Data Extraction Tool and Visualization Prototypes
Data Extraction Tool (DET)
This data extraction tool allows users to obtain data from 1995, 2001, or 2009 National Household Travel Surveys (NHTS) to examine total travel (i.e., person trips, person miles traveled, vehicle trips, and vehicle miles traveled). This tool also allows users to extract data from all three surveys for trends analysis. The user can select one or more elements using selection criteria to generate a customized data set. This customized data set can be downloaded in CVS format for additional analyses.
For the add-ons, the user can extract data from a specific add-on. Note: the samples sizes used to generate area-specific travel can be extremely small. Users are advised to use these data with caution.
The customized data set will include the user-selected criteria (e.g., household income), total travel
(i.e., person trips, person miles traveled, vehicle trips, and vehicle miles
traveled), and the corresponding sample size used to estimate total travel.

Data Visualization Prototypes
The Data Visualization Tool provides several approaches to viewing the most commonly-accessed data from NHTS, namely trip rates, trip purposes and mode of travel. The Visualization Tool presents NHTS data in the format of a map, pie-bubbles and a dashboard configuration. This tool provides access to the 1995, 2001 and 2009 surveys and facilitates easy comparison of travel parameters over time.

NOTE: A screen resolution of 1680 x 1050 (or higher) is recommended for using these prototypes.
