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.

ATSSA hosts Ohio “How To” workshop in Columbus for roadway safety professionals

Educational workshop discusses latest in transportation industry topics

As part of the American Traffic Safety Services Association’s (ATSSA) ongoing work as the leader in roadway safety infrastructure, the association is holding an Ohio “How To” Training and Education Workshop in Columbus, Ohio on April 10, 2019.

The training and education workshop will be held at the Marriott Columbus in the university area.

During the workshop, roadway safety professionals will have discussions on the latest topics in the transportation industry, including highway infrastructure funding, MASH implementation, Connected Automated Vehicles, and smart work zones. Participants will also learn about Ohio Department of Transportation’s new safety training.

The conference is a must for government employees, contractor employees, consulting engineers, and manufacturers and suppliers involved in the selection, inspection, and maintenance of all types of pavement marking products, signs, and temporary traffic control devices.

“We’re excited to have roadway safety professionals from Ohio and the surrounding area attending our Ohio ‘How To’ workshop. ATSSA is committed to leading the roadway safety infrastructure industry, and events where we can share information with these professionals makes a difference in our mission to advance roadway safety,” said ATSSA’s Director of Meetings & Conventions Necoya Tyson.

Registration for the event is still open. For more information on the Ohio “How To” Training and Education Workshop, visit
