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.

Applications now open for ATSSA 2019 Leadership Program

Inspire. Motivate. Empower.

Be a leader in the roadway safety industry and develop your skills by participating in ATSSA’s 2019 Leadership Program.

The three-day training is for ATSSA members only and will be held April 28-30, 2019 in Arlington, Virginia, offering an opportunity for industry leaders to recognize the potential of their organization, utilize the experience of employees in the organization, and improve performance management and efficiencies.

Participants in the training will learn about different leadership styles, discover their own style, grow their business through professional development and network, and learn skills that they can take back to their organizations in the common goal of saving lives on our nation’s roadways.

“I could probably start applying a lesson from each module we did. I realized I did a lot of day dreaming when talking to people. To be able to understand that and then consciously start working on actively listening to my employees and create better interactions with the people I’m working with is very useful,” said a 2017 Leadership Program participant.

Modules for the 2019 program include leadership styles, association governance and strategic planning, personal communications, advocacy, and public relations and the media.

“The best quality of [the presenters] was that they were an expert in their field and they not only taught it, but they lived it. It’s always best to learn from somebody who has had to utilize their own training,” said a 2017 Leadership Program participant.

While participants are not required, those in the program are encouraged to attend ATSSA’s 2019 Legislative Briefing & Fly-In immediately following the program May 1-2 in Washington, D.C., to meet with legislators and advocate for roadway safety infrastructure investment.

The deadline to apply for the program is December 31, 2018. To learn more about this ATSSA member program, or to apply, visit
