American Driving Survey: Methodology and Year One Results, May 2013 – May 2014

Le résumé fourni par la source

This report documents the methodology of the American Driving Survey (ADS) as well as the results of the first full year of data collection, which occurred between May 21, 2013 and May 31, 2014. Interviews were conducted with 3,319 drivers sampled from among 4,287 households that were initially contacted and screened. The first year data show that all drivers 16 and older drive, on average, 29.2 miles per day or 10,658 miles a year. Men reported driving more miles than women; Caucasians reported driving more miles than respondents of other races; Hispanic respondents reported driving the least. Teenagers and drivers ages 75+ also drive significantly fewer miles on average. About one-third of all drivers did not drive at all on the day about which they were interviewed. About 50% of all miles driven are in a car, and another 40% in a sports utility vehicle (SUV) or pickup truck. People drive, on average, more on weekdays and less on weekends. There is a significant mileage gap between rural and urban drivers, but the gap is smaller on the weekends than on weekdays. People drive, on average, less during the winter months and more during the summer months. To investigate the extent to which data from the ADS was similar to or different from other data from other well-accepted sources, data from the ADS was compared to data from the Federal Highway Administration’s 2009 National Household Travel Survey (NHTS).
