Cooperative Automated Transportation (CAT)

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.

Deadline extended to July 9 for proposals to lead education sessions at ATSSA’s 2021 Convention

51st Annual Convention & Traffic Expo is confirmed for 2021, likely presented in multiple formats

It’s not too late to submit your proposals to lead education sessions for the 51st Annual Convention & Traffic Expo scheduled for San Diego from Jan. 29 through Feb. 2. ATSSA extended the deadline to July 9 to allow more time for industry experts to provide their insights and expertise during this annual event.

Sessions that can be conducted virtually or pre-recorded are of particular interest as well as topics that address how you dealt with the challenges and opportunities presented by the pandemic, according to ATSSA Training Program Manager Jessica Scheyder.

“ATSSA is committed to holding the event and preparing multiple options for education sessions and all facets of the 51st Annual Convention & Traffic Expo,” said Donna Clark, vice president of Member Services.

ATSSA seeks ideas for education sessions that showcase the best thinking in the field, informed by theory, research and proven best practices. Submissions will provide ways to improve roadway infrastructure safety from a strategic and operational perspective as well as from a tactical approach.

ATSSA’s 51st Annual Convention & Traffic Expo is the premier event for roadway infrastructure safety professionals and transportation officials from across the U.S. and around the globe. In 2020, the Convention brought together nearly 3,700 business leaders, government officials, subcontractors, manufacturers, corporate roadway department personnel, and all disciplines involved in nearly every aspect of roadway infrastructure safety. The event is seen as critical to stay current on trends and industry advancements, access new products and technologies, and stay abreast of legislative priorities and regulatory changes.

Proposals should:

  • Address the importance of roadway infrastructure safety from a strategic perspective;
  • Explore the role of technological innovations in the industry;
  • Speak to new regulations and real-time issues;
  • Provide a preview of industry trends;
  • Identify good practices and cost-effective safety solutions; and
  • Explore essential business practices such as operations, strategic planning, legal concerns, media and crisis training, supervisory and leadership skills, new contract management, hiring and retaining qualified employees.


Submission Process:

  • The Call for Proposals opened Thursday, June 4.
  • Proposals are due Thursday, July 9 at 11:59 p.m. ET and must be completed in the online submission system to be considered.
  • You will receive an automatic confirmation of your submission for your records.
  • All proposals will be reviewed by a group of ATSSA member volunteers and staff who will rate and recommend final selections. Proposals will be selected based on relevance and importance to the continued practice of roadway infrastructure safety.
  • You will be notified no later than Aug. 31 on the status of your proposal.


Presenter Responsibilities:

All accepted presenters must agree to the following rules and responsibilities:

  • Meet all posted dates/deadlines and submit all required items (bio, photo, etc.);
  • Register for the Convention & Traffic Expo (speaker registration is complimentary);
  • Meet all Convention-related due dates and deadlines; and
  • Accept ATSSA’s Speaker Agreement


Take advantage of this opportunity to make essential connections to advance roadway safety.
