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.

ATSSA endorses Auto Alliance’s commitment to preserve bands of spectrum for transportation safety

Pam 0 1325 Article rating: No rating

ATSSA President & CEO Stacy Tetschner sent letters to Federal Communications Commission Chair Ajit Pai and U.S. Department of Transportation Secretary Elaine Chao this week strongly endorsing the Alliance for Automotive Innovation’s letter committing to fully utilize the bands of spectrum allocated for transportation safety.

“The commitment undertaken by the Auto Innovators reflects a watershed moment for roadway safety. This letter demonstrates a unified industry committing substantial resources and support for Vehicle-to-Everything (V2X). This approach should dispel any notion that the industry will not deploy V2X or that the Safety Spectrum will not be used,” Tetschner wrote.

FCC extends deadline for replies to comments on 5.9 GHz band proposal

Pam 0 1558 Article rating: No rating

The Federal Communications Commission’s Office of Engineering and Technology granted a 21-day extension of the deadline for submitting replies to comments regarding a proposed rule change regarding the 5.9 GHz band, also commonly referred to as the "safety spectrum."

The new deadline of April 27 resulted from the extensive comments submitted and disruptions caused by COVID-19.

ATSSA 'steadfastly opposed' to FCC reallocation of 5.9 GHz band

Association files statement with Federal Register outlining its safety concerns

Pam 0 1707 Article rating: 2.0

ATSSA is "steadfastly opposed" to the Federal Communication Commission's plan to reallocate a portion of the 5.9 GHz band of spectrum to other uses out of concerns for "safety and security," President & CEO Roger Wentz said in a statement filed this week with the Federal Register.

People have until March 9 to submit comments and until April 6 to post replies to the proposal, first announced by FCC Chairman Ajit Pai at a Nov. 20 meeting with Citizens Against Government Waste, New America’s Open Technology Institute, and WifiForward.
