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.

Today, Cindy Williams, president of Time Striping, president of the Arkansas ATSSA Chapter, and a member of the ATSSA Board of Directors, testified before the Highways and Transit Subcommittee in the House of Representatives on Capitol Hill.

The hearing, entitled “Addressing the Roadway Safety Crisis: Building Safer Roads for All,” focused on the recently released 2021 traffic fatality statistics, and countermeasures that can combat that increase.

“The Highway Safety Improvement Program (HSIP) is a critical component to achieving the goal of Towards Zero Deaths,” Williams said in her testimony. “Having a dedicated funding stream for roadway safety has been critical to addressing safety needs and continuing this program was a bipartisan priority for Congress and ATSSA.”

Discussion during the hearing also focused on rural road safety, something Williams said she understands well from her experience in Arkansas.
