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.

3M supports The Foundation with Toward Zero Deaths Virtual Pledge Wall

Donations totaled more than $15,000 to support loved ones of roadway workers

FREDERICKSBURG, Va. – 3M’s Transportation Safety Division once again hosted the 3M Toward Zero Deaths Virtual Pledge Wall in support of the American Traffic Safety Services Foundation (ATSS Foundation). Online donations were accepted until Feb. 12—the end of ATSSA's Annual 49th Annual Convention & Traffic Expo—and totaled up to more than $15,000 thanks to the association’s generous supporters and partnering company, 3M.

3M’s virtual pledge wall also allows individuals making a monetary pledge to leave a personalized message or memorial for a loved one, while supporting The Foundation’s mission. This year was the first time that 3M’s pledge wall went virtual, making it easier for individuals to donate online.

“3M was once again honored to partner with The Foundation to sponsor the Virtual Pledge Wall in support of roadway workers and their loved ones,” said 3M’s Global Communications Strategist Heather Swanson. “We are happy to work with The Foundation to help keep its many programs thriving and it is always great to see the generosity of our fellow roadway safety and infrastructure members.”

The Foundation provides support to the loved ones of those impacted by work zone crashes through several programs, including scholarships like the Roadway Worker Memorial Scholarship and the Experience Camps Travel Scholarship. The Foundation also honors those killed in work zone incidents with the National Work Zone Memorial. Funds raised online by the virtual pledge wall are used to support The Foundation’s programs throughout the year.

Foundation President David Krahulec of Horizon Signal Technologies, Inc., spoke to the importance of the virtual pledge wall in supporting the nonprofit’s mission to help the loved ones of those killed or permanently disabled in work zone incidents.

“The Foundation is honored to continue its partnership with 3M and raise thousands of dollars to support roadway workers and their families,” said Krahulec. “This is an important effort that not only highlights the importance of roadway safety but also allows The Foundation to ensure no child, spouse, or any relative of an injured or killed roadway worker is left without support. We’re all in this together, and every step to reach zero deaths on our nation’s roadways is monumental. Thank you again to all those who donated.”
