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.

ATSSA & TRB announce 2023 Traffic Control Device Student Challenge

Challenge offers opportunity for students to innovate for the future of roadway safety

Fredericksburg, Va. (April 18, 2022) – The American Traffic Safety Services Association (ATSSA) and Transportation Research Board (TRB) Standing Committee on Traffic Control Devices invite students to compete in the 2023 Traffic Control Device (TCD) Student Challenge.

The TCD Student Challenge promotes innovation and stimulates ideas in the traffic control devices industry with a goal to improve operations and safety and encourage future generations of roadway safety professionals. As part of the challenge, individuals or student teams submit solutions in the subject area of transportation and roadway safety based on the chosen topic for the year.

This year’s topic is “Innovative Traffic Control Devices to Improve Vulnerable Road User Safety.”

The TCD Student Challenge is open to high school, junior college, college and university students or teams of students with an interest in transportation and an understanding of traffic control devices. Students in relevant fields such as transportation, human factors and technology-related curricula are particularly encouraged to participate.

“The TCD Student Challenge gives students an opportunity to tackle a real-world transportation issue and apply their knowledge and critical thinking skills to a problem that can help save lives,” said ATSSA Director of Innovation & Technical Services Eric Perry. “With traffic fatalities increasing and deaths for vulnerable road users—such as people on foot, bicycle, scooter or wheelchair—on the rise in both urban and rural areas, this challenge offers a way for students to help us solve this important issue. This contest also offers students a way to showcase their talents before transportation professionals and open career opportunities.”

Participants receive the opportunity to present their designs in a public forum during the 2023 TRB Annual Meeting, set for Jan. 8-12 in Washington, D.C. The top team also wins a $1,500 prize and the opportunity to present its submission at ATSSA’s 53rd Annual Convention & Traffic Expo, set for Feb. 17-21 in Phoenix.

The deadline to submit an application is Oct. 1, 2022. To learn more about the challenge, visit https://www.atssa.com/Technical-Services/Innovation/TCD-Student-Challenge.
