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.

Automated vehicles will be mainstream in the next decade, members of an Innovation Panel predicted today during the first general session of ATSSA’s 51st Annual Convention & Traffic Expo.

Timothy Drake, vice president of public policy and regulatory affairs at ITS America, said he expected trucking fleets and public transportation would be the first to take that step and be in place in the 2030s. With that in mind, he said planning needs to take place now within jurisdictions across the country and state departments of transportation (DOTs).

Nazila Roofigari-Esfahan, an assistant professor at Virginia Tech, agreed with Drake but said she hoped it wouldn’t take place before people are ready for it. She said both infrastructure and individuals need to be prepared for that shift in transportation.

The Innovation Panel was one part of today’s general session at ATSSA’s 2021 Convention & Traffic Expo. The session kicked off with a welcome from Board Chair Greg Driskell and the State of the Association Report by ATSSA President & CEO Stacy Tetschner. That was followed by a State of the Industry panel and announcement of two industry awards.
