Development Guidance for Sign Design Standards (0-6363-1)

Many of the design practices that Texas Department of Transportation (TxDOT) uses for large and small sign mounting were established many years ago. These mounting details may no longer be appropriate, given changes in sign materials, fabrication methods, and installation practices. Further, the vehicle fleet and operating conditions on our highways have changed considerably, and there is a need to assess the compliance of some existing sign support systems with current vehicle testing criteria, and to evaluate new technologies that offer to enhance performance and maintenance. This two-year research project was designed to provide TxDOT with comprehensive review and update of mounting details and standards for large and small sign supports, and to provide a mechanism for TxDOT to quickly and effectively evaluate and address high priority needs related to sign support systems. The information provided through the project will be used to update standard Sign Mounting Detail (SMD) sheets, revise or set policies and standards, and evaluate new products and technologies. The issues researched under this are formulated on an annual basis, with the ability to modify priorities as needed.
