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 Convention and Traffic Expo recognized as IAEE Certified Exhibition

(Fredericksburg, Va.) – The American Traffic Safety Services Association’s (ATSSA) Annual Convention and Traffic Expo has been recognized as a Certified Exhibition by the International Association of Exhibitions and Events (IAEE), based on its code of ethics and standards, by continuing to offer educational credits, and by demonstrating consistent verified growth, as well as fulfilling other key criteria.

ATSSA has hosted the Annual Convention and Traffic Expo for more than 40 years. The event hosts more than 3,000 roadway safety professionals and transportation officials from across the U.S. and around the globe. The convention brings together business leaders, government officials, manufacturers, corporate roadway department personnel and others directly involved in nearly every aspect of roadway safety.

"With ATSSA's Annual Convention and Traffic Expo achieving the status of the IAEE Certified Exhibition designation, it has earned the gold standard in the global exhibition industry," Neil Mullanaphy, ATSSA’s director of meetings and conventions, said. "The certification signifies that ATSSA's event has reached the pinnacle of best practices that all exhibitions should adhere to and certifies superior customer service to attendees, exhibitors and contractors. In addition, the designation also means that ATSSA's event complies to scrupulous standards of conduct, performance and 'green' initiatives. It's an honor for ATSSA to be awarded the highest of standards by IAEE."

According to Steven Hacker, IAEE’s certified exhibition program commission chair, certified events meet standards that focus on critical matters such as customer service provided by hosts of these important events.

“The IAEE recently crafted the ‘Gold Standard’ for exhibitions with its Certified Exhibition Program,” Hacker said. “It is intentional that only a very small number of exhibitions of the more than 13,000 that take place each year in the U.S., Canada and Mexico will ever become certified.”

ATSSA’s next Convention and Traffic Expo will be held from Jan. 26 to 28, 2018 in San Antonio, Texas. The event will include hundreds of exhibiting companies showcasing the latest products and services for the industry and a wide variety of traffic safety solutions, state-of-the-art roadway safety vehicles and heavy equipment ranging from striping trucks to truck mounted attenuators. ATSSA’s convention and expo also will include education and information sessions.
