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 0 779 Article rating: No rating

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

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.

Panels discuss innovations and safety challenges during Convention’s first general session

Two industry awards announced as annual Convention starts its second week

Automated vehicles will be mainstream in the next decade, members of an Innovation Panel predicted today during the first general session of ATSSA’s 51st Annual Convention & Traffic Expo.

Timothy Drake, vice president of public policy and regulatory affairs at ITS America, said he expected trucking fleets and public transportation would be the first to take that step and be in place in the 2030s. With that in mind, he said planning needs to take place now within jurisdictions across the country and state departments of transportation (DOTs).

Nazila Roofigari-Esfahan, an assistant professor at Virginia Tech, agreed with Drake but said she hoped it wouldn’t take place before people are ready for it. She said both infrastructure and individuals need to be prepared for that shift in transportation.

The Innovation Panel was one part of today’s general session at ATSSA’s 2021 Convention & Traffic Expo. The session kicked off with a welcome from Board Chair Greg Driskell and the State of the Association Report by ATSSA President & CEO Stacy Tetschner. That was followed by a State of the Industry panel and announcement of two industry awards.

The Federal Highway Administration (FHWA) has extended the time for public comment to May 14 for the first comprehensive update to the Manual on Uniform Traffic Control Devices for Streets and Highways (MUTCD) in more than a decade.

The document opened for public comment on Dec. 14 as originally reported here and was originally to allow comments through March 15.

The Notice of Proposed Amendments for the 11th edition of the MUTCD contains more than 600 proposed changes, according to a statement from the FHWA.
