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.

AASHTO provides update on MASH-compliant devices

Pam 0 481 Article rating: No rating

The American Association of State Highway and Transportation Officials (AASHTO) recently issued information about new Manual for Assessing Safety Hardware (MASH)-compliant devices that have been granted federal aid eligibility letters.

The AASHTO communication from Director of Engineering Jim McDonnell was issued to provide an update on roadway safety devices now on the market and approved under federal guidelines.

ATSSA endorses Auto Alliance’s commitment to preserve bands of spectrum for transportation safety

Pam 0 843 Article rating: No rating

ATSSA President & CEO Stacy Tetschner sent letters to Federal Communications Commission Chair Ajit Pai and U.S. Department of Transportation Secretary Elaine Chao this week strongly endorsing the Alliance for Automotive Innovation’s letter committing to fully utilize the bands of spectrum allocated for transportation safety.

“The commitment undertaken by the Auto Innovators reflects a watershed moment for roadway safety. This letter demonstrates a unified industry committing substantial resources and support for Vehicle-to-Everything (V2X). This approach should dispel any notion that the industry will not deploy V2X or that the Safety Spectrum will not be used,” Tetschner wrote.

FCC extends deadline for replies to comments on 5.9 GHz band proposal

Pam 0 1018 Article rating: No rating

The Federal Communications Commission’s Office of Engineering and Technology granted a 21-day extension of the deadline for submitting replies to comments regarding a proposed rule change regarding the 5.9 GHz band, also commonly referred to as the "safety spectrum."

The new deadline of April 27 resulted from the extensive comments submitted and disruptions caused by COVID-19.

National Work Zone Awareness Week still on for April 20-24

Michigan DOT cancels kickoff event due to COVID-19 concerns

Pam 0 905 Article rating: No rating

National Work Zone Awareness Week will continue as scheduled on April 20-24. However, Michigan officials canceled the April 21 kickoff event in accord with CDC guidelines regarding the coronavirus pandemic.

As of Sunday, the CDC recommended groups not hold gatherings of 50 or more people for the next eight weeks. Michigan Department of Transportation (MDOT) officials discussed the issue with ATSSA today. It was agreed that MDOT will instead host next year’s event. Virginia DOT had been scheduled to host in 2021 but will now host in 2022.
