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.

Michigan Gov. Gretchen Whitmer wore a button depicting the face of Brandyn Spychalski on her orange suit jacket as she spoke at the national kickoff for National Work Zone Awareness Week this morning.

She urged everyone to recognize that orange work zone cones represent people and to “see the humanity” of one another.

“This is not a hassle. This is not a distraction. This is a workplace,” Whitmer said of roadway work zones. “Each of us deserves to be safe in the workplace.”

National Work Zone Awareness Week (NWZAW) started on Monday with events being held across the country to raise awareness of the importance of work zone safety. The Michigan Department of Transportation (MDOT) hosted this year’s kickoff event, which was livestreamed.

ATSSA thanks FHWA for extending feedback time for proposed MUTCD changes

Association joins other industry leaders in opposing rewrite of MUTCD

Pam 0 7019 Article rating: 2.0

ATSSA President & CEO Stacy Tetschner sent a letter thanking Federal Highway Administration (FHWA) Acting Administrator Stephanie Pollack for extending the comment period for the Notice of Proposed Amendment (NPA) on the Manual on Uniform Traffic Control Devices (MUTCD).

He noted the decade-old MUTCD needs an update, expressed ATSSA’s backing of the process and rejected the recent call by some to rewrite the MUTCD.

“ATSSA supports the ongoing process and we are confident that USDOT will obtain great feedback on how to improve this important manual,” Tetschner wrote. “We understand that some want to start over with the manual and we do not support this idea. We do, however, support a reexamination of the structure, process and content of the MUTCD at a later date. We also want to make it clear that this reexamination should not delay a new edition that our industry desperately needs.”

ATSSA reaches out to state DOTs for help regarding resin shortage

Pam 0 6542 Article rating: 5.0

ATSSA President & CEO Stacy Tetschner today sent a letter to the heads of state Departments of Transportation requesting assistance in light of the current shortage of base resin.

Two major manufacturers of base resin are currently unable to provide the substance used in High Friction Surface Treatment applications due to circumstances beyond their control, Tetschner explains in the letter. He notes that the issue is related to February’s extreme weather events in the Midwest and Texas.

“With US-based materials supply limited, increased costs over the last several months, and a significant delay in shipping overseas materials to the United States, it is likely that some already agreed upon supply contract deadlines will be impacted,” Tetschner states in today’s letter to DOT secretaries across the country.
