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.

ONLINE NOW: Phoenix offers a glimpse into the AV future

Fall issue of Roadway Safety magazine includes supplement on Worker Protection

When ATSSA members arrive in Phoenix for the 2023 Convention & Traffic Expo in February they will find themselves in a city that’s made a name for itself as a pioneer in the testing of autonomous vehicle (AV) technologies.

The region has embraced the technology and seen multiple pilots for grocery delivery as well as a driverless taxi service.

The Fall issue of Roadway Safety magazine—available online now—details these efforts in Arizona and:

“Worker Protection” is the subject of a supplement that accompanies the Fall issue. As the cover proclaims, Roadway Worker Protection is everyone’s business and this issue explores:
