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.

Senate approves stopgap funding resolution

Update: President Trump signed the extension Friday night (Dec. 11).

Earlier this afternoon, the Senate voted to pass a stopgap Continuing Resolution (CR) that would keep the government funded through Dec. 18 and avoid a potential government shutdown. In September, Congress had voted to extend the deadline for the passage of the annual government funding bill to midnight tonight. The House passed the week-long extension on Wednesday by a margin of 343-67, while the extension passed through the Senate on a voice vote today. The CR now goes to the desk of President Trump, where he is expected to sign it. This leaves Congress with one week to work out the details of the spending bill prior to the holidays, with issues on COVID relief and the FY21 budget acting as the main sticking points in negotiations.

The previous stopgap spending extension contained the one-year extension of the Fixing America’s Surface Transportation Act (FAST Act).
