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.

Roadway safety is critical focal point of future transportation legislation

ATSSA Chair urges House subcommittee to include policies in infrastructure package, address long-term solvency of Highway Trust Fund

On Wednesday, Oct. 11, ATSSA Chair Debra Ricker submitted written testimony to the House Subcommittee on Highways and Transit, highlighting ATSSA's strong belief that roadway safety must remain a critical focal point of any new transportation legislation. The subcommittee held a hearing entitled “Building a 21st Century Infrastructure for America.”

Chair Ricker's testimony centered on the need to not only include roadway safety infrastructure policies and language in the future infrastructure package but also the need to address the long-term solvency of the Highway Trust Fund. The subcommittee’s Chairman Sam Graves (R-Mo.) and Ranking Member Eleanor Holmes Norton (D-D.C.) have been leaders on this issue, repeatedly urging the House Ways and Means Committee to address the Highway Trust Fund during their tax reform negotiations.

The ongoing tax reform legislation is a prime opportunity to not only fund the Administration's infrastructure proposal but also to finally address the lingering question of how we fund federal transportation projects in our country.
