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’s 2021 Midyear Meeting kicks off this afternoon in Kansas City, Mo.

More than 300 people have registered for the event that runs through Friday and is being held in hybrid fashion with some attending in person at the Loews Kansas City Hotel and others taking part online.

The week includes the first meeting of the Roadway Worker Protection Council, which takes place Wednesday and evolved from a Roadway Worker Protection Summit held during this year’s Convention and Traffic Expo.

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

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).

Registration now open for Midyear Meeting in Kansas City, Mo.

Registration is now open for the 2021 Midyear Meeting in Kansas City, Mo., Aug. 17-20.

This in-person event takes place at the Loews Kansas City Hotel, located within walking distance of key downtown attractions.

Meet with ATSSA members and industry experts and help shape the Association’s policies and initiatives for the coming year by participating in Midyear committee and council meetings. This event provides opportunities to network and share with more than 300 like-minded ATSSA members from around the country committed to innovation and advancement of roadway safety infrastructure.

AASHTO hosting webinars on results of study on converting MASH to performance-based spec

Pam 0 6652 Article rating: 3.0

The American Association of State Highway and Transportation Officials (AASHTO) is hosting two June webinars to review the results of a study commissioned to explore the possibility of converting the Manual on Assessing Safety Hardware (MASH) 2016 to a performance-based specification.

AASHTO hired the Texas A&M Transportation Institute to do a scoping study to assess the effort, timeline and needs required if the change was undertaken. Results of the study will be presented at two webinars, which will include time for questions. Registration is now open.

MASH scoping study discussed during AASHTO Virtual Spring Meeting 2021

During AASHTO's 2021 Virtual Spring Meeting on Monday, the Council on Highways and Streets (CHS) gathered to provide updates from various stakeholders. The discussion included an update on the Manual for Assessing Safety Hardware (MASH) scoping study to determine the feasibility and potential next steps to convert MASH into a set of performance specifications.

Joyce Taylor from the Maine Department of Transportation (MaineDOT), who serves as design vice chair with AASHTO, gave an update on the MASH scoping study conducted by Texas A&M Transportation Institute (TTI). She discussed the challenges related to current testing procedures and the gray areas within the existing manual that lead to a lack of consistency, as testing may be conducted differently by facilities.

The scoping study, conducted by TTI and sponsored by AASHTO, was completed in April.
