Installation of Dynamic Travel Time Signs and Efforts to Obtain and Test a Graphical Route Information Panel (GRIP) Sign in Austin

Graphic Route Information Panel (GRIP) signs use a combination of text, colors, and representative maps of the roadway system to convey real-time roadway congestion location and severity information. The intent of this project was to facilitate the fabrication, installation, and onset of operations of three dynamic travel time signs and one GRIP sign on Interstate 35 (I-35) near Austin, Texas. Unfortunately, the Federal Highway Administration (FHWA) rejected the request-to-experiment with a GRIP sign. This report documents the efforts made and accomplishments achieved under this project.
