Vehicle Miles per Year USA for Bicycles
Does anybody know what the generally accepted numbers
are for total yearly bicycle usage in the USA? Does less than 1 billion vehicle miles sound right? The most rigorous citation I can find on the net is: http://www.bts.gov/omnibus/targeted/...hts/index.html This survey found that 91M bicycle trips were taken from May 1 to Sep 1 2002, average length 3.9 miles. This would imply 400M vehicle miles for the 4 summer months. One would think this implies less than 1B vehicle miles per year. Any other sources? |

The CPSC study (http://www.cpsc.gov/cpscpub/pubs/344.pdf) from '93 found that: "Survey results confirm the popularity of bicycle riding in the U.S. There are an estimated 66.9 million bicyclists who reportedly spend about 15 billion hours riding bicycles in a year." At a conservative average speed of 8 mph that would be about 120 billion miles. Failure Analysis Associates estimated the fatality risk of cycling at 0.26 per million hours of riding. Since there are about 800 fatalities per year this implies a little over 3 billion hours of riding per year (24 billion miles at 8 mph). |

Under one billion sounds intuitively low. There are about 300,000,000
Americans. Say 10% do some bike riding, and average 35 miles a year each, and you come up with a little over a billion. Or if just one of a hundred Americans averages 350 miles a year, you reach a billion even if the other 99% do no riding at all. We're not very bike oriented in this country, but I think we do at least that well. "Peter" wrote in message news:lSJFb.625074$Tr4.1617894@attbi_s03...
