Road Sign

Signs are important fixtures that help advance roadway safety every day throughout the United States. Today, a variety of symbols, shapes and colors are used to convey messages to users on and around the roadways. Signs types include traffic, roadway, warning, railroad, guide, recreational, temporary, regulatory, pedestrian and bicycle.


There are many benefits to using symbols, which include immediate communication with all roadway users and their ability to break language barriers. Colors can communicate approaching scenarios such as using orange to indicate an upcoming work zone or red for an upcoming stop or yielding point. A number of shapes are also used to indicate oncoming situations or to provide roadway users with information such as octagons for stop and long horizontal, rectangular signs displaying guidance information.


Today, traffic signs are being looped into the world of autonomous driving technology. Research efforts are being made to equip traffic signs with technology, like embedded machine-readable codes, to allow them to communicate with Connected Automated Vehicles (CAVs) and other mapping devices.


ATSSA has dedicated group of members on its Sign Committee (member login required), who work to:

  • Enhance members’ businesses by increasing their understanding of traffic control devices on private property,
  • Influence the present and future direction of Minimum Retroreflectivity Standards,
  • Inform and educate roadway safety industry members on sign industry-related matters,
  • Provide knowledge and education about signing retroreflectivity,
  • Work to have dedicated funds identified and available for sign management systems and the implementation of upgraded programs to conform with MRS,
  • Monitor and influence the development of a new MUTCD chapter on changeable message signs, and
  • Improve upon and solicit greater committee member participation in Sign Committee meetings and on task forces, including recruitment of new committee members.

ATSSA endorses Auto Alliance’s commitment to preserve bands of spectrum for transportation safety

ATSSA President & CEO Stacy Tetschner sent letters to Federal Communications Commission Chair Ajit Pai and U.S. Department of Transportation Secretary Elaine Chao this week strongly endorsing the Alliance for Automotive Innovation’s letter committing to fully utilize the bands of spectrum allocated for transportation safety.

“The commitment undertaken by the Auto Innovators reflects a watershed moment for roadway safety. This letter demonstrates a unified industry committing substantial resources and support for Vehicle-to-Everything (V2X). This approach should dispel any notion that the industry will not deploy V2X or that the Safety Spectrum will not be used,” Tetschner wrote.

“The bands of spectrum allocated for transportation safety has and will continue to make an impact on roadway safety. Some studies suggest that up to 94% of the vehicle crashes occur because of human behavior, which includes speeding and distracted driving. In the future, as automated vehicles penetrate the marketplace, these vehicles will also communicate utilizing the spectrum to save even more lives. The deployment of these types of technologies takes time, and more time is needed to allow these technologies to fully utilize the Safety Spectrum to save lives."

In December, the Federal Communications Commission (FCC) voted unanimously to look at reallocating the 5.9 GHz band of spectrum—a wireless band commonly referred to as the “safety spectrum,” which was set aside in 1999 for traffic-safety-related purposes.

The FCC’s proposal would open 45 out of 75 megahertz of this spectrum to “unlicensed uses” such as WiFi hotspots and other expansions of wireless broadband services. The upper 30 megahertz would remain reserved for transportation safety uses.

ATSSA, AASHTO, the Defense Department and the Alliance for Automotive Innovation (Auto Alliance) are among the groups opposing the FCC’s plan.

“Vehicle-to-everything (“V2X”) communication technologies promise to deliver significant safety and societal benefits to the American public, including reducing automotive crashes and fatalities and producing economic, environmental, and transportation efficiencies,” Auto Alliance President & CEO John Bozella said in a letter Thursday to Pai and Chao. “Recognizing the opportunity for these benefits, automotive manufacturers have already deployed or announced deployments utilizing the 5.9 GHz Safety Spectrum band in the United States (U.S.) and around the world.”

The Auto Alliance also issued a statement on Thursday outlining its position.

In his letter, Tetschner a highlighted the “significant investment by both the private industry as well as taxpayer dollars. According to the USDOT, there is currently over $1.5 billion in taxpayer-funded investments in over 25 states with substantial V2X deployments. This fact, combined with the Auto Innovators’ commitment to deploying 5 million radios, ensures that the network will realize the maximum safety benefits of V2X if the FCC assures that all 75MHz of Safety Spectrum will be maintained for transportation safety and takes action to permit cellular vehicle-to-everything (C-V2X).”
