Personal Velocity

I came across the article Living at Jet Speed the other day (reprinted from Newsweek). It referred to personal velocity - a measure of how fast you travel on average every hour of the year. Take your total travel distance (flying, car, train, bus, etc) and divide by 8760 (the number of hours in a year).

The author, Joshua Ramo Cooper, had a personal velocity in 2005 of 45.8 miles per hour. I came across a few other references - William Arruda 28.3 miles per hour, and a few mentions on Flyertalk in the annual travel summaries some people post.

2005 was a big travel year for me and my personal velocity was 42.8 miles per hour, or faster than the speed limit in the built up parts of my city.
