The Technical Assistance Center (TAC) was established to serve our members with information regarding the application, interpretation, revision or status of strategic highway safety plans (SHSP), standards, manuals, and guidelines addressed in industry related documents such as the MUTCD, NCHRP Report #350, Roadside Design Guide and other documents.
ATSSA’s web pages offer a variety of tools to help you discover the latest news on technology in the roadway safety community and serves as electronic clearinghouse of technical issues that affect you, the Roadway Safety professional.
Another area that is fast developing into our industry’s primary resource for knowledge on sign and pavement marking luminance is the retroreflectivity.net website. With the active participation of our members, this site is rapidly becoming an electronic clearinghouse of retroreflectivity issues.
ATSSA’s Resource Center staff regularly attends and actively participates in numerous industry meetings and conferences to continually advocate our message of Safer Roads Save Lives and to continually be informed of the latest developments so that ATSSA will be recognized as the authority on roadway safety issues.

April 9, 2007: The FHWA proposes to require accreditation of laboratories that conduct crash tests on roadside hardware (including crash testing of TCD) by an accrediting body that is recognized by the National Cooperation for Laboratory Accreditation (NCLA) or another comparable accreditation body approved by FHWA.
FHWA published a final rule on November 24, 2006 (in response to Section 1402 of SAFETEA-LU) that establishes a new Part in Title 23 CFR that requires workers to wear high-visibility safety apparel while working on or near Federal-aid highways.

Synthesis of Non-MUTCD Traffic Signing
The purpose of this synthesis (148-pg 21MB) was to collect information on special (non-MUTCD) sign legends, designs, and symbols used by State DOTs and by selected large cities and counties. The synthesis also identifies commonalities, such as what special conditions are the most common reasons for developing a special sign and what design elements have been most commonly used to communicate the message, and to determine the most likely candidate sign legends and symbols for potential future addition to the MUTCD.
