Cooperative Automated Transportation (CAT)

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.

ATSSA continues work on traffic signals membership segment

Pam 0 444 Article rating: No rating

Work continues on incorporating traffic signals into the Association’s activities to advance roadway safety. In 2019, ATSSA formed a Traffic Signals Committee and new membership category during its Midyear Meeting to ensure that the Association is representing all sectors of the roadway safety infrastructure industry and areas related to the Manual on Uniform Traffic Control Devices (MUTCD). It also will allow ATSSA to move forward with new partnerships with traffic signal installers and manufacturers.

Earlier this month, ATSSA President & CEO Roger Wentz submitted a letter to the U.S. House Energy and Commerce Committee and the Senate Commerce, Science, and Transportation Committee, urging legislators to include infrastructure policies as they draft bills related to Connected and Automated Vehicles (CAVs). 

Automation collaboration: Roadway safety infrastructure and automotive industry connections will pave the way to self-driving vehicles

Erica Terrini 0 1324 Article rating: No rating

In recent years, there has been an uptick in collaboration between entities within the roadway safety infrastructure and automotive industries as Connected and Autonomous Vehicle (CAV) technologies progress and enter U.S. roadways. In a sweeping effort to ensure traffic control devices and roadway infrastructure effectively support the Advanced Driver-Assistance Systems (ADAS) of CAVs, manufacturers and groups like the Automotive Safety Council, 3M, SAE International, and ATSSA are working together to uncover the gaps in information and needs to help these vehicles perform at an optimum level.
