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 expresses support on bipartisan $2 trillion infrastructure discussion

Congressional leaders and President Trump held productive discussion on infrastructure funding

ATSSA applauds the discussion held between Congressional leaders and President Donald Trump on a $2 trillion infrastructure package.

As the leader in roadway safety infrastructure, ATSSA advocates for investment in roadway safety products that eliminate injuries and fatalities on our nation’s roadways.

The association has called for an infrastructure package that includes roadway safety funding, establishing long-term solvency for the Highway Trust Fund, and increasing funding for the Highway Safety Improvement Program in the upcoming highway reauthorization bill.

“We know that safer roads save lives. We’re encouraged by the bipartisan conversation happening on the federal-level to support infrastructure investment and improvements. Data for 2017 shows that more than 37,000 people were killed in roadway crashes – people just like you and me, trying to get home safely to their families. We call on Congress to work together on a comprehensive infrastructure package that puts Americans to work on making our nation – and roadways – safer,” said ATSSA’s Vice President of Government Relations Nate Smith.

While the meeting is a step in the right direction in making sure our nation’s infrastructure needs are met, funding mechanisms for the package were not discussed. ATSSA supports raising motor fuels user fees, which have not been raised since 1993, and exploring a national pilot program for a vehicle-miles traveled fee system.

ATSSA members from across the country will be in Washington, D.C., May 1-2, 2019, to meet with federal legislators for the annual Legislative Briefing and Fly-In to share their stories and insight on how roadway safety infrastructure saves lives.
