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 congratulates Bhatt on FHWA confirmation

Transportation veteran confirmed as FHWA leader

Shailen Bhatt, who led state transportation departments in Colorado and Delaware, was confirmed by the Senate to lead the Federal Highway Administration (FHWA).

Bhatt’s confirmation by the full Senate on Thursday follows bipartisan support on Nov. 29 by the Senate Environment and Public Works Committee.

As head of the FHWA, Bhatt will oversee implementation of the $1 trillion Infrastructure Investment & Jobs Act (IIJA) passed into law in November 2021.

“We congratulate Administrator Bhatt on his confirmation and look forward to working with him as he carries out the critical work of implementing the IIJA,” said ATSSA President & CEO Stacy Tetschner. “This legislation is critical to advancing roadway safety and efforts to move Toward Zero Deaths. We are pleased to have a leader in place who has led two state departments of transportation and intimately understands the challenges and importance of transportation infrastructure.”

Bhatt most recently served as senior vice president of Global Transportation Innovation and Alternative Delivery at AECOM, an international infrastructure consulting firm, according to the White House announcement of his nomination. Prior to that, he led the Colorado Department of Transportation (CDOT), the Delaware Department of Transportation (DelDOT) and was appointed by former President Barack Obama to serve in the U.S. Department of Transportation (USDOT). He has also served as CEO of the Intelligent Transportation Society of America (ITS America), chaired both the board of the National Operations Center of Excellence (NOCoE) and the Executive Committee of the I-95 Corridor Coalition, and was a member of the World Economic Forum’s Global Agenda Council on the Future of Automotive and Personal Transport. He also served as a member of the Aurora Safety Advisory Board for autonomous driving.
