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.

FREDERICKSBURG, Va. (Feb. 8, 2022) – Transportation Secretary Pete Buttigieg confirmed today that he will deliver keynote remarks at ATSSA’s 52nd Annual Convention & Traffic Expo.

Buttigieg is expected to discuss the National Roadway Safety Strategy released Jan. 27 by the U.S. Department of Transportation (USDOT) as well as provide insights into the Infrastructure Investment & Jobs Act (IIJA) and its impact on roadway safety.

“We are honored that Transportation Secretary Buttigieg is making the time to address our members and we look forward to hearing his insights pertaining to roadway safety and how our industry can partner with USDOT to dramatically reduce roadway fatalities,” said ATSSA President & CEO Stacy Tetschner.

Traffic fatalities make historic increase for first nine months of 2021, NHTSA reports

Pam 0 3736 Article rating: No rating

Traffic fatalities increased 12% for the first nine months of 2021 compared to the same period in 2020, marking the biggest percentage increase in the history of the National Highway Traffic Safety Administration (NHTSA) fatality reporting process, which projects fatality data.

The Fatality Analysis Reporting System (FARS) provides statistical projections for traffic fatalities nationwide, looking at the first nine months of the year in this report that provides an early estimate of motor vehicle traffic fatalities.

The 12% increase is based on an estimated 31,720 people killed in motor vehicle crashes nationwide in the first nine months of 2021 compared to 28,325 killed in the first nine months of 2020. That is the highest number of fatalities for nine months since 2006.

ATSSA reacts to USDOT release of National Roadway Safety Strategy

Pam 0 4268 Article rating: 4.0

The National Roadway Safety Strategy (NRSS) unveiled by the U.S. Department of Transportation (USDOT) on Thursday focuses on moving the U.S. towards zero roadway deaths by taking a safe systems approach that includes six central themes.

The themes laid out are that: deaths and serious injuries are unacceptable; human mistakes are inevitable; humans are vulnerable to injury and death; there is a shared responsibility for these incidents; safety can be and should be proactive; and redundancy is critical. The strategy introduced by Transportation Secretary Pete Buttigieg also focuses on five safety issues.

“ATSSA applauds Secretary Buttigieg on the release of the first National Roadway Safety Strategy, especially with its call for the enhanced protection of roadway construction workers," ATSSA President & CEO Stacy Tetschner said. "Shining a brighter spotlight on the need to dramatically reduce roadway fatalities is critically necessary.”
