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 updated Training & Products Catalog now available

ATSSA’s redesigned and updated Training & Products Catalog is now available online.

“The ATSSA Training & Products Catalog is a valuable tool for our members and anyone in the roadway safety industry in need of training to operate effectively in work zones and elsewhere,” said ATSSA Training Program Manager Jessica Scheyder. “The catalog also includes information on the benefits of ATSSA membership, the Corporate Training Program, certification and recertification, courses offered through grants and the Online Training Library.”

The catalog includes a list of courses applicable nationwide as well as state-specific courses offered by ATSSA. It also includes a list of valuable tools such as a Flagger Handbook and a copy of the Manual on Uniform Traffic Control Devices (MUTCD).
