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.

UPDATE: The full Senate is expected to consider Buttigieg's nomination Tuesday at noon.

The nomination of former South Bend, Ind. Mayor Pete Buttigieg to serve as Secretary of Transportation in the Biden administration received a vote today in the Senate Commerce Committee, in which the committee voted 21-3 to confirm the nomination.

The committee held a hearing on the nomination on Jan. 21. The nomination now moves on to the full Senate to receive a final vote on whether to confirm the nomination.

Senate Commerce Committee Chairman Roger Wicker (R-MS) commented on the passage of the nomination out of the committee.

“I look forward to seeing Pete Buttigieg confirmed by the full Senate and working with him in his new role as Secretary of Transportation," Wicker said. "Transportation issues historically have been addressed on a bipartisan basis,and I expect to continue that practice with Mr. Buttigieg.”

ATSSA will provide an update when the nomination reaches the Senate floor for a vote.
