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.

VTTI seeks participants for survey on how connected and automated vehicles will interact with work zones

Pam 0 5864 Article rating: 3.5

Luke Neurauter, senior research associate in the Division of Vehicle, Driver and Safety Systems at the Virginia Tech Transportation Institute (VTTI), is asking ATSSA members and others in the roadway safety industry to take part in a survey on the impact of connected and automated vehicles (CAVs) on work zones.

The purpose is to “better understand how CAV technologies will behave when they encounter typical work zone scenarios and what can be done (from the perspectives of both the CAVs and work zone operations) to ensure ultimate compatibility between all available technologies,” according to information from VTTI Senior Research Associate Tammy Trimble.

The research is sponsored by the Transportation Research Board (TRB).

CAT Coalition working group shares research on AV issues, primer plans

Participants share impacts of AVs on highway infrastructure and report on U.S. readiness

Pam 0 6524 Article rating: No rating

Members of the Cooperative Automated Transportation Coalition Infrastructure-Industry (CAT I-I) Working Group shared recently that they are assembling a primer with acronyms and definitions for autonomous vehicle (AV) and connected vehicle (CV) infrastructure and technology.

The primer is not the first of its kind but intended to “bridge the gap” between Infrastructure Owner-Operators (IOOs) and Original Equipment Manufacturer (OEM) practitioners, according to the CAT I-I working group members.

The working group's recent meeting also included presentations by Ted Hamer, managing director at KPMG Corporate Finance, and Paul Carlson, chief technology officer at Road Infrastructure Inc.

USDOT releases 'Automated Vehicles Comprehensive Plan'

The plan is available on the Federal Register for public comments

Pam 0 6805 Article rating: No rating

The U.S. Department of Transportation this week released an “Automated Vehicles Comprehensive Plan”  (AVCP) that details a multi-pronged approach that “prioritizes safety while preparing for the future of transportation,” according to a statement announcing the plan.

“This comprehensive plan lays out a vision for the safe integration of automated vehicles into America’s transportation system while ensuring that legitimate concerns about safety, security and privacy are addressed,” Transportation Secretary Elaine L. Chao said in the statement.

Public comments should be made within 60 days of the posting.

FCC votes unanimously to redistribute a portion of the safety spectrum

ATSSA and other roadway safety advocates opposed changes to 5.9 GHz band

Pam 0 7499 Article rating: 5.0

The Federal Communications Commission (FCC) voted unanimously today to reallocate more than half of the 5.9GHz spectrum band—known as the “safety spectrum”—to unlicensed uses including WiFi.

The new rules adopted today make the lower 45 megahertz of the spectrum available for unlicensed uses. They require Intelligent Transportation System (ITS) licensees to stop using this portion of the spectrum within a year.

ATSSA President & CEO Stacy Tetschner called the action "a major blow to the roadway safety community and public safety in general."
