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 talks roadway safety during Infrastructure Week, May 13-20

ATSSA advocates for investment in roadway safety infrastructure during awareness campaign

ATSSA is participating in Infrastructure Week this week, advocating as the leader in roadway safety infrastructure.

Infrastructure Week is a national awareness campaign that shares the facts on investing in our nation’s crumbling infrastructure, and advocates for decision makers on Capitol Hill to support infrastructure policy and investment.

“More and more, Americans across the country are supporting increased investments in infrastructure. In 2018, 77 percent of state and local infrastructure ballot measures were approved by voters across the United States. During Infrastructure Week, it’s a crucial time for all of us to spread the message that Safer Roads Save Lives, and roadway safety infrastructure makes a difference. Let’s build for tomorrow, for a future where there are no deaths or serious injuries on our nation’s roadways and families arrive home alive,” said ATSSA’s Vice President of Government Relations Nate Smith.

Partner organizations across the country are sharing the message that we need to #BuildForTomorrow and invest in all areas of infrastructure.

“Roadway safety infrastructure devices save lives each day on our roadways. We call on Congress and the White House to take action in investing in infrastructure; ensuring long-term solvency for the Highway Trust Fund, reauthorizing the highway funding bill, and putting Americans to work manufacturing, installing, and maintaining lifesaving roadway safety infrastructure devices,” said ATSSA’s President and CEO Roger Wentz.

An investment of $146 billion in cost-effective roadway safety infrastructure improvements has the potential to save about 63,700 lives and prevent 353,560 serious injuries over a 20-year time period, according to the AAA Foundation for Traffic Safety. Roadway safety infrastructure improvements that contribute to this figure include median barrier, signalized pedestrian crossings, and shoulder and centerline rumble strips.
