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.

Traffic fatalities down in first half of year, National Safety Council estimates

ATSSA president encouraged but not satisfied with reported trend

Pam 0 3721 Article rating: No rating

Traffic deaths showed a 3% decrease for the first six months of this year compared to the same period for 2022, according to National Safety Council (NSC) estimates announced today.

NSC estimated 21,150 people died in motor vehicle crashes between January and June, a report of preliminary estimates shows. The nonprofit conducts semiannual estimates on a regular basis. NSC compares its estimates to those of the National Center for Health Statistics (NCHS) as a means of assessing the validity of its estimates. NCHS’s final estimate of motor vehicle deaths for the first six months of 2021 was 1% below the NSC final estimate—21,771 compared to 21,450.

The Office of Management and Budget (OMB) has released the final guidance related to the Build America, Buy America Act provisions of the Infrastructure Investment and Jobs Act (IIJA). 

This final guidance includes comparisons to the initial guidance from OMB from April of 2022 and responses to comments submitted to the OMB Request for Information from earlier this year. The IIJA expanded current Buy America requirements for infrastructure projects, including the addition of construction materials as a covered category.  

The final OMB guidance directly responds to specific concerns raised by ATSSA.

ATSSA & NCUTCD urge publication of MUTCD without delay

Pam 0 4487 Article rating: 4.0

The National Committee on Uniform Traffic Control Devices (NCUTCD) passed a resolution today recommending the final rule on the Manual on Uniform Traffic Control Devices (MUTCD) not be delayed to address this week’s issuance of a final rule for pedestrian accessibility issues.

The U.S. Access Board on Tuesday issued its final rule providing minimum guidelines for accessibility of pedestrian facilities in the public right-of-way, known as PROWAG.

On May 2, ATSSA President & CEO Stacy Tetschner sent a letter to Federal Highway Administration Administrator Shailen P. Bhatt urging the FHWA to publish the updated Manual on Uniform Traffic Control Devices (MUTCD) by the deadline set forth in the U.S. Code, which was May 15.

ATSSA voted in favor of today’s resolution passed by the NCUTCD.

Integrating wildlife patterns into roadway plans helps save lives

Summer issue of Roadway Safety magazine explores this lifesaving strategy

Pam 0 3224 Article rating: 4.8

With elk, mule deer and pronghorn antelope among the many animals trekking across Wyoming, the state’s Department of Transportation knows the importance of being attuned to their daily movements and seasonal migrations. That information is factored into new road projects to help save the lives of both humans and animals.

The Wildlife Crossings Pilot Program included as part of the Infrastructure Investment & Jobs Act (IIJA) is a new source of funding available to aid such mitigation efforts. The Summer issue of ATSSA’s Roadway Safety magazine, now available online, lays out the cost of human-animal collisions across the nation and examines the details of the program to help members understand how they can become involved.
