ESTIMATES OF TOTAL TRAVELFigure 2.1 and Table 2.2 show the distributionsof person miles of travel by trip purpose asreported through the travel day and travelperiod sections of the questionnaire. Almost80% of personal travel was reported in thetravel day (adjusted) section, which implies thatmost travel was comprised of trips less than 75miles long. Trips of 75 miles or more (one way)– that is, the travel period section – wereprimarily social/recreational trips. Although lessthan 13% of all person miles for going to workwere listed in the travel period section, over halfFIGURE 2.1of the person miles for work-related businesswere reported in the travel period section.The returning home category, added in the1995 NPTS to assist in coding to-from trips,designates the purpose of returning to therespondent’s residence. Returning homerepresents about one-third of all travel day trippurposes. Table 2.3, which is comparable toTable 2.2, uses 1990 trip purposes.DISTRIBUTION OF PERSON MILES OF TRAVEL BY DATA SOURCE AND TRIP PURPOSE1995 NPTSEarning a Living600,777 199,322School/Church102,094 16,276Family/Personal Business774,332 145,446Social/Recreational657,825 499,239Other11,332 8,834Returning Home1,040,1700 10 20 30 40 50 60 70 80 90 100Miles (in millions) and Percentage of Total PMTTravel Day Section Adj.Travel Period Section2-6NATIONWIDE PERSONAL TRANSPORTATION SURVEY
