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.

Prepare for Convention 2023 where roadway safety & innovation intersect

Registration now open for ATSSA’s Convention & Traffic Expo in Phoenix

ATSSA’s 53rd Annual Convention & Traffic Expo will bring roadway safety experts and innovators from across the nation and the world to Phoenix, Feb. 17-21.

This five-day event will once again be the site of the largest gathering of the roadway safety infrastructure industry in North America and feature information on the latest advances, provide a look at the latest innovative products, offer dozens of education sessions and access to countless experts from all facets of the industry.

The event will also include a massive display of devices to keep roadway workers and the motoring public safe, all situated on the 226,300-square-foot Traffic Expo floor inside the Phoenix Convention Center.

The ATSS Foundation will again hold its popular golf and sporting clays events, plus there will be additional opportunities for networking through special events for groups such as the Young Industry Professionals.

The 2023 Convention & Traffic Expo is where roadway safety and innovation intersect.

“The 2023 Convention will expand on the great experience we enjoyed in Tampa this year where thousands reunited for roadway safety after two years of virtual events,” said ATSSA President & CEO Stacy Tetschner. “This year’s event reinforced the value of gathering in person where there are ample opportunities to collaborate with others in addressing such significant issues as materials shortages, workforce challenges and roadway worker protection. I look forward to gathering in Arizona to again experience that synergy and continue advancing roadway safety.”

The Convention will include committee and council meetings, general sessions, education sessions, a legislative update, the New Products Rollout, Circle of Innovation, the announcement of national awards and countless opportunities to network with industry insiders from public agencies and private industry.

Registration opens July 11. Book your hotel first to get the discounted registration rate.
