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 votes unanimously to redistribute a portion of the safety spectrum

ATSSA and other roadway safety advocates opposed changes to 5.9 GHz band

Pam 0 1245 Article rating: 5.0

The Federal Communications Commission (FCC) voted unanimously today to reallocate more than half of the 5.9GHz spectrum band—known as the “safety spectrum”—to unlicensed uses including WiFi.

The new rules adopted today make the lower 45 megahertz of the spectrum available for unlicensed uses. They require Intelligent Transportation System (ITS) licensees to stop using this portion of the spectrum within a year.

ATSSA President & CEO Stacy Tetschner called the action "a major blow to the roadway safety community and public safety in general."

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

Pam 0 2372 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.

Highway automation: How ATSSA members play an important role

CAVs will need to better communicate with roadway devices and infrastructure

SuperUser Account 0 2802 Article rating: No rating

Connected and Automated Vehicles (CAVs) rely heavily on ATSSA member products such as pavement markings, signs, and traffic control devices. These products will be an essential factor in the advancement of CAVs and critical in moving toward zero deaths on our roadways.
 

Sensor technology in roadway infrastructure

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

SuperUser Account 0 7825 Article rating: No rating

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.
