National Household Travel Survey - 1990

The Nationwide Personal Transportation Survey compiles national data on the nature and characteristics of personal travel. It addresses a broad range of travel in the United States, providing data on all personal trips for all purposes and all modes of transportation. When the 1990 data is used in conjunction with previous NPTS data, it is possible to track, over time, both personal travel and the characteristics related to that travel for the entire nation. NPTS data may be used to describe current travel patterns and, given projections of demographic change, can provide a valuable tool to forecast future travel demand. <br><br>The 1990 NPTS closely follows the data collection design used for the previous surveys. Information from a national household sample was collected about all trips taken during a designated 24-hour period (travel day). Additional details were collected for trips of 75 miles or further (one-way) that were taken during the preceding 14-day period (travel period) including the 24-hour travel day. The information collected for each trip includes the purpose, mode, trip length, day-of-week, time-of day, vehicle used, and vehicle occupancy. <br>The 1990 Nationwide Personal Transportation Study is an earlier iteration of the currently ongoing National Household Travel Survey. The name is different but it is still connected.<br>
