Info

Most travel (78%) recorded in the travel periodsection was for trips over 100 miles in length.Trips of 11 to 20 miles in length resulted inmore VMT than trips of any other distance.These trips made up 22% of the total VMT inthe travel day (adjusted) section.TABLE 2.10ESTIMATES OF TOTAL TRAVELTOTAL VEHICLE MILES OF TRAVEL BY DATA SOURCE AND TRIP LENGTH1995 NPTS(MILLIONS)Travel Day AdjustedSectionTOTAL 1,976,879(91,489)0 to 5 miles 314,779(739)Travel PeriodSection385,997476 to 10 miles 315,352(852)11 to 20 miles 437,805(1,378)21 to 30 miles 254,363(1,977)31 to 50 miles 255,536(3,366)51 to 100 miles 167,687(22,264)Over 100 miles 231,357(60,914)978813,81414,22263,955302,980Note:• All tables reporting totals could include some unreported characteristics.• The numbers in parentheses are the travel estimated for overlap trips, which are excluded from the travel day estimates toavoid double-counting. Travel day estimates without overlap trips are referred to as the “Travel Day Section Adjusted.”Vehicle miles in commercial driving cannot be shown on this table because individual trip lengths were not collected forcommercial driving data.• The travel day section includes linking trips that are part of a travel period trip. For example, an airplane trip fromWashington, DC, to Oak Ridge, TN, taken on the travel day, plus ground transportation to and from the airports areconsidered one trip in the travel period section. However, due to definitional differences, these trips are three separate tripsrecorded in the travel day section. All of the three trips are referred to as “overlap trips.” Consequently, there are overlaptrips recorded in the travel day section which, individually, are less than 75 miles long, but collectively are over 75 miles longand, therefore, included in the travel period section as well as in the travel day section. These miles are then adjusted out ofthe travel day estimates to avoid double counting.2-18NATIONWIDE PERSONAL TRANSPORTATION SURVEY
