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.

ATSSA & NCUTCD urge publication of MUTCD without delay

Pam 0 4612 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.

Final rule issued for accessibility of pedestrian facilities in public right-of-way

Pam 0 2513 Article rating: 2.8

The Architectural and Transportation Barriers Compliance Board (Access Board) today issued its final rule providing minimum guidelines for accessibility of pedestrian facilities in the public right-of-way, known as PROWAG.

These final guidelines have been long awaited, in particular by state and local governments that have sought them for more than 30 years.

The final rule for PROWAG was published in the Federal Register and is effective Sept. 7. Once adopted, the guidelines “would ensure that facilities used by pedestrians, such as sidewalks and crosswalks, constructed or altered in the public right-of-way by federal, state, and local governments are readily accessible to and usable by pedestrians with disabilities,” according to the posting.

NCUTCD summer meeting provides traffic signals, VRU, MUTCD updates

Pam 0 7220 Article rating: No rating

The National Committee on Uniform Traffic Control Devices (NCUTCD) summer meeting addressed a variety of topics including traffic signals and vulnerable road users and provided an indication that work is progressing on the updated Manual on Uniform Traffic Control Devices (MUTCD).

In May, ATSSA President & CEO Stacy Tetschner sent a letter to Federal Highway Administration Administrator Shailen P. Bhatt urging the FHWA to publish the updated MUTCD by the May 15 deadline set forth in the U.S. Code. Tetschner acknowledged the "tremendous amount of work” needed to update the MUTCD but said he wanted to “stress how vital it is that this statutory deadline is met.”

Toward the end of the summer meeting of the NCUTCD, also referred to as “the National Committee,” federal officials made reference to August, suggesting work on the final rule is moving forward. However, there was no commitment that it would be published that month.
