Review and Evaluation

TxDOT product evaluation process information can be found in the RTI Research Manual, Chapter 10.

If a need for the product is determined by initial evaluators, the product evaluation administrator will contact you with next steps for a field evaluation. The installation and evaluation shall be performed with TxDOT’s oversight and direction. TxDOT shall provide a location, to be agreed upon, and if needed, traffic control.

The timeline for TxDOT to complete an evaluation varies widely. It is influenced by many factors, including the type of product being evaluated.
