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.

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.

His 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 '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.

Sensor technology in roadway infrastructure

How devices are strengthening the lines of communication between human and automated drivers

For many departments of transportation (DOTs), the collection and sending of real-time traffic data to roadway users is high priority. One way agencies nationwide are achieving this goal is through the use of sensor technology in roadway infrastructure, such as pavement markings or signs, allowing them to strengthen Vehicle-to-Infrastructure (V2I) communication.
