2002–2015 Texas Regional Travel Surveys

From 2002–2015, multiple household travel surveys were conducted across Texas in Abilene, Austin, Bryan-College Station, Corpus Christi, El Paso, Houston/Galveston, Laredo, Midland/Odessa, Rio Grande Valley, San Angelo, San Antonio, Texarkana, Tyler/Longview, and Wichita Falls.

Data Collection Agency

In coordination with the Texas Transportation Institute, the Texas Department of Transportation conducted the surveys.

Methodology

The travel surveys incorporated a global positioning system (GPS), technology-based travel diary component.

Drive Cycle Processing and Filtering

NREL has developed a GPS data filtration routine to filter erroneous data points in individual drive cycles sourced from GPS devices mounted in vehicles. Second-by-second drive cycle data collected from GPS-instrumented vehicles during these surveys have passed through NREL's drive cycle processing and filtering routines.

Survey Records

Survey records include 5,825 households.
