The objective of this research is to develop a report on current, statewide Oversize/Overweight (OS/OW) truck operational trends in cooperation with the Texas Department of Motor Vehicles (TxDMV) that uses updated data and supports the goals of the most recent Texas Freight Mobility Plan (TFMP). This effort will build off the prior 2016 OS/OW analysis update conducted by TTI which was based upon statistics through December 2014. TTI is working with TxDMV to gain additional data for the period since 2014 to the present. Understanding O-D pairs and flows of OS/OW trucks within the state is key for TxDOT to effectively plan for all freight movement in the state. The movements of OS/OW trucks near ports and other freight generators and along priority corridors can impact greatly both other standard freight loads and passenger traffic. Size, performance, and frequency of OS/OW trucks can also determine design and construction standards along routes to provide acceptable statewide freight networks that can accommodate such movements.
