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.

National contest challenges transportation/engineering students to improve roadway safety

(Fredericksburg, Va.) – The American Traffic Safety Services Association (ATSSA) has announced the second annual “Traffic Control Device Challenge,” which offers its winners cash prizes and national media recognition for their progressive ideas.

In partnership with the Transportation Research Board (TRB), ATSSA is asking engineering students to focus on how America’s roadway system can be made safer – through innovation – to accommodate road users of all types.

During the first year of the contest, students from Pennsylvania State University, New Mexico State University and the University of Arizona also had the opportunity to display their ideas to the roadway safety industry during ATSSA’s Annual Convention and Traffic Expo in Phoenix, Arizona.

“For the second annual competition, we are seeking three new finalists to carry the torch to the next level of innovation and technology,” said Dr. Paul Carlson, senior research engineer at Texas A&M Transportation Institute.

Eligible participants can be high school, community college, college, graduate students, or teams of students who have an interest in transportation infrastructure safety.

“There are numerous transportation issues across the country that would welcome fresh, creative innovate ideas, or products and services to help improve our nation’s roadways for all road users,” said ATSSA’s Communications Director James Baron. “For example, as we see connected and automated vehicles becoming reality more and more each day, our nation’s transportation system must be prepared to meet the demand of those motorists and those vehicles. Work zone safety is another area that we are constantly seeking improvements in.”

Submissions to the contest must be an original design or modification of an industry-accepted design or product. A special panel of TRB experts will then judge entries based on the ability of the idea to address a specific roadway problem, how easily it can be understood by all road users, its applicability on a nationwide basis, and its feasibility for implementation.

Up to 12 finalists will be invited to display their ideas at the 2018 TRB annual meeting in Washington, D.C. in early 2018. From those, first, second and third place winners will be selected to present their concepts to the roadway safety industry at ATSSA’s 48th Annual Convention and Traffic Expo in San Antonio, Texas, from January 26-30, 2018.

“We’re looking for new ideas to make our roadways safer and more efficient for all road users,” said Carlson.

Submission deadline for all students is Oct. 1. Interested students who wish to participate can find an application packet at http://expo.atssa.com/.
