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 hosting webinar on pavement marking retroreflectivity final rule

Advance registration required for the free Sept. 1 event

The Federal Highway Administration (FHWA) is hosting a webinar on “Maintaining Minimum Pavement Marking Retroreflectivity” to discuss the final rule published in the Federal Register on Aug. 5.

The Sept. 1 webinar starts at 12:30 p.m. ET, is free for the public but requires advance registration.

Organizers said the final rule published on Aug. 5 amends the Manual on Uniform Traffic Control Devices (MUTCD), adding provisions for minimum maintained levels of pavement marking retroreflectivity in Revision 3 of the 2009 MUTCD.

After registering, participants will receive an email confirmation with the webinar link. The link is unique to the person who registered and should not be shared with others. However, groups wishing to watch together can fill out one registration.

Points of contact for additional information on the final rule are available here.
