How do you get there from here?

I have been trying to look up statistics on safety of walking vs. driving- so far I haven’t found much useful information- but I did find this terrific report put out by the U.S. Department of Transportation, Bureau of Transportation Statistics: the 2001 National Household Travel Survey (NHTS).
The NHTS focused on travel within 50 miles of the home and so took into account walking and biking. Highlights show that 45 percent of all daily trips were for family and personal reasons (doctor, shopping, errands), 27 percent were for social, recreational purposes and 15 percent were for work. The mode of transportation used to “commute to work in the past week” was 91.2 percent personal vehicle, 4.9 percent transit, 2.8 percent walking, 1.1 percent other.
The distribution of daily trips was spread rather evenly throughout the week with Friday getting the highest percentage at 15.6 and Sunday the lowest at 12.9. The census shows that daily travel totaled 4 trillion miles in 2001, or an average of 14,500 miles per person per year. The average adult spends 55 minutes behind the wheel traveling 29 miles daily.
A statistic I found sad, but probably not representative for Flagstaff or other physical active communities, was that nationally the mean number of personal vehicles per household was 1.90, while the mean number of adult-sized bicycles per household was 0.86 (8 percent of the households have no vehicle).
What do I get from this? We have a lot of room for improvement when it comes to alternative transportation! I wonder if anything has changed since 2001...
