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.

Midyear Digital: Hear national experts’ short- and long-range industry forecasts

Opening General Session will reveal “6:60:6 Predictions”

Midyear Digital’s Opening General Session features a panel of national experts providing their “6:60:6 Predictions” for the roadway safety industry.

Below are the panelists and their topics:

  • Ken Simonson, chief economist, Associated General Contractors of America - A 6-12 month economic forecast for the construction industry
  • Jeff Davis, senior fellow and editor, Eno Transportation Weekly - A 60-month forecast for transportation funding
  • Hilary Cain, vice president, Technology, Innovation, and Mobility Policy, Alliance for Automotive Innovation - A 6-year forecast for connected and autonomous vehicle technology (CAV)

“I’m excited about the panel we have assembled and look forward to engaging the participants in a lively conversation about ‘what’s next,’” said ATSSA Vice President of Government Relations Nate Smith. “Each panelist is well-positioned to provide unique insights about the future and its impact for our industry, which will give ATSSA members the tools necessary to strategically and financially plan for the near- and long-term future.”

This year’s Midyear Meeting has gone fully virtual while retaining the critical components that make this gathering important to members of the roadway safety industry. The Aug. 24-27 event includes Committee and Council meetings, an ATSSA PAC Reception, and networking opportunities to include coffee and social hours.

Registration is now open.

Because attendance by key public agency and transportation officials is important to ATSSA, the Association is offering them complimentary registration. Interested public agency officials can request a registration code by emailing
