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.

Biden names MassDOT Secretary as FHWA deputy administrator

President Joe Biden appointed Stephanie Pollack as deputy administrator for the Federal Highway Administration (FHWA) today.

Massachusetts Gov. Charlie Baker and Lt. Gov. Karyn Polito announced the departure of Massachusetts Department of Transportation (MassDOT) Secretary and CEO Pollack and named her successor, according to a news release from the governor’s press office today.

Pollack will also serve as acting administrator for FHWA until a permanent administrator is confirmed by the U.S. Senate, according to the release.

Pollack has deep knowledge of both transportation and roadway safety issues. The role of deputy administrator at the U.S. Department of Transportation (USDOT) does not require confirmation by the U.S. Senate so she can begin her new position quickly.

The governor’s office says she will step down from her MassDOT role on Jan. 26 and begin her FHWA position the next day.

The governor thanked her for her service and commended her tenure.

“Stephanie has led MassDOT through many difficult challenges over the past six years; from the historic blizzards that exposed the problems of the MBTA, through saving the GLX project, instituting a data-driven Capital Improvement Plan, and guiding the RMV through a crisis last summer,” Baker said. “She has provided MassDOT with stability and leadership through the last six years, serving longer than her three predecessors combined.”

Some deputy administrators are later named to the top post and then go through the Senate confirmation process. It was unclear if that is the plan for Pollack.

ATSSA Vice President of Engagement Nate Smith welcomed the news.

“We congratulate Secretary Pollack in her new role at the Federal Highway Administration and look forward to working with her to reduce roadway fatalities and serious injuries toward zero in the years to come,” Smith said.
