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.

FCC Chair Ajit Pai online Wednesday to discuss connectivity issues

Pai's views on the safety spectrum have roadway safety advocates concerned

Federal Communications Chair Ajit Pai will be the headline speaker at 11 a.m. Wednesday during a live event hosted by The Hill news outlet.

The event, “The Future of Human Connectivity,” is available to the public. People who sign up can also submit a question. People can also email questions to events@thehill.com.

Pai's session runs from 11 a.m. to 12:15 p.m. E.T. and is entitled, “New Lines of Community: What Connectivity Means and What We Still Need.” Bob Cusack, The Hill’s editor-in-chief, will lead the conversation with Pai.

ATSSA is steadfastly opposed to the FCC’s plan to reallocate a portion of the 5.9 GHz band of spectrum known as the “safety spectrum,” to other uses out of concerns for safety and security.

As ATSSA previously reported, many organizations such as the Department of Defense (DOD) and the Intelligent Transportation Society of America (ITS America) have opposed the proposal.

In 1999, the FCC designated the 75 Megahertz (MHz) spectrum in the band for Dedicated Short Range Communications (DSRC), which supports Connected and Automated Vehicles (CAVs), Cellular Vehicle to Everything (C-V2X) technology, and a number of roadway safety infrastructure devices. Pai said at that point that he was “proposing to make available the lower 45 MHz” of the 5.9 GHz band “for unlicensed uses like Wi-Fi.”

In April, ATSSA President & CEO Stacy Tetschner sent letters to Pai and U.S. Department of Transportation Secretary Elaine Chao strongly endorsing the Alliance for Automotive Innovation’s letter committing to fully utilize the bands of spectrum allocated for transportation safety.
