Cooperative Automated Transportation (CAT)

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.

Roadmap to Vehicle Connectivity

Anonym 0 0 Article rating: No rating

Manufacturers, technology providers, and national and regional governments have invested billions of dollars in connected and autonomous vehicle research, pilots and demonstrations. Underlying the potential success for these important life-saving technologies is the need for communications infrastructure and interoperability. The questions invariably remain: what communications technology best serves the most? Who will build the infrastructure on which it will operate? Who will pay for it? Building that infrastructure will, in large measure, be the responsibility of the private sector pursuing communications business opportunities.

The National Highway Traffic Safety Administration (NHTSA) requested comments on “Removing regulatory barriers for vehicles with automated driving systems”. This request for comment (RFC) focused on the interior design of automated vehicles including the driver seating position. The document below outlines ATSSA’s response to the RFC, and highlights the lead time needed for a human to regain control of the vehicle, and stressed the importance this has on the safety of our roadway workers.
