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 endorses bipartisan Senate bill aimed at improving rural road safety

Senators Kelly and Burr just introduced the legislation on Capitol Hill

FREDERICKSBURG, Va. (May 20, 2021) – Sen. Mark Kelly (D-Ariz.) and Sen. Richard Burr (R-N.C.) today introduced legislation known as the “High Risk Rural Roads Safety Act of 2021.” The bipartisan proposal would increase funding for the Highway Safety Improvement Program (HSIP) and create a $750 million HSIP set-aside directed solely for safety projects on high-risk rural roads, with $150 million of that directed to tribal lands.

The American Traffic Safety Services Association (ATSSA) endorsed the bill that would ensure safety becomes a priority for locally owned rural roads in order to address the significant safety challenges in rural America.

The funding would be directed to rural, locally owned roads, which often lack the critical safety infrastructure this legislation would help ensure is provided. According to the U.S. Department of Transportation (USDOT), the fatality rate on rural roads is two times greater than on non-rural roads.

“ATSSA applauds Sens. Kelly and Burr on their leadership on rural and tribal road safety issues in the Senate,” ATSSA President & CEO Stacy Tetschner said. “If we are going to achieve our long-term goal of zero fatalities, we must address safety challenges on all roads, including rural and tribal roads. ATSSA’s members are eager to work with the senators on reducing fatalities and serious injuries in rural America.”

In addition to ATSSA, the American Highway Users Alliance, American Society of Civil Engineers (ASCE), National Association of Counties (NACo), National Association of County Engineers (NACE) and the National Association of Development Organizations (NADO) endorsed the legislation.

The rural road safety projects that this legislation focuses on are those that are eligible under HSIP.

“Arizona ATSSA members are thrilled that Sens. Kelly and Burr have introduced this legislation and are leading the Senate effort to address rural and tribal road safety challenges here in Arizona and across the country,” said Juan Arvizu of Pavement Marking Inc. in Tempe, Ariz., the immediate past chair of ATSSA’s Board of Directors. “As an industry, we’re marching toward zero deaths on U.S. roads and Sens. Kelly and Burr are leading that effort with us.”
