Cooperative Automated Transportation (CAT)

Cooperative Automated Transportation

Roadway safety in a cooperative automated world

Highway automation is not years away, or even days away. It’s here now, causing a number of state transportation agencies to react with initiatives related to preparing and supporting Connected Automated Vehicles (CAVs) on U.S. roadways.

Connected and Automated Vehicles (CAVs)

Cooperative Automated Transportation (CAT) deals with CAVs, which are vehicles capable of driving on their own with limited or no human involvement in navigation and control. Per the definition adopted by the National Highway Traffic Safety Administration (NHTSA), there are six levels of automation (Levels 0-2: driver assistance and Levels 3-5: HAV), each of which requires its own specification and marketplace considerations.

Vehicle-to-Everything (V2X) and Connected and Automated Vehicles (CAVs)

For traffic safety, vehicle-to-everything communications is the wireless exchange of critical safety and operational data between vehicles and anything else. The "X" could be roadway infrastructure, other vehicles, roadway workers or other safety and communication devices. ATSSA members are at the forefront of these technologies, and are working with stakeholders across new industries to see these innovations come to life.

Sensor Technology

CAVs rely on three main groups of sensors: camera, radar, and Light Detection and Ranging (LIDAR). The camera sensors capture moving objects and the outlines of roadway devices to get speed and distance data. Short- and long-range radar sensors work to detect traffic from the front and the back of CAVs. LIDAR systems produce three-dimensional images of both moving and stationary objects.

ATSSA to celebrate 50 years at 2020 Annual Convention & Traffic Expo

Thousands to convene in New Orleans at North America’s largest roadway safety infrastructure trade show

FREDERICKSBURG, Va. (Dec. 30, 2019) – The American Traffic Safety Services Association (ATSSA) will celebrate its past as it drives the future of the roadway safety infrastructure industry during its 50th Annual Convention & Traffic Expo. This mile-marker event will be held in New Orleans – the same city where the first annual convention was held. The event runs from Jan. 24-28 with most events at the Ernest N. Morial Convention Center.

As the largest roadway safety infrastructure trade show in North America, ATSSA’s convention and expo brings together more than 3,500 business leaders, government officials, manufacturers and corporate roadway personnel from over 50 countries. More than 150 companies will display cutting-edge traffic safety solutions, state-of-the-art roadway safety vehicles and heavy equipment in more than 200,000 square feet of exhibit space at the convention center.

The lineup of 35-plus education sessions on Jan. 27-28 is designed to provide the most beneficial and timely information available in the industry. ATSSA develops these sessions through research and member surveys. Attendees receive 1.25 Continuing Education Units (CEUs) for attending this year's conference and education sessions.

Information sessions also take the form of “Traffic Talks,” which run for 30 minutes throughout the Traffic Expo after the exhibit hall opens on Jan. 26.

New for 2020, attendees can attend Micro Sessions on Jan. 26. These 30-minute sessions are packed with high-caliber content. They use data exchanges to increase work zone safety, improve the understanding of friction data using GPS and imagery, and enhance traffic paint design for Connected and Automated Vehicles (CAVs).

The annual New Products Rollout includes 20 companies and starts on Jan. 26 with the top three products being chosen as winners of the ATSSA Innovation Awards on Jan. 28. The New Products Rollout provides companies the opportunity to show off the latest innovations in the roadway safety infrastructure industry.

ATSSA’s Circle of Innovation will be held Jan. 28 and provides more than 200 state Department of Transportation officials and roadway and safety engineers an opportunity to express their needs to ATSSA manufacturers and installers.

Also new for 2020 is The ATSS Foundation Fun Run, which will be held Jan. 26 at a two-mile course conveniently located to the convention center. The nonprofit, which provides programs that support injured or fallen roadway workers and their families, will also host the 29th Annual Golf Classic Tournament and the 8th Annual Sporting Clays Event on Jan. 24. Event funds support the Roadway Worker Memorial Scholarship Program, the Marty Weed Engineering Scholarship Program, the Experience Camps Travel Scholarship, and The National Work Zone Memorial. The memorial honors roadway workers, motorists and passengers who have lost their lives in a roadway work zone accident. The memorial, which lists nearly 1,500 names, will be displayed on the exhibit floor in Booth #840.

ATSSA was incorporated as an international trade association in 1970. Today, it has more than 1,500 members and has provided training and education to nearly 1 million professionals in the roadway safety infrastructure industry. As ATSSA drives forward into 2020, it remains committed to its members and the roadway safety infrastructure industry with the philosophy, “Safer Roads Safe Lives.”
