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.

FHWA extends comment time for MUTCD NPA

New deadline is May 14

The Federal Highway Administration (FHWA) has extended the time for public comment to May 14 for the first comprehensive update to the Manual on Uniform Traffic Control Devices for Streets and Highways (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 Notice of Proposed Amendments for the 11th edition of the MUTCD contains more than 600 proposed changes, according to a statement from the FHWA.

“The extension is based on concern expressed by a number of stakeholders that, as a result of the scope and complexity of the NPA, the March 15, 2021, closing date does not provide sufficient time to review and provide comprehensive comments,” FHWA said in announcing the deadline extension. “The FHWA recognizes that others interested in commenting may have similar concerns and agrees that the comment period should be extended. Therefore, the closing date for comments is changed to May 14, 2021, which will provide stakeholders and others interested in commenting additional time to discuss, evaluate, and submit responses to the docket.”

ATSSA Vice President of Education and Technical Services Donna Clark said she appreciated FHWA's decision.

“The last manual was published in 2009 and there have been extensive changes since then so it is important that we, as an industry, have sufficient time to review the proposed changes and comment accordingly,” Clark said. “We greatly appreciate FHWA’s willingness to extend the deadline to May 14th and we look forward to working with the ATSSA technical committees to formulate our comments.”
