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.

The Foundation seeks applicants for Experience Camps Travel Scholarship program

Experience Camps Travel Scholarship program to cover round-trip travel expenses to help children coping with loss

(Fredericksburg, Va.) - The American Traffic Safety Services Foundation (ATSSF) is now offering travel scholarships for eligible children to attend Experience Camps.

Experience Camps, a non-profit started in Maine in 2009, offers camps geared toward supporting children of various ages that are coping with grief caused by the loss of a loved one, and to build a support group of young individuals who are undergoing similar challenges.

The Foundation’s mission is to support injured or fallen roadway workers and their families, and to further that goal the non-profit has created the Experience Camps Travel Scholarship program. The scholarship program will cover the round-trip travel expenses for the week-long free camp for eligible children who have lost a parent, sibling, or caregiver in a roadway work zone accident.

Selected children would have their round-trip travel covered for themselves and a guardian (if applicable) to attend any of the four camp locations in the U.S.

The Foundation Manager Lori Diaz is currently seeking eligible children across the country who would like to attend the camp, to apply for the scholarship program.

“The camps give children the opportunity to share their experiences with others who have suffered a similar loss,” Diaz said. “The Foundation supporters and ATSSA members can be part of this too, by simply helping to identify a family who would benefit from such a healing, everlasting experience. We encourage eligible applicants to apply by the July first deadline and to reach out to us with any questions.”

Contact The Foundation Manager, Lori Diaz, for more information about the 2018 Experience Camps Travel Scholarship Program and the application, which can be found at The application deadline is July 1. To learn more about Experience Camps, visit

The American Traffic Safety Services Association (ATSSA) is a proud supporter of The Foundation.
