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.

AASHTO and FHWA issue clarifications on implementing MASH 2016

Q and A released for issues raised since May 2018

New information is now available that clarifies issues related to implementing the 2016 edition of the Manual for Assessing Safety Hardware (MASH).

The American Association of State Highway and Transportation Officials (AASHTO) publishes MASH and issued the latest updates in a Question-and-Answer format. The latest information is the result of work produced by a joint technical working group of people from state departments of transportation (DOTs), the Federal Highway Administration (FHWA) and accredited crash testing labs, according to a statement included in the release.

The new Q&A is the result of information compiled since May 2018 to clarify and implement the 2016 edition of MASH.

The information resulted from questions generated by the roadway safety industry about the testing of roadway safety hardware under MASH, according to the AASHTO announcement. The Q & A is intended to provide additional help to manufacturers, crash test labs and DOTs in developing roadway safety equipment.
