TxDOT obtains information on travel behavior from travel surveys and uses it to develop trip generation and trip attraction rates from each urban area. A typical travel survey in Texas contains a household survey, an establishment survey and external data analysis using passive data. Support is available for MPO or transit agency conducted surveys, i.e. on-board public transit surveys. In some nonattainment or near nonattainment areas, an air quality survey may be conducted.

TxDOT’s Travel Survey Program supplements internal efforts using InfoGroup data and National Household Travel Survey (NHTS) data.
