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.

Fall issue of Roadway Safety magazine includes supplement on Worker Protection

Pam 0 15843 Article rating: 5.0

When ATSSA members arrive in Phoenix for the 2023 Convention & Traffic Expo in February they will find themselves in a city that’s made a name for itself as a pioneer in the testing of autonomous vehicle (AV) technologies. The region has embraced the technology and seen multiple pilots for grocery delivery as well as a driverless taxi service.

The Fall issue of Roadway Safety magazine—available online now—details these efforts in Arizona and reveals a resource for members to remove the fear factor from contract negotiations, offers members’ take on the value of in-person advocacy and explains how ATSSA’s ITS Team keeps pace with innovation.

An entire supplement is devoted to roadway worker protection and spells out efforts underway to improve worker safety from multiple perspectives.

Both issues are online now.

The Federal Highway Administration (FHWA) posted the final rule regarding pavement marking retroreflectivity in today’s Federal Register.

The posting states: “The purpose of this final rule is to update the Manual on Uniform Traffic Control Devices (MUTCD) to provide standards, guidance, options, and supporting information relating to maintaining minimum levels of retroreflectivity for pavement markings. The MUTCD is incorporated in FHWA regulations and recognized as the national standard for traffic control devices used on all streets, highways, bikeways, and private roads open to public travel.”

The rule notes that it is effective on Sept. 6.
