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 passes Inflation Reduction Act; House could vote this week

The U.S. Senate passed the Inflation Reduction Act over the weekend, a sprawling bill centered around health care provisions, corporate tax increases and climate provisions, sending the bill to the House, which is expected to approve the legislation later this week.

Within the 775-page bill, ATSSA members will also see a nearly $1.9 billion competitive grant program aimed  at improving walkability, safety and increasing affordable transportation options. The program includes eligibilities to build or improve complete streets, multi-use trails, regional greenways or active transportation networks and spines, while also including safety improvements for vulnerable road users as an eligible activity.

ATSSA will continue to follow the legislation and provide updates as it moves through Congress.
