Cooperative Automated Transportation (CAT)

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.

Report estimates 2020 traffic fatalities highest in 13 years

National Safety Council releases preliminary data on motor vehicle crashes

Pam 0 6547 Article rating: No rating

Fatal motor vehicle crashes in 2020 increased 8% over the previous year despite a drop in driving because of the pandemic, according to a report released this morning by the National Safety Council (NSC).

Preliminary data suggests 42,060 people died and 4.8 million were seriously injured in crashes in 2020, according to the report. The rate of death from that data shows a 24% rise over the previous year though motorists traveled 13% fewer miles. That accounted for the biggest year-over-year increase in 96 years, the report noted.

“It is tragic that in the U.S., we took cars off the roads and didn’t reap any safety benefits,” Lorraine M. Martin, president and CEO of NSC, said in the release. “These data expose our lack of an effective roadway safety culture. It is past time to address roadway safety holistically and effectively, and NSC stands ready to assist all stakeholders, including the federal government.”

The Senate today confirmed former South Bend, Ind., Mayor Pete Buttigieg as Secretary of Transportation, adding him to the cabinet of President Joe Biden.

Buttigieg campaigned on the need for transportation and infrastructure investment throughout his bid to become the Democrats’ nominee for president. During his hearing before the Senate Commerce Committee last month, he touched on the need for shoring up revenue for the Highway Trust Fund (HTF), increased investment in tribal and rural roads, the future of autonomous vehicles and the need for safety to be at the forefront of any new transportation or infrastructure initiative.

The Senate Commerce Committee forwarded his nomination to the full Senate on Wednesday by a 21-3 vote.

The full Senate confirmed Buttigieg’s nomination by a vote of 86-13.
