A Snapshot of Travel Modeling Activities: The State of Texas

The Texas Department of Transportation (TxDOT) has been involved in model development and travel model activities since the early 1960s. With the implementation of the Surface Transportation Act in 1962, TxDOT became the lead travel demand model developer in the state for all urban areas greater than 50,000 in population and continues to be the lead model developer for 23 of the 25 urban areas in the state. There are three main aspects in TxDOT’s approach to modeling that have been an underlying motif throughout the ensuing decades and that inform the structure of this report; these are: software independence, commitment to data collection, and support of research and model enhancements. This snapshot focuses on TxDOT’s current activities and begins with a brief history of modeling in the state. Following the brief history, the current state of modeling in Texas is summarized followed by a discussion of on‐going data collection activities that support travel model development in the state. That is followed by an overview of recent and unique Texas model applications. The final section of the report offers a summary of the Texas statewide analysis model (SAM).
