The Travel Survey Program (TSP) provides specialized technical support and expertise in travel surveys and data analyses that enables TxDOT and its MPO partners to meet their federally mandated requirements in transportation planning. The program allows for independent QA/QC, consistency in data collection, and ensures that survey support and recommendations are tailored to TxDOT and MPO needs. As part of the program, travel surveys are conducted in each of the states 23 MPOs about every 10 years on a re-occurring basis. In order to accomplish this, the states 23 MPOs are consolidated into 14 travel survey regions.
Three types of travel surveys are conducted in urban areas in Texas as part of TxDOT’s TSP. These include Household Travel and Activity Surveys, Workplace and Special Generator Travel Surveys, and Commercial Vehicle Travel Surveys. External Travel Studies are also performed by TTI in concert with these efforts. Together, this coordinated data collection and analysis work generates the information required to assess local transportation uses and needs. Planners and modelers use the data to simulate travel on a typical day and to develop future forecasts. This allows decision makers to evaluate the impact of various transportation improvement scenarios.
As part of the program, TTI researchers prepare project scopes and materials, test and troubleshoot web and smartphone survey applications, monitor the status of project tasks and data collection, and provide independent assessments of data and deliverables on a real-time basis. This provides the sponsor with experienced, impartial quality control that ensures compliance with project specifications.
