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.

TRIP releases updated state-by-state safety statistics

TRIP, a national transportation research nonprofit, has released updated statistics for its latest report on traffic fatalities and serious injury crashes nationwide.

The new information provides the latest statistics for each state to accompany its June report, “Addressing America’s Traffic Safety Crisis: Examining the Causes of Increasing U.S. Traffic Fatalities and Identifying Solutions to Improve Road User Safety.”

The updated information is available in the form of downloadable fact sheets for each state and includes information about each state’s surface transportation system and federal funding.

The report released June 21 showed that the high number of traffic fatalities and serious-injury crashes over the past three years took a significant toll on the nation in both lives lost and economic costs.

Utilizing data from a 2023 National Highway Traffic Safety Administration (NHTSA) report, TRIP estimated that fatal and serious traffic crashes in the U.S. in 2022 caused a total of $1.9 trillion in “societal harm,” including $465 billion in economic costs and $1.4 trillion in quality-of-life costs.
