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.

Register at Convention to play a role in advocating for roadway safety

ATSSA’s Legislative Briefing & Fly-In set for April 18-19 in the nation’s capital

ATSSA’s 2023 Legislative Briefing & Fly-In offers members the opportunity to play a role in advocating for roadway safety at the national level.

This annual event, which is an exclusive member benefit, takes place April 18-19 in Washington, D.C. Members will have the opportunity to deliver roadway safety solutions to the Capitol Hill offices of lawmakers and their staffs, who craft policy that affects the roadway safety infrastructure industry for years to come.

This year, both House and Senate office buildings are fully open to visitors.

“We look forward to having ease of access to Capitol Hill offices this year,” said ATSSA Vice President of Engagement Nate Smith. “Our team works diligently to set up multiple meetings with legislators for every person attending this important advocacy event. We recognize the importance of face-to-face advocacy with legislators and have seen the benefits for our members and the industry.”

This year’s Legislative Briefing & Fly-In coincides with National Work Zone Awareness Week (NWZAW), which will be held April 17-21 and has the theme, “You play a role in work zone safety. Work With Us.”

ATSSA members will have the opportunity to raise awareness of work zone safety while encouraging legislators to work with us to develop lifesaving policy for the nation’s roadways. Members can play a role in roadway safety by participating in the Legislative Briefing & Fly-In, April 18-19.

Online registration is now open. Members can also register during ATSSA’s 53rd Annual Convention & Traffic Expo, which runs Feb. 17-21. A $750 scholarship for the first 10 first-time attendees who register and attend the event is available.

Housing registration is also open at the Pendry hotel, located at 655 Water St., SW, Washington, D.C. 20024. Reserve housing by March 17. ATSSA cannot guarantee room availability or reduced rates after that date. The Legislative Briefing will be held at the hotel on April 18 as well as an ATSSA PAC meeting that evening.

Members are responsible for housing and transportation costs.
