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.

Discounted registration ends soon for ATSSA’s 50th Annual Convention & Traffic Expo

Sponsorships still available for Foundation events

Don’t forget to register for ATSSA’s 50th Annual Convention & Traffic Expo, which runs from Jan. 24-28 in New Orleans.

This event celebrates a half century of advances in roadway safety infrastructure and features the Chairman’s Reception and Gala on Jan. 25. The gala includes live music, a sit-down dinner and the announcement of award winners in several categories such as the Industry Achievement Award. Dress is business attire with black tie optional.

The discounted rate ends Jan. 6 so you’ll want to register soon.

Also, it’s not too late to sign up for The ATSS Foundation’s Inaugural Fun Run, which takes place on Jan. 26 at the Audubon Aquarium of the Americas. The course is conveniently located near the Ernest N. Morial Convention Center where most of the expo events take place. The two-mile run is great for runners and walkers of all skill levels.

Space is also still available for the Sporting Clays Event but the Golf Classic Tournament is full.

Sponsorships are still available for all three events. Funds raised through these events 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.

Join the thousands who will be in attendance for North America’s largest roadway safety infrastructure trade show. Come learn from experts, collaborate with your peers and celebrate our golden anniversary.

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).

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.

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.
