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 awards Sen. Inhofe as Roadway Safety Champion

(Washington, D.C.) – The American Traffic Safety Services Association (ATSSA) presented its prestigious Roadway Safety Champion Award to Sen. James Inhofe (R-OK). Inhofe was awarded May 3, during the first day of ATSSA's Legislative Briefing and Fly-In, which Rep. Earl Blumenauer (D-OR), Rep. Val Demings (D-FL), Rep. Brendan Boyle (D-PA) and Rep. Dan Lipinski (D-IL) also attended.

"ATSSA's approximately 1,500 members applaud Sen. Inhofe's steadfast leadership in ensuring that roadways in the United States are as safe as possible," ATSSA President and CEO, Roger A. Wentz, said.

Inhofe, a former chairman of the Environment and Public Works Committee and current senior member of the committee, has been a longtime leader on roadway safety infrastructure issues.

"ATSSA leads the nation in roadway safety and I am honored to receive this recognition,” Sen. Inhofe said. “Roadway safety is critically important and one of my top priorities as a leader on the Environment and Public Works committee. As Congress gears up for its next infrastructure initiative, I remain committed to working with my colleagues on this bipartisan issue."

Additionally, Inhofe's work on the last three surface transportation bills have been transformative for the safety of all roadway users.

"Sen. Inhofe's perseverance in moving forward a long-term highway bill - the FAST Act - was crucial in ensuring that roadway safety infrastructure projects are being deployed throughout the country. Lives are being saved today because of the legislation spearheaded by Sen. Inhofe," ATSSA Vice President of Government Relations, Nate Inhofe AwardSmith, said.
