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.

Senate confirms Pete Buttigieg as Secretary of Transportation

The Senate today confirmed former South Bend, Ind., Mayor Pete Buttigieg to serve as Secretary of Transportation, adding him to the cabinet of President Joe Biden.

“ATSSA congratulates Secretary Buttigieg on his confirmation as Secretary of Transportation,” said ATSSA President & CEO Stacy Tetschner. “As the voice of roadway safety, ATSSA members are eager to work with him to significantly reduce the 36,000 men, women and children who die on U.S. roadways annually. Secretary Buttigieg’s commitment to a vision zero strategy and finding a long-term solution to funding the Highway Trust Fund (HTF) matches ATSSA’s top legislative priorities; we look forward to working together to combat roadway fatalities and serious injuries and moving towards zero deaths on America’s roads and streets.”

Buttigieg campaigned on the need for transportation and infrastructure investment throughout his bid to become the Democrats’ nominee for president. During his hearing before the Senate Commerce Committee last month, he touched on the need for shoring up revenue for the HTF, increased investment in tribal and rural roads, the future of autonomous vehicles and the need for safety to be at the forefront of any new transportation or infrastructure initiative.

The Senate Commerce Committee forwarded his nomination to the full Senate on Wednesday by a 21-3 vote.

The full Senate confirmed Buttigieg’s nomination by a vote of 86-13.
