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 joins stakeholders in urging Biden to commit to zero fatalities by 2050

ATSSA, along with more than 70 other organizations, sent a letter to President Joseph R. Biden on Wednesday urging him to commit to reaching a goal of zero roadway fatalities by 2050.

“Reaching zero fatalities has been a longtime priority for ATSSA,” said Vice President of Engagement Nate Smith. “Our advocacy work in Washington, D.C. and in state capitals around the country is consistently urging legislators to make progress towards that goal.”

Biden and Transportation Secretary nominee Pete Buttigieg have talked about roadway safety as a priority over the last year or more during the campaign. Other groups joining ATSSA on the coalition letter include AAA, AASHTO, American Trucking Associations, ITS America and the National Association of City Transportation Officials (NACTO).
