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 Convention & Traffic Expo provides vital connections

Event kicks off with panel on prevention and resources for work zone tragedies

FREDERICKSBURG, Va. (Dec. 14, 2020) – ATSSA kicks off its 51st Annual Convention & Traffic Expo with a Roadway Worker Protection Summit, going to the heart of the Association’s lifesaving mission.

The Summit features a panel discussion in which two ATSSA members share the painful experience of losing an employee in a work zone incident. They will discuss resources that helped the employee’s family and their team through the aftermath. They also will talk about tips and tools aimed at preventing work zone injuries and deaths such as training, certification and equipment.

The two-hour Summit is the first session of the 2021 Convention & Traffic Expo, which is being held online over two weeks -- Feb. 8-12 and 16-18.

This year’s virtual Convention will be different from typical online events. It provides ample opportunities for members to connect with industry experts and colleagues in fun and informative ways. The Convention features 45+ education sessions scheduled over seven days and covering everything from tips for handling difficult personnel situations to updates on the latest innovations including connected and automated vehicles.

This year, the Association launches ATSSA’s Got Talent: Battle of the Bands Edition in which members have the opportunity to showcase their musical talents while competing for the title of ATSSA’s Best Band.

Popular features from years past are included in 2021 including the New Products Rollout and the Circle of Innovation where Innovation Award winners get to showcase their products before public agency officials and others in the roadway safety infrastructure industry.

ATSSA’s 51st Annual Convention & Traffic Expo is the premier North American gathering for the roadway safety infrastructure industry and offers roadway safety infrastructure professionals the opportunity to make vital connections across the miles in a fun and engaging environment.

This year’s Traffic Expo includes a virtual exhibit hall where attendees can peruse the latest roadway safety products. It also offers virtual meeting rooms where people can take part in chapter meetups, committee and council meetings and network with others in the industry.

The Convention includes multiple general sessions and an Open Forum on Workforce Development. And, as in years past, ATSSA will announce winners of its annual awards in categories such as the Industry Achievement Award, Mark of Excellence Award and National Safety Award.
