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.

FHWA seeks ideas for Every Day Counts-5 (EDC-5)

Initiative fast tracks deployment of selected innovations to advance state highways

The Federal Highway Administration (FHWA) is currently seeking innovations and processes for the fifth round of Every Day Counts (EDC-5) from 2019 to 2020.
Ideas submitted by Jan. 18, 2018, have the potential to transform the way the highway transportation community does business by enhancing roadway safety, shortening project delivery time, reducing traffic congestion, and/or improving environmental sustainability. The information also may assist FHWA in identifying proven, market-ready innovations for potential deployment through the EDC-5.

'What if you had an idea or saw an innovation that could save lives? What if research showed this innovation reduced roadway crashes from 19 to almost 50 percent? What if you wanted everyone to benefit? What if? That’s exactly what Every Day Counts did with the innovative road reconfiguration affectionately known as Road Diets. Now it's time to hear about your next ‘What ifs,’” stated Thomas Harman, FHWA Director, Center for Accelerating Innovation.

The EDC program already has advanced five safety innovations into widespread practice over the first three rounds of the program: Data-Driven Safety Analysis; High Friction Surface Treatment; Intersection and Interchange Geometrics; Road Diets; Safety Edge; and currently is promoting Safe Transportation for Every Pedestrian (STEP), under EDC-4.

Responses should be submitted by electronic mail to by Jan. 18, 2018. For ease of submittal, this PDF form may be used.

The FHWA also is gathering ideas and feedback on the Innovations of Interest, identified in its early stakeholder engagement, which includes several safety innovations: Rural Road Traffic Safety, STEP-2.0 – Improving Pedestrian Crossings, and others.

More information on EDC-5 idea submissions and submissions for Innovations of Interest can be found here.
