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 announces strategic reorganization

Realignments and promotions allow ATSSA to better serve membership

FREDERICKSBURG, Va. (Dec. 7, 2020) – ATSSA President & CEO Stacy Tetschner announced a realignment of two of the Association’s vice presidents to better serve its members and most effectively address the multitude of vital issues facing the roadway safety infrastructure industry.

“This decision was made to address the many issues we face as an industry devoted to working toward zero deaths. I wanted to best utilize the talented people we have on our team,” Tetschner said.

Nate Smith’s role will expand to include Member Engagement as he continues leading ATSSA’s Government Relations strategy. Under the new title of Vice President of Engagement, Smith will supervise membership recruitment, retention, member services and chapter management.

He will continue leading the Association’s advocacy efforts at both the federal and state levels and oversee enhanced coordination among the chapter associate directors and the Government Relations Team.

Donna Clark becomes Vice President of Education and Technical Services. In this new role, she oversees ATSSA’s Training, Education, Innovation & Technical Services, Meetings & Conventions, and Customer Success Center as well as The ATSS Foundation. Her focus will be on continued growth and development in these critical areas.

In addition to these changes, Lori Diaz was promoted to director of The ATSS Foundation and Lesly Green’s role was expanded, giving her the title of Director of Board and Volunteer Services while maintaining her role Executive Assistant to the President and CEO.

All changes go into effect today.

“I’m very excited about this new Engagement role,” Smith said. “ATSSA’s members are critical for the success of our advocacy strategy, and a successful advocacy program is crucial for the health of our member companies and for roadway safety across the country. Building stronger bridges among state capitals, Washington, D.C., and our members is going to be integral to the success and vitality of the roadway safety infrastructure industry. But more than that, our members are on the front lines of infrastructure investments each and every day, and I am thrilled to be able to lead ATSSA’s efforts to support them and their businesses as they dramatically enhance the safety of roadway users and work zone workers from coast to coast.”

Clark was equally excited about undertaking her new role.

“I am very excited to be afforded an opportunity to more closely focus on the continued growth and development of our education, training and technical services issues as well as The ATSSA Foundation,” Clark said. “These areas are of great importance, not only to our membership, but also to the entire roadway safety infrastructure industry and I look forward to devoting my time to ensuring that ATSSA is at the forefront of these efforts.”
