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 hosting webinars on results of study on converting MASH to performance-based spec

The American Association of State Highway and Transportation Officials (AASHTO) is hosting two June webinars to review the results of a study commissioned to explore the possibility of converting the Manual for Assessing Safety Hardware (MASH) 2016 to a performance-based specification.

AASHTO hired the Texas A&M Transportation Institute to do a scoping study to assess the effort, timeline and needs required if the change was undertaken. Results of the study will be presented at two webinars, which will include time for questions.

The first webinar is for department of transportation (DOT) and other public agency officials. Registration is now open for this June 14, 2 p.m. EDT session.

The second webinar is for the entire roadway safety industry and is open to all. Registration is now open for this June 25, 3 p.m. EDT session.
