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 10328 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."

Think you’ve got the goods to wow the judges at the New Products Rollout? Here’s your chance.

Applications are now open for members wanting to enter their innovations in the New Products Rollout at the 51st Annual Convention & Traffic Expo. Products released after Jan. 1, 2020 to qualify. All new innovations will be accepted for the New Product Listing, but only 12 will be accepted for presentation to a panel of judges. The top three products will earn an Innovation Award that will be announced during the Convention, which will be held virtually in Feb 8-12 and 16-18.

“The New Products Rollout offers members the opportunity to get their creative ideas to roadway safety issues in front of thousands of people who take part in ATSSA’s Convention & Traffic Expo,” said ATSSA Director of Innovation & Technical Services Eric Perry. “The exposure provided by this event is unparalleled.”

The Transportation Research Board (TRB) Roadside Safety Design Committee and the American Association of State Highway and Transportation Officials (AASHTO) Technical Committee on Roadside Safety met Monday with a focus on implementation and updates for the Manual for Assessing Safety Hardware (MASH).

AASHTO announced that it is working on a scoping project intended to determine the effort it needs to invest to convert MASH into a set of performance specifications, said ATSSA Vice President of Member Services Donna Clark.

Clark, Director of Innovation & Technical Services Eric Perry, and Training Program Manager Jessica Scheyder took part in TRB’s virtual summer conference, which covers a broad range of topics and continues through Aug. 13.
