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.

FHWA hosting webinar on pavement marking retroreflectivity final rule

Advance registration required for the free Sept. 1 event

Pam 0 5439 Article rating: 4.2

The Federal Highway Administration (FHWA) is hosting a webinar on “Maintaining Minimum Pavement Marking Retroreflectivity” to discuss the final rule published in the Federal Register on Aug. 5.

The Sept. 1 webinar starts at 12:30 p.m. ET, is free for the public but requires advance registration.

Organizers said the final rule published on Aug. 5 amends the Manual on Uniform Traffic Control Devices (MUTCD), adding provisions for minimum maintained levels of pavement marking retroreflectivity in Revision 3 of the 2009 MUTCD.

Final rule for pavement marking retroreflectivity published

Pam 0 5931 Article rating: 5.0

The Federal Highway Administration (FHWA) posted the final rule regarding pavement marking retroreflectivity in today’s Federal Register.

The posting states: “The purpose of this final rule is to update the Manual on Uniform Traffic Control Devices (MUTCD) to provide standards, guidance, options, and supporting information relating to maintaining minimum levels of retroreflectivity for pavement markings. The MUTCD is incorporated in FHWA regulations and recognized as the national standard for traffic control devices used on all streets, highways, bikeways, and private roads open to public travel.”

The rule notes that it is effective on Sept. 6.

ATSSA strongly opposes President Biden’s gas tax suspension proposal

Maria Robertson 0 3619 Article rating: 5.0

ATSSA President and CEO, Stacy Tetschner released the following statement today that strongly opposes President Joe Biden’s proposal for suspending federal and state gas taxes.

"Although we certainly support efforts to reduce the price per gallon of gasoline and diesel, suspending federal fuel taxes would set a dangerous precedent, financially undermine the recently-enacted bipartisan infrastructure law, impact state and local governments’ certainty of federal roadway safety funding, and imperil the ability to enact future multi-year transportation authorizations. It’s extremely unlikely that the suspension of federal fuel taxes will result in the American consumer actually seeing a commensurate reduction in the price they pay at the pump when filling up their vehicle.

Traffic fatalities rose an estimated 10.5% in 2021, reach 16-year high, NHTSA reports

Trend in fatality rate for vehicle miles traveled decreased for three quarters of 2021

Pam 0 7715 Article rating: 3.0

Traffic fatalities across the U.S. rose 10.5% in 2021 to a projected 42,915 deaths, reaching a 16-year high, according to statistics released today by the National Highway Traffic Safety Administration (NHTSA).

That projected increase from 38,824 fatalities in 2020 is “the highest number of fatalities since 2005 and the largest annual percentage increase in the Fatality Analysis Reporting System’s history,” NHTSA announced today.

ATSSA President & CEO Stacy Tetschner expressed concern over the record-breaking fatality rate.

“ATSSA’s members have devoted their lives to roadway safety and providing the infrastructure and technology needed to save the lives of the motoring public as well as men and women working on our roadways,” Tetschner said. “This unprecedented increase in traffic fatalities brings home the importance of our work and the necessity of government and private industry partnering to provide safe thoroughfares. The bipartisan Infrastructure Investment and Jobs Act (IIJA), which was enacted into law in November, provides historic levels of federal funding for roadway safety infrastructure projects. Departments of transportation around the country, including the U.S. Department of Transportation, must prioritize getting these funds to critical, lifesaving safety projects as soon as possible. We know that safer roads save lives. ATSSA members are ready to go to work with their agency partners to move toward zero deaths on all roads.”

AASHTO and FHWA release answers to help implement MASH

Pam 0 3674 Article rating: 5.0

The American Association of State Highway and Transportation Officials (AASHTO) and the Federal Highway Administration (FHWA) on Monday announced the release of  responses to three questions regarding testing of roadway safety hardware under the Manual for Assessing Safety Hardware (MASH), 2016.

The guidance is available online and includes all new and prior questions and answers dating to May 2018.

A joint AASHTO/FHWA technical working group developed the latest responses, which are created to help manufacturers, crash test laboratories and transportation agencies apply the guidelines to roadway safety devices.
