TxDOT conducts regional surveys every 10 years to identify travel patterns in urban areas across the state. The results help TxDOT and local planning organizations make cost-effective decisions about transportation projects. Types of surveys include:
The household survey asks randomly-selected residents to record where, when and how they travel during a single day. TxDOT takes care to ensure that a wide range of people are surveyed and that results can be expanded to characterize all residents’ travel.
The workplace survey helps determine the amount of travel generated by local businesses and organizations. Survey methods include on-site vehicle or pedestrian counts as well as interviews with employees, visitors and delivery drivers.
- Commercial Vehicle
The commercial vehicle survey asks local businesses and organizations to record driver trip information for a single day. These results help TxDOT estimate commercial vehicle traffic and the types of cargo being transported.
The external survey collects data on vehicles entering, exiting, and traveling throughout the area using cellular, Bluetooth, GPS and other methods.
