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.

Horizon Signal breaks fundraising record with auction

Street Smart Rental makes winning bid in ATSS Foundation fundraiser

Horizon Signal Technologies Inc. raised $53,000 for The ATSS Foundation through the auction of two model SQ3TS trailer-mounted portable traffic signals, setting a fundraising record.

The device offers a 100 mph wind load and a 25-year design life and can be used in a variety of work zone settings, according to device details.

Street Smart Rental, based in Lino Lakes, Minn., made the winning bid of $49,000, with Horizon Signal adding $1,000 to bring the bid total to an even $50,000. In addition, GP Roadway Solutions of Honolulu, Hawaii, which also participated in the auction, donated $3,000, bringing the grand total to $53,000, said Lori Diaz, director of The ATSS Foundation.

Horizon Signal donated 100% of the proceeds from the May auction to The Foundation, which provides education about work zone safety and supports the families of people killed or permanently disabled in work zone incidents. Horizon Signal Technologies, founded in 1988, is based in Reading, Pa. and has seven regional centers in the U.S. plus one each in Canada and Chile. The company specializes in manufacturing portable traffic signal systems and has supported the work of The Foundation for many years.

“We at Horizon believe wholeheartedly in the mission of The Foundation and our hearts go out to the families that have lost a loved one or whose loved one is living with a permanent disability due to a work zone incident,” said company President David Krahulec.

Krahulec is chair of The Foundation’s Board of Directors.

Previously, the largest donation to The Foundation came from PPG/Ennis-Flint, which announced its donation of $30,000 during ATSSA’s 51st Annual Convention & Traffic Expo in February.

The ATSS Foundation is the charitable arm of ATSSA. It was formed in 1988 with the core purpose to promote roadway safety through charitable giving and public awareness programs.

“I am grateful to Horizon Signal for its generosity and to Street Smart Rental and GP Roadway Solutions for participating in the auction,” Diaz said. “We couldn’t achieve our mission without the generosity of people who take part in these events and those who support us in other ways. They enable us to educate people about the importance of work zone safety and support the families affected by work zone incidents through scholarships, the National Work Zone Memorial and other efforts.”
