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.

ATSSA submits 120 comments for feedback to proposed MUTCD

ATSSA today submitted 120 comments to the Federal Register on the Proposed Rule for the National Standards for the Traffic Control Devices: Manual on Uniform Traffic Control Devices (MUTCD) for Streets and Highways revision. 

The 23 pages of comments were compiled over the past few months and are the product of input received from ATSSA’s technical committees, MUTCD Chat Lounges during February’s Annual Convention & Traffic Expo, National Committee on Uniform Traffic Control Device (NCUTCD) committee meetings and other conferences attended by ATSSA. The input was produced after sorting through nearly 2,000 comments to the 700-page MUTCD. 

“A huge thank you goes out to our members for leading the charge as this was a herculean effort,” ATSSA Director of Innovation & Technical Services Eric Perry said. “I want to thank our members for their feedback and contributions.”

Comments were due to the Federal Register by Friday.

This is the first comprehensive update to the MUTCD in more than a decade.  The document opened for public comment on Dec. 14 as originally reported here and was originally to allow comments through March 15. The Federal Highway Administration (FHWA) extended the time for public comment as a result of feedback from stakeholders.

The Notice of Proposed Amendments for the 11th edition of the MUTCD contains more than 600 proposed changes, according to a statement from the FHWA.
