I used the NHTS on-line table generator to run these numbers for you. The trip purpose (1990 NPTS definition of TO AND FROM work) was used and applied to the 2001 NHTS. This is a different definition from decennial Census journey-TO-work. So, I also ran the travel time, with the 2001 results nationwide being 23.5 minutes. From decennial census, we get 25.5 minutes for journey-to-work in 2000. You can use the NHTS on-line table generator to examine distributions of trip lengths and trip durations by trip purpose. http://nhts.ornl.gov/2001/index.shtml Elaine Murakami, FHWA Office of Planning; 206-220-4460 2001 NHTS Average Person Trip Length (miles, Travel Day) Where worker = '1' (Continued) TD Person Trip Length Sample Size Mean 1990 NPTS trip purpose 35,658 12.21 To/From Work Work-Related Business 6,959 30.24 Shopping 25,449 7.29 Other Family/Personal Business 32,559 7.46 School/Church 6,600 7.80 Medical/Dentral 2,338 11.04 Vacation 738 45.12 Visit Friends/Relatives 7,942 18.15 Other Social/Recreational 22,250 9.35 Other 746 19.47 N/A 460 89.97 Refused 9 6.14 All 141,708 11.25 Average Person Trip Duration (minutes, Travel Day) Where worker = '1' (Continued) TD Person Trip Duration Sample Size Mean 1990 NPTS trip purpose 35,638 23.50 To/From Work Work-Related Business 6,951 33.46 Shopping 25,337 15.16 Other Family/Personal Business 32,337 15.87 School/Church 6,612 17.10 Medical/Dentral 2,342 21.29 Vacation 736 61.88 Visit Friends/Relatives 7,867 27.11 Other Social/Recreational 22,127 20.84 Other 747 34.76 N/A 479 49.22 Refused 9 14.61 All 141,182 20.58 -----Original Message----- From: Estersohn Dan [mailto:Dan.Estersohn@arbitron.com] Sent: Mon 2/9/2004 5:06 PM To: ctpp-news(a)chrispy.net Cc: Subject: [CTPP] Average Miles to Work We are working on a project that requires a U.S.-level average miles to work number.
