• Abstract:
  The travel demand models developed and applied by the Transportation Planning and Programming Division ; (TPP) of the Texas Department of Transportation (TxDOT) are daily three-step models (i.e., trip generation, trip ; distribution, and traffic assignment sequentially invoked). Currently, TxDOT TPP does not have a procedure to ; account for existing or planned toll roads in the urban travel demand models. TxDOT TPP has been operating under ; guidance established when toll roads existed as planned facility improvements in either the interim or forecast year ; model applications. Although the larger urban areas in Texas have embraced tolled facilities for quite some time (i.e., ; Dallas-Fort Worth, Houston, and Austin), roads that charge users a fee to bypass congestion or provide alternative ; routes have only been implemented recently in a select few small to medium-sized urban areas still under the purview ; of TxDOT TPP model development. In order to calibrate base year travel models with operational toll roads or models ; with planned tolled facilities, TxDOT TPP needs a procedure to account for facilities that charge fees to the user. For ; the tolled facilities currently operational in small to medium-sized study areas, the fees are fixed and are not dynamic ; by time of day or congestion levels. ; The technical objective of this research report is to provide TxDOT TPP with a menu of potential procedures ; that could be selected for implementation in the current Texas Package suite of travel demand models to reasonably ; estimate toll road demand, primarily for the small to medium-sized urban areas. Nationally, generally two approaches ; are used: a path-based system and a choice-based system. Researchers reviewed both approaches as well as different ; supplemental techniques (i.e., time of day, market segmentation, and mode choice) implemented nationally and within ; the state that are complementary to any toll demand estimation techniques. Challenges and considerations for each of ; the approaches are reviewed and presented. The procedures and applications reviewed in this project are not intended ; to replace or compete with existing toll-financing-level analysis.
