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.

Recipients of 2019-2020 Roadway Worker Memorial Scholarship announced

Nine awarded scholarships for post-secondary education

The American Traffic Safety Services Foundation (ATSS Foundation) has awarded nine students with the 2019-2020 Roadway Worker Memorial Scholarship.

The scholarship offers educational opportunity to dependents of roadway workers killed or permanently disabled in work zone crashes, by providing recipients with financial assistance for post-high school education.

Scholarships are valued up to $10,000. Applicants with a strong commitment to volunteerism may apply to receive an additional $1,000 Chuck Bailey scholarship.

The ATSS Foundation is a charitable organization that provides support to the loved ones of those impacted by work zone crashes through several programs, like the Roadway Worker Memorial Scholarship. The Foundation also honors those killed in work zone incidents with the National Work Zone Memorial.

“The Roadway Worker Memorial Scholarship program offers a brighter road ahead for those whose lives have been impacted by the tragedy of a work zone incident. The ultimate goal is to achieve our objective of Toward Zero Deaths on our nation’s roadways, but until that objective is achieved, The Foundation serves a vital role of support and comfort,” said ATSS Foundation President David Krahulec of Horizon Signal Technologies.

The following are the 2019-2020 scholarship recipients:
