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.

U.S. rural roads need repairs, modernization and upgrades to support economic growth, report finds

(Fredericksburg, Va) – The rural transportation system in the U.S. is in need of repairs and modernization to stimulate economic growth in communities nationwide, according to a report released today by the national transportation group TRIP.

TRIP’s new report, “Rural Connections: Challenges and Opportunities in America’s Heartland,” assesses the conditions and safety of America’s rural roads and bridges, and states improvements are necessary to resolve rural roadway deficiencies, high fatality rates, a lack of connectivity to other communities or major highways and an inability to accommodate higher traffic volumes.

TRIP studies found 15 percent of U.S. rural roads are in poor condition, 21 percent in mediocre condition, 16 percent are rated as being in fair condition and the remaining 48 percent are in good condition.

The report also showed 10 percent of U.S. rural bridges are considered structurally deficient – having significant deterioration to major bridge components.

Additionally, traffic crashes and fatalities on rural non-Interstate roads are reported to be disproportionately high, two-and-a-half times higher than on other roadways.

“Rural roads account for only about 25 percent of vehicle miles traveled, but 50 percent of roadway fatalities,” said American Traffic Safety Services Association Communications Director James Baron. “Many of these roads have no markings to guide motorists. Installing brighter signs and markings, rumble strips, guardrails, and high friction surfacing treatments on sharp curves will help save lives on these roadways.”

ATSSA feels the implementation of rural transportation improvements in terms of connectivity, safety and overall conditions, would be more attainable if Congress would provide a long-term, sustainable funding solution to entirely support a federal surface transportation program.

“ATSSA members look forward to continuing to work with Congress and the Administration on roadway safety infrastructure solutions, which save lives on rural roads. Ensuring the long-term solvency of the Highway Trust Fund gives states the necessary investments to aggressively tackle and reduce the number of road users killed on rural and urban roadways. A commitment to roadway safety must include fully funding transportation projects and making the Highway Trust Fund solvent. Without solving this funding challenge, we are fighting to reduce fatalities toward zero with one arm tied behind our back,” stated ATSSA’s Vice President of Government Relations Nate Smith.
