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 is "steadfastly opposed" to the Federal Communication Commission's plan to reallocate a portion of the 5.9 GHz band of spectrum to other uses out of concerns for "safety and security," President & CEO Roger Wentz said in a statement filed this week with the Federal Register.

People have until March 9 to submit comments and until April 6 to post replies to the proposal, first announced by FCC Chairman Ajit Pai at a Nov. 20 meeting with Citizens Against Government Waste, New America’s Open Technology Institute, and WifiForward.

Pam 0 6863 Article rating: 4.0

Work continues on incorporating traffic signals into the Association’s activities to advance roadway safety. In 2019, ATSSA formed a Traffic Signals Committee and new membership category during its Midyear Meeting to ensure that the Association is representing all sectors of the roadway safety infrastructure industry and areas related to the Manual on Uniform Traffic Control Devices (MUTCD). It also will allow ATSSA to move forward with new partnerships with traffic signal installers and manufacturers.
