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’s 48th Annual Convention & Traffic Expo breaks records

Event continues to be largest U.S. trade show for roadway safety products and services

It was a record-breaking year for American Traffic Safety Services Association's (ATSSA’s) 48th Annual Convention & Traffic Expo, which was held at the Henry B. González Convention Center in San Antonio, Texas, from Jan. 26 to 30. There were 3,464 registered event attendees and 567 booths were sold—making it the largest Traffic Expo in the association’s history. There were also nearly 200 companies exhibiting.

ATSSA’s Annual Convention & Traffic Expo has seen steady growth, climbing 16 percent over a span of five years.

ATSSA’s first trade show was held in 1970, drawing in 150 attendees with about 10 tabletop displays. The event’s meetings, exhibits, and meal functions were held within 8,000 square feet of space. ATSSA's Expo has come a long way since then.

"ATSSA's 48th Annual Convention & Traffic Expo broke records across the board--number of exhibit booths and attendance at the convention and the Opening General Session," said ATSSA’s Director of Meetings & Conventions and The Foundation, Neil Mullanaphy, CHME. "I'm also grateful that The Foundation's Golf Tournament and Sporting Clays Event were sold out again this year thanks to the unwavering support of ATSSA's members."

ATSSA’s Annual Convention & Traffic Expo remains the top event for members of the roadway safety industry. The 2018 Annual Convention & Traffic Expo brought the latest innovative products from exhibitors together in more than 200,000 square feet of exhibit space. This year’s event also offered highly anticipated events including the Chairman’s Reception, Opening General Session, ATSSA Traffic Talks, ATSSA’s New Products Rollout, the ATSSA Innovation Awards, ATSSA’s Circle of Innovation, the 2018 Traffic Control Device Challenge (held in partnership with the Transportation Research Board), and education and informational sessions.

Next year, the event will be held in Tampa, Florida, from Feb. 8 to 12. Subscribe to the ATSSA Blog and follow ATSSA on Twitter and Facebook for additional announcements about the 2019 event.
