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.

Join roadway safety professionals for ATSSA’s Midyear Meeting to help shape policies and initiatives for the roadway safety infrastructure industry for the coming year.

Network with more than 350 industry professionals from across the country who are gathering in Providence, R.I., to further innovation and infrastructure for roadway safety, Aug. 23-26.

The meeting is tailored to national committee members and friends to learn, network and build leadership skills.

“These meetings are critical to the work of our Association,” said ATSSA President & CEO Stacy Tetschner. “We lay the groundwork for many efforts and innovations for advancing roadway safety at our committee and council meetings. We were pleased by last year’s record-breaking attendance of 381 and hope to exceed that this year as we work to develop roadway safety plans that utilize the funding approved in the Infrastructure Investment & Jobs Act.”

VDOT starts variable speed limits on northbound I-95

Read ATSSA’s analysis of variable speed zones in Roadway Safety magazine

Pam 0 20194 Article rating: 5.0

The Virginia Department of Transportation (VDOT) takes the first step in activating its variable speed zone along Interstate 95 in the Fredericksburg region today.

New LED signs that can display variable speed limits will be illuminated for the first several days with the 65-70 mph limit to give drivers time to adjust to the presence of the signs, VDOT announced. The system will be fully activated on June 22, at which point speed limits could be anywhere between 35 mph and 70 mph.

ATSSA examined variable speed zones in the Winter 2022 issue of Roadway Safety magazine in an article that analyzed their use in multiple states. The article, “Do They Improve Safety?” reviewed details of how the new VDOT variable speed zone will work and how the zones have been used elsewhere in Virginia and in regions across the country.

The Spring Issue of Roadway Safety magazine is online now and explores Ohio’s Smart Mobility Corridor along Interstate 33 between Dublin and East Liberty.

This 35-mile stretch of roadway in Northeast Ohio is a living laboratory where multiple organizations are testing automated and connected vehicle technology including ways to protect pedestrians. The project is a partnership between private industry and government entities as well as residents in those communities and has been dubbed “the world’s most connected highway.”

Convention Extra is also online and provides a commemorative of the 2022 Convention & Traffic Expo in Tampa, Fla., and an opportunity to see what you missed if you didn't attend this reunion of the roadway safety industry.
