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.



Touch down in Phoenix for ATSSA’s event of the year

It's not too late to register and get your name on the roster

Yes, there was a big event in Phoenix yesterday but could those guys tackle roadway safety solutions?

Could their front line mount an effective defense against work zone incursions? Could their offensive coordinators come up with a plan to integrate pavement markings and connected vehicle technology?

No, but roadway safety fans can find strategies for those issues and many more in Phoenix Feb. 17-21 at ATSSA’s biggest event of the year – the 53rd Annual Convention & Traffic Expo.

Attendees will score big through interactions with industry experts, networking opportunities, nearly 50 education sessions and by exploring the 200,000-square-foot exhibit hall (more than triple the size of the gridiron) where new and powerful lifesaving devices will be displayed.

In addition, NFL coaches as well as industry managers could benefit from organizational leadership expert Scott Wozniak, ATSSA’s keynote speaker on Feb. 19. He will draw on his experience advising organizations of all sizes across six continents including Silicon Valley start-ups. Plus, he will bring lessons gained from his experience with everything from Fortune 500 companies to family enterprises to a stint at Chick-fil-A headquarters.

In his message, “Great Brands Have Great Employees – The Engine Behind Legendary Companies,” Wozniak will explain how to build an “employee engagement engine” and thus create a winning team.

Registration is still open for the Convention & Traffic Expo where roadway safety and innovation intersect so get your name on the roster before it’s too late.

The event lineup also includes:

  • A Legislative Insights Forum on Feb. 20 featuring former Rep. Bill Shuster, who represented Pennsylvania’s 9th Congressional District for more than 17 years and chaired the House Transportation and Infrastructure Committee. Shuster is currently a senior policy advisor at Squire Patton Boggs, providing strategic advice and consulting on issues including transportation, infrastructure and local governments.
  • The New Products Rollout where 18 companies put their new ideas for advancing roadway safety in front of the industry and a panel of judges made up of department of transportation (DOT) officials. From this group of products, one Innovation Award winner will emerge, with the potential for additional honorable mentions.
  • ATSSA’s Circle of Innovation on Feb. 21 will be the “Solutions Edition,” with DOT officials sharing what is working and what they need from ATSSA members to address issues. The session will also include a presentation on the product that captured the Innovation Award.
  • The announcement of three national awards, which this year include the Industry Achievement Award, the National Safety Award and the Mark of Excellence Award.
