year ago (PDF report). And the civilian population-adjusted data (age 16-and-over) has set another post-financial crisis low.
Here is a chart that illustrates this data series from its inception in 1970. I'm plotting the "Moving 12-Month Total on ALL Roads," as the DOT terms it. See Figure 1 in the PDF report, which charts the data from 1987. My start date is 1971 because I'm incorporating all the available data from the DOT spreadsheets.
The rolling 12-month miles driven contracted from its all-time high for 39 months during the stagflation of the late 1970s to early 1980s, a double-dip recession era. The most recent dip has lasted for 55 months and counting — a new record, but the trough to date was in November 2011, 48 months from the all-time high.
